IMPORTANT NOTES:  
1. The MX88 System can be a single controller with keypads for up to Eight zones or two connected controllers  
and keypads for up to Sixteen zones.  
All the set up details for a MX88 are stored in a file called “Project”.  
The MX88 can be set up without a PC, using the QuickConfig protocol, via the keypad or touchpanel connected  
to the Zone 1 keypad port of the MX88. By using QuickConfig, you can set up an eight zone or an expanded 16  
zone MX88 system without ever having to hook up a PC.  
However, please note that Projects created by QuickConfig cannot be retrieved and/or edited in Universal  
Dragon.  
The MX88 can also be set up and customized using Xantech‟s Universal Dragon Windows® software.  
There are two different setup modes in the Universal Dragon:  
-
-
The Advanced mode allows customization of system configuration for functions such as zone linking,  
monitor lockout, unique IR programming by zone, etc.  
The Expanded mode allows programming of systems with more than eight zones using two linked  
MX88 Controllers.  
Each section of this manual will indicate which sections apply to the different programming modes and setups.  
In the Expanded mode, the controller for zones 1-8 will be referred to as the PRIMARY CONTROLLER. The  
controller for zones 9-16 will be referred to as the SECONDARY CONTROLLER.  
2. All programming and features of the MX88 directly apply to all models except:  
Video Distribution and Video Sensing applies to MX88vi models only  
Ethernet/IP applies to MX88vi or MX88ai

SYSTEM OVERVIEW  
In a MX88-based whole house audio/video/control system, the MX88 controller/amplifier acts as the server and  
the keypads, touch-panels, and compatible web-enabled devices (such as the Apple® iPad®) act as the clients.  
The end users interact with these clients in order to control all aspects of audio/video distribution and control.  
This system allows the end user to accomplish the following: 1) Distribute amplified audio and video from eight  
independent Sources to eight separate zones. 2) Control the volume, mute, bass, treble, and balance for each  
of the eight zones. 3) Control most standard source components via IR and/or RS232 and/or IP (certain MX88  
models only) commands. Two MX88s can be linked to create systems with up to sixteen zones.  
Figure 1 - System Block Diagram  
There are many ways in which the MX88 can be controlled or to control audio, video and home control systems:  
By pressing the buttons on the MX88 keypad or touch-panel  
From signals received from an Infrared (IR) remote at the keypads IR Receiver eye  
From RS232 control from a touch screen panel or other RS232 controller device

Section 2: Installation & Connections  
INSTALLATION  
Installing an MX88 system involves completely planning the system from hardware, installation, and  
programming standpoint, before the actual installation begins.  
We strongly recommend, before physical installation begins, that all the actual components to be used as part  
of the MX88 system are physically connected and tested individually first, and then tested again as a system  
with a fully programmed and configured MX88. This added effort can become a valuable investment in quick  
and effective troubleshooting in case any issues are encountered after installation.  
We also recommend that all installed wiring is checked thoroughly and systematically for continuity and  
integrity, using proper test equipment designed for the specific type of wiring.  
OPERATION: OUT-OF-THE-BOX PRE-TEST  
The MX88 is shipped to operate basic functions „Out-Of-The-Box‟ without any programming. Simply by plugging  
in keypads via standard CAT-5 RJ45 terminated patch cable and powering the controller „on‟, you can control  
Source Selection, Volume Up/Down and speaker Mute capabilities.  
Completing the Out-Of-The-Box Pre-Test will verify that all sources and zone components are working properly  
to select and distribute audio and video prior to programming via QuickConfig or with the Universal Dragon.  
This will ensure that the unit is indeed functioning correctly „prior‟ to fixed installation and allow proper  
troubleshooting procedures if a problem is encountered. Instructions regarding full programming for specific  
components and features will follow.  
Notes:  
-
-
For Expanded, 16-zone configuration, test both units individually as outlined below.  
For simplicity of test set-up, only one Source Component, one pair of speakers, and one TV/Video  
Monitor will be necessary.  
For the pre-test the MX88, you will need the following:  
.

9. Repeat Steps 5 thru 8 for source/Zone 2 thru 8  
Caution: Power voltage for the keypad is transmitted along the CAT5 cable! Incorrect wiring on this cable  
can destroy the keypad or touch-panel. Please test the cable connections using a proper CAT5  
cable tester or using a multimeter to check Pin to Pin continuity and for possible shorts. Using either  
method, it is advisable to measure pins 3 and 6 to verify proper voltage with a multimeter. A 12Vdc  
measurement should be read when the positive probe is on pin 6 and the negative probe is on pin 3.  
See Figure 10.  
MX88 CONTROLLER/AMPLIFIER PHYSICAL LOCATION  
1. The MX88 is convection cooled. It depends on the natural free flow of air up through its slot perforations in  
and over the internal heat dissipating fins for adequate cooling.  
2. Should adequate cooling be desired, external fans and other means of air ventilation can be used.  
3. Once installed, your MX88 will have large bundles of wire and cable to accommodate audio, video and  
speaker connections. Be sure to allow enough room for the leads and dress them in such a manner so as  
not to block airflow.  
4. The MX88 is designed for mounting on flat horizontal surfaces.  
5. Do not remove chassis feet. They are necessary to provide proper ventilation.

IR CONTROL CONNECTIONS  
8-zone system:  
Plug the supplied 283D IR emitters into the appropriate IR Emitter jacks - Figure 3-(26). Take care to match  
the source audio and video connection number on the MX88 to the IR Emitter jack number. This will ensure  
that the IR control signal will be routed to the correct source component. Find the IR sensor window on the  
source component and attach the emitter to the components sensor window after removing the protective  
paper cover on the flat side of the emitter head. A Common IR jack is also provided for connection to other  
auxiliary devices that are not source specific - Figure 3 item 27.  
Expanded, 16-zone system:  
Connect the emitters to the Primary Controllers IR Emitter jacks - Figure 3 item 26 as noted above.  
Note: The appropriate source IR Emitter of the Secondary Controller will also flash regardless of what  
zones keypad issues the command but it is recommended to use the emitter jacks of the Primary unit.  
SENSE INPUT CONNECTIONS  
8-zone system:  
The sense input connection will typically be used to sense the power state of a source component using  
any of the Xantech Sense Modules (sold separately). Plug the 3.5mm mini plug from the Xantech sensor  
into the appropriate sense jack Figure 3 item 22. Take care to match the source audio and video  
connection number on the MX88 to the appropriate sense jack number. Please refer to instructions included  
with the specific sensor that you are using for set up and any necessary adjustments.  
Expanded, 16-zone system:  
Connect the Xantech sensors as described above to the Primary Controller. Sense inputs on the Secondary  
Controller are inactive and are not to be used.  
BI-DIRECTIONAL CONTROL PORTS  
RS232 Ports 1 and 2:  
These DB15 ports, when used with the included DB15-to-DB9 adaptor cables, can be used for controlling  
and receiving status information/metadata from external devices and components, or for allowing external  
devices to control the MX88. Port 1 can also be used to link one MX88 to another, using the supplied DB15-  
to-DB15 expansion cable, creating a 8 source/16-zone “Expanded” system.  
Ethernet jack (MX88vi and MX88ai only):  
Used for connection to a Local Area Network, and allowing control of all the zones of MX88vi or ai from  
almost any wired or wireless IP-enabled device with web browsing capabilities, such as the Apple® iPad®,  
Windows® and Android™ tablets, and PCs. It also allows for some limited 2-way external device control,  
subject to expansion in the future. The MX88 comes with DHCP enabled so that it can be accessed through  
a dynamically enabled network. Its address should be fixed to a fixed IP address that is supported by your  
Local Area Network, using the MRIP Installerprogram that can be downloaded at  
Start” document at the same URL for details.  
ZONE RELATED WIRING CONNECTIONS  
In typical applications, each zone will have at least one MX88 keypad or touch-panel, and a pair of  
speakers. In zones with both audio and video (MX88vi), at least one video monitor or television will also be  
used. In order to make these connections, the minimum requirement is home runs of one CAT5 cable for  
each zone‟s keypad(s), two pairs of 12-18AWG wire for each pair of speakers, and one coaxial cable for a  
TV or monitor (MX88vi) from each zone to the MX88 Controller/Amplifier location.  
SPEAKER CONNECTIONS  
1. Using good quality speaker wire, connect the individual speaker leads to the 4-terminal "SPEAKER"  
connectors on the MX88 as shown in Figure 3 item 22.

Page: 18  
Model MX88  
2. The MX88 Speaker Terminals (amplifier outputs) are 4-Ohm compatible. Make sure the combined  
impedance presented to the speaker terminals by the speakers (or any combination of speakers) is 4-  
Ohms minimum.  
3. Be sure to observe correct polarity by connecting the "+" and "" terminal from each channel on the  
MX88 to the corresponding "+" and "" terminals on each speaker. This will ensure proper speaker  
polarity and have the left and right speakers operate “in phase”. These connectors are removable, so  
you may unplug them for ease of speaker wire lead assembly.  
4. As a rule of thumb, use 18 gauge speaker wire for speaker runs up to 30' (9m), 16 gauge up to 70'  
(21m), and 14 gauge up to 150' (39m). The 4-terminal connectors accept wire sizes up to 12-gauge.  
5. Strip the insulation back about 1/4" (6mm) and twist the strands on each lead to prevent fraying.  
6. Speaker Polarity: To obtain stable imaging and full bass response, it is imperative that stereo speakers  
be connected "in phase" with each other. You can verify this as follows:  
a) If the "+" (positive) and "" (negative) terminals on your speakers are correctly marked, and visible,  
and you have wired the system with the positive connector on the rear of the MX88  
Controller/Amplifier connected to the positive connector on the speaker and the negative connector  
on the rear of the MX88 Controller/Amplifier connected to the negative connector on the speaker,  
then the system will be "in phase". No further action is required. Most manufacturers identify the  
positive terminal with a red binding post, a "+" sign, or a red dot.  
b) If you are unsure of the markings, you can verify that your speakers are in phase (but not the  
absolute polarity of each speaker). Using a mono sound source, such as AM radio, alternately  
reverse the leads to one of the speakers. Pick the connection that delivers a solid center image  
between the speakers as well as best bass response.  
CAUTION: After lead ends are inserted and the screws tightened down, be sure there are no free  
strands that could cause shorting!  
MX88 KEYPAD CAT5 CABLE CONNECTIONS AT THE MX88 CONTROLLER/AMPLIFIER  
NOTE: While we use the term CAT5 throughout this manual, CAT5/5e/6/7 may be used to connect the MX88 to  
Xantech keypads and touch-panels. Bear in mind that cable quality may reduce maximum lengths quoted  
throughout this manual or in the keypad or touch-panel manuals.  
The MX88 utilizes „Pin-to-Pin‟ CAT5 cabling for its wired zone controllers (MX-compatible keypad or touch-  
panel) that can be purchased pre-fabricated at fixed lengths or self-assembled to custom lengths. The color-  
coded wiring standard is EIA/TIA 568B as shown in Figure 4. The plastic connector on the end of the CAT5  
wire is “registered jack” RJ45.  
1. See Figure 4 for proper termination of the CAT5 cables to the RJ45 connectors.  
2. Connect the zone keypad to the appropriate zone Keypad connector on the rear of the MX88  
Controller/Amplifier Figure 3 item 16.  
Caution: Operating voltage for the keypad is transmitted along this cable! Incorrect wiring on this cable can  
destroy the keypad or the touchpanel! Be sure to test cable for proper connections before making connections.

Figure 4 - CAT5 Pin Assignments (per EIA/TIA 568B) Pinned 1:1  
VIDEO CONNECTIONS (MX88VI ONLY)  
1. When running composite video to a TV or monitor, use RG6 coaxial or RG59 quad-shield cable with  
RCA-type phono plugs on each end. This connection can be run up to 150 feet, as this is a buffered  
video output from the MX88 Controller/Amplifier.  
2. Connect the zone video cable to the appropriate zone video jack on the rear of the MX88vi Controller/  
Amplifier Figure 3 item 18.  
STATUS CONNECTIONS AND COMMON CONTROL OUT  
Status  
Each zone has a Status Output Figure 3 item 19, that provides a control output of +12 VDC, 50mA that  
turns ON and OFF with the zone ON/OFF condition. ON = +12VDC, OFF = 0VDC. Using a 3.5mm mono  
mini phone connector, this control can be used to close a relay, such as a Xantech CC12, to raise a TV lift  
or drop a projection screen automatically when a zone is turned ON. Connect one end of the 3.5mm Mono  
Mini jack to the appropriate zone Status connector on the rear of the MX88 Controller/Amplifier and the  
other end to the device to control. Tip=Control Voltage; Sleeve=GND  
Control Out  
A single Common Control Output is provided on the rear of the MX88 Controller/Amplifier Figure 3 item  
20. When the Common Control Output is High (+12VDC, 50mA max.), this indicates that at leastone zone  
is powered ON. When the Common Control Output is Low (0VDC), this indicates that allzones are OFF.  
Using a 3.5mm mono mini phone connector, this control can be used to close relays (such as Xantech  
CC12) or turn on an AC outlet (such as Xantech AC1 or AC2) for activity common to the system. Connect  
one end of the 3.5mm Mono Mini jack and the other end to the device to control. Tip=Control Voltage;  
Sleeve=GND  
Expanded, 16-zone system:  
When at least one zone on either the PRIMARY or SECONDARY controller is turned ON, the Control Out  
on the PRIMARY Controller is High (+12VDC, 50mA max.). The Control Out on the Secondary Controller is  
inactive in Expanded mode.

Model MX88  
PREAMP OUT  
Each zone has a Preamp Out to send „zone selected‟ audio to an outboard power amplifier such as the  
Xantech PA4100x. This may be needed for powering a sub-zone, or for use in zones that require more than  
50W a channel, or for sending audio to another amplifier with Dolbysurround decoding for „theater  
quality‟ audio in that zone.  
Using good quality RCA-type patch cables, connect the Preamp Out, Left (L) and Right (R) connectors –  
Figure 3 item 25, to the desired external amplifiers Audio Left and Right Input connectors.  
CO1 AND CO2 (ZONES 7 & 8)  
Zones 7 and 8 have a Remote Mute/Standby output for interfacing and controlling an external power  
amplifier, such as the higher powered PA4100x. The control is provided via a Stereo Mini Jack with the “tip”  
of the mini-phone connector controlling “standby” logic (Power On = +12VDC, Power Off = 0VDC) and the  
“ring” controlling “mute” logic (Mute = +12VDC, Un-Mute = 0VDC).  
Using a 3.5mm stereo mini Jack to 3.5mm stereo mini Jack cable, plug one end into the CO1 (or CO2)  
output jack on the rear of the MX88 Controller/Amplifier Figure 3 item 21 and the other end into the  
corresponding jack labeled CO1 (or CO2) on the Xantech power amplifier.  
NOTE: If using a Xantech PA4100X amplifier, be sure to set the Control In (CI) switch to ON located on the  
rear panel of the amp.  
ZONE IR  
Using Xantech emitters (282D, 283D,284D, 286D, etc.), plug the 3.5mm mono mini jack into the  
appropriate zones Zone IR connector Figure 3 item 28. Affix the emitter side to the desired zone related  
component you wish to control. If more than one device needs to be controlled, use a mono mini to  
stripped-ends wire (p/n 6015900) wired to a Xantech 791-44 Amplified Connecting block. Any IR from the  
zone (generated by the touch-panel, received at the keypad or touch-panel and passed through, or routed  
from another zone (set up via Universal Dragon only) will be outputted from this emitter port.  
AC POWER CONNECTIONS  
Use one of the supplied AC power cords specific to your region or country, insert it into the AC inlet on the  
back panel of the MX88, and plug into a power source capable of delivering the rated current and power  
stated on the back panel of the MX88.  
CONNECTIONS AT THE ZONE LOCATION  
KEYPAD CONNECTIONS AND JUMPER SETTINGS  
Single Keypad CAT5 Connections  
1. Refer to Figure 4 for proper termination at the zone-end of the CAT5 cable.  
2. Set Keypad Address, using specific instructions provided in the manual for that specific keypad.  
2. Connect the CAT5 cable from the MX88 Controller/Amplifier into the RJ45 jack marked “Controller” on  
the rear of the MX88 keypad.  
Caution: Power voltage for the keypad is transmitted along this cable! Incorrect wiring on this cable can  
destroy the keypad or touch-panel! Be sure to test cable for proper connections before making connections.  
Multiple Keypad Connections  
1. For a second keypad in the same zone, terminate the CAT5 cable in the same way as shown in Figure  
4.  
2. Connect the CAT5 coming from the MX88 Controller to the “CONTROLLER” jack on the Primary  
Keypad. Plug a CAT5 cable into the “EXPANSION” jack on the Primary Keypad and connect it to the

“CONTROLLER” jack on the Secondary Keypad. Repeat for all keypads in zone (up to a total of 4  
Keypads). Each of the 4 keypads or touch-panels within a zone must have a unique address that is not  
shared by the other three keypads.  
Zone Termination  
The LAST keypad connected in the zone (Keypad with no other keypad plugged into its EXPANSION  
port) must have the Zone Termination Jumper installed. Please see the keypad or touch-panel‟s  
manual for specifics.  
Sensor Enable  
To disable the keypad or touch-panel‟s on-board IR Receiver, remove the Sensor Enable jumper on  
the rear of the keypad. Please see the keypad or touch-panel‟s manual for specifics.  
External IR Terminal Block  
To conveniently add other Xantech IR Receivers or IR keypads (such as SmartPad or WaterPad) in  
conjunction with the MX88 Keypads, you may wire 18AWG-24AWG 4-conductor wire, directly to the  
terminal block on the rear of the Keypad. Please see the keypad or touch-panel manual for specifics. A  
4-conductor connector is provided to safely wire the +12V, STATUS, IR IN and GND to the rear of a  
compatible keypad or touch-panel. This might be useful when adding an external IR Receiver or adding  
a sub-zone keypad either outdoors or in a bathroom (such as the WaterPad).  
Note: The 12VDC output terminal is rated at 100mA and can power up to one SmartPad/WaterPad or  
up to 4 IR Receivers. Any more then this will require the use of an external power supply. Do not wire  
the external power supply to the MX88 keypad. Wire directly to the units to be powered.  
The STATUS line is an output and is active High (+12VDC) when the MX88 Keypad is powered on and  
is Low (0VDC) when the Keypad is off. Use this to provide Bank Tracking LED on the SmartPad,  
WaterPad or another compatible device.  
In Zone IR  
To wire local emitters in-the-zone (emitters used to control components in the same general area as the  
keypad), wire the IR OUT and GND terminals on the rear of the keypad or touch-panel to the IR (white  
stripe) and GND of the emitter cable. To control numerous components in the same area, wire these  
terminals to an amplified connecting block (such as Xantech 791-44) using 18-20AWG 2-conductor  
cable.  
ZONE EXPANSION (CONNECTING TWO MX88 CONTROLLERS)  
For systems greater than 8 Zones, two MX88 Controller/Amplifiers can be linked together for systems up to 16  
Zones.  
LINKING TWO MX88 CONTROLLER/AMPLIFIER UNITS  
To connect two systems, simply connect the supplied DB15 Expansion Cable to Port 1 on the rear of one unit to  
the Port 2 on the other Figure 3 item 30. Either and both of the Port 2‟s can be used for source/device  
control, with our without RS2321x8 router.  
CONNECTING SOURCE COMPONENTS  
When connecting two units together, designate one unit as the PRIMARY Unit (Zones 1-8) and the other unit as  
the SECONDARY Unit (Zones 9-16). All source components should be connected directly to the PRIMARY  
Units Source A/V Inputs Figure 3 item 22. Use the PRIMARY Units Audio and Video Loop-Thru connectors  
Figure 3 item 23 to feed the source component inputs of the SECONDARY Unit Figure 3 item 22.  
All of the source components emitters should be connected to the PRIMARY Units IR Emitter Output Ports –  
Figure 3 item 26. This rule applies to the Sense Inputs also.

CONNECTING KEYPADS OR TOUCH-PANELS:  
-
-
-
While we use the term CAT5 throughout this manual, CAT5/5e/6/7 may be used to connect the MX88  
to Xantech keypads and touch-panels. Bear in mind that cable quality may reduce maximum lengths  
quoted throughout this manual or in the keypad or touch-panel manuals.  
The maximum cable length for CAT5 connections to a single keypad and/or multiple keypads varies  
depending on the keypad being used. In certain applications, external power supplies and/or the  
MRC44CB1 connecting block may be needed.  
Most Xantech touch-panels require an external power supply. In such cases the length of CAT5 will not  
be limited due to power requirements of the touch-panel, but by the maximum length allowed by the  
MX88 keypad interface bus. When using self-powered zone controllers only in a zone, the maximum  
CAT5 length from MX88 to the last controller should be 500ft or less.  
-
If any keypad in the zone is using an external IR receiver, or if an outdoor keypad (such as WaterPad)  
or an IR-onloy keypad (such as a SmartPad) is necessary in a sub-zone, the 4-pin EXTERNAL IR  
SENSOR CONNECTING BLOCK on the back of Xantech keypads and touch-panels can be used to  
power this IR device. The Maximum cable run to the external IR receiver/keypad in each of the above  
cases can be up to 125 feet from the keypad depending upon type and gauge of wire used.  
-
-
MRC88KP and MRC88DJKP keypads are older, legacy products that will work with the MX88, but  
cannot be mixed with MRKP1/MRKP1E/MRKP2/MRKP2E or the Xantech touchpanels within the same  
zone, due to using a different communications protocol.  
If no MX88-compatible wired keypads or touch-panels are used in a particular zone, IR Receivers  
and/or IR based Keypads may be used as shown in Figure 6 below, using the MRC44CB1 Connecting  
Block. This set up works for:  
1. Zones with IR Receiver ONLY  
2. Zones where a WaterPad, SmartPad, and/or IR Receiver is used  
FIGURE 5  
Using a CAT5 wire, connect one end into the desired Zone output of the MX88 controller and connect the  
other end to the RJ45 connector labeled CONTROLLER on the MRC44CB1 connecting block. IR Receivers  
terminated with a Stereo Mini Jack can be directly connected to the MRC44CB1 connector labeled IR IN.  
For all others IR Receivers with bare wire or the IR keypads, use 24AWG or larger cable and connect using  
the +12V, GND, and SIG screw terminals. A separate power supply is required for configurations in which  
the current load will approach 100mA. In fact, we recommend that an AC Adaptor/Power Supply is always  
used whenever possible. Consult the MRC44CB1 manual for complete instructions.

Appendix  
RS232 CONTROL  
This document describes the bi-directional RS232 interface of the MX88 using the two COM PORTs on the rear  
of the system (Fig. 3 item 29). This interface allows an external RS232 device to control the MX88 via a set of  
ASCII text commands. It is also possible to control any IR device connected to the MX88 system as well by  
triggering individual IR Commands and/or IR Macros via ASCII strings.  
TYPES OF COMMANDS  
There are two types of information that can be sent to the MX88 Controller: COMMANDS and QUERIES.  
COMMANDS are ASCII strings used to set a specific parameter in the system (i.e. Select a Source, turn a zone  
ON, start a DVD player etc…). QUERIES are requests for system status information and result in the MX88  
controller sending back a reply to the string being sent (i.e. seeing what zones are on, which sources are  
selected and volume settings etc….)  
INTERFACING TO THE RS232 COM PORTs  
The RS232 Com Ports on the rear of the MX88 Controller, when used with the included DB15-DB9 adaptors,  
are wired as a null modem‟ end, meaning the Transmit and Receive line have already been interchanged for  
direct communication with a PC. What this means is when connecting to a standard PC‟s Com Port, no Null  
Modem cable is necessary.  
The pin out configuration for this connector is:

ASCII STRING „INITIATING‟ AND „TERMINATING‟ CHARACTERS  
The parsing of incoming data on the COM PORT can be disabled via a setting in the Universal Dragon project.  
This might be necessary if the COM port is to be used to control an external device and any incoming data from  
that device is to be ignored. This setting can be found with the settings for configuring the COM port.  
For the MX88 system to recognize incoming ASCII command strings, the string must begin with an „!‟ and for  
data queries the string must begin with a „?‟. All strings must end with a „+‟. This way it can determine the  
beginning and end of the string for processing.  
When a proper command is sent, an ASCII acknowledgement string of OK is returned to the issuing device. If  
an unrecognizable string is received, an ASCII string of ERROR is returned to the issuing device.

TROUBLESHOOTING  
If you encounter problems, review each of the following items and take corrective action as described. If  
problems persist, contact Xantech Technical Support.  
PROBLEM  
PROBABLE CAUSE AND SOLUTION  
The MX88, after a successful Transfer from Universal  
Dragon, will not send out any IR commands.  
a) Open all palettes that you used for the project.  
Click Edit Palette, on the first palette. When  
Palette Editor opens, retest each IR command to  
see that they operate the controlled equipment.  
b) Close the Palette Editor and click Edit Palette on  
the next palette. Repeat this procedure for each  
palette.  
A corrupted or incorrectly learned IR code has been  
transferred to the keypad.  
c) When you find the defective command "re-teach"  
it again using the Learning IR Commands  
procedure.  
d) Before going further, test the relearned command  
to see that it operates the controlled equipment.  
e) In the Palette Editor, right click the defective  
command on the right and delete it from the  
associated palette.  
f) Place the corrected command in the palette using  
the Add >> function.  
g) Close the Palette Editor and open the palette.  
h) Click the button on the virtual keypad that has the  
bad command and remove the command with a  
right click.  
i) Place the corrected command on the keypad  
button by clicking it on the palette.  
j) Redo the Transfer procedure.  
CAUTION: Always test all commands before  
transferring to the MX88!  
I have made hardware connections as shown in Figure 6 Try the following in the order listed:  
or 7. However, when attempting to learn IR commands,  
the "Waiting for IR from your Remote" display times out  
with the "No IR Recorded" dialog box.  
a) The default serial port selection (1) in Dragon  
Drop may already be in use by another device in  
your computer system (such as a mouse). Refer  
to SERIAL PORT SELECTION, page 36, and  
perform the procedure listed there and in the  
following section VERIFYING COM PORT  
COMMUNICATION.  
Your computer is not recognizing or finding the serial port  
connection to the MX88.  
b) Check and replace, if necessary, the connecting  
cables and the DB9-to-DB25 adaptor.  
c)  
The serial COM port settings, such as port  
addressing and IRQ parameters, may not be set  
correctly in Windows.

Model MX88  
PROBLEM  
PROBABLE CAUSE AND SOLUTION  
Unit will not learn IR commands from certain brands and  
models of remotes.  
a) Because of the wide variety of IR coding and  
timing relationships (there are no industry  
standards), there are some IR commands that are  
not learnable by the Dragon Drop-IR™.  
Be sure to test all components first to see that  
their IR command codes are learnable by Dragon  
Drop-IR and are executable by the MX88 before  
selecting final components for the system.  
To aid you in this selection, see CAUTION card  
included with these instructions for the latest  
information relating to code compatibility.  
NOTE: Certain IR commands that are not  
normally learnable, or those that operate more  
correctly when learned with special techniques at  
Xantech, are available on the CD ROM that  
comes with Dragon. These, and the most recent  
updates to these files, are available on the  
Technical Support for details.  
b) Components using IR carriers higher than 71 kHz  
cannot be learned directly. Most are learnable,  
however, when down-converted by Xantech  
products such as the 291P, PMS12, 291-455,  
MS455, etc. Refer to the Xantech Product  
Catalog and contact Technical Support for details.  
Be sure you have the Make and Model number of  
the component and its remote before contacting  
Technical Support.  
"Record ERROR, try again" shows on screen while  
learning IR commands or “No IR Recorded” message is  
displayed.  
Do the following:  
a) Repeat the Learning procedures.  
You may have to experiment with the distance the  
remote is held away from the IR SENSOR on the  
front of the MX88. For most cases it will need to  
be within one inch of the Learning eye.  
b) Vary the amount of time you hold down the  
"teaching" remote's buttons. Most of the time only  
a brief tap is necessary.  
c) Be sure there are no sources of strong IR  
interference near the MX88 (such as CFL lamps,  
TVs, Your Computer Monitor, Neon lighting, etc.).  
Shade or move the location of the MX88 as  
necessary.  
Sometimes the command "takes" but does not operate  
the device.  
This may occur if you hold the "teaching" remote too far  
away, too close, or at too great an angle to the front of  
the MX88, or, IR interference is present.  
Also, with some remotes, you may be holding down the  
buttons for too long or too short a period of time when  
"teaching" the commands.

PROBLEM  
PROBABLE CAUSE AND SOLUTION  
When Transferring the project to a MX88, the transfer  
stops with a "Transfer aborted-Receiver Stopped  
Responding" or a "Communications Error---" message.  
The following items may have interfered with the  
transfer of data. Check each one in the order listed,  
then redo the transfer.  
a) Click on Preferences under the FILE menu and  
verify proper Com Port is selected  
b) Make sure no other software is running that also  
requires the Com Port  
c) Conduct a “Base Unit – Who Am I” to verify proper  
communication with the MX88.  
d) Check the COM PORT interface cable for  
continuity on each of its 9 leads. This is a Pin to  
Pin, 1:1 configuration. Replace if necessary.  
e) Your computer may have run out of system  
resources (memory). Quit other open applications  
and restart Windows with the MX88 connect to the  
PC  
.
After transferring commands to the MX88, it works fine ... IR noise may be on the IR bus-line coming from an IR

commands at all.  
receiver in another room or rooms, preventing a clean  
IR signal from arriving at the controlled component.  
a) Temporarily disconnect each MX88 Keypad one  
at a time, until you find the one causing the  
interference.  
b) Look for sources of IR interference near the IR  
receiver(s) [such as PLASMA, CFL lamps, TVs,  
Neon lighting, etc.]. Move or shade the IR  
receiver(s) or take other steps as necessary.  
The STATUS LED under the POWER button on the  
Keypad is never illuminated GREEN or flickers  
constantly.  
Again. IR noise is probably the problem. Adjust the  
Input Sensitivity of the IR Receiver might be to  
sensitive. Back off (turn CCW) on the IR Sensitivity  
Adj. on the rear of the keypad until the GRENN LED  
comes on steady. If a PLASMA is nearby, you might  
need to disable the Keypad IR Receiver and add a  
Plasma Friendly unit to the system.

Model MX88  
PROBLEM  
PROBABLE CAUSE AND SOLUTION  
Problems Controlling the MX88 via the RS232 port on  
the rear of the system.  
1. Check the cabling between the controlling unit  
and the MX88.  
2. Verify proper command is being sent to the  
MX88. Refer to Appendix A and section on  
RS232 Translator for recognized ASCII  
commands.  
3. Verify RS232 Port settings are set properly for  
both devices (i.e. Baud Rate, Data Bits, Stop  
Bit etc..)  
4. Verify pin out from controlling device and the  
MX88 to be sure proper handshaking between  
the Tx and Rx lines exist.  
NOTE: Tx and Rx lines on the MX88 are reversed  
from a standard PC. This allows communication  
between the MX88 and a standard PC Com Port  
without a Null Modem cable.  
Problems controlling an External Device via the MX88  
rear Com Port  
1. Check the cabling between the controlling unit  
and the MX88.  
2. Verify RS232 Port settings are set properly for  
both devices (i.e. Baud Rate, Data Bits, Stop  
Bit etc..)  
3. Verify pin out from controlling device and the  
MX88 to be sure proper handshaking between  
the Tx and Rx lines exist.  
NOTE: Tx and Rx lines on the MX88 are  
reversed from a standard PC. This allows  
communication between the MX88 and a  
standard PC Com Port without a Null Modem  
cable.  
4. Verify the MX88 is sending the appropriate  
commands out of the rear RS232 Port. This  
can be done by connecting the rear RS232  
Port directly to a PC‟s Com Port running  
Hyperterminal. View the command in  
Hyperterminal to see if the exact commands is  
being output correctly.  
5. Check the manufactures manual for the  
correct ASCII/Hex commands.  
NOTE: Sometimes a Carriage Return (0D  
Hex) and even possibly a Line Feed (0A) is  
required as terminating characters.
