NTI VEEMUX VIDEO MATRIX SWITCH

INTRODUCTION

The SM-nXm-15V-LCD (n = number of inputs (video sources), m = number of outputs (monitors)) video matrix switch (VEEMUX)

allows any of up to 32 video sources to output to any or all of up to sixteen (16) monitors. The configuration of the VEEMUX is

determined at time of order (i.e. 16x4, 8x16, etc.). The bandwidth of the SM-nXm-15V-LCD is 200MHz and video resolutions

through 1900 x1200 are supported with no degradation. The switch can be controlled with the Front Panel Keypad, RS232

interface, Ethernet, or an optional Infrared Remote.

The VEEMUX can be ordered in many sizes and with several control options. The base unit includes a user keypad, an RS232

port, and an Ethernet port to make up a complete system. The infrared option, purchased separately, allows for maximum user

satisfaction in each unique configuration.

Basic Operation

The VEEMUX allows any source to be connected to any destination at any time with no restrictions or limitations.

•

Video inputs accept any RGBHV, RGBS, or RGsB signal.

Video outputs are compatible with any RGBHV or RGBS monitor, regardless of input. (RGsB monitor requires

RGsB input)

Supported Web Browsers

Most modern web browsers should be supported. The following browsers have been tested:

•

Microsoft Internet Explorer 6.0 or higher

Netscape 7.0 or higher

Mozilla FireFox 0.9.2 or higher

Set your browser to always check if there is a newer version of the page than the version stored in cache. This action will ensure

that it will display the most up-to-date information.

Compatibilty

The SM-nXm-15V-LCD is made to support video inputs from VGA (15HD – H & V Sync) only.

Ordering Information

The SM-nXm-15V-LCD is built to a specific size ranging from 2, 4, 8, 12, or 16 monitors and 4 to 32 video sources. The “n” in the

part number represents the number of video sources. Select a switch built for 4, 8, 16, or 32 video sources. The “m” in the part

number represents the number of outputs (monitors). A switch built for 2, 4, 8, 12, or 16 monitors may be ordered. It is not

necessary to fully populate all of the connectors on the unit (ex. an SM-16x8 switch has the capability of supporting 16 video

sources and 8 monitors, but it will operate with only 14 video sources with 7 monitors connected.

1. Plug the VEEMUX into an AC power outlet.

2. Turn ON power to the VEEMUX.

3. Turn ON power to the video sources and monitors connected to the VEEMUX.

LED MATRIX

(not available on all models)

The LED Matrix is a grid of LEDs on the front panel of the VEEMUX. This grid is used to provide a visual indication of all

connections between video sources and destinations. To determine if an input (video source) is connected to an output (video

destination), follow the LEDs down and to the right (respectively) until they intersect. The illuminated LED at the point of

intersection indicates the input is connected to the output by the VEEMUX.

NTI VEEMUX VIDEO MATRIX SWITCH

CONTROL OPTIONS

The VEEMUX video matrix switch has four methods of control:

•

Front Panel LCD with Keypad

Directly via an RS232 Interface

Remotely via Ethernet (rack mount models only)

Infrared Remote (optional).

Every unit comes standard with the Front Panel LCD with Keypad, and RS232 built in. Rack mount models also include Ethernet

connection. If desired, the Infrared option must be requested at the time of the order. The Infrared option requires the purchase

of a separate remote control device (Infrared transmitter) as well as an Infrared receiver to be installed in the VEEMUX. No

software is involved (see Infrared Control on page 23). With the RS232 option, there are no external devices to be purchased.

NTI provides software commands as well as a test program to ensure the RS232 functions properly (see page 8 – RS232

Control).

Front Panel LCD with Keypad Control

The front panel LCD and keypad allow the user to monitor switch status and route any user to any video source on the switch.

When the unit is powered up, each monitor is automatically connected to the video source of its equal number (i.e. monitor 1 to

source 1, monitor 2 to source 2, monitor 3 to source 3, etc.). Along with the routing of the inputs (video sources) to the outputs

(monitors) the keypad and LCD allow the users to configure the RS-232 control interface. The keypad buttons perform the

following functions.

The following examples show various method of routing output 3 to input 5. Inputs and Outputs can be entered as a two digit

number or a one digit number followed by IN or ENTER.

Configurations that are saved into memory locations via

the keypad can be recalled via the web interface (page 16)

and vice versa.

Note: If the current switch configuration includes assigned Scan Mode dwell time values (pg. 8), to save the current

configuration be sure to assign a memory location to it. Otherwise, when the VEEMUX is powered OFF, all dwell time

values will be erased. Also, saving the configuration as memory location 0 will cause it to be the power-ON default

configuration.

NTI VEEMUX VIDEO MATRIX SWITCH

Scan Mode

Scan Mode causes an output port to automatically switch from one input port to the next consecutive input port after a specified

period of time (referred to as the dwell time). Port switching will continue indefinitely and no ports will be skipped, whether there

are video sources connected to them or not. If desired, the VEEMUX can be configured to skip the scanning of specific ports

using the RS232 Command Protocol (page 9) or Telnet (page 13).

Dwell time settings can be any value from 0 seconds (000) to 255 seconds. A setting of 000 seconds (the default setting)

disables Scan Mode for that output port. If Scan Mode is disabled for a specific port, then the video to that output will only

change as decided by the administrator.

To configure Scan Mode from the front panel LCD:

Press MENU, the following lines will be displayed:

Set Baud Rate

Set Unit Addr

Press MENU again, the following line will be displayed:

3) Set Scan Mode

Press 3 to select that menu item. The following request will be displayed:

Select Port

Select the output to be programmed using the numeric keys, then press ENTER. The display will show the current Dwell Time

value for that output and ask for a new value.

Current Time: 16

New Time:

Using the numeric keys, enter a value between 0 and 255 and press ENTER. Leading zeros are allowed (000) but the number

should not exceed 3 digits. The Scan Mode dwell setting value 0 will disable Scan Mode for that output port.

Scan Mode settings can also be configured through the RS232 Command Protocol (page 10), Telnet commands (page 13), or

through the Web Interface (page 18).

NOTE: Scan Mode configuration settings can only be saved if they are assigned a memory location via the Keypad

Control (page 7). Otherwise when the power is cycled to the VEEMUX, all Scan Mode settings will be erased.

TIP: If the Scan mode settings are stored as memory location 0, they will be loaded each time the VEEMUX is powered

ON.

RS232 Control

RS232 enables the VEEMUX to be remotely controlled via RS232. To control the VEEMUX via RS232 the user has three

options:

•

write a program that runs on a PC using the Command Protocol (page 9)

use the Matrix Switcher's Control Program (page 11) provided on the CD

use the SerTest program (page 11) provided on the CD

Remote Connection

The RS232 Interface is designed to control the switch via serial (RS232) daisy chain connection from any host computer or other

controller with an RS232 communications port. There is, however, a restriction that must be followed:

The pin outs for the DB-9 connector on the unit are as follows:

NTI VEEMUX VIDEO MATRIX SWITCH

On the DB-9 female connector, pins 4 (DSR) and 6 (DTR) are shorted and pins 7 (CTS) and 8 (RTS) are shorted. Therefore, host

handshaking is bypassed and TXD and RXD are the only active signals. A straight through DB-9 cable (not null modem) will work

for most CPUs. To daisy chain multiple units, use NTI Matrix-Y-1 "Y" cables, except for the last unit connected. (see Fig 6). For a

pinout of the Matrix-Y-1 cable, see page 32. For straight through cable pinouts applicable to various terminal types, see page

31.

Baud Rate

The unit powers up with a default baud rate of 9600 and a fixed data protocol of 8 data bits, no parity and 1 stop bit. The baud

rate can be changed by pressing the MENU button on the front panel keypad. Then select 1 for SET BAUD RATE and select the

desired baud rate of 9600, 2400, 1200 or 300. A data protocol of 8 data bits, no parity, and 1 stop bit is used for communications.

Unit Address

To allow multiple units to be controlled from a single CPU port, the RS232 control interface is designed to allow "daisy chaining"

up to 15 units using the NTI Matrix-Y-1 "Y" cables. By setting the appropriate unit address with the keypad (the default address is

01), each unit can be given a unique address (1-15). Then the unit will only respond to commands on the bus if its address is

embedded in the command.

Command Protocol

CPU controller commands supported by the unit are defined below. All commands should be terminated with a <CR> (carriage

return). When a command is sent, the entire string is echoed back along with a response from the addressed unit as shown in the

command definitions table below. All characters in the command string should be upper case, and all numbers below 10 should

have a leading 0 (ex: 1 = 01). As command strings are sent, the inner character delay cannot exceed 500 milliseconds.

Note: To use this command protocol, the user is required to write a program that will send an entire command string all

at once, not character by character. Programs that send one character at a time (such as HyperTerminal) cannot be used

to control the VEEMUX. Alternatively, the user may use the Matrix Switcher's Control Program or SerTest to control the

VEEMUX via RS232 (see page 11).

If the first field is not a known command (as listed above) or SW field is different from the serial address programmed in the switch

memory, the command will be ignored. If the SW field corresponds to the unit address, but the syntax is wrong after this field, the

switch will answer with a bad response ?<CR>.

Autostatus

When Autostatus is enabled, any output-to-input connection change in the VEEMUX will cause an Autostatus message to be sent

via RS232 to the administrator. The format of the message would be "pc SW,OP:IP<CR>"

Example of an Autostatus message:

pc 01,01:04<CR>

which means "At the switch with unit address 01, the output (01) has changed connection to input 04."

Notes: Message to the administrator will be delayed by any RS232 traffic being received by the switch from the

administrator.

Autostatus must be disabled before using SerTest or the Matrix Switcher's Control Program (below).

By default, Autostatus is disabled and must be manually enabled. Autostatus is also disabled any time the power to the

VEEMUX is interrupted.

INFRARED CONTROL

(Optional)

The IRT-64X32 (or IRT) is an infrared remote transmitter that enables the user to control up to four (4) NTI VEEMUX Video Matrix

switches via an infrared receiver from up to 50 feet away (with an unobstructed view). The IRT is battery-powered and always

ready to use. The IRT will have a blank display unless an action is being selected by the user. The IRT enables the user to

make connections between any input (video source) and any output (display device) on up to four (4) separate switches.

Note: Multiple switches that are located close to each other and are to be individually controlled must be pre-configured

(by NTI) to be identified by the IRT as switches #1, #2, #3, or #4. Please ask your salesperson to have switches

configured accordingly at time of order. Unless otherwise specified, by default, all IRT-enabled switches will be

configured as switch #1.

NTI VEEMUX VIDEO MATRIX SWITCH

How To Use The IRT

The IRT-64X32 enables the user to control the connections of up to 32 input ports and 16 output ports on up to four (4) separate

NTI video matrix switches. When any key is pressed, the IRT will power ON. A number key should always be pressed first

unless a change to the configuration is desired (see "Set Configuration" on page 24). When a number key is pressed the LCD

will display that number blinking. What to press next depends on what action is desired;

•

change the input port

Note: The user must always change or confirm the output port first and the input port second

If the "SYS", "IN" or "OUT" key is pressed first, the LCD will display the current switch followed by the decimal point and an error

signal "EE". The error signal will display because there is no number to be displayed. A number key must always be pressed

before a "SYS", "IN" or "OUT" key is pressed.

Exception: The "SYS" key is pressed first when setting the configuration. (See page 26)

Power ON with SYS, IN or OUT keys

Power ON with "2" key

Change the Switch

Press the number of the switch to be controlled. The number selected will be blinking in the last digit.

FYI: If the user realizes that an invalid number has been introduced before pressing either the "SYS", "IN", or "OUT"

buttons, a correction can be made by pressing the correct number. If the correct number is a single digit, it must be

preceded by a "0" to make the correction.

Press the "SYS" key. The blinking number will become blank and the switch number will update.

Note: If the number entered is larger than 4, when the "SYS" key is pressed the LCD will display the current switch and

the error signal "EE".

the "OUT" button again. The LED at the receiver will illuminate to indicate a completed transmission from the IRT..

Note: If the number introduced is larger than the maximum number of outputs the IRT is configured for, then once the

"OUT" key is pressed the LCD will display the current switch and the error signal "EE".

Change Input Port

Press the desired port number. As the digits are selected, the last number entered will blink. The LCD will also display the

current switch number followed by the decimal point.

With the desired port number selected, point the IRT at the switch/receiver and press the "IN" button to transmit the selection and

make the change. The blinking number in the LCD will stop blinking. The LED at the receiver will go OFF.

FYI: If the switch did not receive the data the LED will not go OFF. The user can re-send the same data by pressing the

"IN" button again. The illuminated LED on the receiver will go OFF when the received data is complete.

Note: If the number introduced is larger than the maximum number of inputs that the IRT is configured to control, then

once the "IN" key is pressed the LCD will display the current switch and the error signal "EE".

NTI VEEMUX VIDEO MATRIX SWITCH

Set Configuration

The IRT-64x32 factory default setting is 32 inputs and 16 outputs. When the batteries are changed the setting will return to the

default value. At the default setting the IRT has the ability control any matrix switch with up to 32 inputs and 16 outputs without

changing the configuration. However, when controlling smaller switches without changing the configuration it is up to the user to

press valid number(s). To avoid confusion, it is recommended to configure the IRT to communicate with the largest switch to be

controlled.

To change the maximum number of inputs or outputs:

1. From power-down state (blank LCD) press and hold the "SYS" button for at least 3 seconds. The LCD will first display an

error message but after 3 seconds the letter "c" will display:

2. Enter the number of inputs or outputs. As the digits are entered, they will be displayed and the last one entered will blink.

Note: Only the inputs OR the outputs may be configured each time the configuration function is used. To perform

another configuration operation the user must start again at "Set Configuration" step 1.

3. Accept the choice by pressing the "IN" button for setting inputs, or the "OUT" button for setting the outputs. The LCD will not

blink anymore and will display “i” (for inputs) or "o" (for outputs) and the number.

Notes:

The maximum number of inputs and outputs that can be entered is 32 and 16 respectively. If the user introduces a

number larger, the display will show an error signal ("c.EE") and the maximum number will remain at the last valid

value configured.

If more than one switch is being controlled, the IRT should be configured for the largest switch. It is up to the user

to introduce valid numbers to the smaller switches when making selections.

Battery Replacement

The IRT has a low-battery indicator to let the user know when it is time to change the batteries. The right-hand decimal point in

the LCD display will illuminate (see illustration below). This will stay illuminated while the IRT is in use until the batteries are

changed or the battery charge is too low for the IRT to operate.

To Change The Batteries:

1. Remove slide cover on rear of unit.

2. Remove old batteries carefully.

3. Insert (2) new “AA” cell batteries.

NTI VEEMUX VIDEO MATRIX SWITCH

DDC SUPPORT

(Optional)

DDC information allows the CPU to automatically select the optimal resolution for the monitor by receiving, at power up,

information from the monitor concerning its resolution specifications.

When DDC Support is installed, the DDC information is acquired from the monitor by the VEEMUX-A switch when the VEEMUX-A

is powered-up. A monitor with DDC support must be connected to MONITOR 1 for this to occur. The DDC information will

be made available at every CPU port.

The DDC information can also be acquired by pressing the DDC button located on the front of the switch. This button allows the

monitor configuration to be changed without powering down the switch.

Notes:

1. All monitors connected to the VEEMUX-A switch with DDC support must be able to support at least the maximum

resolution of the DDC monitor connected to '"MONITOR 1".

2. In order for the CPU to correctly receive the DDC information from the switch at boot-up, the switch must be

powered up before all attached CPUs.

RS232 UPGRADE OF THE FRONT PANEL LCD FIRMWARE

The firmware in the front panel LCD can be upgraded to include the latest features available using either the RS232 port

(below) or Ethernet Control (page 19). Follow the procedure below to use the RS232 method to update the Front Panel LCD

firmware in the VEEMUX. To prepare, first download the rmtlcd_va_1_x. hex file (x= the current firmware version) from

the NTI Video Matrix Switch website http://www.networktechinc.com/vmtx.html.

The following will be needed:

1 PC running HyperTerminal (or other terminal program) equipped with a 9 pin or 25 pin serial port

A VEEMUX made to use the Firmware Upgrade feature

1 serial cable wired straight through to connect your PC's serial port to the “RS232” port on the VEEMUX (see

cable specifications on page 31)

A firmware file for a VEEMUX downloaded from www.networktechinc.com

Procedure:

1. Power OFF the VEEMUX.

2. Connect the null modem cable between the serial port on the PC and the “RS232” port on the VEEMUX.

3. Use HyperTerminal to prepare to connect to the VEEMUX (using settings 9600 baud, 8-N-1 no flow). Make sure

HyperTerminal has been configured for connection through the correct COM port on the PC.

4. With the HyperTerminal window open, hold the spacebar and apply power to the VEEMUX. A command menu and the

Command prompt (>) should appear.

Flash Loader Utility v1.0

Command>

Note: Commands are not case-sensitive (for example, 'h' or 'H' will execute the help command), and the <Enter> key

is not required to execute a command.

If the Flash Loader Utility menu does not appear, the VEEMUX you have may have been made prior to the release of

this product change. To verify this, with the VEEMUX powered ON, at the HyperTerminal window enter the following

command:

RV 01 (be sure to include the space)

The following revision string will appear:

$date: 2006/04/17 20:20:59 $$revision: 1.1 $$IN: 08 $$OUT: 04 $

If the date shown is before 2006/04/17, then the VEEMUX firmware cannot be upgraded using this procedure.
