The RCP2-1000 RM and a Rack Mount SSPA are linked together through 2-wire  
twisted pair shielded cable (such as 24 AWG twisted pair telephone cable). The cable  
should be connected between port J5 "Serial Local" of the RCP2-1000 and port J5  
“Serial Local” of the SSPA, as shown in Figure 2-2. Figure 2-3 shows the complete top  
level wiring diagram.

Figure 2-2: Cable connections for RCP2-1000  
To achieve reliable communication over long distances an adequate line termination  
(120 ohm resistor between RS485+ and RS485- lines) must be provided on both ends  
of the cable. The link provides data exchange through RS485 half-duplex serial inter-  
face with 9600 Baud data rate.  
Data link is peer-to-peer only; connection of a secondary SSPA or RCP2-1000 RM unit  
is not possible. The RCP2-1000 RM is designed to provide remote control by using  
second generation of Paradise Datacom SSPA serial protocol only. In other words, the  
RCP2-1000 RM provides support only for later model SSPA units with serial numbers  
above 100,000. Earlier models of SSPAs, which utilize a different style of serial  
protocol, cannot be controlled by the RCP2-1000 RM.

In order to achieve successful operation of the RCP2-1000 RM, the SSPA must be  
configured with the following parameters: Baud Rate - 9600; Serial Interface - RS485;  
Network Address - any. See your SSPA manual for details. Maximum cable length is  
4000 feet (1.3 km).  
2.5.1 Serial Port, Main (J4)  
A DB9 female connector serves as primary remote control interface connector. This  
interface allows the user to connect a PC to the RCP unit in order to access its ad-  
vanced features as well as access a remote SSPA unit through its serial port. Interface  
is re-configurable through the front panel menu, and can be used as RS-232 or RS-  
485 interface (2 or 4 wires). The RS-485 TX and RX pairs must be twisted for maxi-  
mum transmission distance. A user configurable 120-Ohm termination resistor is pro-  
vided on the same connector. Table 2-1 shows the main serial port pin-out.

Section 3: RCP2-1000 RM Front Panel Operation  
3.0 Introduction  
Control of the RCP2-1000 RM can be handled through Front Panel operation, or  
remotely through Parallel or Serial communication to a computer.  
For Local (front panel) operation of the controller, simply toggle the Local/Remote but-  
ton until the yellow LED indicator is illuminated on Local. When in Remote mode, the  
front panel buttons will be inoperative. The indicators and LCD display will still show  
the status of the system. The Local/Remote key is always operative so that the appro-  
priate mode can be selected. Remote operation enables the serial communication and  
parallel I/O control.  
3.1 RCP2-1000 Front Panel Description  
The RCP2-1000 front panel includes ten (10) LEDs to indicate the internal state of the  
SSPA. Five (5) fault condition LEDs on left side of the front panel reflect some of the  
SSPA major faults plus summary fault state. SSPA online LED will turn green when  
SSPA is in Online mode (1:1 Mode) or serves as AC power indicator in standalone  
mode. Local/Remote and Mute/Unmute LEDs show the current control mode and mute  
state of the SSPA.  
A diagram of the Front Panel is shown in Figure 3-1.

3.1.4 Liquid Crystal Display  
The 40 character by 2 line front panel liquid crystal display (LCD) provides a conven-  
ient method of selecting various operating parameters of the controller. All internal set-  
tings can be achieved via the LCD and menu structure. There is no need to access the  
interior of the controller to adjust or reconfigure hardware settings. The LCD also pro-  
vides detailed information on fault conditions.  
3.1.5 Main Menu Key  
The main menu key is a convenient method for instantly returning to the LCD main  
menu. No matter what menu screen is currently displayed on the LCD, pressing this  
key returns the user to the main menu, eliminating the need to scroll backward through  
several menu levels. See Section 3.2 for a complete description of the Main Menu.  
3.1.6 Local / Remote Key  
The Local/Remote key allows the user to disable or enable the local control keypad  
console. If the SSPA is in "Remote Only" mode, the unit will not react to any key-

Section 4: Theory of Operation  
4.0 Introduction  
The RCP2-1000 RM was designed to provide easy Remote Monitor and Control for the  
Paradise Datacom Rack Mount Solid State Power Amplifier (SSPA). The unit is  
designed to fit a standard 1 rack unit high, 19'' wide EIA rack. The RCP2-1000 allows  
the user to remotely access the Rack Mount SSPA to verify its internal conditions and  
provide necessary adjustments.  
4.1 Fault analysis and condition tracking  
RCP2-1000 RM provides detection and display of the Rack Mount SSPA as well as  
provides ability of tracking faults locally. RCP2-1000 RM outputs the following SSPA  
faults: Low Regulator Voltage Fault, High Temperature Fault, Low DC Current Fault,  
Auxiliary Fault, RF Switch, BUC fault (if applied) and Summary fault. Faults that are  
local to the RCP2-1000 RM unit (not implemented on the SSPA itself) provide  
additional control over remote interface: Low RF Fault, Power Supply Fault.  
RCP2-1000 RM also provides monitoring of the various internal conditions of the  
remote SSPA. These include: Base plate temperature, Power supply output voltage,  
SSPA DC Current consumption, Regulator output voltage, RF Output level, Gate Drive  
Voltage, Muting, Attenuation and internal redundancy control (if applied).  
As an addition, some popular features are provided on the RCP2-1000 RM such as  
audible alarm and fault latching. Fault output varies and is provided in different forms:  
relay contact closure, front panel LED and (or) LCD indication Serial data protocol field.  
4.1.1 Summary Fault  
Fault reflects overall state of the remote SSPA. Only "major" faults affect the summary  
fault state. Some faults may or may not affect the summary fault depending on the re-  
mote SSPA settings as well as RCP2-1000 RM settings. Fault state signaling: Front  
Panel LED; Front Panel LCD; Serial Protocol Field, Form C contact closure.  
4.1.2 Power Supply Fault  
Major fault. Fault implemented on the RCP2-1000 RM only. Remote SSPA won't track  
this condition. Fault effective, if SSPA internal power supply has output voltage lower  
then 10 volts. The fault threshold value is factory fixed and can't be changed by the  
user. Fault state signaling: Front Panel LED; Front Panel LCD; Serial Protocol Field,  
Form C contact closure.

4.1.3 Voltage Regulator Output Low Fault  
Fault effective when remote SSPA internal voltage regulators drop output voltage  
below 8 volts. Fault always retains its last state when SSPA is muted. Fault threshold  
value is factory fixed and can't be changed by the user. Fault state signaling: Front  
Panel LED; Front Panel LCD; Serial Protocol Field, Form C contact closure (in Stand-  
alone mode only).  
4.1.4 High Temperature Fault  
Fault is set when the remote SSPA's base plate reaches dangerously high tempera-  
tures. Fault state signaling: Front Panel LED; Front Panel LCD; Serial Protocol Field,  
Form C contact closure.  
4.1.5 Low DC Current Fault  
Major Fault. Fault is set when the remote SSPA indicates abnormally low current  
consumption. Fault always retains its last state when the SSPA is muted. Fault thresh-  
old value is factory fixed and can't be changed by the user. Fault state signaling: Front  
Panel LED; Front Panel LCD; Serial Protocol Field, Form C contact closure.  
4.1.6 Low Forward RF Fault  
Fault is local to the RCP2-1000 RM unit. Fault alerts the user when the output power  
falls below the threshold value. Threshold value is adjustable by the user with 1dBm  
steps. Fault handling is adjustable by user. Selection for fault handling: Alert Only  
(Minor Fault), Fault (Major Fault), Ignore (No Fault tracking) are available for user  
through front panel menu and remote control protocol. Fault state signaling: Front  
Panel LCD; Serial Protocol Field, Form C contact closure.  
4.1.7 BUC Fault  
Fault available only for Rack Mount SSPAs with the internal BUC option. In general a  
BUC fault is a major fault. Fault state signaling: Front Panel LCD; Serial Protocol Field,  
Form C relay contact closure.  
4.1.8 Auxiliary Fault  
User configurable fault. Fault condition occurs when HPA senses change of the state  
on external auxiliary fault input line. Fault effect depends from the costumer settings for  
this fault. Fault state signaling: Front Panel LCD; Serial Protocol Field, Form C contact  
closure (in Standalone mode only).

4.1.9 RF Switch Fault  
In Redundant mode, the SSPA always tracks position of RF switch(es). The user is  
informed about the RF switch state through the front panel LCD and serial protocol. If  
the switch position for any reason can't reliably be determined, the SSPA declares a  
RF switch fault state.  
4.1.10 Serial Connection Fault  
If serial communication can't be reliably established with remote SSPA unit, RCP2-  
1000 will declare Serial Connection fault condition. This condition set all major alarms  
and the summary state to the fault state. In addition, front panel LCD will display "No  
Connection!!" sign. The sign will automatically goes away if connection been success-  
fully reestablished. Of course, this condition won't prevent user from browsing through  
RCP2-1000 menus to observe last red parameters of the remote unit.

4.2 Design Philosophy  
The RCP2-1000 RM remote controller was designed to achieve a new level in high reli-  
ability, maintenance free operation. A tightly integrated modular assembly approach  
has been used to realize a versatile controller while maintaining its user friendly opera-  
tor interface. Four basic building blocks are combined in the unit:  
1. Digital Core Board  
2. I/O Board Assembly  
3. Liquid Crystal Display  
4. Front Panel Membrane Keypad  
Figure 4-1: Block Diagram, RCP2-1000 Digital Core Board  
4.2.1 Digital Core Board  
The Digital Core Board is the heart of the redundant controller. At the center of the  
digital core board is the Atmel AVR Mega 128 microcontroller. The microcontroller  
operates at a clock speed of 7.68 MHz. It provides control functions through the use of  
an 8 bit wide data bus and 16 bit addressing bus for most of the peripheral devices. A  
separate UART and collision detector is provided for extremely robust serial interfacing  
with multi-host networks. All digital I/O lines are protected by opto-coupling or transient  
absorbing devices. The power supply lines are protected by current limiting devices.  
30  
203987 Rev A RCP2-1000 RM Remote Controller Operations Manual  
Download from Www.Somanuals.com. All Manuals Search And Download.  
The digital core board also contains the interface circuitry that allows the RCP2-1000  
RM to be firmware upgradeable in the field. A block diagram of the Digital Core Board  
is shown in Figure 4-1.  
4.2.2 I/O Board Assembly  
The I/O Board Assembly contains the primary (hardware) interface circuitry of the con-  
troller. It is physically attached to the Digital Core Board by two 40-pin headers. The  
ten (10) Form C relays and opto isolated inputs for the parallel I/O interface are in-  
cluded on this board assembly. The board also provides a physical connection be-  
tween the liquid crystal display (LCD), front panel membrane keypad, and the Digital  
Core Board.  
4.2.3 Liquid Crystal Display  
The RCP2-1000 RM provides a large 2 line by 40 character alphanumeric display. This  
provides an extremely user friendly interface. The LCD is directly interfaced to the mi-  
crocontroller via the address and data bus. Virtually all of the controller’s setup and ad-  
justments are accessible from the LCD display. There is no need to access the interior  
of the controller to make any setup changes.  
4.2.4 Front Panel Membrane Keypad  
The front panel membrane keypad is a densely integrated array of LEDs and switches  
that comprise an important part of the user friendly interface. A great deal of human  
engineering has gone into the design of this membrane panel. A full complement of  
alarm indicators are provided along with the display. Four separate navigation buttons  
along with a separate “Enter” button allow the user to easily navigate the firmware  
menu on the Liquid Crystal Display. Separate buttons have been provided for fre-  
quently used functions further enhancing the controller’s ease of use.

Section 5: Serial Protocol  
5.0 Overview  
A system, which includes an RCP2-1000 and Rack Mount SSPA, can be managed  
from a remote computer over serial interface. To achieve this, the RCP2-1000 utilizes  
the same serial protocol as the Rack Mount SSPA with some minor exceptions.  
Requested parameter changes will not be reflected instantly on the RCP2-1000 unit  
because the RCP2-1000 is not a final target for the parameter changes.  
Some parameters are read only (all parameters under conditions tag). In other words,  
Paradise Datacom Universal M&C utilities for Windows will seamlessly incorporate  
RCP2-1000 in its control setup.  
In case of selecting Terminal mode protocol, the RCP2-1000 provides remote menu  
access through HyperTerminal program or actual hardware terminal.  
Serial protocol format is set at no parity, 8 bit with 1 stop bit. Baud rate is selectable  
through the front panel.  
5.1 Remote Control - Serial Communication  
This section describes the basic serial communication protocol between the SSPA and  
host computer. The amplifier will only respond to properly formatted protocol packets.  
The basic communication packet is shown in Figure 5-1. It consists of a Header, Data  
and Trailer sub-packet.

5.1.1 Header Packet  
The Header packet is divided into 3 sub-packets which are the Frame Sync, Destina-  
tion Address and Source Address packets (See Figure 5-2).

Figure 5-2: Header Packet  
5.1.1.1 Frame Sync Word  
The Frame Sync word is a two byte field that marks the beginning of a packet. This  
value is always 0xAA55. This field provides a means of designating a specific amplifier  
packet from others that may exist on the same network. It also provides a mechanism  
for a node to synchronize to a known point of transmission.  
5.1.1.2 Destination Address  
The destination address field specifies the node for which the packet is intended. It  
may be an individual or broadcast address. The broadcast address is 0xFF. This is  
used when a packet of information is intended for several nodes on the network. The  
broadcast address can be used in a single device connection when the host needs to  
determine the address of the amplifier. The amplifier will reply with its unique address.  
5.1.1.3 Source Address  
The source address specifies the address of the node that is sending the packet. All  
unique addresses, except the broadcast address, are equal and can be assigned to  
individual units. The host computer must also have a unique network address.

5.1.2 Data Packet  
The data sub-packet is comprised of 6 to 32 bytes of information. It is further divided  
into seven (7) fields as shown in Figure 5-3. The first six (6) fields comprise the com-  
mand preamble while the last field is the actual data.

5.1.2.1 Protocol ID  
This field provides backward compatibility with older generation equipment protocol. It  
should normally be set to zero. This field allows the amplifier to auto-detect other firm-  
ware versions.  
5.1.2.2 Request ID  
This is an application specific field. The amplifier will echo this byte back in the re-  
sponse frame without change. This byte serves as a request tracking feature.  
5.1.2.3 Command  
This one byte field tells the receiver how to use the attached data. There are only four  
(4) possible values for this field. The sender and receiver are limited to two commands.  
For example: if the sender issued “Set Request” command, receiver must answer with  
“Get Request” and “Get Response” form of the command. The byte value for each  
command is given in Table 5-1.

5.1.2.4 Data Tag  
The data tag specifies the type of internal resource of information needed to be ac-  
cessed on the amplifier. The data associated with certain tags is read only. Therefore,  
only the “Get” command byte would be associated with these data tags. The data tag  
byte values are given in Table 5-2.

5.1.2.5 Error Status / Data Address  
This byte is a tag extension byte and specifies the first data element of the tagged  
data. If the Data Length is more than 1 byte, then all subsequent data fields must be  
accessed starting from the specified address. For example, if the requester wants to  
access the amplifier’s unique network address, it should set data tag 0 (Systems set-  
tings tag) and data address 8 (see Systems Settings Details table). If the following  
Data Length field is more than one (1), then all subsequent Settings will be accessed  
after the Unique Network Address. When the Response Frame Data Address is omit-  
ted, this byte position is replaced with the Error Status fields. The various error codes  
are given in Table 5-3. Note that the Request and Response frames are different.

5.1.2.6 Data Length  
This byte contains different information for Request and Response frames. In a Re-  
quest frame, it specifies the number of data bytes that are to be accessed starting from  
the first byte of the value specified in the Data Address byte. That byte must not ex-  
ceed the maximum data bytes from a particular tag. The maximum data length for the  
Settings tag is 26 bytes. The maximum data length for the System Threshold tag is six  
(6) bytes.  
5.1.2.7 Data Field  
The actual data contained in the packet must be placed in this field. The “Get Request”  
type of command must not contain any Data Field. Any “Get Request” will be rejected if  
any data is present in the Data Field. Generally, the Bad Checksum error code will be  
added to the response from the amplifier if the word size of the information is 16-bits or  
2-bytes. Each data word is placed in the frame with its least significant byte first. All  
data with length of 2 bytes must be represented as integer type with maximum value  
range from 32767 to (-32767).  
5.1.3 Trailer Packet  
The trailer component contains only one (1) byte called the Frame Check Sequence  
(See Figure 5-4).

5.1.3.1 Frame Check  
The Frame Check field provides a checksum during packet transmission. This value is  
computed as a function of the content of the destination address, source address and  
all Command Data Substructure bytes.  
In general, the sender formats a message frame, calculates the check sequence, ap-  
pends it to the frame, then transmits the packet. Upon receipt, the destination node re-  
calculates the check sequence and compares it to the check sequence embedded in  
the frame. If the check sequences are the same, the data was transmitted without er-  
ror. Otherwise an error has occurred and some form of recovery should take place. In  
this case, the amplifier will return a packet with the “Bad Checksum” error code set.  
Checksums are generated by summing the value of each byte in the packet while ig-  
noring any carry bits.  
A simple algorithm is given as:  
Chksum=0  
FOR byte_index=0 TO byte_index=packet_len-1  
Chksum=(chksum+BYTE[byte_index]) MOD 256  
NEXT byte_index  
5.1.4 Timing issues  
There is no maximum specification on the inter-character spacing in messages. Bytes  
in messages to amplifier units may be spaced as far apart as you wish. The amplifier  
will respond as soon as it has collected enough bytes to determine the message. Gen-  
erally, there will be no spacing between characters in replies generated by unites. The  
maximum length of the packet sent to the amplifier node should not exceed 64 bytes,  
including checksum and frame sync bytes. Inter-message spacing must be provided  
for good data transmission. The minimum spacing should be as long as the time re-  
quired for transmitting five (5) bytes at the current baud rate. This time is required for  
the controller to detect a “Line Cleared” condition with half duplex communications.

Section 6: Terminal Mode  
The Paradise Datacom RCP2-1000 utilizes Terminal Mode Serial Protocol (TMSP) as  
a secondary serial protocol for Management and Control through a Remote Serial In-  
terface.  
TMSP allows the user to access internal SSPA functions via a remote ASCII Terminal  
or its equivalent (such as HyperTerminal for Windows). TMSP is accomplished through  
either the RS-232 or RS-485, half duplex, serial communication link.  
US ASCII encoded character strings are used to represent commands and data  
messages. A remote terminal or controller initiates a communication session and the  
RCP2 takes action and returns a report of requested status. The RCP2 will not initiate  
communication and will transmit data only when commanded to do so. Prior to estab-  
lishing the session with the RCP2, this mode must be enabled through the main menu.  
The remote terminal must be configured with serial settings that match the RCP2’s  
serial port settings. For example, if the RCP2 is set at 9600 Baud, the remote terminal  
must be also configured as ASCII terminal at 9600 Baud, no parity, 8 bit data with  
1 stop bit serial connection. The SSPA will not echo back any incoming characters, so  
local echo must be enabled on the remote terminal.  
To establish a remote control session with the RCP2, the user must type “UNIT#XXX”  
in the terminal window (all letters must be in upper case), where XXX is the RCP2’s  
unique network address or the global call address (255). Press the "Enter" key on  
Remote Terminal keyboard.  
The RCP2 should answer with words "Unit#XXX OnLine" with the first menu screen on  
the following lines. After a remote session is successfully established, the unit will stay  
connected as long as needed. The session interface mimics the RCP2's front panel  
menu. To help the user navigate through the menu, the help string with the list of  
active keys always follows the menu strings.  
For example:  
"Active Keys:(U)p+Enter;(D)own+Enter;(C)lrearFlt; (M)enu+Enter; (E)nd+Enter"  
will be the last transmission string on all informative menu screens. Note that all letters  
must be typed in upper case!  
To refresh current screen on the Remote Terminal simply press "Enter" key. To end a  
session with RM SSPA, press "E" and then "Enter" keys.  
Important! If multiple SSPA units are networked on the same serial link, DO NOT  
ESTABLISH A SESSION WITH MORE THAN ONE SSPA AT THE SAME TIME. If  
you do so you will not get a valid response from the SSPA!

The following procedure will guide the user through the remote terminal setup, using  
the Windows 95/98 HyperTerminal software. The RCP2 must be connected to a PC  
com port and configured to use TMSP with 9600 Baud rate prior to setting up the PC  
configurations.  
Start the Windows HyperTerminal Program (default Windows location at Pro-  
grams — Accessories — HyperTerminal).  
Enter the name of your serial connection (“Compact Outdoor SSPA” for ex-  
ample), and then click “Ok” button. See Figure 6-1.  
Figure 6-1: Connection Description window  
Select direct connection to the PC communication port (Com1 for example),  
which meant to be used for communication with SSPA unit, and then click  
“OK” Button. See Figure 6-2.

In the next window, select the following as shown in Figure 6-3: Bits per  
Second: 9600; Data bits: 8; Parity: None; Stop bits: 1; Flow control: none.  
Click “OK”.  
Figure 6-3: COM3 Properties window  
Normally, the SSPA will not echo back characters typed by the user in  
Terminal window. For added security and convenience, turn on Local Echo  
in the HyperTerminal application. To do so, select the following from the  
HyperTerminal menu: File -> Properties -> Settings -> ASCII setup. This will  
bring up a window similar to that shown in Figure 37. In this window, check  
the box marked “Echo typed characters locally” and click “OK”.  
Note: Due to a software bug on some versions, this feature may not work.

Your PC is now configured to work with the RCP2 in Terminal mode. To es-  
tablish a session with the RCP2, type “UNIT#170”  
Note: When using a RS485 connection, avoid using the global address (170).  
Instead, use the unique RCP2 address.

The RCP2-1000-RM includes two serial communications ports (J4 and J5). The Main Serial  
Port (J4) allows remote communication with a personal computer. The Local Serial Port (J5)  
allows a serial interface with a remote Rack Mount SSPA. Interface parameters are set by in-  
ternal RCP hardware and cannot be reconfigured by user.  
In addition, the RCP2-1000-RM features a 37-pin Parallel I/O port that contains a series of  
contact closures for monitoring remote SSPA faults as well as opto-isolated inputs for control-  
ling some of the SSPA functions. Inputs react on the closure to ground.
