High Voltage for the purpose of this section is any voltage in excess of 30 volts. Volt­ages above this value can be hazardous and even lethal under certain circumstances.
Care should be taken when working with devices that operate at high voltage.

• All probes and tools that contact the equipment should be properly insulated
to prevent the operator from coming into contact with the voltage.

• The work area should be secure and free from non-essential items.

• Operators should never work alone on high voltage devices. There should

always be another person present in the same work area to assist in the
event of an emergency.

• Operators should be familiar with procedures to employ in the event of an
emergency, i.e. remove all power, CPR, etc.

An AC powered unit will have 115 VAC or 230 VAC entering through the AC power
connector. Caution is required when working near this connector, the AC circuit
breaker, or the internal power supply.

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 inter­face 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.

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 but­ton 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 appro­priate 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.

22 203987 Rev A RCP2-1000 RM Remote Controller Operations Manual

If the HPA controller card can not reliably communicate with an SSPA module, that
module will be declared faulted. This type of fault will not affect the HPA overall
summary fault state, because the controller card has the ability to track RF module
faults independently.

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 re­mote 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.

RCP2-1000 RM Remote Controller Operations Manual 203987 Rev A 27

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 Stand­alone mode only).

4.1.4 High Temperature Fault

Fault is set when the remote SSPA's base plate reaches dangerously high tempera­tures. 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 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.

4.1.6 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).

28 203987 Rev A RCP2-1000 RM Remote Controller Operations Manual

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, RCP2­1000 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 success­fully reestablished. Of course, this condition won't prevent user from browsing through
RCP2-1000 menus to observe last red parameters of the remote unit.

RCP2-1000 RM Remote Controller Operations Manual 203987 Rev A 29

4.2 Design Philosophy

The RCP2-1000 RM remote controller was designed to achieve a new level in high reli­ability, maintenance free operation. A tightly integrated modular assembly approach
has been used to realize a versatile controller while maintaining its user friendly opera­tor 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

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 con­troller. 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 in­cluded on this board assembly. The board also provides a physical connection be­tween 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 mi­crocontroller via the address and data bus. Virtually all of the controller’s setup and ad­justments 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 fre­quently 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.

5.1.1.1 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 com­mand preamble while the last field is the actual data.

5.1.2.2 Request ID

This is an application specific field. The amplifier will echo this byte back in the re­sponse 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.

5.1.2.5 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 set­tings 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 omit­ted, 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 Re­quest 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 ex­ceed 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

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, ap­pends it to the frame, then transmits the packet. Upon receipt, the destination node re­calculates 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 er­ror. 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 ig­noring any carry bits.

A simple algorithm is given as:
Chksum=0

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. Gen­erally, 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 re­quired 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.

For more information, see the Paradise Datacom Solid State Power Amplifier 4RU
Chassis Operations Manual, document number 201627.

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 In­terface.

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 estab­lishing 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!

RCP2-1000 RM Remote Controller Operations Manual 203987 Rev A 39

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 Pro­grams — Accessories — HyperTerminal).

• Enter the name of your serial connection (“Compact Outdoor SSPA” for ex­ample), 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.

Figure 6-2: Connection window

• 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.
Do not use versions prior to 6.3. Download the latest version of Hyper­Terminal at http://www.hilgraeve.com.

Figure 6-4: ASCII Setup window

• Your PC is now configured to work with the RCP2 in Terminal mode. To es­tablish 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.

An example of a terminal mode session shown on Figure 6-5.

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 in­ternal 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 control­ling some of the SSPA functions. Inputs react on the closure to ground.

The following tables show the pin outs for the Main Serial Port (J4), Local Serial Port (J5) and
Parallel I/O Port (J7).
