RF Exposure Warning
Exposure to radio frequency (RF) energy has been identied as a potential environmental factor that must be considered before
a radio transmitter can be authorized or licensed. The FCC and IC have therefore developed maximum permissible exposure
(MPE) limits for eld strength and power density, listed in FCC 47 CFR § 1.1310 and IC RSS-102 Issue 2 Sect 4. The FCC
has furthermore determined that determination of compliance with these exposure limits, and preparation of an Environmental
Assessment (EA) if the limits are exceeded, is necessary only for facilities, operations and transmitters that fall into certain risk
categories, listed in FCC 47 CFR § 1.1307 (b), Table 1. All other facilities, operations and transmitters are categorically excluded
from making such studies or preparing an EA, except as indicated in FCC 47 CFR §§ 1.1307 (c) and (d).
Revised FCC OET Bulletin 65 (Edition 97-01) and IC RSS-102 Issue 2 provide assistance in determining whether a proposed
or existing transmitting facility, operation or device complies with RF exposure limits. In accordance with OET Bulletin 65, FCC
47 CFR § 1.1307 (b) and RSS-102 Issue Sect 2.5, the Codan Radio Communications transmitter manufactured in Canada is
categorically excluded from routine evaluation or preparing an EA for RF emissions and this exclusion is sufcient basis for
assuming compliance with FCC/IC MPE limits. This exclusion is subject to the limits specied in FCC 47 CFR §§ 1.1307 (b),
1.1310 and IC RSS-102 Issue 2 Sect 4. Codan Radio Communications has no reason to believe that the excluded transmitter
encompasses exceptional characteristics that could cause non-compliance.
Notes:
The FCC and IC’s exposure guidelines constitute exposure limits, not emission limits. They are relevant to locations that •
are accessible to workers or members of the public. Such access can be restricted or controlled by appropriate means
(i.e., fences, warning signs and others).
The FCC and IC’s limits apply cumulatively to all sources of RF emissions affecting a given site. Sites exceeding these •
limits are subject to an EA and must provide test reports indicating compliance.
RF Safety Guidelines and Information
Base and Repeater radio transmitters are designed to generate and radiate RF energy by means of an external antenna, typically
mounted at a signicant height above ground to provide adequate signal coverage. To reduce potential radio interference to other
users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (EIRP) is not more than
that permitted for successful communication. The following antenna installation guidelines are extracted from Appendix A from
OET Bulletin 65 and must be adhered to in order to ensure RF exposure compliance:
Non-building-mounted Antennas:
Height above ground level to lowest point of antenna ≥ 10 m•
Power ≤ 1000 W ERP (1640 W EIRP)•
Building-mounted Antennas:
Power ≤ 1000 W ERP (1640 W EIRP)
The following RF Safety Guidelines should be observed when working in or around transmitter sites:
The minimum safe distance the user should be from the transmitter antenna while transmitting is 142 cm for •
transmitters 8W or less and 300 cm for ampliers 30W or less. This assumes a maximum antenna EIRP of 15 dBi.
Do not work on or around any transmitting antenna while RF power is applied.•
Before working on an antenna, disable the appropriate transmitter and ensure a “DO NOT USE” or similar sign is •
placed on or near the PTT or key-up control.
Assume all antennas are active unless specically indicated otherwise.•
Never operate a transmitter with the cover removed.•
Ensure all personnel entering a transmitter site have electromagnetic energy awareness training.•
For more information on RF energy exposure and compliance, please refer to the following:
FCC Code of Regulations; 47 CFR §§ 1.1307 and 1.1310•

GENERAL
INFORMATION
INTRODUCTION
The CP-SC-3 Synthesizer Channel Programmer
is a tool developed to permit bench and eld
programming of the MT-3 family of synthesized
radios. The CP-SC-3 Synthesizer Channel
Programmer is packaged in the same enclosure
as the MT-3 receiver module, thus allowing it
to be conveniently mounted in any receiver
subrack slot position. An interconnect cable
(Type F to DB-9) connects the front panel of
the CP-SC-3 Synthesizer Channel Programmer
to any free standing synthesized receiver or
transmitter.
The CP-SC-3 Synthesizer Channel Programmer
is designed to interface with all Codan MT-3
Repeater System of synthesized receivers and
transmitters. The main feature of the CP-SC-3
Synthesizer Channel Programmer is to permit
the user to program any of the 15 desired
channels and view all 16 channels.
NOTE: Channel 1 is set by the internal
binary coded decimal switches.

THEORY OF
OPERATION
CP-SC-3 PROGRAMMER
MAINBOARD
The CP-SC-3 Synthesizer Channel Programmer
Main PCB contains an M68HC11 E-series
microcontroller unit (MCU), an RS-232
transmitter / receiver IC, a +5 VDC regulator,
and digital multiplexers to control the data
communication paths.
The CP-SC-3 Synthesizer Channel Programmer
Main PCB requires a +9.5 VDC supply. The
current drawn from this supply varies from
typically 250 mA for the CP-SC-3 programmer
plus the current draw from the specic
synthesized RF module. An optional fuse for
the +9.5 VDC line can be used in cases where
external power is supplied other than from a
subrack (this requires a special 48-pin Type F
connector).
U1 and Q1 supply the +5 VDC regulated
circuitry. U2 is the RS-232 transmitter / receiver
for serial communication with a host terminal.
U5 and U6 are digital switches offering serial
communication data path control. U7 and diodes
CR1 through CR4 provide isolation (protection)
from the synthesized RF module connector (J2).
U3 is an under voltage sense IC that shuts down
U4 as a safety measure. U4 is the heart of the
CP-SC-3 Synthesizer Channel Programmer
and provides I/O, 256 bytes RAM, 2048 bytes
EEPROM, Serial Communication Interface and
Timer System control. JU8 allows U4 to be
powered up in bootstrap mode. U8 allows for the
initial burning of the EPROM.

Theory of Operation
4
Synthesizer Channel Programmer Instruction Manual
IM51-CPSC3-4-0-0
JU12 through JU14 allow the digital switches to
be controlled by the MCU or controlled manually.
Transistor Q2 controls the bootstrap line to the
synthesized RF module. J1 is a 38 conductor
ribbon cable connecting the front panel board
to the mainboard. J2 is a DB-9 connector for
interfacing to the synthesized RF module. J2
supplies power, serial communication and
bootstrap lines to the synthesized RF module.
J3 is a 48-pin Type F connector supplying +9.5
VDC regulated to the CP-SC-3 programmer
module. J4 is a Mini-8 DIN connector supplying
serial communication to a host terminal.
CP-SC-3 PROGRAMMER
FRONT PANEL BOARD
The CP-SC-3 Synthesizer Channel Programmer
front panel PCB contains two alphanumeric
displays and four user accessible push button
switches. All the power, push button switches,
address and data lines are routed via P1 to the
Main PCB.
All address lines, data lines, power lines and
control lines are routed to the two alphanumeric
displays and the four push button switches. P1
is a 38-conductor ribbon cable connecting the
front panel board to the mainboard.
CP-SC-3 PROGRAMMER
MODES OF OPERATION
The CP-SC-3 programmer operates in four
different modes.
Mode 1
Mode 1 is the user default mode.
Communication occurs between the CP-SC-3
programmer (single chip mode) and the
synthesized RF module (single chip mode).
Upon power up or RESET the CP-SC-3
programmer is placed in mode one, where it
displays the ashing message ‘Data wait’. In this
state the CP-SC-3 programmer sends out an
ASCII carriage return and waits for a prompt (‘>’)
from the synthesized RF module.
The synthesized RF module must be turned
on after the CP-SC-3 programmer is in the
‘Data wait’ state, otherwise communication
is not possible. The reason for this is that the
synthesized RF module serial receive line
is pulled low and is read at power up, so for
communication to take place the CP-SC-3
programmer must pull that line high before
the synthesized RF module is powered up. If
no prompt is received, another ASCII carriage
return is sent. This process is repeated every
second.
Once the prompt is received from the
synthesized RF module, the CP-SC-3
programmer sends a series of commands to
retrieve the memory locations of all sixteen
channels and stores them in internal RAM.
When all the data has been received, the display
will show Channel 1 and the current binary
coded decimal switch settings. It is here that
the user can view all channel locations and
determine the status of the synthesized RF
module (to nd out the operating frequency of
any channel the appropriate channel designation
table must be used). Any improper channel code
numbers will result in the RF module failure.
The user can now change any of the 15 memory
locations. After all the changes are completed,
the user simply presses the PRGM (program)
key and waits for the CP-SC-3 programmer
to nish programming (any improper channel
code numbers will result in the RF module
failure). Once the programming has nished, the
CP-SC-3 programmer retrieves the new data
and waits for a user key press. The CP-SC-3
programmer permits data retrieval from a fully
programmed synthesized RF module and allows
any number of synthesized RF modules to be
programmed with the same data.
Communication congurations are as follows:
Baud Rate: 9600
Data Bits: 8
Parity: None
Stop Bits: 1.0
Handshake: None
Duplex: Full

Theory of Operation 5
Synthesizer Channel Programmer Instruction Manual
IM51-CPSC3-4-0-0
Mode 2
Mode 2 is intended as a non-user mode.
To enter Mode 2, the FCTN key must be
continuously pressed for at least 2.5 seconds,
at which time the display will show ‘Mode 2’.
In this mode, communication between the
synthesized RF module (single chip mode) and
a host terminal is possible through application
programs such as ‘μASM-HC11’ or ‘White
Knight’. This mode allows retrieval of the
synthesized RF modules ‘Version data’ and
permits interactive communication with the
‘Menu commands’.
Communication congurations are as follows:
Baud Rate: 9600
Data Bits: 8
Parity: None
Stop Bits: 1.0
Handshake: None
Duplex: Full
NOTE: To return to Mode 1, press the
RESET key or the FCTN key for at
least 2.5 seconds.
Mode 3
Mode 3 is intended as a non-user mode.
To enter Mode 3, the FCTN key must be
continuously pressed for at least 2.5 seconds, at
which time the display will show ‘Mode 2’. The
ADV key must then be pressed once (the display
will show ‘Mode 3’). In this mode, communication
between the CP-SC-3 programmer (single chip
mode) and a host terminal is possible through
application programs such as ‘μASM-HC11’ or
‘White Knight’. This mode allows testing and
support of the CP-SC-3 programmer.
Communication congurations are as follows:
Baud Rate: 9600
Data Bits: 8
Parity: None
Stop Bits: 1.0
Handshake: None
Duplex: Full
Mode 4
Mode 4 is intended as a non-user mode.
To enter Mode 4, the FCTN key must be
continuously pressed for at least 2.5 seconds,
at which time the display will show ‘Mode 2’.
The ADV key must then be pressed twice
(the display will show ‘Mode 4’). In this mode,
communication between the synthesized RF
module (bootstrap mode) and a host terminal
is made possible through application programs
such as ‘LabVIEW’ or ‘PROG11’.

INSTALLATION
AND OPERATION
BASIC OPERATION
To aid in operation of the CP-SC-3 programmer,
the nomenclature in this manual differs slightly
from that of any synthesized RF module manual.
This manual refers to the memory locations
in a synthesized RF module as channels (i.e.,
Channels 2 through 16) and refers the value
programmed in a memory location as a four
character code number (referred to as Chan.
Num. in the Channel Designation Table of a
synthesized RF module manual).

Installation and Operation
8
Synthesizer Channel Programmer Instruction Manual
IM51-CPSC3-4-0-0
SETUP
Any SR-3 (with a System monitor) or SP-3 subrack will be required to power the CP-SC-3
Programmer.
1. Connect the Type F to DB-9 cable to the front panel TX/RX DATA I/O connector using the DB-9
connector end.
2. Install the CP-SC-3 Programmer into any MT-3 receiver slot in the subrack (SR-3 or PR-3).
3. Turn on the power to the CP-SC-3 programmer (apply power to the subrack).
After power-up or RESET, the display window indicates the status of the CP-SC-3 Programmer.
While the CP-SC-3 is waiting to receive data, the display will read ‘Data Wait’. In normal operation,
the channel number will be displayed above the corresponding code number.
4. Connect the synthesized RF module to the Type F to DB-9 cable using the Type-F connector
end.
NOTE: Any synthesized RF module requiring External Reference Input must have the External
Reference Input applied.
Transmitter module RF outputs can be active and should be properly terminated.
Always remove the CP-SC-3 programmer prior to subrack operation.

How To Choose The Right Code Number – Frequency
Channel Designation Tables can be found in the back of the appropriate synthesized RF module
Instruction Manual. The code number can be found by looking up the desired frequency—noting the
code number (Chan. Num.) located to the left—and programming this new value.
For example, a frequency of 133.82500 megahertz translating to code number (Chan. Num.) 1165,
can be programmed.
RF Module Duplicate Programming
The CP-SC-3 Synthesizer Channel Programmer permits data retrieval from a fully programmed
synthesized RF module and allows any number of synthesized RF modules to be programmed with
the same data. To do this, follow these steps:
1. Connect the fully programmed synthesized RF module.
2. Press RESET and wait for the new data.
The display will indicate Channel 1 and the four character code number for that channel.
3. Connect the new synthesized RF module.
4. Turn on its power (‘NORM’ for receivers or ‘KEY TX’ for transmitters).
5. Press PRGM.
NOTE: As long as the RESET is not pressed; or a code number is not changed; or power to
the CP-SC-3 programmer is not interrupted, the data for Channels 2 through 16 will be
retained.
6. Steps 3–5 can be repeated for as many times as required.
