Chapter 1 - Introduction and Specifications
Congratulations on your purchase of the CAT-200B Repeater Controller. Programming the CAT-200B is a
snap, with its carefully structured uniform programming commands. The manual is easy to follow and
the voice synthesizer interacts with you during control and programming operation.
Voice Synthesizer
A vocabulary base of 335 words is available to ID your repeater and make voice announcements.
CW ID
The controller will switch to CW when a repeater user talks over the voice ID. When the voice ID,
message #1 is erased, the controller will ID in CW only.
Courtesy Tone
Separate courtesy tones denote repeater and link receiver activity.
Link Control
The CAT-200B will support a link transceiver. You can enable the transceiver or just the receiver to
monitor activity on the transceiver frequency while you use the repeater. The CAT-200B will suppress
your repeater identification from being transmitted on the transceiver frequency if Zone 2 Channel 5 is
disabled.
Weather Station Interface
Provide timely weather announcements on your repeater system. Connect a Peet Brothers Ultimeter ®
U-100, U-800 or U-2000 Weather Station to the serial port of the CAT-200B. Integrate temperature,
wind speed, direction and rainfall into any of the CAT-200B voice messages. Program a special weather
report message as part of your identification.
Beacon Mode
When the repeater is inactive and Zone 4 Channel 2 is enabled, the CAT-200B will key the transmitter
and announce voice message 7. This message will repeat at a rate determined by the Beacon timer.
User Function Output Switches
Four open collector user function output switches control equipment at your repeater site. These
switches are controlled manually by DTMF commands or from within a voice message. They can be
made to turn OFF, ON or Momentarily change state, any time you choose.
User Function Inputs
Four inputs activated by a voltage change from other equipment at the repeater site, causes the CAT-
200B to activate voice messages as alarms or announcements. The messages will continue to repeat as
long as the respective logic input remains active high. The logic input message timer controls the time
between announcements. Information about the repeater site will be instantly available.
DTMF Keypad Test
A DTMF keypad test will read back the numbers decoded in a synthesized voice.

Dip Switch
An eight-position dipswitch configures various functions of the CAT-200B.
NOTE: Anytime a dipswitch is changed, DC power must be cycled for the CAT-200B controller to read
the new setting.
Switch 1 This switch determines Repeater COR input logic. Switch #1 should be ON if the repeater
receiver's COR is an active low and OFF if COR is active high.
Switch 2 This switch determines Repeater CTCSS input logic. Switch #2 should be ON if the repeater
receiver's CTCSS is an active low and OFF if CTCSS is active high.
Switch 3 This switch determines Link COR input logic. This switch should be ON if the link receiver's
COR is an active low and OFF if COR is active high.
Switch 4 This switch determines Link CTCSS input logic. Switch #4 should be ON if the link receiver's
CTCSS is an active low and OFF if CTCSS is active high.
Switch 5 This switch determines if the CAT-200B is in the Repeater or Remote Transceiver Weather
Station mode. This switch should be OFF if the CAT-200B is configured as a repeater controller. If the
CAT-200B is configured as a remote weather station controller this switch should be ON. Consult
Chapter 12 for a description of the changes in operation.
Switch 6 This switch is used to identify that the CI-200 Interface module is connected to the CAT-200B.
Switch 7 This switch is used to initialize the CAT-200B. Set this switch to ON. Cycle the power OFF and
back ON. During power-up, the memory will be flushed and reloaded with default values. The voice will
say: "RESET SYSTEM OK." Set dipswitch #7 to the OFF position.
Switch 8 This switch is used to program a new un-lock number. Set switch #8 to ON. The voice will
say: "ENTER CONTROL." After the seven-digit unlock number is entered, set switch #8 to OFF. This
switch is also used to activate the RS-232 port when the CI-200 is connected. Turn the power off set
dipswitch #8 to on and apply power to the CAT-200B.

Chapter 3 - Repeater Control
The CAT-200B has 4 Zones for a total of 32 remote control channels. These channels can be manually
controlled by DTMF commands on the repeater input.
Interrogation of Repeater Control Status by Radio
Key-up and send the control operator code [100] followed by the zone number and a zero. Un-key and
the voice will read back the channels that are turned on in that zone. Example: Read Zone 2 channel
status. If all the channels are turned off, the voice will say: "CLEAR."
Un-key and the voice will say: "ONE FOUR EIGHT"
Changing Repeater Control Status by Radio
To change the status of a channel, key-up and send the control operator code [100] followed by the zone
number, channel number and a [1] to turn the channel ON or a [0] to turn the channel OFF. Un-key and
the voice will read back the zone, channel number and control activity. The voice will say: "ONE ONE
ON." or "THREE FIVE OFF." Example: With a control operator prefix of 100, turn Zone 2 Channel 1 ON.
Un-key and the voice will say: "TWO ONE ON."

Zone 4
* During initialization these control channels are set to the enable position.
Zone 1 - Repeater Control
1. Repeater Transmitter Enable
This is the master repeater switch. This channel must be enabled for normal repeater operation. The
CAT-200B will continue to respond to control operator commands even when the repeater's transmitter
is disabled. This channel will automatically be enabled after a dipswitch #7 initialization reset.
2. Repeater CTCSS Enable
When this channel is enabled, in addition to a COR input, an input from a CTCSS decoder at J3-4 must
also be present before the repeater will activate. A COR input by itself will have no affect. To prevent
loss of control, DO NOT ENABLE THIS CHANNEL unless a CTCSS decoder is connected to J3-4.
3. Repeater CTCSS OR Logic Enable
When this channel is enabled, the COR and CTCSS inputs will function as a (OR) logic input. This means
activity on either the COR or CTCSS inputs will cause the controller to key the repeater's transmitter.
This is a layered command. Therefore, Repeater CTCSS Enable, Zone 1 Channel 2 must be ON or this
control function will have no effect.
4. Repeater ID Enable
When this channel is enabled, repeater voice ID will repeat subject to the setting of the ID timer. This ID
will consist of up to 15 words selected from the voice vocabulary table and is programmed with the
[*3101] command.
5. Courtesy Tone Enable
When this channel is enabled, a courtesy tone will occur when the COR signal is lost. To eliminate the
courtesy tone, turn this channel OFF. The timeout timer will continue to be reset.
6. Transmitter Hang Time Enable
When this channel is enabled, the repeater's transmitter will remain on for a period of time determined
by the COR to Beep and Beep to transmitter drop timers. To make the transmitter turn off the instant
COR is lost, turn this channel OFF. This feature is useful when linking to other repeaters or during band
openings.

7. DTMF Muting Enable
When this channel is enabled, anytime a DTMF tone is received, the audio will be turned off to the
repeater's transmitter. The transmit audio will remain muted until a pre-determined time after the last
DTMF tone is received. During the mute period, cover beeps are transmitted each second to indicate
repeater activity. This feature prevents control commands from being repeated. It provides an extra
measure of security. There may be times when it is desirable to pass the DTMF tones through the
repeater. To temporarily disable DTMF muting, precede the DTMF string with a (#).
8. Repeater Time-Out Enable
Repeater time-out is user programmable with the [*601*] timer programming commands. When the
CAT-200B is initialized, this timer defaults to 3 minutes. When this channel is turned off, the repeater will
not time-out.
Zone 2 – Link Control
1. Link Transmitter Enable
This channel must be enabled for link operation. The CAT-200B will respond to the link 5001 on and
5000 off commands. This channel will automatically be enabled after a dipswitch #7 initialization reset.
2. Link CTCSS Enable
When this channel is enabled, in addition to a COR input, an input from a CTCSS decoder at J3-3 must
also be present before the repeater will activate. A COR input by itself will have no affect.
3. Link Receive Only Enable
This channel must be enabled for link receive only operation. The CAT-200B will respond to the link
receive only 5002 on and 5000 off commands. Any signals received by the link will be heard on the
repeater's transmitter. However, conversations on the repeater will not be rebroadcast on the link
transmitter.
4. Link Control Enable
The CAT-200B will only respond to the Link control commands [5000] and [5001] through the link input.
This greatly reduces the possibility of the CAT-200B responding to a command meant for another
repeater in the linking system. When this channel is enabled, link control commands will be accepted
through the link receiver input.
5. Link Voice Enable
When this channel is enabled and the link is enabled, voice messages will be transmitted by the
transceiver. When this channel is off, PTT #2 will not activate unless repeater COR #1 is active.
6. Link Auto Disconnect Enable
When this channel is enabled, the link will disconnect automatically after a period of repeater inactivity.
The voice will say: “LINK TIME OUT”. A repeater or transceiver COR will keep the link activate until the
repeater returns to rest. A rest period of up to 29 minutes can be selected with the [*604*]
programming command. When the CAT-200B is initialized, this timer defaults to 10 minutes.
7. Link To Repeater Output
This channel should be enabled when the transceiver on port 2 is linked to the output of a repeater. The
repeater port time-out-timer is reset the instant repeater COR drops. The link port time-out-timer is
disabled and the CAT-200B will identify in CW only.

3-5
8. Link Time-out Enable
Link time-out is user programmable with the [*602*] timer programming commands. When the CAT-
200B is initialized, this timer defaults to 3 minutes. When this channel is turned off, the repeater will not
time-out. Zone 3 – Logic Inputs – Switch Outputs
1. Logic Input #1 Enable
When this channel is enabled, a logic active high input on connector J3-1 will activate voice message #3.
This message is user programmable. The default message is “EMERGENCY POWER”.
2. Logic Input #2 Enable
When this channel is enabled, a logic high input on connector J3-2 will activate voice message #4. This
message is user programmable. The default message is “WEATHER ALERT”.
3. Logic Input #3 Enable
When this channel is enabled, a logic high input on connector J3-21 will activate voice message #5. This
message is user programmable. The default message is “INTRUDER ALERT”.
4. Logic Input #4 Enable
When this channel is enabled, a logic high input on connector J3-22 will activate voice message #6. This
message is user programmable. The default message is “HIGH TEMPERATURE”.
5. Switch #1 Enable
When this channel is enabled, switch #1 is turned on. Connector J3 pin 14 will sink 50 MA to ground.
6. Switch #2 Enable
When this channel is enabled, switch #2 is turned on. Connector J3 pin 15 will sink 50 MA to ground.
7. Switch #3 Enable
When this channel is enabled, switch #3 is turned on. Connector J3 pin 19 will sink 50 MA to ground.
8. Switch #4 Enable
When this channel is enabled, switch #4 is turned on. Connector J3 pin 20 will sink 50 MA to ground.
Zone 4 - Miscellaneous Control
1. DTMF Pad Test Enable
When this channel is enabled, a repeater user is able to perform a test of their radio's 12 or 16-button
keypad. As the numbers are being decoded, they are stored in memory. When the repeater user stops
transmitting the controller will read back all the numbers that were decoded.
2. Beacon Mode
When this channel is enabled and there is no activity on the repeater, the CAT-200B will announce voice
message 7 at an interval rate determined by the Beacon Timer [*605*]. Message 7 defaults to: “CAT-
200B BEACON.” The Beacon Timer defaults to one minute.
3. Weather Report Enable
When this channel is enabled, a repeater user is able to request a weather report.

3-6
4. Fan Control Enable
When this channel is enabled, and PTT #1 turns ON, the Fan Control output J3-8 will turn ON. After PTT
#1 turns OFF this fan control output will remain ON for an additional 60 seconds. Use this output to
control a fan relay to cool the repeater’s transmitter. When this channel is enabled, User function switch
#6 on, off, and momentary operation is not available.
5. Voice Identification Enable
When this channel is enabled, the CAT-200B will identify in voice, using message #1. When this channel
is disabled, the CAT-200B will identify in CW only.
6. Voice Identification Link Inhibit Enable
When this channel is enabled, the CAT-200B will not accept an input from the link port while the voice
identification is being sent on the repeater port.
7. Forced DTMF Entry D Key
When this channel is enabled it is possible to force a DTMF command even while port #1 is active. To
force a DTMF command, end the command with a [D].
8. CTCSS Encoder Switch Enable
When this channel is enabled, user output switch #5 is converted into a CTCSS Encoder Switch output.
When Port #1 goes active, user output #5 J2 pin 7 will turn ON. After Port #1 goes inactive, user output
#5 will turn OFF. Use this output to control an external CTCSS encoder. When this channel is enabled,
User function switch #5 on, off, and momentary operation is not available.
