Chapter 1 - Introduction and Specifications
Congratulations on your purchase of the CAT-250 Repeater Controller. Programming the CAT-250 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. An optional
WINDOW EDITOR is available to program the CAT-250 controller.
Voice Synthesizer
A vocabulary base of 290 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. Or ID in CW only, depending on how the CAT-250 is configured.
Digital Voice Clock
The digital voice clock will announce the time upon request, during repeater IDs, or on the hour through the grandfather clock feature. Back-up power for the clock is supplied by a .47 Farad capacitor. Once 12VDC is supplied to the CAT-250 three hours are required for the capacitor to reach full charge. During power failure the capacitor will power the clock for approximately six hours.
Scheduler
An advanced [20] position scheduler fully automates repeater operation. Any command that can be manually executed can also be scheduled to one-minute accuracy. Program the hours, minutes, day of week, or day of month and month of year. The CAT-250 will do the rest.
Courtesy Tone
Separate courtesy tones denote repeater and link activity. Create up to eight custom courtesy tones and assign their use by executing event macro 13 Port #1 input and macro 14 for Port #2 input.
Port Configuration
The CAT-250 is a dual port controller. Port #1 is a repeater port. Port #2 can be configured as a simplex transceiver or duplex transceiver port.
User Function Output Switches
Six open DRAIN user function output switches control equipment at your repeater site. These switches are controlled manually by DTMF commands or from within a macro. They can be made to turn OFF,
ON or momentarily change state.
User Function Inputs
Four inputs activated by a voltage change from other equipment at the repeater site, causes the CAT-
250 to activate a macro. Two macros are assigned to each logic input. Different macros are called when the input goes high and low.
DTMF Keypad Test
A DTMF keypad test will read back the numbers decoded in a synthesized voice. This feature is available on both ports one and two.
1-1
User Macros
The CAT-250 supports forty User Macros each containing sixteen commands. A user macro is a series of commands, defined by the repeater owner. Macros permit the owner to customize certain aspects of repeater operation. Once the CAT-250 decodes the macro number, the commands will execute in the order they were stored within the macro.
Event Triggered Macros
An event macro is a series of commands, defined by the repeater owner. Event Macros are positioned throughout the program to execute during certain prescribed operations. The CAT-250 supports fifty event macros each containing sixteen commands.

Repeater With One Transceiver And Weather Receiver
In this configuration the CAT-250 supports a repeater, transceiver and weather receiver. The WX-
250 weather receiver mounts on the same 19-inch rack panel as the CAT-250. PTT and transmit audio from the CAT-250 are connected to the repeater's transmitter through the normally closed contacts of the double pole double throw relay located inside the WX-250. When a weather alert is received, the relay will switch the weather alert audio to the TX audio input and provide a PTT signal to key the transmitter.

Dip Switch
An eight-position dipswitch configures various functions of the CAT-250.
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 the operation of Port #2. Switch #5 should be ON for duplex transceiver operation and OFF for simplex transceiver operation.
Switch 6
This switch places the CAT-250 in the cross band repeat mode. With transceivers on both
Port #1 and Port #2, enabled the link with the [5001] command. A signal received by the Port #1 receiver will only key the Port #2 transmitter and a signal received by the Port #2 receiver will only key the Port #1 transmitter.
Switch 7
This switch is used to initialize the CAT-250. 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 MASTER un-lock number. Set switch #8 to ON. The voice will say: "ENTER CONTROL." After the seven-digit master unlock number is entered, set switch
#8 to OFF. This switch is also used to activate the RS-232 port. Turn the power off set dipswitch #8 to on and apply power to the CAT-250.
2-6
Chapter 3 - Repeater Control
The CAT-250 has eight control zones. These control zones can be manually controlled by DTMF commands on the repeater input or by user and event macros.
Interrogation of Repeater Control Status
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."
Zone (2)
Control Operator Code Read Channel Status (0)
Key-up and send: 100 2 0
Un-key and the voice will say: "ONE FOUR EIGHT"
Changing Repeater Control Status
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. Unkey 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.
Zone (1 through 4)
Control Operator Code Channel (1 through 8)
Activity (0=OFF 1=ON)
Key-up and send: 100 2 1 1
Un-key and the voice will say: "TWO ONE ON."
Control of the CAT-250 is also available through the Port #2 receiver. The procedure is the same as above except the default control operator code for Port #2 is [200].

Zone 1 - Repeater Control Channels
1. Port #1 Transmitter Enable
This is the master repeater switch. This channel must be enabled for normal repeater operation. The
CAT-250 will continue to respond to control operator commands even when the Port #1 transmitter is disabled. This channel will automatically be enabled after a dipswitch #7 initialization reset.
2. Port #1 COR and CTCSS Enable
When this channel is enabled, in addition to a COR input, an input from a CTCSS decoder at J2-4 must also be present before Port #1 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 J2-4.
3. Port #1 COR or CTCSS 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 Port #1 transmitter.
4. Port #1 Turn on Delay Enable
When this channel is enabled, a deliberate and sustained input on Port #1 must be present before the controller will respond. A time delay of 0.1 to 9.9 seconds can be selected with the [*624*] programming command. When the CAT-250 is initialized, this timer defaults to 1.0 seconds. This channel is useful during periods when noise bursts are present on the repeater input.
5. Port #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 through the repeater port. 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. The Forced DTMF Entry key is defaulted to the [D] key. It must be entered last and it will not read back during the pad test.
6. Port #1 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.
7. Port #1 DTMF Muting Enable
When this channel is enabled, anytime a DTMF tone is received, the audio will be turned off to the Port
#1 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 (#).
3-4
8. Port #1 Timeout Enable
Port #1 time-out is user programmable with the [*601*] timer programming commands. When the
CAT-250 is initialized, this timer defaults to 3 minutes. When this channel is turned off, the repeater, port #1 will not timeout.
Zone 2 - Link Control Channels
1. Port #2 Transmitter Enable
This channel must be enabled for link operation. This channel will automatically be enabled after a dipswitch #7 initialization reset.
2. Port #2 COR and CTCSS Enable
When this channel is enabled, in addition to a COR input at J2-5, an input from a CTCSS decoder at J2-
3 must also be present before the repeater will activate. A COR input by itself will have no affect.
3. Port #2 COR or CTCSS 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.
4. Port #2 Turn on Delay Enable
When this channel is enabled, a deliberate and sustained input on Port #2 must be present before the controller will activate the repeater. A time delay of 0.1 to 9.9 seconds can be selected with the
[*624*] programming command. When the CAT-250 is initialized, this timer defaults to 1.0 seconds.
This channel is useful during periods when noise bursts are present on the transceiver input.
5. Port #2 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 through Port #2. 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. The
Forced DTMF Entry key is defaulted to the [D] key. It must be entered last and it will not read back during the pad test.
6. Port #2 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 [*607*] programming command. When the CAT-250 is initialized, this timer defaults to 10 minutes.

7. Port #2 DTMF Muting Enable
When this channel is enabled, anytime a DTMF tone is received, the audio will be turned off to the Port
#2 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. Port #2 Timeout Enable
Link time-out is user programmable with the [*602*] timer programming commands. When the CAT-
250 is initialized, this timer defaults to 3 minutes. When this channel is turned off, the repeater link port, will not timeout.

Chapter 4 - Repeater Operation
Time of Day Message
Key-up, and enter [400], the time of day access code. Un-key, and the voice synthesizer will announce the time. Example: The voice will say: "THE TIME IS 7:30 PM". The time of day announcement is stored in voice message [9] and can be changed with the [*3109] programming command.
DTMF Keypad Test Port #1 and Port #2
Key-up, and enter [375], the DTMF keypad access code followed by the keypad numbers and letters to be tested. The entries can be in any order. Un-key, and the voice will read-back all numbers and letters that were decoded including the "STAR" and "POUND". The Forced DTMF Entry key is defaulted to the [D] key. It must be entered last and it will not read back during the pad test.
DTMF Access Port #1 and Port #2
When the CAT-250 is in the DTMF Access mode, you must enter the DTMF Access code to activate the repeater. The voice will say: "OK UP" and the repeater will respond to a COR and or CTCSS input.
When the repeater returns to rest, for a time determined by the sleep timer, the DTMF Access code must be re-entered to activate the repeater. You can bypass the rest period and return the repeater to
DTMF access mode by re-entering [325], the DTMF access code. The voice will say: "OK DOWN".
Forced DTMF Command Entry Port #1 and Port #2
During normal operation a DTMF command is entered when the port goes inactive. It is possible to force a DTMF command entry even while the port is active. The CAT-250 will accept the [D] key as an entry command. This key can be changed with the [*29X] programming command.
DTMF Muting Override Port #1 and Port #2
With DTMF muting enabled, there may be times when it is desirable to pass the DTMF tones to the repeater or link transmitter. To temporarily disable DTMF muting, precede the DTMF string with a pound [#].
Repeater ID #1 (At Rest)
If the repeater has been at rest for a period in excess of the ID timer setting, when the repeater is keyed, the CAT-250 will send ID #1. This ID should be longer than ID #2 and include additional information about the repeater or sponsoring organization. Example: "WITH ONE HUNDRED WATTS OF
RF POWER AT YOUR SERVICE THIS IS THE W4XYZ REPEATER SYSTEM -- GOOD AFTERNOON".
Repeater ID #2 (Active)
If a QSO is in progress and it's time to identify the repeater, the CAT-250 will wait until COR drops to send ID #2. This ID should be short so as not to interfere with the QSO in progress. Example:
"W4XYZ REPEATER." This ID is also called as the final ID of the ten-minute period.
4-1
Macro Execute
A macro is a series of commands, defined by the repeater owner. Macros permit the owner to customize certain aspects of repeater operation. Once the CAT-250 decodes the macro number, the commands will execute in the order they were stored within the macro string.
Link Disconnect
Key-up on the repeater or link input and enter the link disconnect control Macro #28 number [5000].
The CAT-250 will disconnect the link port from the repeater port, and the voice will say: “LINK OFF.”

9. The two voice Ids are loaded with “CAT-250 REPEATER”.
10. All messages are loaded with default messages.
11. Event macros are loaded with defaults.
Programming the Master Unlock Number
To program the Master UNLOCK number, set dipswitch #8 to the on position. The voice will say:
"ENTER CONTROL." Key-up and enter a seven-digit number. Un-key, if the number is accepted, the voice will say: "CONTROL OK." If the number is rejected, the voice will say: "ENTER CONTROL." Keyup and enter the seven-digit number. Set dipswitch #8 to the off position.
Unlocking the Controller By Radio From Port #1 and Port #2 [7654321]
To unlock the controller, key-up and enter the unlock number. The voice will say: "CAT 250
CONTROL."
Note: The CAT-250 can be unlocked and placed in the programming mode with either the unlock or the master unlock number. The master unlock number must be changed by using dipswitch #8. The unlock number can be changed remotely without having to go to the site. For security reasons use the unlock number because it can easily be changed. Use the master unlock number when the conditions are thought to be secure.
Locking the Controller By Radio [*0]
Key-up and send [*0]. Un-key, the controller will lockup and the voice will say: "CONTROL EXIT." The controller will lock automatically when the programming timer expires. The voice will say: "TIMER
EXIT." The programming time limit is set by the programming timer [*605*]. The default time is ten minutes.
NOTE: The CAT-250 must be unlocked to perform the following programming functions.

Chapter 6 – Interfacing to Other Equipment
1.

4.
Interfacing the CAT-250 to your repeater system is a simple matter. A minimum of two inputs and two outputs are required for the CAT-250 to control a repeater. They are:
A COR signal to indicate when a signal is being received.
A receive audio signal containing DTMF tones to be processed for control.
A Push-To-Talk signal to tell the repeater transmitter to turn ON.
A transmit audio signal containing a combination of receive audio, synthesized voice, and courtesy tone.
Additional connections are required to realize all features of the CAT-250.
Determining COR Logic
Locate your repeater receiver’s COR output. This line has a DC voltage that changes state when a signal is being received. If the COR line is 0 volts and goes to a positive voltage when a signal is received it is said to be (positive logic) or active HIGH. If the COR line is a positive voltage, and goes to 0 volts when a signal is received it is said to be (negative logic) or active LOW. Note: 0 volts is any voltage less than 0.8VDC. A positive voltage is any voltage greater than 3.0VDC. Set dipswitch #1 on the CAT-250 to ON for (negative logic) and OFF for (positive logic).
Connection to Receiver
Connect the repeater receiver audio output to J2-13 and the COR to J2-6 of the CAT-250. Verify this line changes from less than 0.8VDC to greater than 3.0 VDC. If the COR line will not meet these limits it may be necessary to add a pull-up resistor to the COR #1 line. This may also be true for the COR #2 input. Space is provided on the CAT-250 board to add pull-up resistors.
Connection to Transmitter
Locate your repeater’s Push-To-Talk input. When grounded, this line will make the repeater transmit.
Connect the CAT-250 PTT #1 output (J2-10) to this line. Locate your repeater’s TX audio input. This is the line were the audio signal used to modulate the transmitter is applied. Connect the TX1 AUDIO
(J2-11) to this line.
Connection to CTCSS Decoder
If your repeater receiver has a CTCSS decoder output, connect it to J2-4. In addition to COR, the CAT-
250 requires an active high input to represent a CTCSS input. If the CTCSS input is active low set dipswitch #2 on.
Interface Review
1.
2.
3.
4.
Are dipswitches #1 through #8 in their proper positions?
Is the PTT-1 output at J2-10 connected to the transmitter PTT input?
Is the TX1 Audio at J2-11 connected to the transmitter audio input?
Is the COR-1 at J2-6 connected to the repeater receiver COR output?
5. Is dipswitch #1 ON for active low COR or OFF for active high COR?
6.
Is the COR level changing from less than 0.8 VDC to greater than 3.0 VDC?
7.
Is the RX1 AUDIO at J2-13 connected to the receiver audio output?
8.
Is the audio input level sufficient for the DTMF decoder?
6-1
Connector Kit
Included with the controller is a connector kit containing a 25 pin “D” connector to mate with J2, a
2.5mm power plug to mate with J3 (center pin is [+]), and two 2200 ohm resistors. If the COR inputs are active low, you may need to install the 2200 ohm resistors as pull-ups on the board at the R10 and
R11 positions. If the receiver’s COR circuit in not capable of pulling down the 2200 ohm resistor you may increase the value up to 10K ohms.
Power Supply
The CAT-250 is powered by an external 12VDC power supply. Connect the positive lead of the supply to the center pin of the coaxial power connector J3 and the negative lead to the outer conductor.
Audio De-Emphasis Jumpers (J8-J9)
If the controller is supplied with discriminator audio it is necessary to de-emphasize the audio. With the jumpers installed on J8 (Port #1) and J9 (Port #2), C32 and C33 will be connected across the feedback resistors of the receiver audio amplifiers. This will lower the gain at the higher frequencies and produce the necessary de-emphasis. If de-emphasize audio is supplied to the controller these jumpers should be removed.
Audio Level Adjustment
The audio mixing-switching circuits of the CAT-250 are optimized around an input and output of –
10dBM (220mV).
Connect a signal generator to the repeater’s receiver input. Adjust the signal generator’s output for a standard test signal of 1000 Hz at 3 KHz deviation. If a signal generator is not available, select a handi-talkie that you suspect has the DTMF tone pad adjusted for approximately 3 KHz deviation.
Key-up on the repeater input and send a DTMF tone. Adjust the RX1 control R25 for 220mVAC at TP5.
If a link transceiver is connected to the CAT-250, key-up and send the LINK enable command [5001].

Once the RX1, and RX2 audios are adjusted, key-up on the repeater input and send a DTMF tone.
Monitor the REPEATER transmitter. Adjust the TX1 Audio level control (R15) as required to set the repeater transmitter deviation to 3 KHz or as desired. If the repeaters transmit audio input is very sensitive and you find the TX1 Audio level control near minimum, it is strongly recommended that an external voltage divider be installed at the audio input of the repeater’s transmitter.
If a link transceiver is connected, key-up on the repeater input and send a DTMF tone. Monitor the
LINK transmitter. Adjust the TX2 Audio level control (R16) as required to set the link transmitter deviation to 3 KHz or as desired. If the link-transmit audio input is very sensitive and you find the TX2
Audio level control is near minimum, set the jumper plug at J5 between pins 1 and 2.
Compare the receive and synthesized voice audio and adjust the voice Level (R30) as desired. The synthesized voice should be slightly lower than the receive audio.
Unlock the CAT-250 by keying-up on the repeater input and entering: [1234567]. Key-up and enter the [*901] test tone programming command. Verify that the test tone provides approximately 1.5 KHz transmitter deviation. Key-up and enter [*0] to exit the programming mode.
