Voice Synthesizer
A [290] word vocabulary carefully selected for amateur repeater operation is available to construct [20] different voice messages. Each message can be [15] words in length. Configure your repeater ID and announcements to suit your particular needs and also have available general purpose messages .

DTMF Key-Pad Test
The key-pad test, available from both ports, will read back the numbers decoded in a synthesized voice. This includes the words "STAR" and "POUND".

Courtesy Tones
The CAT-250 provides individual courtesy tones for both the repeater and remote base inputs. Different courtesy tones can be selected to indicate port activity.

CW ID
The CAT-250 will switch to a CW ID when a user talks over the voice ID.

Repeater Timers
Twelve timers control repeater operation. Each timer is user programmable to afford maximum flexibility to suit your requirements. They are: System ID Timer, System Pending ID Timer, Port #1 and Port #2 Timeout Timers, Programming Length Timer, DTMF Access Sleep Timer, Port #2 Disconnect/ Connect Timer, COR drop to courtesy beep timer and Courtesy beep to transmitter drop timer, Pre-Voice Delay Timer, Turn on Delay Timer, and DTMF Muting Timer.

Link Transceiver Control
The CAT-250 offers full control of the link port. You can turn the link transceiver on and off, through the repeater or remote base port. Separate codes are available for each on/off function.

Computer Interface
The CAT-250, includes a RS-232 port. With the ED250W editor, this port is used to upload new firmware updates available on the C.A.T. website at catauto.com. You never need to change ROMs again. This RS-232 port is also used to upload a new program prepared by the CAT-250 Editor.

CAT-250 Windows® Editor Program
The optional editor program provided on CDROM is used to manage the data file. The editor will work with any computer using a windows® 98, Me, 2000 (or greater) operating system. Use the program to display and make changes to the CAT-250 memory. Once changed, the memory can be up loaded into the controller.

DTMF Decoders
Two DTMF decoders, one for each port, insures reliable decoding of control and programming commands.

Port Configuration
Configure Port #2 as a simplex transceiver or Duplex transceiver port.

Logic Inputs
Four logic inputs activated by a voltage change from other equipment at the repeater site, causes the CAT-250 to activate event macros. One event macro will activate on the positive trigger edge while another macro will trigger on the trailing edge.

Output Switches
Six switches are available to control equipment at your repeater site. Controlled manually by DTMF commands or from a macro command, they can be made to turn ON, OFF or Momentarily change state, any time you choose

Repeater Control Channels
The CAT-250 has 42 remote control channels. Divided into groups, according to their function, they can be manually controlled through the repeater input. They are:

Port #1 Transmitter Enable Port #2 Transmitter Enable
Port #1 COR and CTCSS Enable Port #2 COR and CTCSS Enable
Port #1 COR or CTCSS Enable Port #2 COR or CTCSS Enable
Port #1 Turn on Delay Enable Port #2 Turn on Delay Enable
Port #1 DTMF Pad Test Enable Port #2 DTMF Pad Test Enable
Port #1 Courtesy Tone Enable Port #2 Courtesy Tone Enable
Port #1 DTMF Muting Enable Port #2 DTMF Muting Enable
Port #1 Timeout Enable Port #2 Timeout Enable
Scheduler Enable Port #2 Control Operator Enable
Time-of-Day Request Port #2 Macro Control Enable
Grandfather Clock Enable Port #2 Activity Check Enable
Grandfather Clock Sleep Enable Fan Control Enable
Repeater ID (Rest) Enable Repeater ID (Active) Enable
Squelch Tail Message Enable Transmitter Drop Message Enable
Timed Message #1 Enable Timed Message #2 Enable
DTMF Access Enable Switch Output #1 Enable
Forced DTMF Entry Enable Switch Output #2 Enable
Logic Input #1 Enable Switch Output #3 Enable
Logic Input #2 Enable Switch Output #4 Enable
Logic Input #3 Enable Switch Output #5 Enable
Logic Input #4 Enable Switch Output #6 Enable


CAT-250 System Diagram

Multi Port Operations
In this configuration the CAT-250 supports a repeater and three (3) transceivers. With the RLS-1000B Remote Link Switch board connected to port #2 of the CAT-250, three transceivers can be added to your repeater system. Three (3) of the CAT-250's user function output switches are assigned to control the RLS-1000B's transceiver interfacing.
