Chapter 2 - System Configuration

Repeater With Fixed Frequency Transceiver

In this configuration the CAT-1000B supports a repeater with a CTCSS decoder and a

transceiver on a fixed frequency, second repeater or control receiver. Also shown is

the DVR-1000 Digital Voice Recorder with eight expanded user function switches.

Modular jack J3 connects to the telephone line. A positive voltage applied to the

phone Busy #1 input will disable autopatch activity, when a shared telephone line is

off hook.

Link Transceiver Mode

In the link transceiver mode, the CAT-1000B is optimized to operate in a backbone

linking system. When Zone 6 channels 1 and 2 are enabled, the CAT-1000B will only

accept the Link Connect [5001] and Link Disconnect [5000] commands from the link side.

However, a control bridge can be established using the bridging command. When this

command is entered, the voice will say: "CONTROL UP." The CAT-1000B will now accept

control and programming commands through the link receiver. When the control bridge

is turned OFF the voice will say: "CONTROL DOWN," and the bridging path will be

broken. To connect the bridge, enter [15011]. To disconnect the bridge, enter

[15010]. The [150] bridge prefix can be changed by using the [*502*] programming

command.

Control Receiver Mode

In the control receiver mode, the CAT-1000B will accept a full compliment of control,

programming, and user commands on both the repeater and control receiver inputs.

Commands entered via the control receiver will not produce a PTT #1. When the voice

responds to the commands, PTT #1 will activate. Dipswitches #3, #4 and #5 must be OFF

when a control receiver is connected to RF interface #2.
