3-4
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.
