3-7
Zone 3 Control Channels
1. Port #3 Transmitter Enable (*)
When this channel is enabled the Port #3 PTT will be active. This channel must be enabled for normal
operation. The CAT-800 will continue to respond to control operator commands even when this channel
is disabled. This channel will automatically be enabled after a dipswitch #7 initialization reset.
2. Port #3 CTCSS Enable
When this channel is enabled, in addition to a COR input, an input from a CTCSS decoder at J3-2 must
also be
present before Port #3 will activate. At default this input is set for “COR and CTCSS active high
logic”. Use programming command (*3632) to change the CTCSS logic input to active low. Use
programming command (*3633) to change the logic to “COR or CTCSS active high logic”. NOTE: To
prevent loss of control, DO NOT ENABLE THIS CHANNEL unless a working CTCSS decoder is connected
to J3-2.
3. Port #3 Receiver Enable (*)
When this channel is enabled the CAT-800 will respond to a RF input from the Port #3 receiver. When
this channel is disabled the Port #3 transmitter will continue to operate by responding to RF inputs from
the Port #1 and Port #2 receivers.
4. Port #3 Turn on Delay Enable
When this channel is enabled, a deliberate and sustained input on Port #3 must be present before the
controller will respond. A time delay of 0.1 to 9.9 seconds can be selected with the [*623*]
programming command. When the CAT-800 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. Echolink® Control Enable
When Port #3 is connected to Port #1 and DTMF Muting (Zone 1 Channel 7) is enabled, a DTMF
command entered through Port #1 will be muted on both the Port #1 and Port #3 transmit audios.
When this channel is enabled, Port #3 transmit audio will be the actual DTMF command. The DTMF
command will continue to be muted on the Port #1 transmit audio.
6. Port #3 Auto-Disconnect Enable (Event Macro 35)
When this channel is enabled, after a period of Port #3 inactivity determined by the setting of the
[*606*] timer, the CAT-800 will execute event macro [35]. The default setting of event macro #35 will
disconnect Port #3 from Port #1.
7. Port #3 DTMF Muting Enable
When this channel is enabled, anytime a DTMF tone is received by the Port #3 receiver, 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 temporarily pass
DTMF tones through the repeater. Precede the DTMF string with a (#). This key can be changed with
the [*29X] programming command.
8. Port #3 Timeout Enable (*)
When this channel is enabled, a continuous signal on the Port #1 input will cause the Port to turn off.
The time-out period is user programmable with the [*603*] timer command. When the CAT-800 is
initialized, this timer defaults to 3 minutes. When this channel is turned off, Port #3 will-not timeout.
