Zone 1 Repeater Control
1. Repeater Transmitter Enable
This is the master repeater switch. This channel must be enabled for normal repeater
operation. The CAT-1000B will continue to respond to control operator commands even
when the repeater's transmitter is disabled. This channel will automatically be
enabled after an initialization reset.
2. Repeater CTCSS Enable
When this channel is enabled, in addition to a COR input, a positive logic input from
a CTCSS decoder at J4-4 must also be present before the repeater 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 J4-4.
3. DTMF Access Enable
When this channel is enabled, a DTMF Access number selected by programming command
*505* must be entered to activate the repeater. Once this number is entered and the
user un-keys, the voice synthesizer will say: "OK". A COR input will activate the
repeater until it returns to rest. A rest period of up to 29 minutes can be selected
with the [*602*] programming command. When the CAT-1000B is initialized this timer
defaults to 60 seconds. This timer can be bypassed returning the repeater to DTMF
Access by sending the DTMF Access number.
4. Repeater CTCSS Override
When this channel is enabled, and CTCSS is also enabled, a repeater user without a
CTCSS encoder can activate the repeater by entering the DTMF Access number. Once this
number is entered and the user un-keys, the voice will say: "OK". A COR input will
activate the repeater until it returns to rest.
5. Turn on Delay Enable
When this channel is enabled, a deliberate and sustained input 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 [*603*] programming command. When the CAT-1000B is initialized,
this timer defaults to 1.0 seconds. This channel is useful during periods when noise
bursts are present on the repeater input.
6. DTMF Window
When this channel is enabled the controller will only accept DTMF entries when the
window is open. The pre-window timer programming command [*613*] sets the time the
window opens after the presents of COR. The length of the time the window remains
open is set by the window timer programming command [*614*]. When the CAT-1000B is
initialized the pre-window timer defaults to 2 seconds and the window timer defaults
to 8 seconds. Therefore the CAT-1000B will only accept DTMF entries from 2 to 10
seconds after initial COR. The control operator prefix and unlock numbers are exempt
from DTMF Window operation.
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. This time is set by the [*606*]
timer programming command. During the mute period, cover beeps are transmitted each
second to indicate repeater activity. This feature prevents control commands from
being repeated. It provides a 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 pound (#). Refer to Zone 5 Channel 8 for
additional information.
