CTCSS Tone
Panel
. The Tone Panel option provides one remotely programmable
crcss
encode and up .to eight programmable CTCSS decode
frequencies. The board is supplied standard with provisions for
one tone (encode
or
decode) and can accommodate up to seven
additional decode tones by adding chips.
The '96 controller provides Control Op selectable CTCSS
modes, requiring tone encoding on signals to access the repeater
or to access different levels of commands (see Chapter S ­
Access / Control Commands). With the tone panel, the repeater
can recognize one or more programmable tone frequencies.
Each tone can be enabled or disabled independently with Control
Op commands, and the enable/disable status of each tone is
stored in macro sets.
Tone #1 can be selected for decode
or
encode. If selected for
encode, the programmed tone signal is available for injection
into the repeater transmitter. Tones #2;;:.8.:are decode only.
The Tone Panel board installs easily into the RC-96 controller,
with the four provided #4-40 screws and a lO-pin ribbon cable
connecting 110 on the main hoard to 11 on the Tone Panel board.
Of course, install the board with power off !
