Audio Delay Interface (J8 - J9)
This interface is used to connect a audio delay board. The CAT-1000B is shipped from
the factory with jumpers installed across J8 and J9 at pins 1 and 2. This completes
the receive audio path. Audio delay boards connected to J8 and J9 will eliminate the
receiver squelch noise crash and the chirp of the first DTMF tone when muting is
enabled.

RS-232 Interface (J1)
This interface is used to connect a computer to the CAT-1000B controller. When power
is applied to the CAT-1000B with dipswitch 8 set to ON, programming can be
accomplished directly through this serial port bypassing the internal 300-baud modem.
The serial port of the computer or terminal must be configured for 4800 baud, 8-bit,
NO parity, 1 stop bit. Pins 2 and 3 of J7 must be jumpered. Fabricate a computer
interface cable as shown in Figure 7-2.
