Pin 1: When the 9612 Plus needs to key your transmitter, it will apply a ground to
this pin. This is an open-drain circuit and requires a positive voltage from your
radio (not to exceed 50 volts and 200 mA).
Pin 2: This pin connects to the discriminator output from your radio (high speed
receive data — e.g., 9600 baud).
Pin 3: This pin connects to the modulator (normally to the varactor) of your radio
for transmitting high speed (e.g., 9600 baud) packet.
Pin 4: This pin can be used to receive high speed (e.g., 9600 baud) data from
those radios that provide TTL level voltages for receive. Normally, this pin will
not be used.
Pin 6: This pin is the CONTROL A output from the 9612 Plus which may be
used as a control line to your radio or other devices. It is an open-drain circuit,
and will apply a ground on this pin when controlled by the CTRL command in
your 9612 Plus (not to exceed 50 volts and 200 mA).
Pin 7: This pin is the CONTROL B output from the 9612 Plus which may be
used as a control line to your radio or other devices. It is an open-drain circuit,
and will apply a ground on this pin when controlled by the CTRL command in
your 9612 Plus (not to exceed 50 volts and 200 mA).
Pin 8: This line is used to monitor adjustment of the receive equalization of the
high speed (e.g, 9600 baud) modem in the 9612 Plus. Connect a dc voltmeter to
this pin and use the EQUALIZE command to adjust modem equalization for
maximum reading while you are receiving another station.
Pin 9: This pin connects to the ground of your 9600 baud radio.
Pin 10: This pin is connected to ground (same as pin 9).
Pin 11: This pin is connected to ground (same as pin 9).
