Pin 1 When the KPC-9612 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 (9600 baud receive data).
Pin 3 This pin connects to the modulator (normally to the varactor) of your radio for transmitting
9600 baud packet.
Pin 4 This pin can be used to receive 9600 baud data from those radios that provide TTL level
voltages for receive (such as the Kantronies D4-10 radio). This pin would normally only be
used to operate 19,200 baud packet. Normally, this pin will not be used.
Pin 5 This pin can be used for transmit data for those radios that accept TTL level transmit sig-
nals (such as the Kantronies D4-10 radio). This pin would normally only be used to operate
19,200 baud packet.
Pin 6 This pin is the CONTROL A output from the KPC-9612 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 KPC-9612 (not to exceed 50 volts and
200 mA).
Pin 7 This pin is the CONTROL B output from the KPC-9612 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 KPC-9612 (not to exceed 50 volts and
200 mA).
Pin 8 This line is used to adjust the receive equalization of the 9600 baud modem in the KPC-
9612. Connect a dc voltmeter to this pin and adjust R-33 for maximum reading while you
are receiving another station. (Note: J8 must be on the center post and 2 for this adjust-
ment.)
