Kantronics KAM Plus - Hf

76
Pin 1: Connects to your mic input of your radio, providing the audio signal to be transmitted.
Pin 2: When a ground is applied to this pin and the KAM Plus CD command is set to SOFTWARE,
the KAM will not transmit packet. This is normally used as an external means of supplying
carrier detect to the KAM Plus.
Pin 3: When the KAM 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
or 200 mA).
Pin 4: Receive audio from your radio may be connected to this pin. This will normally be used only
if your radio has its receive audio present on the microphone plug.
Pin 5: This pre-wired mini-plug connects to the external speaker jack on your transceiver for re-
ceive audio. If you use this connection you will not need to use pin 4.
Pin 6: This pin connects to the ground of your radio mic connector.
Pin 7: +12 VDC in – red lead. This lead is provided as an alternate power input. It may be used in
place of the +12 VDC jack.
Pin 8: This pin is also ground. Only one ground needs to be connected to your radio.
Pin 9: This pin is also ground. Only one ground needs to be connected to your radio.
HF
The HF radio connector on the KAM Plus rear panel is an 8-pin DIN style connector with a pre-
wired 9 conductor cable and a mini-plug attached. The cable wiring is:

Pin 1: Connects to your microphone input of your radio, providing the audio signal to be transmit-
ted.
Pin 2: This pin connects to the ground of your radio mic connector.
Pin 3: When the KAM 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
or 200 mA).
Pin 4: This line connects to CW Key jack on your transceiver. When operating CW, the KAM will
ground this pin through a 100 ohm resistor to key your radio. You must have your radio in
CW mode with the VOX turned ON and any electronic keyer turned OFF.
Pin 5: If your radio supports FSK operation, connect this wire to the FSK input of your radio.
Pin 6: This pre-wired mini-plug connects to the external speaker jack on your transceiver for re-
ceive audio. If you use this connection you will not need to use the purple wire. If your ra-
dio provides receive audio on the mic connector, you may use the purple wire instead of
the mini-plug.
Pin 7: Same as pin 6.
Pin 8: When a ground is applied to this pin and the KAM Plus CD command is set to SOFTWARE,
the KAM will not transmit packet. This is normally used as an external means of supplying
carrier detect to the KAM Plus.
