This pin feature can be programmed via the CE111 programmer.
The accessible voltage is CMOS Logic Level (H = 5 V).
This pin accepts ALC (Automatic Level Control) voltage from a linear amplifier, to prevent
over-excitation by the transceiver.
This pin is closed to ground while the transceiver's transmitter is engaged.
The capable of switching voltage is 60 V DC, 1 A.
Do not connect any equipment when the FC-30/-40 antenna tuner is connected to
the transceiver.
When this pin accepts 5 V, the transceiver stops the TX output while maintaining the
transmission status.
Do not connect any equipment when the FC-30/-40 antenna tuner is connected to
the transceiver.
This pin accepts a CW key or keyer.
Key up voltage is +5 V, and key down current is 1 mA.
This pin accepts a TX/RX switching line of the FSK/RTTY modem.
Key up voltage is +5 V, and key down current is 1 mA.
This pin is connected to the transceiver's chassis.
This pin is for future expansion of the transceiver's capability.
Do not connect any equipment to this pin.
This pin is for future expansion of the transceiver's capability.
Do not connect any equipment to this pin.
This pin is for future expansion of the transceiver's capability.
Do not connect any equipment to this pin.
This pin accepts a keying line of the FSK/RTTY modem.
Key up voltage is +5 V, and key down current is 1 mA.
When this pin is connected to ground, the transceiver into the transmit mode, and sends
out a steady CW carrier, for linear amplifier adjustment.
This pin accepts the AFSK input from the AFSK modem.
The optimum input level is 60 mVp-p @1 kΩ.
This pin provides 13.8V DC at up to 100 mA, to power an external device.
The transceiver may be automatically be switched to on when the vehicle's ignition key
turned on. Maximum voltage is 13.8 V.
No Connection
This pin outputs the receiver audio (100 mVp-p @1 kΩ) for use with the AFSK modem.
No Connection
This pin feature can be programmed via the CE111 programmer.
The accessible voltage is CMOS Logic Level (H = 5 V).
This pin feature can be programmed via the CE111 programmer.
The accessible voltage is CMOS Logic Level (H = 5 V).
This pin accepts the NMEA data from the GPS receiver (or CAT data for programming
the transceiver).
The accessible voltage is RS-232 Level.
This pin outputs the NMEA data for the GPS receiver (or CAT data for programming the
transceiver).
The accessible voltage is RS-232 Level.
This pin is closed to ground while the transceiver's squelch is closed.
This pin feature can be programmed via the CE111 programmer.
The accessible voltage is CMOS Logic Level (H = 5 V).
This pin is connected to the transceiver's chassis.
