25pin connector for input and output controls [AUDIO IN, AUDIO OUT1, AUDIO OUT2, PTT, AF UNLOCKED (cos)1, AF UNLOCKED (cos)2 , XMTR's GNDx7, CW, FSK-RTTY, TTL TXD, TTL RXD,  (RS-232: RXD, TXD, DTR, CTS, DSR, RTS, DCD)]  

Selectable SQL polarity (+5V or -5V), according to transceiver type.

Incorporated and selectable on- off cat control circuit.

Selectable TTL or Serial (RS232) data mode.

Selectable remote for ICOM or other type transceivers.

Full serial port output (in 25 pin socket), for cat control.

True FSK-RTTY mode.

CW mode interacting to transceiver's carrier.

Independent indications for cat control RX, TX data, FSK-RTTY and CW modes, as well as for power on, RX-TX and lock.

Full surface mount components, with no modules (as previous models).

Second receiver audio input.
