14 OTHER FUNCTIONS117■ Packet operationD Data speedFor packet operation, the transceiver can be set to one of twodata speeds: 1200 bps (default) or 9600 bps.q Push [F• ] to display function guide.w Push [MENU](V/MHz•SCAN) (Right band’s) to enter MENUscreen.e Rotate [DIAL] to select “PACKET” then push [MAIN•BAND].r Rotate [DIAL] to select “PACKET BPS” then push[MAIN•BAND].t Rotate [DIAL] to select desired data transmission speedfrom 1200 bps (default) and 9600 bps, then push[MAIN•BAND].y Push [BACK](V/MHz•SCAN) (Right band’s) twice to returnto frequency indication.For 1200 bps operation—• Disconnect the microphone plug from the microphoneconnector during data transmission, otherwise the datasignal and voice signal are simultaneously transmitted.For 9600 bps operation—• When the transceiver is set for 9600 bps data transmissionin set mode, the microphone signal is automaticallycut. Therefore, it is not necessary to disconnect the microphoneplug from the connector in this case.• When pushing [PTT] during data transmission, data transmissionis interrupted and voice signals have priority.DPACKET JACK PIN ASSIGNMENTqetFront panel viewqDATA INInput terminal for data transmit. See left for details on howto toggle data speed between 1200 (AFSK) and 9600 bps(G3RUH, GMSK).wGNDCommon ground for DATA IN, DATA OUT and AF OUT.ePTT PPTT terminal for packet operation only. Connect ground totransmit data.rDATA OUTData out terminal for 9600 bps operation only.tAF OUTData out terminal for 1200 bps operation only.yP SQLOutput is high (+5 V) when the transceiver receives a signalwhich opens the squelch.•To avoid unnecessary TNC transmission, connect squelch to theTNC to inhibit transmission when receiving signals.• Keep audio output at a normal level, otherwise a “P SQL” signalwill not be output.wry
