(1200 bps: AFSK/ 9600 bps: G3RUH, GMSK) Input level (1200 bps) : 100 mV Input level (9600 bps) : 0.2 to 0.5 Vp-p GND Common ground for DATA IN, DATA OUT and AF OUT. --- PTTP PTT terminal for packet operation. Input voltage (High) Connect to ground to activate the Input voltage (Low) transmitter. : 2.0 V to 20.0 V : -0.5 V to +0.8 V DATA OUT* Data out terminal for 9600 bps operation only. Output impedance Output level : 10 k˘ : 1.0 Vp-p AF OUT* Data out terminal for 1200 bps op- Output impedance eration only. Output level : 4.7 k˘ : 100-300 mV rms SQL* Squelch out terminal. This pin is SQL open grounded when the transceiver receives a signal which opens the SQL closed squelch. • T o avoid interfering transmissions, connect squelch to the TNC to inhibit transmission when squelch is open. • Keep RF gain at a normal level, otherwise a "SQL" signal will not be output. : L ess than 0.3 V/ 5 mA : M ore than 6.0 V/ 100 µA * The pin 4 (DATA), pin 5 (AF) and pin 6 (SQL) output capabilities are for the MAIN Band's AF and squelch by default. You can change this setting in "DATA AF/SQL Select" of the Set mode. (p. 166) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 14
