1. ADVANCED CONNECTIONS FSK, AFSK, PSK connections The transceiver has a mode keys for RTTY and PSK. You can use a PC and an application software to operate RTTY and PSK using a USB cable. However, if you want to operate AFSK or other digital modes, you can use the ACC socket on the rear panel through an interface unit. See the interface circuit diagram below for details. Refer to the software application's instruction manual for setup details. (Icom does not guarantee performance of the application software, PC, network device or network settings.) When using the USB port To a USB port PC To the USB port Type A A/B USB cable (user supplied) Type B TIP: ••If you set the "USB Serial Function" item to "RTTY Decode," the decoded RTTY signals are output from the USB port. ••Download the USB driver and the installation guide from the Icom website. http://www.icom.co.jp/world/index.html (Support > Firmware Updates/Software Downloads > Transceiver) When using the ACC socket or the microphone connector Interface circuit example for digital modes (User supplied) ••Connecting to [ACC 1] D C ４２５ E １８３ B ６７ A E Shield cable D C ACC: Connect to [C] MIC: Connect to [F] 2 kΩ: 2 kΩ 10 kΩ 10 kΩ (Trimpot) Shield cable 2 kΩ: 2 kΩ Shield cable 10 kΩ (Trimpot) 10 kΩ Connect to LINE IN or MIC IN No connection Connect to SP OUT (Rear panel) B A ★1 No connection Shield cable E CB 4.7 kΩ ★2 D-Sub 25 D-Sub 9 RTS ••Connecting to [MIC] GND Pin 4 Pin 7 Pin 7 Pin 5 PC D Connect to E ★1 COM port 1 7 F 286 C 3 5 4 B E CB 4.7 kΩ ★2 TXD Pin 2 Pin 3 (Front panel) Shield cable NOTE: You cannot operate FSK RTTY when you connect the circuit to ★1: NPN transistor (2SC1815) the microphone connector. ★2: S witching diode (1S1588) The sections shown in short dashes are required only when Baudot RTTY is used in the FSK (RTTY) mode. (Not required for other digital modes such as SSTV or PSK) LSee pages 13-2 to 13-3 in the Basic Manual for details on the ACC 1 socket and MIC connectors. 3
