PC CONNECTION FOR DATA COMMUNICATION INSTALLING AND CONNECTING THE TRANSCEIVER 1 CONNECTION TO A PC This transceiver is equipped with data communication connectors (USB and ACC 2) for exchanging audio signals with the auxiliary equipment and connectors (USB and COM) for controlling using PC commands when performing data communication with an external device such as a PC as the auxiliary equipment. To make use of data communication such as RTTY (AFSK), PSK31, SSTV, JT65 and FT8 using data communication software that employs the sound function of a PC and with this transceiver configured to the DATA mode (SSB-DATA, FM-DATA, AM-DATA), set up the connection as follows. • When using the USB audio function: connect to the PC using a USB cable. Data communication with only the USB cable connection is possible by making use of data VOX or PC commands ("TX1;" to start transmission and "RX;" to end transmission) to switch between transmission and reception. (For details on the configuration of the input sound source in the DATA mode and the VOX function, refer to pages 9-2 and 9-3.) • When using an ACC 2 connector: connect the audio output line of the PC to pin 11 (ANI) of the ACC 2 connector and the audio input line of the PC to pin 3 (ANO). Pin 9 (PKS) of the ACC 2 connector, data VOX or PC commands ("TX1;" to start transmission and "RX;" to end transmission) are used to switch between transmission and reception. • When controlling using PC command, connect to the PC with an RS-232C straight cable or a USB cable. To connect with a USB cable, use the virtual COM (Standard) port. • For performing RTTY keying by connecting to a PC (or other external devices) while this transceiver is configured to the FSK mode, please refer to "USING AN EXTERNAL DEVICE FOR RTTY MODE OPERATION" {page 5-51}. To RS-232C Serial Port RS-232C Straight Cable (female) To USB port TS-990S PC USB cable USB (B) Connector Configure the transceiver as follows according to the method of connection with the PC, the specification of the software used for data communication and the settings, etc. ■ BAUD RATE CONFIGURATION FOR PC CONTROL Configure the baud rate of the COM/USB port used for PC control as follows. * Refer to "SELECTING THE BAUD RATE OF THE COM/USB (REAR PANEL) PORT" {page 16-10} When using the USB port: Configure in Menu 7-01 "Baud Rate (USB COM)". When using the COM port: Configure in Menu 7-00 "Baud Rate (COM Port)". ■ AUDIO SOURCE INPUT CONFIGURATION Configure the audio source input for data transmission via PC commands in the SSB-DATA mode as follows. * Refer to "AUDIO SOURCE LINES FOR TX AUDIO" {page 5-11} 1) Press and hold [DATA] to display the audio source input screen. 2) Press [DATA] to switch from "Data Mode Off" to "Data Mode On". Check the "Rear" setting under "Audio Input" for "DATA SEND (PF)" under "TX Method". When using the USB audio function: Configure to "USB Audio" (default). When using the ACC 2 connector: Configure to "ACC 2". Contents Index 1-5
