Previous view 9 D-STAR OPERATION Low-speed data communication In addition to digital voice communication, low-speed data communication can be made. Use the supplied USB cable or the optional OPC1529R data communication cable with a third-party serial data communication software. DDConnection Connect the transceiver to your PC using the USB cable or the OPC-1529R cable, as illustrated below. IC-7100(Rear panel) To a [RS-232C] port To a To the PC [USB] [DATA1] jack port OPC-1529R （Option） Supplied USB cable To a [USB] port Before starting low-speed data communication: The "DV Data TX" item is set to "Auto" by default. So, depending on the data communication application software, the transceiver may automatically transmit the data only when you input text on the software screen. NOTE: Before starting, be sure to set the Set mode items; • Set the "GPS Out" option to "OFF". (p. 17-25) Connectors > USB2/DATA1 Function > GPS Out • Set the "GPS TX Mode" option to "OFF". (p. 10-16) GPS > GPS TX Mode Connect the USB cable • Set the "USB2 Function" option to "DV Data". (p. 17-25) Connectors > USB2/DATA1 Function > USB2 Function Connect the OPC-1529R cable • Set the "DATA1 Function" option to "DV Data". (p. 17-25) Connectors > USB2/DATA1 Function > DATA1 Function DDLow-speed data communication application setting Configure the serial data communication software as follows. • Port: The COM port number which is used by the IC-7100.*1 • Baud rate: 4800/9600 bps*2 • Data: 8 bit • Parity: None • Stop: 1 bit • Flow control: Xon/Xoff *1 Depending on the PC environment, the COM port number used by the IC-7100 may be higher than 5. In such case, use the application that can set it to higher than 5. *2 T he baud rate can be set in the "DV Data/GPS Out Baud" item of the Set mode. (p. 17-26) SET(C) > Connectors > USB2/DATA1 Function > DV Data/ GPS Out Baud DDL ow-speed data communication operation qqSet your own call sign, UR call sign and the repeater call sign. wwFollow the instructions of the data communication application software. eeWhen data is input from a PC, the transceiver automatically transmits it. • The TX/RX indicator lights red. • Push [PTT] to transmit the data and a voice signal when "PTT" is selected in the "DV Data TX" item of the Set mode. (p. 17-13) SET (C) > DV Set > DV Data TX • B efore transmission, the transceiver sends approximately 500 milliseconds carrier sense. NOTE: • Only ASCII code can be used for the low-speed data communication. • A message of up to 20 characters can be transmit- ted with a DV voice signal. • Depending on the combination of your PC and your serial data communication software, some data may be lost. • W hile receiving voice communication or low-speed data communication through the internet, some packets may be lost due to network error (poor data throughput performance). In such a case, "L" appears on the LCD to show the Packet Loss has occurred. 9-17
