In addition to digital voice communication, low-speed
data communication can be made.
Use the supplied USB cable or the optional OPC-
1529R
data
communication
cable
with a third-party
serial data communication software.
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.
• While 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.
Set your own call sign, UR call sign and the repeater
q
call sign.
Follow the instructions of the data communication
w
application software.
When data is input from a PC, the transceiver auto-
e
matically 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)

• Before transmission, the transceiver sends approximate
-
ly 500 milliseconds carrier sense.
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

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.

The baud rate can be set in the “DV Data/GPS Out
Baud” item of the Set mode. (p. 17-26)

NOTE:
Before starting, be sure to set the Set mode
items;
• Set the “GPS Out” option to “OFF”. (p. 17-25)

Low-speed data communication operation
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.
