D-STAR OPERATION
4-27
In addition to digital voice communication, you can
send and receive data. And you can use the DV Fast
Data function for data communication.
The DV Fast Data function uses the data and the
audio frames to send data approximately 3.5 times
faster than the normal speed. So, no audio can be
sent. To send and receive data, the optional OPC-
2350LU and a data communication software (user
supplied) are required.
NOTE:
• Only the ASCII code can be used for data
communication.
• The standard Message Transmission function also
transmits up to 20 characters. (pp. 4-17, 4-18)
• Depending on the combination of your PC and your
communication software, some data may be lost.
• While receiving voice or data through the internet,
some packets may be lost due to network error
(poor data throughput performance). In such a
case, an “L” is displayed on the screen to indicate
that packet loss has occurred.
D
Sending data
1. Set your own call sign, the UR call sign and the
repeater call sign.
2. Follow the instructions of your data
communication application software.
3. When you enter text data into your communication
software, the transceiver may automatically
transmit it, depending on the software and the
software settings.
L
When “DV Data TX” is set to “PTT,” pushing [PTT]
transmits the text data and a voice signal. (p. 9-48)
(DV Set > DV Data TX)
L
Before transmission, the transceiver sends
approximately 500 milliseconds of carrier sense.
D
Connection
Connect the transceiver to your PC using the optional
OPC-2350LU, as shown below.
D
Data communication application setting
Set the communication software, as shown below.
•Port:
The COM port number that is used by
the ID-4100A/E.*
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 ID-4100A/E may be higher than 5. In that
case, use an application that can set it to higher than 5.
*
2
Set the baud rate in “Data Speed.”

NOTE: Before staring data communication
“DV Data TX” is set to “Auto” as the default setting.
So, when you enter text data into your
communication software, the transceiver may
automatically transmit it, depending on the software
and the software settings.
NOTE: Before you start sending data, be sure to
set the following items.
• Set “GPS SELECT” to other than “External GPS.”
(GPS > GPS Set >
GPS Select
)
• Set “GPS OUT (To DATA Jack)” to “OFF.”
(GPS > GPS Set >
GPS Out (To DATA Jack)
)
• When “GPS TX Mode” is “D-PRS,” set “TX Format”
to other than “Weather.”
(GPS > GPS TX Mode > D-PRS >
TX Format
)
