Data communication

In addition to digital voice communication, you
can send and receive data. Also, you can use the
DV Fast Data function for data communication.
To send and receive data, a USB cable (user
supplied), and a data communication software
(user supplied) are required.
NOTE: "DV Data TX" is set to "Auto" as the
default setting. When you enter text data into
your communication software, the transceiver
may automatically transmit it, depending on the
software and the software settings.

DConnection

Connect the transceiver to your PC using a USB
cable, as shown below.
PC
USB cable
To a USB port
NOTE: Before you start sending data, BE
SURE to set the following items on the USB (B)
FUNCTION screen.
» SET > Connectors > USB (B) Function
• Set "USB (B) Function" to "DV Data."
• Set "GPS Out" to "OFF."

D Data communication application setting

Set the communication software, as shown
below.
• Port: The COM port number that is used by
the IC-705.*
• Baud rate: Your desired speed
• 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-705 may be higher than 5. In
that case, use an application that can set it to higher
than 5.

DSending data

1. Set your own call sign, the destination 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 its settings.
LWhen "DV Data TX" is set to "PTT," pushing
[PTT] transmits the text data and a voice signal.
» SET > DV SET > DV Data TX
LBefore transmitting the data, the transceiver
sends a carrier sense signal approximately 500
milliseconds.
NOTE:
• Only ASCII code can be used for data
communication.
• The transceiver also has a Message Transmission
function that transmits up to 20 characters.
(p. 14-11)
• 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.
