2) Selecting IEC
In IEC, VERSION is not selected.
4. When “SENTENCE” is selected by using , a sentence list is displayed.
5. Select an output sentence by using and set an output cycle.
A cycle can be selected within the range from 1 second to 9 seconds and when OFF is selected,
the sentence is not output.
6. Return control to the BIT RATE selection screen and select BIT RATE by using .
Available bit rates are “38400”, “57600”, “76800”, and “115200”. Normally, “115200” is
recommended.
4.15.4 Setting a serial port
This display unit is equipped with three serial ports to send and receive data with external units. Since
each port can be set for input or output, set according to the purpose. However, as input/output of data
IN/OUT1 and data IN/OUT2 are commonly set, they cannot be set individually.
For instance, if data IN/OUT2 is set for input, data IN/OUT1 is automatically set for input.
In this case also, the baud rate and the output sentence can be set individually.
Determine the input output ports using the following table as the guideline.

Although an output sentence, a cycle, and a bit rate can be set for each port, some bit rates and the
number of sentences may not be set. In this case, select the minimum sentence.
The following serial data can be set.
1) NMEA: Data is output in NMEA format. Available options are Version 1.5, 2.1, 2.3, and 4.0.
2) IEC:
Data is output in IEC format.
3) JRC ： Data is output in JRC format. The bit rate is fixed 1200bps.
4) ROUTE WPT
：
The destination, route, and track in a memory can be transmitted and received
using DATA IN/OUT2, 3. (Refer to 4.15.16.1 Outputting Waypoint, Route and
Track" for detail)
Since data is transmitted between display units, some time lag occurs at the switching of
display.
When the bit rate is set to 115,200bps (Max speed), up to 4 sentences can be output.
