In addition to the conventional GP-39 settings, the following items are added.
Prohibited GNSS satellite (QZSS, GPS, GLONASS, Galileo)
Offset (Heading, Pitch, Roll, SOG/3-Axis SPD, Air Pressure, Air Temperature)
Smoothing (SOG/COG, 3-Axis Speed, ROT)
DR time
Ship size, antenna location, 3-axis speed position
I/O Setup (Data2, Data3) (Data 2 is output only)
While the SCX-21 has three (3) output ports, Data 1 is used to connect to the GP-
39 and NMEA0183 data is output from Data 2 and 3.

3. Interconnection and Settings
3.1. Interconnection
Notes:
(1)
When the SCX-21 is connected to the GP-
39, the original antenna GPA-017 or
GPA-C01 CANNOT be used.
(2) In the configuration of an SCX-21 with a GP-39, the GP-39 NMEA0183 output port is occupied
by the SCX-21. In order to output/input data from/to the SCX-21, utilize Data 2 and
Data 3 ports of SCX-21. (Data 2 is output only)
3.2. Setting – Operation Mode
Change the operation mode of the GP39 to make the GP-39 work as an SCX-21 display.
Option 1 – When turning the power on for the
first time…
When the SCX-21 is turned on for the first time,
the Installation menu will launch: Access
[Operation Mode] and select [SCX-21].
(Default: [GP-39]) After changing the mode,
the GP-39 will restart.
Make sure to connect the GP-39 to the SCX-21 – Data 1 port.

Option 2 – If the GP-39 has been turned on
before…
In [Menu] – [System] – [Operation Mode],
select [SCX-21]. (Default) [GP-39]) After
changing the mode, the GP-39 will restart.
3.3. Update Guidance
For a GP-39 with v02.01 or earlier, update to v03.01 or higher to connect to the SCX-
21.
If the GP-39 is already loaded with v3.01 or higher, change the operation mode to
[SCX-21] to use the GP39 with the SCX-21. Set the mode to [GP-39] as default to use
it as a GP-39 with a GPA-017 or GPA-C01 GPS antenna.
