When the SCX-21 is connected to the GP-
39, the original antenna GPA-017 or
GPA-C01 CANNOT be used.

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)

When the SCX-21 is turned on for the first time,
the Installation menu will launch: Access
