Table 8 TT-3020C X4 pin assignment
The I/O connector, a standard DB-15 female connector, is located
on the rear panel of the transceiver and is marked X4.
2.5.3.1
NMEA 0183 Reception
The NMEA 0183 Standard uses the ASCII alphabet to send strings
containing navigational data. This data can be read by the Trans-
ceiver via the I/O NMEA interface connector X4.
The following is a list of the NMEA codes that the Transceiver will
recognise with or without a built-in GPS.
