GTR 200/200B Installation Manual

Rev. P

Page 4-4

4.6 Serial Data – RS-232

Section 4.6.1.1 details the formats that can be selected for the RS-232 channel.

NOTE

The GTR 200/200B can be installed into the G3X system using an RS-232 or CAN bus

(preferred) connection.

4.6.1 NMEA Format
4.6.1.1 Legacy NMEA Support

The GTR 200/200B maintains backwards compatibility with legacy SL30/SL40 NMEA commands

($PMMRC and $PMMRV) as they apply to GTR 200/200B functionality. Refer to

Appendix B

The following legacy SL30/40 input commands are supported as-is:

• Set active COM frequency (SL30 version)

• Set active frequency and transceiver function (SL40 version)

• Set standby COM frequency. (SL30 version)

• Set standby frequency and transceiver function. (SL40 version)

• Squelch Override On/Off

• Remote Ident Input

• Remote Frequency List Input

4.7 MIC Audio

PILOT MIC IN and COPILOT MIC IN are standard carbon or dynamic MIC inputs with integrated

preamps providing minimum 20 mVrms into a 150 Ω AC load.
PILOT MIC IN and COPILOT MIC IN are set in the factory so that 150 mVrms modulates the transmitter

to 90% nominally at 1000 Hz. The microphone gain adjustment is made through Configuration Mode.
