4.1.2.1 GDL 51R/52R Aircraft Power Connect pin 10 to aircraft power (14/28 VDC) and pin 9 to aircraft ground (see Appendix B). It is recommended that a 3 Amp fuse or circuit breaker be used to supply power to the GDL 5XR. 4.1.2.2 GDL 51R/52R RS-232 Electrical Characteristics The RS-232 outputs conform to EIA Standard RS-232C with an output voltage swing of at least ± 5V when driving a standard RS-232 load (see Appendix B). 4.1.2.3 Music Output The MUSIC OUT signals are part of a differential pair (along with the MUSIC RIGHT and MUSIC LEFT signals). The MUSIC OUT COMMON signal should be used as part of a differential pair. See Figure B-2 for an example connection to the GMA245 audio panel. 4.1.2.4 GPS Antenna Connection The GPS antenna connection uses a BNC connector, see Section 3.9 for compatible antennas. 4.1.2.5 SXM Antenna Connection The SXM antenna connection uses a TNC connector, see Section 3.9 for compatible antennas. 4.1.2.6 ADS-B Antenna Connection The GDL 52R ADS-B antenna connection uses a BNC connector, see Section 3.7.1 for compatible antennas. 190-02087-10 Rev. 1 GDL 51(R)/52(R) Installation Manual Page 4-4

4.1.2.1
GDL 51R/52R Aircraft Power
Connect pin 10 to aircraft power (14/28 VDC) and pin 9 to aircraft ground (see
Appendix B
).
It is
recommended that a 3 Amp fuse or circuit breaker be used to supply power to the GDL 5XR.
4.1.2.2
GDL 51R/52R RS-232 Electrical Characteristics
The RS-232 outputs conform to EIA Standard RS-232C with an output voltage swing of at least ± 5V
when driving a standard RS-232 load (see
Appendix B
).
4.1.2.3
Music Output
The MUSIC OUT signals are part of a differential pair (along with the MUSIC RIGHT and MUSIC LEFT
signals). The MUSIC OUT COMMON signal should be used as part of a differential pair. See
Figure B-2
for an example connection to the GMA245 audio panel.
4.1.2.4
GPS Antenna Connection
The GPS antenna connection uses a BNC connector, see
Section 3.9
for compatible antennas.
4.1.2.5
SXM Antenna Connection
The SXM antenna connection uses a TNC connector, see
Section 3.9
for compatible antennas.
4.1.2.6
ADS-B Antenna Connection
The GDL 52R ADS-B antenna connection uses a BNC connector, see
Section 3.7.1
for compatible
antennas.
