2.4.5 Display
See Section 2.3 and Appendix C for display requirements.
Use only high-quality shielded cables for the display connections. Up to 5 m cable
length is normally acceptable.
If the display requires 3 V DC operating voltage, the respective pin on the RJ45 or
D-sub connector may be used. Otherwise, the display should be connected to
power according to Section 2.4.3.
2.4.6 RJ45 – Power and Data Connections
Connecting power to an incorrect pin will burn the circuit
board, make the device unusable, and void any warranty.
The 8-pin RJ45-socket (8P8C) is in accordance with IGC GNSS FR specifications,
except for pin 6.
1: GND
2: GND
3: RX, Fusion receives (RS-232)
4: TX, Fusion sends (RS-232)
5: GND
6: Fusion supplies +3 V DC for display
7: +12 to +32 V DC power supply
8: +12 to +32 V DC power supply
Note: The pin numbering above follows international standard. The pin
numbering in IGC documentation and the PowerFLARM Core manual was
reversed. The pin numbering in different display documentation is mixed.
See the picture above for correct pin assignments.
Do not connect more than one external application to the RJ45 port.
Maximum current on pin 6: 200 mA @ 3 V DC.
Note: Pin 7 of the D-sub connector and Pins 7 and 8 of the RJ45 connector are
internally connected. So are the GND pins 5 (D-sub) and 1, 2, 5 (RJ45).
