Heading flag logic, as detailed in table 2-4, is programmed with a jumper between P1-68 (Heading Flag
Sense) and configuration ground.
NOTE
If the heading system has a low level flag between 1.5 VDC and 2.7 VDC
(when valid), P1-68 (HEADING FLAG SENSE) should not be jumpered to
ground and P1-53 (HDG_FLG+) must remain unconnected.

2.6.3 Display Cable
The display cable connects the TRC to the WX-1000/SKY497 Display. If a WX-1000 Stormscope® Weather
Mapping System is installed, the same type cable is used to connect the TRC to a WX-1000 processor.
Refer to figure 2-2 (without WX-1000) or 2-3 (with WX-1000) for interconnect wiring information. Pinout
information relating to the WX-1000 processor and display is also provided in tables 2-5 and 2-6.
