PMDG737 EFIS Offsets for MSFS2020

[Fake Pilot]

*** Moved to FSUIPC7 / MSFS support sub-forum ***

Hi All

I have a CPFlight MCP & EFIS and I'm trying to use Offsets to connect it to and old version of Prosim. Below is the Offset from the 'Mapping for PMDG737-700 document that's installed with FSUIPC 7

EFIS CONTROL PANELS

65BC 2 BYTE x 2 EFIS_ModeSel[2] 0: APP 1: VOR 2: MAP 3: PLAN

Am I right in saying that this line means there are 2 bytes to be used for the MODE Selector, 65BC & 65BD?

And what is the 0 1 2 3 for? Is that the bit number, meaning APP would be entered as 65BC.0?

Many Thanks

Ian.

Yes, 1-byte for each EFIS mode selector switch. There are two EFIS panels, no? So there is one byte per panel.

No, they are the byte values, so each byte will hold one of those values representing the position of the switch in that panel.

Thanks for your reply.

Do you know where I can find the remaining EFIS offsets? The document doesn't list the EFIS push buttons.

WXR, STA, FPV, STD etc etc.

There is no state to the push buttons, they just trigger custom controls:
