750’s not cross talking

[timmccall]

I have dual 750’s, JPI 930 and a G500txi. The fuel and OAT info from the JPI is showing on the number 1 750 but is not showing on the number 2. The cross talks are both present in the maintenance pages, both show data transfer enabled and both show use sensors on the fuel page (paraphrasing the terminology). Both 750’s are set the same. Flight plans and XM are showing on both and I can edit from both so they are talking.
Should I see the JPI info on both? I have been searching the IM and configuration manuals but cant seem to find an explanation. Possibly a piggyback on the 232 input from number one to two? Thanks
