Dl00 and EMS120 communication problems

[n693w]

I've had a D100 and EMS120 installed in my aircraft since 2008. The EMS is mounted on the right side of my panel and the D100 on the left. I have the right half of the D100 set as EMS display and the EFIS on the left.

In the last week or so intermittently the EMS display disappears and may come back in 2 minutes or 10 minutes.

The EMS120 on the right sided of the instrument panel works normally.

I've checked all wiring and found no problems.

Any suggestions?

If you are intermittently losing display of engine information on your EFIS-D100, but see no disruption on the EMS-D120's display, then the problem could be in the data communication between the EFIS and EMS units.

Your focus should be on the DSAB wires connecting the two units -- blue and green wires. If you have checked the wires and connections and found no intermittent connection issues, then there may be a problem in either the EFIS or EMS unit.
