I bought a plane with a G400W WAAS (a gps-only 430 without the com).
And a G5 connected serially to the G400, no CANBUS or ARINC connection between them. Both units are recently purchased and installed by an avionics shop (prior owner) and I just updated the G5 software to the latest 7.10 from 6.8.
The G5 is showing a serial data error. I have (and READ!) both manuals. Checking the setup, the data formats selected at each end did not match. The manuals say to make them both preferably MAPMX. OK, doing that.
Q1. Selecting MAPMX on the G5 puts the G5 IN baud rate at an unchangeable 38400. There does not seem to be a baud rate selector on the G400 when selecting MAPMX as its rs232 OUT. Actually there seems to be no baud rate selector for any rs232 out on the G400w. The manuals do not seem to cover this issue - should this work? Will it just magically match?
Q2. The G5 has a setting for VNAV indicator deviation range, of either +- 500 ft or +- 1000 feet when using the serial data in. (ERROR! That setting is NOT for “serial data in”, it is for NAV data in which has to com into the CAN BUS, via an ARINC-to-CAN BUS adapter. My mistake!) It also says to MATCH that range to the output range of the device feeding it. Which is the G400W. I can’t find in the G400 setup or manual what the setting of this range is. (Never mind!)
Thanks!
