Installation Manual
MX500/BRIM Dual-Control with Integrity Monitoring Fea-
ture
The Integrity Monitoring (IM) feature allows the two dual-control MX500 units to
constantly compare each of the two GPS position solutions and, if configured
to do so, give an alarm and/or automatically switch to the unit with the "better"

GPS solution.

Both Master and Slave units are functional D/GPS receivers and both continu-
ously calculate GPS solutions. The IM algorythm continuously compares the
two position solutions. If the GPS Source is set to Automatic, it begins by
using the Master calculated position. However, it continuously compares the
"used" solution to the "other" solution. If the "other" solution is better, it will
switch to use that position solution. Essentially, the Master mode will transfer
automatically to the unit whose position solution is being used for navigation.
