4.9.1 RMI/OBI
Function
The MAIN OBI output provides bearing information from the active waypoint for Bendix/King Serial
OBI devices based upon the 500W Series unit’s GPS navigation. For the GNS 530W, the MAIN OBI
output may be configured so that it sends VOR/ILS bearing information when VLOC is selected by the
GNS 530W CDI key.
The VOR OBI output provides bearing information from the currently tuned VOR station for
Bendix/King Serial OBI devices based upon the GNS 530W VOR receiver. When a localizer channel is
tuned on the VLOC window, there is a bit in the data stream set to indicate that a localizer frequency is
tuned which stows the needle or drive it to the 3 o’clock position.
