Operation
1. Check the F-89 (System version and build date)
settings first on all units. The two parameters O
and P (Option Module) must be the same on all
units before any multiple unit connection can be
established.
Example: F-89 O:00, P:01.
2. All units must be powered down before starting
the Multi-Drop mode configuration.
