5.5 Dip-switch settings
GC80 and GC85 gyro systems include several dip switches.
With the exception of two switches on the ICIF board in the
Control unit, no switches have to be set when installing the
system. These two switches are set to configure the Control unit
to match type of gyro system (GC80 or GC85), and to activate
an external heading sensor.
Note! These dip switch settings are read when the system is started.
Any changes when the system is running will therefore not take
affect before the system is restarted.
For a complete list of dip switch settings, refer to DIP SWITCH
SETTINGS, page 87.
