5.5 Dip-switch and jumper settings
GC80 and GC85 gyro systems include several dip switches and
jumpers. 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.
