6.5 DIP switch and jumper settings
GC80 and GC85 Gyro systems include several DIP switches and jumpers.
With the exception of 2 switches on the ICNT board in the Control unit, no
switches have to be set when installing the system. These 2 switches are
set to configure the Control unit to match the type of Gyro system (GC80
or GC85), and to activate an external heading sensor.
Note!
All DIP switch settings are read when the system is started. Any changes
made while the system is running will therefore not take effect until the
system is restarted.
