Configuring the Control unit
When the gyro system is shipped from factory, all dip switches
in the Control unit are set as for a standard GC80 system.
Before the system is started, dip switch no.2 on S1 on the SCC
board has to be changed to identify the system as a GC85
system.
The SCC board is located underneath the GTERM board.
