MC-Basic:SYSTEM.DIPSWITCH

SYSTEM.DIPSWITCH reads the value of one or more of the 8 DIPswitch inputs. The variable contains the values of the individual bits in the DIPswitch byte. If SYSTEM.DIPSWITCH is qualified by a bit number, only that input bit is read. SYSTEM.DIPSWITCH returns the value 1 or 0, depending on the setting of the switch.

Bit # 6 directs the system not to load the Config.prg file during system startup.
       0= Config.prg is not loaded.
       1 = Config.prg is loaded. Default value should be 1 during normal operation.

Bit # 7 directs the system to run using the firmware backup file (VxBackup) during system startup.
       0 = VxWorks is loaded. Default value should be 0 during normal operation.
       1= VxBackup is loaded

Bit # 8 is reserved for system use.
