Screen Blanking Cable

Refer to Screen Control (in the Windows Control Panel) to configure the Thor VM1 for screen blanking.

When routing any additional cables for screen blanking:

•Route the cable the shortest way possible removing any left-over cable

•Fuses and cabling are user supplied. Therefore, route these cables so they are protected from physical damage and from surfaces that might exceed the cable's rated temperature threshold.

•Cable should be protected from physical damage from moving parts

•Do not expose the cable to chemicals or oil that may cause the wiring insulation to deteriorate

•Always route the cable so that it does not interfere with safe operation and maintenance of the vehicle.

•Provide mechanical support for the cable by securing it to the vehicle structure at approximately one foot intervals, taking care not to over tighten and pinch conductors or penetrate outer cable jacket.
