Thor VM3A Vehicle-Mounted Computer 99
CV60 Adapter Cable
An adapter cable is available to attach the Thor VM3A to a vehicle previously
equipped with a CV60 (VM3078CABLE) DC power cable. The adapter cable has a
5-pin connector to match with the CV60 power supply cable on one end and a 6-
pin connector to match to the VM3A on the other end. This section assumes the
CV60 power cable is properly connected to vehicle power. Refer to the CV60 docu-
mentation for details.
When this adapter cable is used, there is no provision for an ignition switch input.
Therefore the vehicle ignition monitoring function is not available when using this
cable.
Connect to CV60 Power Cable
1. Connect the adapter cable to the CV60 power cable by aligning the connector
pins to the power connector; push down on the watertight connector and twist
it to fasten securely.
2. The cable is rated for a maximum temperature of 105°C (221°F). Therefore,
routing this cable, it should be protected from physical damage and from
surfaces that might exceed this temperature. 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.
3. 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.
4. Connect the watertight connector end of the power cable to the dock power
connector by aligning the connector pins to the power connector; push down
on the watertight connector and twist it to fasten securely.
5. Secure the power cable to the computer using the Strain Relief Cable Clamps.
