Thor VX8 / Thor VX9 Adapter Cable
An adapter cable is available to attach the Thor VM2 to a vehicle previously equipped with a VX8/VX9 DC power cable.
The adapter cable has a 6-pin connector to match the VX8/XVX9 power supply cable on one end and a 6-pin connec-
tor to match the Thor VM2 on the other end. The cable also has bare wires for ground and ignition sense connection
plus a D9 cable to connect to a COM port on the Thor VM2 dock to provide a screen blanking signal. This section
assumes the VX8/VX9 power cable is properly connected to vehicle power. Refer to the VX8 or VX9 Vehicle Mounting
Reference Guide for details.
Connect to Thor VX8 / VX9 Power Cable
1. Connect the cable to the Thor VX8/VX9 power cable by aligning the connector pins to the power connector;
push down on the watertight connector and twist it to fasten securely.
2. Connect the green wire to vehicle ground:
3. If ignition control will be used, connect the blue wire to an ignition switched circuit (less than 1mA over input
voltage range). If ignition control is not used, the blue wire can be left disconnected,
4. If the VX8/VX9 cable is connected to a screen blanking box or switch, connect the D9 connector to a COM
port on the dock.
5. The cable is rated for a maximum temperature of 105°C (221°F). Therefore, when 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 opera-
tion and maintenance of the vehicle.
6. Provide mechanical support for the cable by securing it to the vehicle structure at approximately one foot inter-
vals, taking care not to over tighten and pinch conductors or penetrate outer cable jacket.
7. Connect the watertight connector end of the power cable to the Thor VM2 Quick Mount Smart dock power
connector by aligning the connector pins to the power connector; push down on the watertight connector and
twist it to fasten securely.
8. Secure the power cable to the Thor VM2 using the Strain Relief Cable Clamps (page 4-16).
9. Place Thor VM2 in the Dock (page 4-2)
10. If using the Screen Blanking (page 4-33) feature, install the screen blanking box or switch if not previously
installed.
11. Press the Power Switch (page 3-5) on the back of the Thor VM2 dock.
12. Press the Power Button (page 3-5) on the front of the Thor VM2 to turn on the Thor VM2.
For battery powered vehicles:
The green wire must be connected to the vehicle chassis ground.
For internal combustion engine powered vehicles:
The green wire is connected to the vehicle chassis ground, which can also be battery negative.
