VMXD Enhanced Dock with Thor VX8/Thor VX9 Power Cable
This dock is recommended for use when replacing an existing Thor VX8 or Thor VX9 where screen blanking is
used. This dock eliminates the need for wiring changes by enabling the existing VX8/VX9 power cable and
screen blanking box to be used when the VX8/VX9 is replaced by a Thor VM3 computer. These instructions
are for this dock model only!
The Ignition Control feature is not available when this dock is used.
The external DC/DC converter previously used with the Thor VX8 or Thor VX9 must be left in place to pro-
vide ground isolation.
Connecting the dock power input directly to vehicle power could result in a safety hazard or equipment damage.
The cable shielding must be connected to chassis ground.
Consult the instructions later in this section for the respective power supply type.
COM1 is used for screen blanking (via the power cable connector) and is unavailable when the screen blanking
box is attached. When a screen blanking box is attached, any external serial device such as a scanner, must be
connected to the COM2 port on the dock. If a screen blanking box is not connected via the power cable, the
COM1 port on the dock is available for a serial device connection.
Determine the type of power supply used with the previous Thor VX8 or Thor VX9 installation:
• DC/DC Power Supply with Screws on Top of Lid
• DC/DC Power Supply with Screws on Side of Lid
