Thor VM1A Vehicle-Mounted Computer 81
Power Supply Connector
• Power is supplied to the VM1A through the power connector. Additionally, this
assembly provides a connection point for the vehicle’s chassis ground to be
connected internally to the conductive chassis of the computer.
• The computer’s internal power supply can accept DC input voltages in the range
of 10 to 60 Volts DC when using the VM1D standard dock or VM3D enhanced
dock. The VMXD dock DC input voltage is 13.2VDC from the AC/DC power
supply.
• See
Power Supply Connector for connector pinout detail. See Connect Power for
more information on connecting power to the VM1A.
