The CANbus/Audio connector is a D-15 male connec-
tor located on the back of the Smart Dock.
The connector supports a headset adapter cable or a
CANbus cable. The Thor VM3 does not support con-
necting audio and CANbus simultaneously.
See CANbus / Audio Connector (page 9-11) for con-
nector pinout detail.
A headset cable attaches to the CANbus / Audio con-
nector and provides a quick connect connection for a
headset. See Connect Headset Cable (page 4-42) for
more information.
The CANbus Y cable has a 9 pin F SAE J1939
(Deutsch) and 9 pin M SAE J1939 (Deutsch) connec-
tor. See Connect CANbus Cable (page 4-44) for more
information.
The CANbus interface is a virtual COM port. This port
can be accessed using standard Windows API calls.

Power is supplied to the Thor VM3 through the power connector. Addi-
tionally this assembly provides a connection point for the vehicle’s chas-
sis ground to be connected internally to the conductive chassis of the
computer.
The Thor VM3 internal power supply can accept DC input voltages in
the range of 10 to 60 Volts DC.
See Power Supply Connector (page 9-6) for connector pinout detail.
See Connect Power (page 4-17) for more information on connecting
power to the Thor VM3.
The Thor VM3 is equipped with an 802.11 radio and can be ordered with internal
antennas, external antennas or external remote mount antennas. When the Thor VM3
is ordered with internal antennas, the external antenna connectors are not used. GPS
and WWAN are optional on the Thor VM3 and require external remote mount anten-
nas.
