B. Cable Installation
Printek provides a single 9-pin D-connector that plugs into the back of the VP420 printer. This
connection provides for both data communication and power to the printer. The cable has a
USB-A connection to plug into the host. The cable has two unterminated power wires coming
out of the connector. The positive cable is marked with red.
The Red labeled wire in the power cable may be connected to a 9-32 VDC source and the Black
wire is to be connected to vehicle ground. The printer’s power input is internally fused, but may
be connected to a fused circuit that is capable of providing at least 5A.
