Version A15 Pin Assignments for the Mil spec Connector

Each TECH 8 scanner has a 19-pin male Mil spec connector that is found on the side of the unit. To connect the scanner to the host device, use a communication cable with a female Mil spec connector. The communication cable may include a power transformer or it may be designed to draw power directly from the host device. This item can be ordered when the scanner is purchased.

The following is a list of pin assignments for Version A15 scanners. The communication protocol for Version A15 is light pen emulation. The pin numbers are impressed on the male Mil spec connector. For easier reference, refer to Figure 5 for pin locations.
