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.
