Version A1 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 A1 scanners. The communication protocols
for Version A1 are RS-232 and OCIA. The pin numbers are impressed on the male Mil spec
connector. For easier reference, refer to Figure 4 for pin locations.
