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 3 for pin locations.
