Version "1" Pin Assignments for RS-232, OCIA, and Bi-direc­
tional RS-232
Each TECH 7 scanner has a 19-pin male Mil spec connector that is
located 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 supply or it may be
designed to draw power directly from the host device. This item can
be ordered when the scanner is purchased.
The Version "1" scanner is designed to be used for RS-232, OCIA,
and RS-232 with limited receiving capabilities.
The following is a list of pin assignments. The pin numbers are
impressed on the male Mil spec connector. For easier reference, refer
to Figure 9 for pin locations.
