The version “11” and “24” scanners head cables are terminated with a male
25-pin D-type connector. To connect the scanner to the host device, may
require a communication cable. The communication cable may include a
connection for a transformer or it may be designed to draw power directly from
the host device. This item can be ordered at the same time scanner is
purchased.
The version “11” and “24” scanners are designed to be used primarily with
IBM® 46XX series of electronic cash registers. It can also be configured to
communicate using the full RS-232 and OCIA protocol.
