Versions “11” and “24” Pin Assignments for RS-485

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.

The following is a list of the pin assignments. The pin numbers are impressed on the head cable’s connector.
