B ALTERNATIVE CONNECTIONS FOR ETHERNET MODELS
The connector pinouts and notes given in this appendix are for custom cabling applications.
POWER, COM AND I/O CONNECTOR
The scanner is equipped with an M12 17-pin male connector for connection to the power
supply, serial interfaces and input/output signals. The details of the connector pins are
indicated in the following table:
