Encoder Output Connector
The encoder output connector is a dual use connector. It can be used for either Encoder Output
or for Hall Effect Input. Use DIP Switch #3, position 4, to select desired function.

Encoder Output to
External Devices
The encoder output can be used to send information to an external device. In multi-axis
applications, for example, with APEX615ns running in following mode, you can connect the
encoder output from the master unit to the encoder input of the slave unit, as shown in the
next drawing. See the Programmer's Guide for details.
