Absolute Encoder Interface Board Section 8-3
LED Indicators
8-3-6 Pin Arrangement of Connectors CN1 and CN2
CN1 and CN2 have identical pin arrangements.
Note 1. Refer to Appendix A Preparing Cables for Inner Boards for information
about using a compatible connector (XM2D-1501 Socket with XM2S-1511
Hood) to construct a cable. When connecting to an absolute encoder man-
ufactured by OMRON, the E69-DC5 Absolute Encoder Interface Board
Connecting Cable (described below) can be used.
2. Only absolute encoders that produce binary gray code outputs can be
used.
