PCM-QUAD02 User's Guide
The incremental encoders connect to each channel through either a screw terminal board or a user-configurable,
non-terminated cable. The signals provided are (per channel):
Phase A+, A–
Phase B+, A–
Index+, Index–
+5V and GND (optional power for 5V encoders; not to exceed 400 mA peak)
