1. Use 3-pair, #22 gauge individually twisted and shielded pair, Belden 9504 or equivalent.
2. Use 1-pair, #18 gauge twisted and shielded cable.
3. Encoders must have +5V compatible differential line drive outputs on channels A, B and Z. (DS8830 or equivalent - Allen-Bradley 845H).
4. +15V from encoder power source - connect encoder return to 0V user power (DC common) at the power supply sources.
