Terminal assignment
Interface Type of connection Cable (isolate unused wires individually before initial start-up)
Signal: 0 V +V C+ C- D+ D-
2 1, 2, A, B
Cable colour: WH BN GN YE GY PK
+V : Encoder power supply +V DC
0 V : Encoder power supply ground GND (0 V)
C+, C- : Clock signal
D+, D- : Data signal

1) The power supply at the encoder input must not be less than 4.75 V DC (5 V DC - 5 %).
2) Short circuit to 0 V or to output, only one channel at a time, power supply correctly applied.
