Follow these guidelines:
Set configuration plug E15 on the absolute encoder module to the right
position for increasing position.
Signal common (pin X) and ground (pin W) are internally connected on
the encoder.
The encoder counts up in a clockwise direction when you connect pin J
instead of pin H.
Leave pins V and Q unconnected.
Jumper the unused most-significant-bit input terminals.
