The encoder must be wired to a 9 pin 'D' male plug, using good quality multi-
core/conductor screened/shielded cable, according to the diagram shown in
Error!
Reference source not found. . Although there is a Screen/Shield pin, the cable
screen/shield should be connected to the connector shell. The pin is for use with not
metallic connector shells (not recommended). If the encoder does not have an index (Z)
output, leave the
index and !index unconnected.

The maximum input frequency the encoders can normally accept is 8 million quadrature counts per
second. This equates to a maximum frequency for the
chA and chB signals of 2MHz. However this
maximum is limited to short cables, the following table shows recommended length vs. frequency for
differential signals.
