Description and Configuration
The MXH multiplier board connects between the encoder and the appropriate axis
controller. Refer to Figure 1-2 for an example configuration. This connection does not
affect Hall effect or limit signals; instead, it is a simple add-in that uses mostly standard
cables.

Axis Controller Device

The multiplier board accepts 1 V peak-to-peak voltage input signals. The outputs are
square wave, RS-422 TTL compatible signals. The input marker signal is expected to be
active high and located at the 255° point of the 360° electrical cycle. The plots illustrated
in Figure 1-3 show typical input and output signals (cosine, sine, and marker).
