Introduction

The MCA-7724 Motion Axis Router reroutes the signals from your motion
controller into separate connectors that connect to different motion
accessories. The router allows you to connect one, two, three, and four axis
drives and accessories to a controller.

Features

The MCA-7724 Motion Axis Router has five 68-pin VHDCI connectors:
the controller connector, connector A, connector B, connector C, and
connector D. Figure 1 shows the five connectors.
