1. Introduction
DMX-K-SA is an all-in-one integrated motor package that combines all the motion
components in to one convenient package.
Communication to the DMX-K-SA can be established over RS-232 or RS-485. It is also
possible to download a stand-alone program to the device and have it run independent of
a host.
Sample source code is available to aid you in your software development.
