The "<cr>" is a carriage return character ( <Enter> key on most keyboards). Command
characters are in a rectangle like this:
C I3M400<cr> C I3M400<cr>

A diagram of the resultant motion of a screw driven linear actuator is included showing
start/end points, direction and commands. A letter over a point on the diagram represents
the function occurring at that point. A “P” is a pause command, “U” user I/O command,
and a “Z” is a motor 3 Index. Numbers shown in the diagrams represent Loop count
values.
The following examples can be keyed into the VXM with a terminal program like
HyperTerminal in Microsoft Windows, or the Velmex COSMOS software. Another method
to send commands is with commercially available languages such as VisualBASIC, C,
LabVIEW, etc.
