For accuracy in your application, type these conversion factors as “double” (avoid using the
“float” type as it lacks precision with large values). When converting to microsteps, type the
result as a 32-bit “long”, “signed long”, or “I32” integer. When converting to microns, type
the result as “double” (64-bit double-precision floating-point values).

NOTE: Origin is a physical position of travel that defines the center of the absolute position coordinate system (i.e., absolute
position 0).
Physical Positions: BOT (Beginning Of Travel), COT (Center Of Travel), & EOT (End Of Travel).
In the TRIO MP-145 Series, the Origin is fixed at BOT.
NOTE: Travel length of each axis is automatically determined by end-of-travel sensor.

Commands
4.6.1
Get Active Device & Firmware Version (‘K’) Command
This command is used to obtain the current-active device attached to the controller. The data
returned is four bytes, the first of which is the device number (1 (MANIPULATOR A) or 2
(MANIPULATOR B), followed by the major version number, minor version number, and the
completion indicator.
