Values can be set at any time by command (e.g. in a macro).
PIMikroMove™
sends the commands to set appropriate values automatically when a known stage
is connected.
MMCRun
does the same when a class of stage is selected on the
start screen.
In many cases even the values provided for the stage (by the software or from the
stage User Manual) will not be optimum for your application.
If customized start-up values for any parameters are required, the autostart macro
of the controller (Macro #0) can be used to set them. It is not possible to store
modified parameters as new power-up defaults directly.

Cable Connections
The motor control signals are all on the 15-pin sub-D “DC Motor” connector;
they include the motor control lines (outputs) and the encoder and limit
switch signals (inputs). This connector is compatible with all PI stages
having DC motors and current voice coil drives. Stages with detachable
cables come with the C-815.38 Motor Cable for connection to the controller.
Stepper motor drives use the same connector but are not compatible.
Permanent damage can occur if stage and controller types are not
compatible.
The host PC connects to one of the Mercury™ Class controllers on the
network via RS-232 or USB. The “RS-232 OUT” connector of that controller
can be used to connect an additional controller with a straight-through
networking cable (order number C-862.CN). Up to 16 Mercurys™ can be
