Controlling the Stage
The stage can be controlled in three ways; via the handset, by the Elliptec software running on a PC, or by writing a custom
application using the messages described in the communications protocol document. Homing and Jogging functionality can also
be accessed by applying voltages to the digital lines on Connector J1. The modes of control are described in the following
sections.
In all modes, when the unit is mounted in the recommended orientation, Forward moves the stage to the right and backward
moves to the left as shown in Figure 2.
4.2.1 Hand-held Controller
Caution
On power up the stage will move while the unit checks the sensors and then searches for the home position.
The ELL10K Evaluation Kit also contains a hand-held controller, which features two buttons (marked FW and BW) that allow
control of the stage position. The handset also provides for connection to the host PC and to the external 5V power supply.
The external PSU connector allows the stage to be used in the absence of a PC, with control being achieved via the handset
buttons.
LED1 (green) is lit when power is applied to the unit. LED2 (red) is lit when the device being driven is in motion.
