Page 8 DTN000522-D02
4.2.1 Hand-held Controller
Caution
On power up the rotator will move while the unit checks the sensors and then searches for the home position.
The hand-held controller supplied with the ELL14K Evaluation Kit features two buttons (marked FW and BW) that allow control
of the rotator position. The handset also provides for connection to the host PC and to the external 5V power supply. The external
PSU connector allows the rotator 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.
