Running an Exposure from the Controller

Press

All LEDs are in either count up or countdown mode:
If the arrow in the status bar is pointing up, the unit is in count up mode. Each UV LED Head will be on until you
press
Start/Stop
again or one of the other input control signals is toggled.
If the arrow in the status bar is pointing down, the unit is in countdown mode. Each UV LED Head will be on for the
duration of the set timer for that channel on the Main Control Panel screen.

Using the PC Interface with USB Connection
The LX500 can be commanded via a virtual RS-232 serial port. The serial port communication settings are not
adhered to and instead communication occurs at the USB 2.0 speed of 12Mbps. All serial commands are available
in an SDK which is available upon request.
The LX500 complies with the S2000 command set. Use the StepCure screen to select which LEDs will respond to
this command set. To do this, the first row is the LED #, set the last row to PC. Refer to
Section 6.4,
“Defining
Exposure Parameters”.
