Status Light

Three Status LEDs exist on the SLP module. The top LED (see figure above) indicates the
condition of the module. It will blink ON and OFF while the module is booting up, then will stay
ON during normal operation. The bottom two LEDs are not used and will always be off.

Pushbutton

See Caution note below before operating the pushbutton. One pushbutton is provided. Pushing
and holding the pushbutton for less than 5 seconds will simply restart the user application program
if it was configured to "auto-run" at power up. Pushing and holding for more than 5 seconds will
reinitialize the module and require that the user application program be reloaded.
