Additional OEM Interface Signals

The output LED signals ORLED-, GRLED- and YELED- represent the state of the LEDs on the module. Logic 0 indicates the LED is on, and Logic 1 indicates the LED is off. Buffers are recommended if LEDs are to be driven on the end-user side.

The SWITCH signal is connected to a momentary pushbutton switch on the evaluation daughtercard and is in the normally open position. Depressing the switch causes a short to ground. A 4.7 K-ohm pull-up resistor to +3.3 VDC is connected. The module’s processor monitors this signal. The end-user can drive or use open-collector to this signal to either logic level or can monitor this signal as an input.
