JP2: LED Header
This header provides access to each of the monitoring LEDs. These pins can be connected
with a jumper wire to any of the JP1 pins to monitor the signal level with the corresponding
LED. When a high is present, the LED illuminates. Test LEDs by using a jumper to any of
the JP4 pull-up pins. Each LED has a unique color to facilitate identifying the LEDs that are
on.

JP2 Pin # Connects To:
1 LED1 – green
2 LED2 – yellow
3 LED3 – orange
4 LED4 – red
JP3: Input Switch Header
This header provides access to each of the two input control switches. These pins can be
connected with a jumper wire to any of the JP1 pins to control the signal level with the
corresponding switch. When a switch is in the center position, it is off. This allows a 1K pull-
up resistor to create a high on the corresponding pin. When a switch is turned on, it connects
the corresponding pin to ground. Each switch has a latched-on down position and a
momentary-on up position
