LED Lines

The EM2000 has four LED control lines — SG, SR, EG, and EY. All lines have the same internal structure and LEDs should be connected to these lines as shown in the schematic diagram below. The maximum load for each line is 20mA.

Further information on status LEDs can be found in Status LEDs.

Your Tibbo BASIC/C application can control the red and green status LEDs, as well as up to four externally connected LED pairs through the pat. object.

Note that the EM2000 also features three onboard LEDs: green and red status LEDs, plus one yellow Ethernet link LED.
