LED Control
The IB1004 works with a standard LB1001 board and controls the LEDs through eight general-purpose I/O (GPIO) lines of the EM1000 module (installed on the NB10x0 network board). To turn on an LED, set the corresponding line LOW. Remember to configure all LED control lines as outputs.
For all LED control lines:
- HIGH (or input*) — LED off
- LOW — LED on
