LC1000 LED Board Cable
The LB100x LED boards connect to NB10x0 network boards ("NB") or IB100x interface boards ("IB") via the LC1000 cable. There is a connector on LB100x, "NB," and "IB" boards. The connector pin assignment is shown below. LED numbers correspond to the numbers shown in the mechanical drawing of the LB100x. The pin #1 position of the connector is also shown in the drawing.

Important note: For correct operation, a current-limiting resistor must be connected in series with each LED. Most I/O lines of the EM1000 installed on the NB1000 network board already have a current-limiting resistor, so the resistor onboard the IB100x is not always necessary. In this case, a 0Ω resistor is used. The documentation for specific LB100x boards provides the necessary info.
