LC1000 LED Board Cable

Top  Previous  Next

The LB100x LED boards connect to the network board ("NB") or interface board ("IB") via the LC1000 cable. There is a connector on the LB100x, as well as "NB" and "IB" boards. Connector pin assignment is shown below. LED numbers correspond to the numbers shown on the mechanical drawing of the LB100x. Pin #1 position of the connector is also shown on 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, the 0 Ohm resistor is used. Documentation for specific LB100x boards provides necessary info.
