3.7 Diagnostic LED Header
The 914-HDE card includes a 10-pin header capable of driving 8 LEDs. This is useful for LED integration into
an enclosure. Each LED pin is driven low to turn on an LED, and includes a 267 ohm resistor in series to limit
the current draw. Maximum current draw is 8 mA.
This header may optionally become an input via the diagnostic GUI with firmware revisions greater than B1.
The LED header is FCI P/N 20021521-00010T1LF, and the mating part is FCI P/N 20021444-00010T1LF. This
can be used with most 0
.050” (1.27mm) spacing ribbon cables.
