914-HDE 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 per LED pin is 8 mA.
This header may optionally become an input via the diagnostic GUI with firmware revisions greater than B1.
The LED header J9 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.
