5.1.5 914-VDX Diagnostic LED Header

The 914-VDX 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.
Serial data activity header pins can be configured for Tx (Transmit Activity), Rx (Receive Activity), or both
(Default) via the diagnostic GUI.
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.
