via its on-board connectors, such as 2
nd
optional VGA output, remote on/off control, LED
status output, parallel port and etc. In this section, we’ll illustrate these internal I/O
functions.
2.3.1 Status LED Output & Reset Control
For an application which places Nuvo-2000+ inside a cabinet, it’s useful to output the
system status to external LED indicators so that users can check how the system’s running.
Nuvo-2000+ provides a 2x6, 2.0mm pitch pin header to output system status such as power,
HDD, CF, LAN, watchdog timer, and control system reset.
The status LED output has a built-in series-resistor and provides 10mA current to directly
drive the external LED indicators. System reset control is also provided so you can use an
external non-latched switch to reset the system. The following table describes the pin
definition of the status LED output.
