2.3 Internal I/O Functions
In addition to I/O connectors on the front/back panel, POC-100 provides other useful
features via its on-board connectors, such as SATA port, mSATA socket, mini-PCIe socket,
LVDS, optional COM ports, remote on/off control, LED status output and etc. In this section,
we’ll illustrate these internal I/O functions.
Status LED Output
For an application which places POC-100 inside a cabinet, it’s useful to output the system
status to external LED indicators so users can check how the system’s running. POC-100
provides a 2x8 pins, 2.0mm pitch box header to output system status such as power, HDD
and watchdog timer.
The status LED output has a built-in series-resistor and provides 10mA current to directly
drive the external LED indicators. The following table describes the pin definition of the
status LED output.
