Control and Monitoring Features
This section describes the HDC-8223 card-edge status LEDs and display. These LEDs and the
display show status and error conditions relating to the card itself and remote (network)
communications (where applicable). Because these LEDs are part of the card itself and require no
external interface, the LEDs are particularly useful in the event of communications problems with
external devices such as network remote control devices. Refer to
Figure 3.1 for the location of
the LEDs.
