The mainboard can drive an 8
Ω
external speaker at 0.5 watts. If
there is no external speaker, the SBC-776 provides an onboard
buzzer as an alternative.
LED interface
The front panel LED indicator for hard disk access is an active low
signal (24 mA sink rate).
Next you may want to install external switches to monitor and
control the mainboard. These features are completely optional —
install them only if you need them. The front panel connector (JP6)
is an 16-pin male, dual in-line header and provides connections for
a speaker, hard disk access indicator and an input switch for
resetting the card.
