> outputs and digital ins have status LED’s. Sockets are also
> provided to accept 1 dual A/D converter and 1 D/A converter. The
> board also has a second 24 pin socket with its own DB9 connector
> that connects 2 I/O pins to the first 24 pin socket that can be
> used to pass data back and forth for dual processor projects.
> Another nice feature is that both 24 pin sockets have extended
> square pins on the back side of the board for wire wrapping if
> required. The power input will accept 8 to 30 VAC or VDC and the
> onboard switching power supply has enough extra power to supply
> other small 5 volt devices. All electrical connections are made
> with screw type terminal strips.
