12 Introduction
1.5.3 Reset Button
The reset button executes a hard reset for the MXC-6300.
1.6 Digital I/O Connector
The MXC-6300 controller features an onboard isolated digital I/O
circuit with a 68-pin VHDCI (Very High Density Cable Intercon-
nect) connector on the front panel. The onboard digital I/O card
