Notes
1. Power Fail Sense# is intended for input and sends a NMI to
the processor when voltage falls below 0.8V. The signal is
filtered for noise.
2. +3.3V, +5V, −12V, −5V, and GND should only be used for
low-power applications.
On MBX821 models, a 24-pin dual-row header supplies the interface
between the MBX821's LCD controller and the panel. The pin
assignments for the LCD connector are listed in the following table.
