GPIO pinouts

The following GPIO pinouts are on DB-9 (the control connector). Each control pinout is open-
collector controlled.
 Control 0: DB-9 pin 1 (shows power supply failure status).
Control 1: DB-9 pin 2 (internal use only).

 Control 2: DB-9 pin 8 (internal use only).
Control 3: DB-9 pin 6 (internal use only).

 Password reset: DB-9 pin 9 (must be connected to ground for a reset condition).
 Ground: DB-9 pin 5.
 DB-9 pins 3, 4, and 7 are not connected.
The GPIO has a tally output connection on the DB-9 connector, controlled by software, and can be
used to sink DC current to signal a condition or event. See the functional diagram below:
Users must be careful not to exceed the maximum electrical specification for the GPIO of 20V d.c.
and 0.75 A. For example, using a 12V d.c. power source, the minimal load resistance should be 16
Ohms as per Ohm law.
