GPI Pinouts
General Purpose Interface (GPI) pinouts are shown below. The GPI IN
(
Figure 14) is a 9-pin D male connector and the GPI OUT (Figure 15) is a 15-
pin D male connector.
GPI Out Encore Panel Server State Indication
GPI Out Relay 4 can be used to remotely determine the Encore Panel
Server/RCL Server Supervisor/Subordinate state. Relay 4 pin 14 closes to
pin 9 (and opens pin
4 to pin 9) to indicate the Supervisory state.
For example, you can wire each SCB’s pin 14 to an LED in series with pin 9
and a power supply. When these SCBs are run as redundant pairs, the LED
of the SCB acting as Supervisor will illuminate, and that LED will go dark
when that SCB is Subordinate. Taking the Supervisor SCB of a redundant
pair off line using the Encore Panel Server application will make both LEDs
immediately change to the opposite illumination state (the other SCB
becomes Supervisor).

Withdrawing an SCB from Frame disconnects pins 1-4 and 11-14.
After an SCB is powered up and initialized, pins 11-13 will close with
respect to pins 6-8, and pin 14 reports Supervisor (closed) or Subordinate
(open) in respect to pin 9.
