GPI Connector
A General Purpose Interface (GPI) connector (DB-25-F) is provided on the rear panel. Its six
inputs are optically isolated from the Image Server circuitry; individual floating input returns
are provided. +5 volts may be sourced from pins 21 or 22, or provided from an external
source. A current limiting device is provided within the Image Server.
Six general purpose outputs also appear on the GPI connector. These open-collector outputs
may be used as status outputs, or may be used to drive an external LED or control input.
Refer to the connector pin-out table and partial schematic, following.
