GPIO Connectors
General purpose control inputs (GPI) may be applied to the GPI ports, which are DB-25-F
connectors. These inputs are optically isolated from the Image Server circuitry; individual floating
returns are provided. +5 volts may be sourced from pins 21 or 22, or provided from an external
source. Current limiting devices are provided within the ImageServer.
General purpose status outputs also appear on the GPIO connector. Open-collector outputs are
provided as status outputs, and may be used to drive an external LED or control input.
See page 120 for more information on GPIO interfacing.
