Hello,

I would like to ask you guys, if I want to connect GPI (for EPS purpose) to the doremi (to triget the lamp off macro etc), in what form the signal from EPS should be? Is it 5V as is used on GPO?

Thanks for your answers

The GPIs are optocoupler inputs, and include current limiting resistors and reverse polarity protection for input voltages between 5 and 12 Volts.

The Doremi FieldInstallerManual v1.5 shows schematics for GPI and GPO ports and suggested usage. If you don't find this document, get back to me.
