GPI / GPO Connections

The SE-2800 can control external recorder/playback devices like the HDR-45 and HDR-55 via a simple contact closure
GPI / GPO switch.
The GPI interface is a 3.5mm Jack Socket which is situated on the rear panel of the SE-2800. Contact closure between
the Outer and Inner contacts on the jack plug will trigger a user selected event. Power is supplied by the SE-2800 and is
less than 5V DC.
This GPI socket can also be used as a GPO socket to trigger record or playback events with other equipment such as
the Datavideo HDR-70 recorder.
SAFETY FIRST The cabling required needs to be designed specifically to connect the SE-2800 to the chosen record or
playback device as they are not all the same. The cabling required can be made by yourself or a competent technician.
Please speak with your Dealer or local Datavideo office to get further help and advice.
