Appendix 3 GPI / GPO Connections
The HS-2850 can control external recorder/playback devices like the HDR-60 and HDR-70 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 HS-2850.
Contact closure between the Outer and Inner contacts on the jack plug will trigger a user
selected event. Power is supplied by the HS-2850 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 HS-2850
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.
