OSCA-I8 8-Channel OSC GPI Input

The OSCA-I8 converts simple GPO dry contact closure like remote buttons or triggers into powerful OSC network commands. The 8 opto-isolated inputs also allow connection to  low volt logic circuits. Applications range from interfacing third party devices like mixing consoles, automation controllers, motion sensors or switches and buttons into OSC commands freely dictated by the user.

The OSCA-I8 has eight individual input channels allowing eight separate GPO to be connected simultaneously. Multiple OSCA-I8  units can be deployed on a single OSC network, allowing complex and creative control scenarios to be achieved in a robust and coherent fashion.

The OSCA-I8 also allows direct, simple connection to the industry standard 8 button REM8D -  ideal for controlling QLab and other OSC devices.

The OSCA-I8 is incredibly easy to program - simply plug it into your laptop, type in the IP address and a simple but powerful user interface takes you through all the steps. If the Osca OSC network is connected to the internet, remote programming and triggering is possible via VPN, together with system updates and future upgrades. Fully compatible with all 3rd party OSC commands and the Nemesis OSCA  range.

The OSCA-I8 features configuration backup and restore, so you never have to remember your settings.

After purchase OSCA-I8 can be upgraded to Pro Spec, adding additional power and functionality for the most demanding show control applications (see below).
