SKaarhoj ETH-GPI Link

Ethernet to General Purpose Interface with UniSketch OS.

Connects relays and opto-isolated inputs with network events. Use it to switch or route a source, start/stop recording, turn on tally lamps etc. 2x8 Inputs/Outputs with option for additional 2x8 I/O.

Dual GPIO

16 channels input. 16 channels output

• 2 x DB25 Connector Configuration
• 16 GPO
• 16 GPI
• UniSketch web interface for extensive configuration

GPIO Control Made Easy

Setting up an I/O device have never been this flexible. Connect and control anything from your tally lamps, trigger ATEM switcher routines, control a HyperDeck, change Scopes on a SmartScope Duo and route inputs/outputs on a VideoHub. Defining parameters – single or multiple - for inputs/outputs is extremely fast, thanks to the drop-down menu structure in the web interface. Connect and control up to 8 devices at the same time!

Broadcast I/O

Easy control or integration with existing systems

The GPIO controller let you control anything from your tally lamps, a foot switch over ethernet or integration with existing systems such as CCUs, video routing and other video switchers or video infrastructure units. There are almost endless possibilities.

The general-purpose I/O controllers offer 8/16 inputs and 8/16 outputs, all electrically separated with quality relays and optocouplers. GPO is implemented with relays shorting to GND. GPI implemented with optical isolators shorted to GND.

The DB25 connector configuration is similar to the Blackmagic Design GPI & Tally Interface. If you fancy a breakout board for the DB25 connector with Phoenix connectors then have a look at the Breakout Board.

Device Settings

The ETH-GPI Link runs UniSketch OS which allows you to configure the device for multiple hardware devices such as the ATEM Switcher, HyperDeck, SmartScopes, VideoHubs, AJA KUMO Routers, vMix and more - see the entire list. You can even configure the unit to control multiple hardware devices at the same time! The microprocessor (SKAARDUINO Due) inside the ETH-GPI Link allows connections to a maximum number of 8 devices.

Web Interface

Configure GPI & GPO

When entering the web interface of the UniSketch this is the overview you are presented with (for the ETH-GPI Link). By pressing on either of the In/Out pins the menu will jump to that particular input/output setting. Here you can define behavior for almost any of the ATEM parameters, control HyperDeck, SmartScope and VideoHub and more hardware devices - see the overview on Device Cores.

When you select an ATEM parameter to control, a number of options will appear such as selecting 1ME or 2ME, particular sources and default, Hold Down, Toggle or Cycle behaviour.
