More details

JOyVerride 20i‑BMD interface is desinged to operate in conjucntion with Blackmagic Design Videohub series routers, directly via Ethernet. Its function is to provide momentary switching of a video router input, when a contact closure occurs on its assigned camera RCP joystick – that is, when the camera operator keeps pressing on it. When the joystick is released, the contact opens and the video router returns to the previously selected input.

Currently, only momentary switching is provided, latching action is not implemented. This might be considered at a later stage, in case there will be interest thereon.

The interface has a number of 20 GPI inputs, such that a maximum of 20 contact closures from 20 joystick camera RCPs can be connected to it.

Each GPI input can be configured to address a particular video router output. In this way, an arbitrary number of video router inputs can be grouped to serve an arbitrary number of video router outputs – useful, for example, when a single video router is used by two or more camera operators, each one operating a group of camera RCPs on their own video control monitor.

All GPI inputs are floating, isolated by optocouplers and share a floating common 0V rail to which each contact must be closed.

The connection from the interface to the video router itself is done through the local Ethernet network. No additional equipment is required during normal operation.

The interface is delivered with the DHCP mode turned ON, unless otherwise requested.

Configuration is platform independent and can be done by more than one single method:

  • (valid for: credential configuration, network parameters; also GPI inputs assign)
    via serial remote session, by running a serial terminal on a PC connected through the dedicated USB Mini-B terminal connection and then using typical Linux commands.
    - or -

  • (valid for: credential configuration, network parameters; also GPI inputs assign)
    via SSH remote session, by running a SSH terminal on a PC connected through the network and then using typical Linux commands;
    - or -

  • (valid for: credential configuration, network parameters; also GPI inputs assign)
    directly from the interface, by connecting to it a monitor with HDMI input and a USB keyboard and then using the native Linux terminal & typical Linux commands;
    - or -

  • (valid for: basic network parameters, GPI inputs assign)
    via network, using the built-in web page that can be accessed from any web browser that is connected to the same network;

    Note: planned feature, not implemented at the time of this writing.

Setting up the GPI inputs via terminal mode, either local or remote, means editing a plain text configuration file.

Details for each configuration method will be described in the JOyVerride 20i-BMD user manual.
