Supported Commands
The switcher can be controlled from a remote device or computer via GV Grass Valley
®
GVG100 commands.
These commands can either be sent to the switcher over a serial or Telnet connection.
Sending GVG100 LUA Commands to the Switcher
The switcher accepts direct injection of GVG100 commands using LUA via a Telnet connection. This allows you
to perform various functions such as querying the switcher for the state of buttons, or sending commands to
the switcher, such as transitioning a key.

GVG100 Command Modes
The switcher supports two modes of operation, a Legacy mode for basic GVG100 commands, and a Ross mode
for additional Ross-specific extensions to the protocol.
• Legacy Mode — allows basic control over a single ME (ME 1) and the first two keyers (Key 1 and Key 2) on
that ME
• Ross Mode — allows advanced control over multiple MEs, keyers, and aux buses.
