External Triggering

Channel-specific external triggering settings are accessed from the cog wheel icon. Select the Channel settings tab.

External triggering is relevant to the control room environment as the protocols involved may be used in the ongoing broadcast process.
External triggering is usually not relevant to a Traffic Department.

At the top-right corner of the External Triggering panel, there is an On/Off (0 : 1) switch. You can configure settings with the devices on or off. When off, the settings will take effect the next time the device is turned on.

The External Triggering settings group comprises:

GPI

GPI is a type of trigger that does not relate directly to a playlist event. A list of commands allows you to define what happens when a playlist is received from an external device.

  • Bits per second: Default is 19200.

  • Port: Select the relevant COM port on the Media Sequencer machine. Default is “--”.

  • Stop bits: Default is 1.

  • Data bits: Default is 8.

  • Parity: Default is None.

  • Box Type: Default is SRC-8.

  • Flow Control: Default is None.

  • Each GPI Action is number DL_n_ or DH_n_, where n is a sequential number, beginning from 0.

  • Under the Commands column, all Viz Commands, editable templates and general actions such as show logo, remove logo, stop active playlist are available as options.

  • Description can be defined freely.

  • IP/Unit/Slave Id: only for SeaLevelMAX.

VDCP

VDCP is one of the protocols used to communicate with external automation systems. Set UI button switch to ON if using the VDCP protocol, otherwise set it to off.

  • Force extended mode for status command: if checked, all IDs longer than 8 characters in "PORT STATUS REQUEST" and "SYS STATUS REQUEST" VDCP commands will be included.

  • Bits per second: Default is 38400.

  • Port: Select the relevant COM port on the Media Sequencer machine.

  • Byte size: Default is 8.

  • Stop bits: Default is 1.

  • Parity: Default is Odd.

    Tip: When setting up the interface to an automation system, start the Media Sequencer in console-mode to see if VDCP commands are properly sent and received as required. In normal production mode is it recommended to run the Media Sequencer as an automatically started service process.

Intelligent Interface

Intelligent Interface is one of the protocols used to communicate with external automation systems.

  • Bits per second: Default is 19200.

  • Port: Select the relevant COM port on the Media Sequencer machine.

  • Encoding: Default is UTF-8.

  • Space Means Empty: Default is No.

TCP

If you want to receive TCP triggers, you must set a port that the Media Sequencer will listen to for that purpose.

  • Port: Enter the port number. This option is disabled when the field is left blank.
