Configuring GV I/O Time Delay channels

Install the GVIO-SW-OPT-TD license before configuring the recorder and player channels.
Stop AppCenter if it is running. It is not advised to configure channels while AppCenter is running as any changes to the configuration requires a restart of the AppCenter.

The Time Delay option requires a minimum of two channels on a GV I/O, one for the record and one for the time delayed playout.

This provides the ability to set up a loop record on one channel and have a time delay for playout set on one or more of the other available channels.

Click on the Channels tab, and select the specific GV I/O channel that you want to configure.
Click the Configure button.

The Channel Configuration page displays.

Click on the drop-down list and select the appropriate option for each setting:

Available input signals are in the list below: Unassigned - The channel input is set to this initial setting by default. No other settings are configurable when this option is selected. Note: Changing a channel's I/O configuration to Unassigned will set channel configuration information to a default state and release any SabreTooth licenses associated with the channel. SDI - Configures the channel to use SDI input. Requires the GVIO-HW-CORVID88 hardware configuration and GVIO-SVR-SDI license per channel. SMPTE 2110 - Configures the channel to use 10/25GigE SFP input and allows for SDP file import. Requires the GVIO-HW-CX6 hardware configuration and GVIO-SVR-IP license per channel. NDI - Configures the channel to use NDI input. Requires the GVIO-SW-NDI-CH license per channel, with maximum of 4 channels per GV I/O server.
