Control Upstream Router: This check-box should be ticked if the EMC is required to control the
upstream router. If the EMC is set to A/B Mode (see 4.3.7), then this check box
should be left unchecked. This would mean either automation or the operator is
responsible for switching the proper sources to the destinations that are feeding
the EMC.
Port Number: This combo-box selects the port that is controlling the upstream router, the correct
protocol and port parameters should be configured for the upstream router in
section 4.9.
Switch Delay: Normally a transition will be completed immediately when a switch update has
been received by the EMC from the upstream router. The Switch Delay settings
tells the EMC how long to wait for the update before the transition is completed,
i.e. if the update hasn’t been received only wait this long then finish the transition.
If the “Force Delay” checkbox is ticked then this forces the Switch Delay to take
effect regardless of the switch update being received from the upstream router.
IMPORTANT: If a port other than Q-
LINK 2 is configured to control the upstream
router then Q-LI NK 2 MUST be configured to ‘No Protocol’ in the Ports Tab.
4.10.1. Upstream Destinations
This section allows the destination number of the program, preset and any additional bus fed from an
upstream router to be defined. The EMC allows the 14 main video inputs to be controlled from the
upstream router. In addition EMC allows four additional spare router outputs to be controlled from EMC
control panels for purposes such as monitoring, quality control or routing the PGM and CLEAN Bypass
Inputs.
4.10.1.1. Destination
This number relates to the destination needed to switch the upstream router. Enter the special value of
“9999” to disable control, i.e. no upstream destination for this input.
4.10.1.2. Video Level/s
This determines the levels to switch in order to control the video of the upstream router. Select or de-
select levels as required e.g. for an SDI only installation just select level 1.
4.10.1.3. Audio Levels
This determines the levels to switch in order to control the audio of the upstream router. For an SDI
router with embedded audio select level 1, otherwise select level 2 and/or 3 for AES.
4.10.1.4. RS422 Level
This byte determines the level to switch in order to control the RS422 of the upstream router. This is only
used if machine control is required for preset and program buses.
