NK-VRC User Guide (v05) Operating the NK-VRC • 37
Operating the NK-VRC
The NK-VRC operates transparently between all remote control panels, controlling devices (NK-GPI, NK-JBX),
and the routing switcher system. There are four LEDs and a reset port on the front panel of the NK-VRC.
General
Remote control panels are used to switch virtual sources and destinations, therefore, the keys on the remote control
panels should reflect this virtual context.
If resource management is in use, the panels with a display will indicate when a resource is in use. Additionally,
control panels can be configured to have a resource de-allocate button to manually release a resource that is in use.
For More Information on...
• control panels, refer to the user guide of the respective control panel.
Resource and Panel Priorities
Each resource has a priority assigned to it. This can be used to reserve it for high priority use.
Similarly, each panel or control device has a priority assigned to it that determines which resources can be accessed
by that panel/device.
Resources and control panels can be assigned a priority from 1 to 8, where 1 is the highest priority and 8 is the
lowest priority. If priorities are not required, set all the priority levels to be the same. The default is 8.
In order for a control panel to be able to access a resource, it must have a priority higher than, or equal to, the
resource priority.
A resource can only be de-allocated by the control panel that originally allocated the resource, or by another panel
with a higher priority. The NK-VRC de-allocate function in DashBoard has the capability to de-allocate any
resource regardless of which panel allocated it originally.
LED Indicators
The front panel of the NK-VRC has four LEDs. During startup, these LEDs flash five times to show that they are
functional and to indicate that the NK-VRC is initializing.
During normal operation, the LEDs indicate the flow of requests and responses between the remote control panel
and the routing switcher.

LED Function
A Shows that a virtual switch request has been received at the NK-VRC from a remote
control panel.
B Shows that a physical switch request has been sent from the NK-VRC to a routing
switcher.
C Shows that a physical switch response has been received at the NK-VRC from a routing
switcher.
D Shows that a virtual switch response has been sent from the NK-VRC to a remote control
panel.
