Configuring Control Panel/Device Priorities
All control panels and devices (panels and interfaces through the NK-IPS) have an assigned priority. This dictates
the priority of requests if there are a limited number of resources available.
Every T-Bus device, including the NK-IPS, requires a unique address. Addresses range from 1 to 255. Default
addresses are set to the last two digits of the serial number, plus 100.
The Priorities Tab
Figure 4.18 Priorities tab
There are eight priority levels. Level 1 has the highest priority and level 8 has the lowest. The default level is 8.
Priority assignment is based on the T-Bus address of each panel or device.
To assign a priority:
1. In DashBoard, open the NK-VRC device tab.
2. Select the Priorities tab.
3. In the Priority field, enter a priority value from 1 to 8 for each address corresponding to a device on the T-Bus.
4. Click Send Configuration (see “Sending the Configuration to a Device” on page 4–4).
Setting Up Machine Control
If the routing switcher system uses a machine control routing switcher to provide reciprocal switching of RS-422
signals, the remote control panels and NK-VRC need to be set up to handle these switches. Machine control must be
enabled in the remote control panels and the NK-VRC, and the router level used for machine control must match
across all devices.
To set up machine control in the NK-VRC:
1. In DashBoard, open the NK-VRC device tab.
2. In the Physical Map tab, use the MC Level list to select the value that corresponds to the level set in the
machine control routing switcher. The default level is 8.
3. Click Send Configuration (see “Sending the Configuration to a Device” on page 4–4).
