Configuring NK Series Routers and Panels
Sending crosspoint commands via the NK-Hub adds delays to the switch messages. Control panels, in particular,
must be configured to minimize unnecessary retries and tolerate longer delays in receiving responses.
Configuring Retry Delay
The retry delay sets the maximum time a panel will wait for a response before retransmitting switch requests. If this
delay is shorter than the round trip through the NK-Hub and the receiving NK-IPS, then retrying will worsen the
situation by adding more switch requests to handle.
To set the retry delay:
1. In DashBoard, double-click the control panel in the Basic Tree View.
A tab for the control panel opens in the main window.
2. In the Configuration section, set the Comms Retry Delay Factor to 250ms.
