Setting the Retry Time for a Switch Failure
When you make a switch, a switch request is sent from the RCP-QE to the NK-NET (or NK-IPS) and forwarded to
the NK routing switcher. If the RCP-QE does not receive a response from the routing switcher, the RCP-QE retries
the request after the time specified in the
Comms Retry Delay Factor field.
Systems require different retry times depending on the transfer of requests and responses between modules.

If switch performance appears slow and the log shows multiple retry and timeout events, you should increase the
retry time.
To set the retry time:
1. Open the RCP-QE Panel Configuration editor (see “ Opening the RCP-QE Panel Configuration Editor ” on
page 4–4).
2. Select the Configuration tab.
3. In the Configuration section, use the Comms Retry Delay Factor box to adjust the retry time (in
milliseconds) according to the requirements of your routing switcher system (see Table 4.6 ).
4. Send the current configuration file to the device (see “ Sending a Configuration File to a Device ” on
page 4–33).
Returning to the Home Menu
You can use DashBoard to return to the Home menu if the RCP-QE is not responding to button presses.
To return to the home menu:
1. Open the RCP-QE Panel Configuration editor for the RCP-QE that is not responding (see “ Opening the
RCP-QE Panel Configuration Editor ” on page 4–4).
2. Select the Configuration tab.
3. In the Configuration section, select the Return to Home Menu check box.
4. Send the current configuration file to the device (see “ Sending a Configuration File to a Device ” on
page 4–33).
The RCP-QE returns to the Home menu.
