Setting the Retry Time for a Switch Failure
When using an NK series router with an RCP-ME and you make a switch, a switch request is sent from the
RCP-ME to the NK-NET (or NK-IPS) and forwarded to the NK routing switcher. If the RCP-ME does not receive a
response from the routing switcher, the RCP-ME 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-ME Panel Config interface (see “To open the RCP-ME Panel Config interface” on page 22).
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 3.1).
4. Send the current configuration file to the device (see “To send the current configuration to a panel” on
page 74).
Making a Switch
A switch can be made with or without a TAKE button assigned to the menu. If there is no TAKE button assigned, a
switch is made when the source/crosspoint/macro button is pressed. If a
TAKE button is assigned to the menu, the
switch is made when the
TAKE button is pressed.
Switching with a Breakaway, Destination, and Source
If you are in Cutbus mode, you cannot select a destination button.
To make a switch
1. Press the button(s) for the level(s) or breakaway that you want to use.
If you do not select a custom breakaway or level button, the default breakaway is used.
To de-select a level, press the button again.
You may need to use a DST SH1 or DST SH2 button before the destination button.
2. Press the destination button that you want to use.
In the example below,
EDIT 3 is the selected destination.
You may need to use a SRC SH1 or SRC SH2 button before the source button.
