On an SD network, there has been reported that collections from PN are interrupting and sometimes stopping normal data flow. Per the GE PAG lab, the SD radio cannot handle being queried every few seconds. A workaround is to slow down the PulseNET Dlink polling with the following changes.
The parameter is for Passive Collections and is found under Configure Collection for every DLINK Master device. Drill into the Device Detail display on the master, go to the gear icon and select Configure Collections. Change the Repeat Interval to at least 60,000 ms for SD devices.
