Losing depth on TZTBBX

While underway today in a shallow area with a silty bottom I lost my depth reading from the Airmar DST200 n2k sensor. Nothing unusual here given the silty bottom the sensor wasn’t getting a signal bounced back. After a short while the DST200 started reporting the depth again which I could see on my RD33 screen, however my TZTBBX and TZT2BB both continued to show no depth reading (“- -“). I went into the settings screen on both the TZTBBX and TZT2BB data sources and the DST200 wasn’t showing as being available. I know the DST200 was putting data on the n2k network as it was showing a proper depth on the RD33 screen. I tried rebooting both TZTBBX/TZT2BB and the depth still didn’t show up. Only after I rebooted the entire n2k network did the DST200 show up again on TZTBBX/TZT2BB.

Is this normal behavior for both of these devices to not recognize n2k sensors that reappear on the network?
