CBMF 1: Timed out waiting for samples #45
Description
EM712 went from collecting data swimmingly to a depth read out of -0.3m or -0.2m during turn. Unable to collected data after.
Troubleshooting: Power cycle of computer and PU did not remedy the problem. Powered cycle the PU twice.. once for 5 minutes and once for 3 hours. This is the error print out on telnet session:
CBMF 1 : Timed out waiting for samples OBJ_TIMEOUT 4004 remaining: : 4004 was expected
In July 2023, we had a different issue with the CBMF that was resolved by editing the Spanning Tree in the switch.; this issue was related to network connections on system. Note - this problem occurred on both our EMs onboard (EM304 and EM712) and was not unqiue to one system.
Simultaneously, we've been experiencing a bug (Togrims words from KM Support) where on initialization of sonar, the K-Controller will automatically terminate SIS and sent the system into an automatic start-up sequence. The only way out of this loop and to collect data is to restart the HWS and turn off system PU for at least ten minutes.
I am emailing KM support with this issue, but wanted to report on this wiki in case anyone has experienced anything similar. Screen shot with telnet attached.

UPDATE 2 SEPT 2023
The error --> "CBMF 1 : Timed out waiting for samples OBJ_TIMEOUT 4004 remaining: : 4004 was expected" corresponds to losing connection with the RX Unit. We confirmed we lost connection by checking the link lights in the ethernet connection on the physical unit in our Sonar Room (see attached picture). Further testing showed that we have 230V going into the power supply but nothing coming out of the power supply - the board is dead! We are working with Kongsberg to getting a spare delivered (luckily one was already purchased as part of a recent spare order).
Note, this error is not linked to the separate CBMF issues as noted above.
