PDM module issues
11.8.8 CARESCAPE Network communication issues
Traffic types
Two main types of communication occurs in the CARESCAPE Network: Broadcast and Unicast.
•
Broadcast traffic is sent from one device to all devices on the network. Examples of
CARESCAPE broadcast traffic are device discovery, alarms, and time synchronization.
•
Unicast traffic is sent from one device to another specific device on the network. An
example of CARESCAPE unicast traffic is patient waveforms.
Flow
•
Upstream broadcast: The patient monitor sends broadcasts to other network devices.
•
Downstream broadcast: The patient monitor receives broadcasts from other network
devices.
Possible cause
Recommended action
DC/DC board failure
The VSYS supply voltage for the PDM module is generated in the DC/DC
board. Check from the Webmin
Hardware Statistics
that the supply
voltages are within specification:
- VSYS voltage (mV)
- VSYS_EPORT(mV)
- VSYS_PDM (mV)
If PDM is connected to PDM dock, DC/DC board should identify PDM and
enable the VSYS_PDM circuit breaker on CPU carrier board to connect
VSYS voltage to VSYS_PDM.
If PDM is connected to ePORT, DC/DC board should identify PDM and
enable the VSYS_EPORT circuit breaker on CPU carrier board to connect
VSYS voltage to VSYS_EPORT.
If VSYS voltage is out of spec, the problem is most likely in the DC/DC
board. Replace the DC/DC board.
CPU assembly failure
The Ethernet communication for the PDM module is managed by the CPU
carrier board.
Check PDM Log for possible PDM errors messages, see section
If the cause is none of the above, the problem is most likely in the CPU
carrier boar. Replace the CPU assembly.
