CARESCAPE Monitor B650
Possible cause
CPU board failure
PDM module issues
Possible cause
The external ePort cable is loose
or defectice.
(PDM is connected to the ePort
connector in advanced interface
board)
DC/DC board failure
Advanced interface board failure.
(PDM is connected to the ePort
connector in advanced interface
board)

Recommended action
The RS-485 communication for the E-modules is managed by the EMBC
section of the CPU board.
- Check EMBC Frame logs for possible EMBC failures, see section "11.3.4".
If the cause is none of the above, the problem is most likely in the CPU
board. Replace the CPU board.
Recommended action
Check that the external ePort cable is intact and properly connected to the
PDM module and to the ePort connector in the advanced interface board.
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.
Check the status of the VSYS OPTION voltage measured from the
advanced interface board (see section
If the VSYS OPTION voltage is out of spec, but the VSYS voltage exists in the
DC/DC board, the problem is most likely in the advanced interface board.
Replace the advanced interface board.
