Symptom Possible Cause Corrective Action
Symptoms Cause of Failure Failure Isolation and Remedy
External device (such as a
surveillance system like
OB TraceVue/
IntelliSpace Perinatal) not
receiving data.
The LAN/RS232 port is not configured for
data export.
Check the configuration of the LAN/RS232
ports in Configuration Mode.
The cable between the external device and
the monitor is not connected correctly or
defective.
Check the cable and replace it if necessary.
The external device does not support the
version of the data export protocol used in
the monitor.
Check if the device supports the version of
the data export protocol. Upgrade the
device or the monitor if necessary (if
matching versions exist).
A terminal concentrator is used in between
the device and the monitor, and a protocol
with dynamic speed negotiation is used.
Some terminal concentrators do not
support changing the transmission speed
(baud rate) dynamically. Check if the
connection works without the concentrator.
The LAN/RS232 board is in a wrong slot
(slot has been changed after software
configuration or an additional board has
been plugged in).
Verify correct the placement of the I/O
boards.
The LAN/RS232 board is defective.
Check the board and replace it if necessary.
