118
Possible Cause
The Offset needs adjusting.
The wrong paper scale is being used.
Cause of Failure
The LAN/RS232 port is not configured for
data export.
The cable between the external device and
the monitor is not connected correctly or
defective.
The external device does not support the
version of the data export protocol used in
the monitor.
A terminal concentrator is used in between
the device and the monitor, and a protocol
with dynamic speed negotiation is used.
The LAN/RS232 board is in a wrong slot
(slot has been changed after software
configuration or an additional board has
been plugged in).
The LAN/RS232 board is defective.
Corrective Action
Calibrate the recorder and change the offset
-- see "Setting the Fetal Recorder Offset"
on page 97.
Ensure the paper you are using matches the
paper scale setting.
Failure Isolation and Remedy
Check the configuration of the LAN/RS232
ports in Configuration Mode.
Check the cable and replace it if necessary.
Check if the device supports the version of
the data export protocol. Upgrade the
device or the monitor if necessary (if
matching versions exist).
Some terminal concentrators do not
support changing the transmission speed
(baud rate) dynamically. Check if the
connection works without the concentrator.
Verify correct the placement of the I/O
boards.
Check the board and replace it if necessary.
