Checking Revision Information

There are various ways to check revision information:
• Most of the revision information can be checked from reading the contents of the trace header --
see "Trace Header".
• You can also identify the hardware revision via the
Check" on page 106.
• You can also identify the software revision via the
Check" on page 107.

Trace Header

The trace header printed when the recorder starts, contains useful information about the monitor and
its parameters.
• The first line contains:
– the patient's name and ID
– the date of birth of the patient and the gestational age of the pregnancy
– the time and date, the paper speed and the bed label
• The second line contains:
– result of the self-test.
– firmware revision of the FPGA micro controller, responsible for controlling the recorder, the
display and the ultrasound tone. This revision is always fixed with a particular software
revision.
– revision of the internal recorder communication protocol. This revision is always fixed with a
particular software revision.
– paper type (US or INT).
– information on whether the recording is a real-time trace (RT appears), or a stored data/trace
recovery printout (RT is not printed).
– information on the print-head intensity (I).
• The rest of the information contains:
– product number, serial number and software revision of the monitor.
– Bus Master firmware revision (OB).
– serial number and firmware revision of connected devices.
If a transducer is plugged into the monitor after the recorder started, the serial number, and revision
information is annotated along the bottom of the trace.
