The format of the information transmitted from the 120 Series Monitor to the
external computer is shown in
NOTE: This applies to both 115 Update mode and 115 Transmit/Receive mode.
The definitions of the bytes are as follows:
This field contains a 1-byte ASCII value indicating the type of monitor sending the
information. The 120 Series Monitor is set to a fixed value of 9 (39H).
This 1-byte value indicates the type of information being sent from the 120 Series
Monitor as shown in
This 1-byte ASCII value indicates the ID number of the monitor information. The
120 Series Monitor sets this byte to a fixed value of 0 (30H).
This field of n-bytes contains the actual data sent from the monitor to the external
computer. The contents of this field for each response is given below:

Event Mark

This data field is empty whenever the monitor's

Heart Rate

This data field contains two or three ASCII characters representing the value of the

This data field contains two ASCII characters indicating the mode. The first
character is the combined mode of both heart rates according to
second character is the mode for uterine activity as listed in
transmitted at startup, with each mode change, with each request, and once every
minute.
