Terumo CDI 550 Operator's Manual page 136

The first four parameters configure the RS-232 interface, while the last parameter
indicates the interval that data will be sent out through the serial port. Intervals are
measured in minutes, so an interval of 1.0 is once a minute, and an interval of 0.1 is
once each six seconds. If the output interval is set to 0.0 no data will be sent out the
port unless the user sends an output request packet, which is described later in this
appendix.
Data output events.
A header line will print out every 50 lines of data for viewing convenience. Data will
be sent out the serial port when any of the following events occur:
„ Specified output interval has been reached
User marks data by pressing the "mark" button during operation
„
User stores data by pressing the "store" button during operation
„
„ User returns from the "recalibration" screen
User sends a request via the serial port for a line of data
„
While in ASCII Output mode, a line indicating temperature display value will be output
initially and every time the user changes temperature modes. This line will either be
"@ Temp Data" or "37C Temp Data" depending on the condition of the monitor at the
time.
User request for data.
You can send a packet to request that a line of data be sent out the serial port. The
request packet is the following:
Upon receiving this packet, the CDI System 550 will get the latest parameter informa-
tion and send it out the serial port. The format will be identical to lines of data sent
out at timer intervals, marks and recalibrations.
ASCII Output Format.
Blood parameter values are sent out the serial port as configured when the system is
in "operate" mode. All values are delimited by tabs, and the packet is terminated by a
Carriage Return <CR>. Additionally, if a parameter is out of bounds (as configured in
the setup screen for each parameter), the numbers will be displayed as dashes, and
if a parameter is not available (based on the configuration of the monitor), the field will
be filled with blanks. If the format is smaller than the field size, it is prepended with
blanks. The format of the output is as follows:
