Data format
1 start bit, 7 data bits (ASCII), 1 parity bit (odd), 1 stop bit, 1200 baud, full duplex
Serial data has the format: start text character, “<stx>”; Care Plus header, “CP”;
software version; data string; checksum characters; carriage return, “<cr>”; line feed, “<lf>”;
end of text character, “<etx>”. Data elements are separated by spaces, “_”.
Each String contains 53 characters:
Sample data:
<stx>CP0300_36.52_34.20_P_34.80_36.50_00001000_E014_11<cr><lf><etx>
Data for discussion (use the following table):
<stx>CPxxxx_pt.pt_at.at_m_ac.ac_pc.pc_alrmleds_code_ck<cr><lf><etx>
<stx>
Start of text character (ASCII 2); indicates a string of data will follow.
CPxxxx
CP means the data is from the Care Plus; xxxx is the software version in the unit,
e.g. 0300 for version 3.00.
pt.pt
This is the patient temperature in degrees centigrade. The patient temperature will always be
sent even if it is outside the normal display range. Temperatures less than or equal to 1.00°C
indicate an open or a disconnected probe. Any temperature greater than or equal to 50°C is a
shorted probe.
at.at
This is the air temperature in degrees centigrade. The air temperature will always be sent
even if it is outside the normal display range. Temperatures less than or equal to 1.00°C
indicate an open or a disconnected probe. Any temperature greater than or equal to 50°C is a
shorted probe.
m
This is the mode of operation. P means patient control mode. A means air control mode.
Always check the mode of operation before evaluating the air and patient
control temperatures.
ac.ac
In the air control mode, this is the air control temperature set with the
M
and
?
switches. In the patient control mode this is the air temperature that will maintain the
patient control temperature (or DET). The DET is calculated by the software and changes
in response to infant condition, incubator heat loss, etc. Both readings are in degrees
centigrade.
pc.pc
In the patient control mode, this is the patient control temperature set with the
M
and
?
switches in degrees centigrade. It has no significance in the air control mode.
