binary data:
Same data as that recieved by CFURD
Remarks: Loads binary data into the cal factor table. This command will automatically
save the data to the sensor.
CFUPT Preset cal factor table SENSOR
Syntax: CFUPT <s>,<table number>
s: A or B
table
number: 1 to number of tables supported by the sensor type
Remarks: Presets the cal factor table to the factory settings. The preset table is auto-
matically saved to the sensor. For a universal sensor, separate cal factor
tables exist for option 1 (when fitted) and normal operation. This function
will preset the table relating to the currently selected mode.
CFURD Cal factor table binary read SENSOR
Syntax: CFURD <s>,<table number>
s: A or B
table
number: 1 to number of tables supported by the sensor type
F for the factory default table
Remarks: This command outputs the cal factor table in binary mode in the following
form:
CFURD<space><length of binary data>,<binary data>
<length of binary data>: Total length of the binary data message, in bytes,
after the comma.
<binary data>: Made up of :
a. 8 bytes; 7 for the identity, plus a NULL terminator
b. 2 bytes representing the number of table pair entries
c. The cal factor table data in binary form. The binary data is output in en-
tries which are frequency/factor pairs of six bytes. The frequency is held in
32768e-6LONG format and the cal factor in 1024INT format.
To convert these into real numbers the first four bytes of an entry are read
into a LONG variable, cast to a float and then divided by 32768e-6 to give
a frequency. The last two bytes are then read into the low bytes of a
LONG then cast to a float and divided by 1024. The C programming ex-
ample 'Binary output decoding' on page 6-133 shows how to extract the
binary data.
