12.3 ASCII Protocol
The models CT-SF02, CT-SF15, CT-SF22, CTH-SF02, CTH-SF10 can be switched to ASCII by changing the
first figure of block 3 of the sensor calibration code. This figure has to be changed from 0 to 4 (old sensor)
respectively 8 to C (new sensor) (always +4; that means on the CTex this figure has to be changed from 1 to
5), see 7.5.
Old sensor CTex (+1) ASCII (+4) CTex + ASCII (+5)
0 1 4 5
New sensor
8 9 C D

After you have modified the sensor calibration code a reset is necessary to activate the change, see 9.
To switch to the ASCII protocol you can also use the following command:
Decimal: 131
HEX: 0x83
Data, answer: byte 1
Result: 0 – Binary protocol
1 – ASCII protocol
