7.2.2

Protocol

All sensors of the DM series are using a binary protocol. Alternatively, they can be switched to an ASCII protocol (only LT versions). To get a fast
communication the protocol has no additional overhead with CR, LR or ACK bytes.
7.2.3

ASCII-Protocol

The models LT21, LT151, LT201, LT21H and LT101H can be switched to ASCII by changing the first figure of block 3 of the head calibration code.
This figure has to be changed from 0 to 4 (old sensing head) or 8 to C (new sensing head). [►4.3 Exchange of the Sensing Head]
Example (new Sensing head): Binary-Protocol:
