7.1 INFO PIN
An optical data interface on the front is available for the end user. Its constant data rate is 9600 baud and the character
encoding is 8-N-1. The transmission protocol is according to SML specification version 1.04. The interfaces work in
"PUSH" mode and send out one data record every second. The data has 3 variants. If you do not enter a PIN for the
"INFO OFF" setting, it is the "Reduced data record", otherwise it is the "Complete data record". The “manufacturer-
specific data record” can also be activated or deactivated via the rear interface.
