The Q- and T-SMINT I have been designed to be as compatible as possible. However,
some differences between them are unavoidable due to the different line codes 2B1Q
and 4B3T used for data transmission on the U
Especially the pin compatibility between Q- and T-SMINT I allows for one single PCB
design for both series with only some mounting differences. The
distinguish between the Q- and T-series by reading the identification register via the
IOM -2 (MONITOR channel identification command) or the
ID.DESIGN), respectively.
The following chapter summarizes the main differences between the Q- and T-SMINT I.
