Abstract:
1. A system for centrally setting a data rate in a data transmission facility, comprising: a) a central station; and b) subscribers; wherein said central station is disposed in series with said subscribers by a bus circuit; wherein said subscribers are disposed in series with each other by bus circuits; wherein each subscriber has a protocol core; wherein each subscriber has data rate detectors; wherein each subscriber has a data rate controller; wherein said central station outputs data rate setting telegrams of a data rate to be set in said subscribers; wherein a first subscriber inputs said data rate of said data rate setting telegrams outputted from said central station; wherein each data rate detector of a respective subscriber detects a data rate different than that of the other data rate detectors thereof to allow only one data rate detector to detect only one valid data rate and in response thereto generate only one data rate validity signal; and wherein said data rate detectors of said respective subscriber simultaneously receive and evaluate said data rate inputted until such time as said one valid data rate has been detected by said one data rate detector thereof forming a detected data rate and in response thereto said one data rate detector thereof sends said one data rate validating signal thereof to said data rate controller thereof and in response thereto said data rate controller thereof selects said one data rate detector thereof having said detected data rate to form a bypass-type connection through said respective subscriber to output said detected data rate from said respective subscriber to be inputted by a next subscriber in series therewith to be used thereby to start data rate setting therein and so on until all of said subscribers in series with each other have data rates set therein.
