communication errors when connecting a PCD/PCS in "Secure S-Bus Data Mode"? (FAQ #101180) In case a "non Saia PCD® COSinus" PCD or PCS1 system is connected with "Secure S-Bus Data mode" (e.g. over a serial cable or over modem) from time to time a telegram is not answered correctly. Symptom A PCD or a PCS connected with another system (e.g. PC or another PCD system) using the "Secure S-Bus Data mode" does not answer a telegram from time to time. This can e.g. be seen by a red LED on transmit or receive FBoxes

(FAQ #101775) The RS-232 S-Bus [...] V020) it may be, that the S-Bus communication over converters (like modem or optical converters) to other devices does not work. The S-Bus communication works fine, if no converters are used in between. Also other communications protocols then S-Bus like "Mode C, Modbus" works fine on the PCD2.F2xx0 and PCD3.F2xx module (with and without converters in between). On the print screen below

Why it’s not possible to make the binding with the LonMaker to a PCS1? (FAQ #101132) If a PCS1 does use at the same time a serial communication with > 9’600 baud and the user wants to make a binding with the LonMaker then it’s possible that the binding will not succeed and on the LonMaker there is an error message
