Data input via RMGBus

The data of a gas chromatograph (eg. RMG GC9000 or GC9300) can be delivered
as RMGBus telegram via the RMGBus protocol. Therefore, the coordinate AX-01
"SoS AGA-10 source data" is set to "Serial port 2" and the serial interface in the
mode "RMG- Bus". Additionally the parameters of the interfaces USM-GT-400 and
the RMGBus master device have to be aligned to each other.
Because the content of the telegram may have data from different streams, the
„right" stream has to be set with the parameter AX-09 "Stream selection". Parame-
ter AX-08 "RMGBus mode" fixes how many components are part of the telegram.
When using a GC9000 this parameter has to be set to "RMGBus" to offer a correct
evaluation for older versions of the software GC9000.
