Appendix D
Gesytec (Bayern-Hessen) Protocol
This appendix provides a description of the Gesytec (Bayern-Hessen or
BH) Protocol Interface and is supported both over RS-232/485 as well as
TCP/IP over Ethernet.
The Gesytec commands that are implemented are explained in detail in this
document. The Gesytec protocol support for the iSeries enables the user to
perform the functions of reading the various concentrations and to trigger
the instrument to be in sample/zero/span mode if valid for that instrument.
This is achieved by using the supported Gesytec commands listed below.
For details of the Model 48i Gesytec Protocol specification, see the
following topics:
