Appendix D
Geysitech (Bayern-Hessen) Protocol
This appendix provides a description of the Geysitech (Bayern-Hessen or
BH) Protocol Interface and is supported both over RS-232/485 as well as
TCP/IP over Ethernet.
The Geysitech Commands that are implemented are explained in detail in
this document. The Geysitech 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 Geysitech commands
listed below.
For details of the Model 42i Geysitech Protocol specification, see the
following topics:
