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
i Series 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 49 i Geysitech Protocol specification, see the
following topics:
