The Hessen protocol is not well defined; therefore while ML’s application is completely
compatible with the protocol itself, it may be different from implementations by other
companies.
The following subsections describe the basics for setting up your instrument to operate
over a Hessen Protocol network. For more detailed information as well as a list of host
computer commands and examples of command and response message syntax,
download the
Manual Addendum for Hessen Protocol from the Teledyne ML’s website:
http://www.teledyne-ml.com/manuals/index.asp .
5.3.4.2. HESSEN COMM PORT CONFIGURATION
Hessen protocol requires the communication parameters of the T100’s COMM ports to
be set differently than the standard configuration as shown in the table below.
Table 5-13: RS-232 Communication Parameters for Hessen Protocol
Parameter Standard Hessen
Data Bits 8 7
Stop Bits 1 2
Parity None Even
Duplex Full Half
To change the rest of the COMM port parameters and modes, refer to Section 5.1.4.
To change the baud rate of the T100’s COMM ports, refer to Section 5.1.5.
IMPORTANT
Ensure that the communication parameters of the host computer are also properly set.
NOTE
The instrument software has a 200 ms latency before it responds to commands issued by
the host computer. This latency should present no problems, but you should be aware of
it and not issue commands to the instrument too quickly.
