11.4.1 Remote panel
Figure 11.11 DTR remote panel
The instrument remote panel is a
fully functional virtual DTR where
keys on the keyboard are clicked
with a mouse.
The DTR doesn’t
make any difference between com-
mands coming from the actual key-
board and from a remote panel. All
commands are executed in the order
the DTR gets them, independent of
where they come from.
Note: The DTR display picture on
the remote panel sometimes has a
slight lag (of few seconds) before it
refreshes.
This depends on many
factors like the computer and net-
work used. If the DTR seems to ’skip’
displays, it may be that it is executing
mouse-click keyboard commands faster than your browser updates the picture.
11.4.2 Sensor verification certificate
A sensor verification certificate can be viewed and printed by following the Veri-
fication link on the link bar. For more information on instrument verification, see
Chapter 12.
11.5 Collecting data via Ethernet
The main purpose of the Ethernet connection is to collect measurement data
from the instrument. For this data acquisition, you’ll need to have suitable soft-
ware on your computer. One solution is to get the software package from K-
Patents. The package contains a ready-to-use data acquisition program for Win-
dows 2000/XP/Vista.
However, if you need a tailored system, you can also program a downloading facil-
ity yourself following the specifications below.
Note: K-Patents guarantees that the specifications are correct, but cannot as-
sume any responsibility or provide support for other software than the unmod-
ified K-Patents software.
11.5.1 Communication protocol
The communications protocol is based on UDP/IP to port 50023. It is a
client/server protocol, where the DTR is the server and thus only sends informa-
tion when the client (i.e. your computer) requests it. The server should answer to
all requests within five seconds (5000 ms) from the request, usually the response
time is below 100 ms.
