Keep both the DTR and your computer powered while you check the diagnostic LEDs.
If both LED lights are turned o, check the f
ollowing:
• Both the DTR and the device in the other end of the cable are powered on
• The Ethernet cable is properly inserted in both ends
• The Ethernet cable is of the correct type (cross-over cable for direct DTR-to-computer
connection)
If the green LED is lit, your Ethernet connection is made correctly with the right type of
cable. In this case, try pinging the DTR and check if the orange LED flashes during ping.
If the orange LED does not flash, check that the IP address matches the IP address of the
DTR. In case the DTR is not connected directly to the computer, there may be a routing
problem. Please consult your network administrator to solve the problem.
A
firewall software with tight settings may stop you from connecting to a DTR. If you are
connecting directly to the DTR and you are not in a network, turn o the firewall
temporarily while working with the DTR. Remember to turn on the firewall before
connecting to a network again.
15.4 Instrument homepage
From DTR program version 2.0 onwards every DTR has its own built-in instrument
homepage that contains information about the instrument and a remote panel with full
functionality. The instrument works like a web server, so you only need a working Ethernet
connection to the DTR and any web browser to access the instrument homepage.
