Testing Ethernet Connection - Vaisala PR-23 Series User Manual

PR-23 Series User Guide
You may have to connect the cross-over cable and power on the DTR before your
computer generates an IP address for the Ethernet connection (computer reboot may also
be required). The connection does not work if the computer and the DTR have exactly the
same IP address.
Please make sure that your WLAN (Wireless network connection) is not active when you
connect to the DTR. If the WLAN is active, the computer's Ethernet connection may not
function as expected.
When you have set the DTR (and/or the computer), you can proceed to testing the
connection, see Testing Ethernet connection (page
15.3 Testing Ethernet connection
On the Ethernet connector inside the DTR there are two diagnostic LEDs.
• The green LED indicates that the physical connection is working. Both ends of the
Ethernet cable are plugged in, the device in each end is powered and the cable is of
correct type.
• The orange LED indicates traffic in the cable, DTR receives data.
You can test the IP address with a ping command after you have set up the physical
Ethernet connection and the DTR is powered. To use ping:
1. Go to the command interface (for example, Command Prompt in Windows).
2. Type ping and the IP address you want to check.
3. Press ENTER.
If the Ethernet connection is good, the DTR is powered on, and the address is correct, the
DTR answers to ping and returns any data packets sent to it. If DTR returns and error
message, see Troubleshooting connection (page
