9. Troubleshooting
This section covers some common problems that might be encountered when
using the NL200/201. This is not comprehensive but should provide some
insight and ability to correct simple errors without a call to Campbell Scientific
technical support.
When your Campbell Scientific software cannot establish a link to a remote
datalogger that is connected to the NL200/201, do the following:
1. Check all your power connections.
x
Your NL200/201 and any hub and/or router being used must be
connected to power. Check power indicator lights to make sure your
devices are powered.
2. Check all your cables.
x
Verify that your Ethernet cable is securely plugged in between your
NL200/201 and your hub, router, or PC. The yellow Link/Act light
on the NL200/201 should start blinking when it is connected to the
Ethernet.
x
If an Ethernet cable is connected but the Link/Act light is not
blinking, try a new Ethernet cable. You can also try moving the
existing Ethernet cable to a functioning system to determine if the
cable is working.
3. Power cycle the NL200/201 and your hub/router/PC.
x
Turn off or unplug your hub/router/PC and NL200/201. Wait 10
seconds and then plug them back in or turn them on. A full restart
may take 30 to 60 seconds.
4. Check the settings of the NL200/201.
x
Make sure the assigned NL200/201 IP address (DHCP or static) and
the IP address of the PC you are trying to connect from are able to
communicate with each other. (Your network administrator can help
you with this.)
For example, the following addresses are able to communicate:
NL200/201: IP address: 192.168.0.2, Network Mask: 255.255.255.0
PC: IP address: 192.168.0.3, Network Mask: 255.255.255.0
x
If you are using DHCP to assign an IP address to the NL200/201, use
DevConfig
to read the IP address assigned to your NL200/201. This
is done through a USB connection to the NL200/201 while the
NL200/201 is connected to your network.
x
The IP address assigned to the NL200/201 must be unique on your
network.
