10. Troubleshooting
This section covers some common problems that might be encountered when
using the NL241. 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 NL241, do the following:
1. Check all your power connections.
•
Your NL241 and any wireless access point (WAP) and/or wireless
router being used must be connected to power. Check power indicator
lights to make sure your devices are powered.
2. Check all your cables and antenna.
•
Verify that your antenna is securely attached to the NL241 and
oriented in the same direction as the antenna of your WAP. The
Link/Act light on the NL241 should start blinking when it is
connected to a network. Also, the WLAN activity light on your WAP
(if it has one) should be blinking with activity as well.
