Does Not Connect to the Spectrometer

© 2007 ASD Inc.
To fix many communication errors (particularly if the instrument has been
functioning at some point), power cycle the instrument and/or the instrument
controller.
The sequence to use will vary depending on the computer manufacturer.
Either:
• Leave the computer on. Turn off the instrument. Wait for 10 seconds.
Turn the instrument back on.
• Or, turn off the computer and the instrument. Turn on the instrument.
Then turn on the instrument controller.
For the best performance, you should assure a clear line-of-sight between the
spectrometer and instrument controller. Obstructions or radio frequency
interference in close proximity can cause loss of communication or
significantly shorten the communication range.
The TerraSpec spectrometer uses industry standard components. You should
see the same general connection speed and distance capabilities as other
wireless devices.
• Refer to section A.1,
• Check that the Ethernet cable is securely inserted into the spectrometer
and host computer. Check that the Ethernet LED is on.
• For an isolated network, check that the Ethernet cable is a cross-over
Ethernet cable.
• For an established network, check that the Ethernet cable is a standard
Ethernet cable.
• Check that the IP Address is in the same range or subnet as the ASD
spectrometer. The same subnet means that the first three octets of the IP
address (xxx.xxx.xxx.___) match the spectrometer and the computer.
