Vaisala CWL100 Quick Manual page 8

Range of the wireless connection
Range of the wireless connection between a CA10 access point and CWL100 data logger is 100
meters (328 ft) in a typical indoor space. In an open space with line-of-sight and no interfering
structures, the range can be over 500 m (1640 ft).
To extend the signal coverage, use multiple access points. This will also allow data
loggers to automatically switch to an access point with a stronger signal if the
connection is unstable. You can have up to 8 access points in the same area (in
range of each other) but you must set each of them to their own radio channel.
You can change the channel using the Jade service after you have connected the
CA10 to the Internet.
CWL100 info mode
CWL100 data logger has a small button next to the service port. Pressing this button enables
Info mode for 1 hour, after which the mode is automatically disabled. Pressing the button again
disables the mode immediately.
In the Info mode:
• Data logger starts radio scanning immediately if it has shut down to save power.
• After showing the current measurement results and possible error codes, the data logger
shows the text INFO ON and the following additional information:
• If the data logger is connected to an access point:
• Signal strength indicator
• The currently connected access point channel is shown, alternating with
measurement results and firmware version.
• Firmware version of the data logger.
• Serial number of probe detected at startup, shown in 3 separate segments. Letters SN
are shown before the number.
After all information has been shown, the same sequence is repeated until Info mode is
disabled or 1 hour has passed.
