Reading Device Information
You can read the device information given in the following table from the Reader/Writer.
You can send a command from the host device or access the information from a Web browser to read
the device information.
Noise Measurement
Communication performance will be reduced when the RF tag or the Reader/Writer are influenced by
ambient noise. The Reader/Writer responds the ambient noise level by using noise monitor function.
The response data includes the following parameters. By checking the noise level, you can check the
influence on the performance of communication with the RF tag in advance. You can also check the
noise level when the trouble occurs.
The noise monitor can be performed by means of the following two.
Measuring Noise with a Command from the Host Device
You can send the MEASURE NOISE command to the Reader/Writer to obtain the numerical ambient
noise level around the Reader/Writer.
Refer to MEASURE NOISE in V680S Commands in Section 5 Host Communications Specifications for details on the MEASURE
NOISE command.
p.134
Noise measurement using Web browser.
You can check the transition graph of the noise level using WEB browser.
By selecting the type of the RF tag, you are also able to visually confirm the stability of communication.
Refer to Noise Monitor View in Section 6 Browser Interface for more information.
p.154
If the noise level that was confirmed by WEB browser screen may affect the performance of
communication, do the following actions.
If the other Reader/Writers are operating close to the Reader/Writer, ensure the distance between
the Reader/Writers.
p.232, p.233, p.235
If the equipment close to the Reader/Writer, become a source of noise transceivers, motors,
inverters, and switching power supply is running, ensure the distance until the amount of noise is
sufficiently reduced. Take action, such as enclosing the noise source by metal object.
