Reception Level Monitor - Omron V780-Series User Manual

6 Functions
Precautions for Correct Use
• The RUN indicator will light cyan during the scan.
• During a scan, the NORM/ERR indicators will flash once in red or green according to the
results of multiaccess communications.
• During the scan, the Reader/Writer will repeatedly communicate with the RF Tags to read the
IDs with multiaccess communications.
• The scan list is updated approx. every 1.5 s.
• If you close the Web browser interface or disconnect the communications cable during scan-
ning, the test operation status (i.e., the RUN indicator lit in cyan) may continue. If that occurs,
cycle the power supply to the Reader/Writer to reset it.

Reception Level Monitor

Outline
You can check the reception level from RF Tags over time on a graph.
You can use this to adjust the installation locations of Reader/Writers and RF Tags and measure the
communications ranges to achieve more stable RFID system operation.
Broadly speaking, you can use the Reception Level Monitor View to analyze two communications
methods: single-access communications and multiaccess communications. You can also save the
reception level information measured by the reception level monitor in a file.
Measurement Method for Single-access Communications
To analyze communications with individual RF Tags with the reception level monitor, select the Sin-
gle Option and then click the Start Button. When analysis begins, the Reader/Writer will start taking
measurements and the reception level display for the RF Tag will be updated in realtime. To stop
taking measurements, click the Stop Button.
