Site Survey
The site survey test shows overview information for wireless networks in a local geography. Using this
test, users can scan for working access points, check their operating channels and see signal/noise
levels. To start the scan simply select the Site Survey menu.

Monitoring
The Monitoring function shows Received/Transmitted bytes statistics per device.
These statistics show a five-minute average traffic rate over the last 24 hours period. RX (blue)
indicates incoming (Received) traffic and TX (red) indicates outgoing (Transmitted) traffic.
TX/RX monitoring is restarted on every reboot of the device. The reason is that the device has no real
time clock, so the time used is relative to the restart time. The first statistics appear as two points, five
minutes after the device has been restarted. A normal view is acquired 10 minutes after the P-360
reboots. First click the Show button to view the initial TX/RX statistics in the browser window. Click
the Refresh button instead of the Show button to get updated TX/RX statistics.
You can also change the TX/RX graph time interval. There are two drop-down menus used for this
purpose:
• The first one is used to choose the start hour of the interval. It is possible to choose any hour from
the last 24 hours (0-24), but the choice may be limited depending on the devices reboot time.
• The second drop-down is used to choose the time scale. The possible choices are from 0 to a
maximum of 23 hours.
For example: select time interval from 21 interval of 3 (time scale). Such selection shows graphic
starting from 21 hour after the device is started and up to 3 next hours. Following the same logic:
Select from 0 interval of 24 – full TX/RX graphic is displayed.
Selecting from 24 interval of 1 – the last hour TX/RX graphic is displayed.
