6.1.3 About the MAC Address

・Static address assigned to WDT-PRO for identification. This address is called a MAC address (IEEE address).
・The MAC address is printed on a nameplate on the back of the WDT-PRO.

6.1.4 How many WDT you can connect to WDR

The number of WDT units you can connect to a WDR is limited by the frequency of information sent to the WDR.
The total transmissions from all WDT connected to the WDR is limited to 120 or less per minute (transmission
interval of 0.5 seconds or longer). To satisfy this condition, use the following table as a guide and determine the
number of connected units.
WDT connection limit
30 unit
20 unit
10 unit
5 unit
1 unit

6.2 About the Installation Environment

6.2.1 Installation Environment Main Points

There are five essential points to consider at installation.
No.
There is no influence in radio waves at the installation site. Also,
1
the radio waves at the installation site do not change over time.
The distance between devices (WDR, WDT) does not exceed
2 recommendations. The recommended distance between all WDT
and WDR is within line of sight.
Each device (WDR and WDT) is in line of sight. To ensure good
3 line of sight, the location should not be cluttered and should be
free of any obstacles.
WDR placement is appropriate.
4
・Install in a location as high as possible.
・Install away from obstacles that could disrupt radio waves.
Each device is always powered, and the mesh network is always
available. If power is not available for one of the WDT, the
5
communication path could get interrupted and information may not
be transmitted.
