Mounting

The WD PRO Receiver can access both power and data through a single Ethernet cable so that wiring space and costs can be minimized.

Wireless Quality Diagnostics

Displays the quality of wireless connection between the receiver and transmitter(s) using a 5-level evaluation system. Up to 72 hours of diagnosis data can be recorded so users can determine when and where the installation environment needs to be modified.

・Changes to the installation environment are recommended for diagnosis results of rank D or E. Communication quality is greatly affected by conditions in the installation environment, try the following.

No. Method Effect
1 Adjust the position, height, and orientation of WDR and WDT. Nearby objects interfere with and reflect radio waves from wireless communication. Communication may improve by moving, even as little as 1 m, the position or height of WDR and WDT.
2 To reduce their impact on wireless communication, move metal objects out of the way. If there is a large metal object in the installation environment, there may be spots where radio waves cannot reach. Communication may improve by moving metal objects out of the way.
3 Add an extra transmitter to the WD wireless network to act as a repeater and enable communication hopping. Adding a WDT to the WD wireless network increases the choice of communication paths. Even adding a WDT near the WDR could improve communication quality of the entire WD wireless network.
Run Multiple Applications Simultaneously

The WD PRO Receiver has multi-session capabilities meaning users can connect to multiple applications and software simultaneously.
