Step 3 Checking for 2.4 GHz Interference
Step 4 Checking the Monitor Function
Step 5 Checking the Control Function
Verify that there is no interference in the frequency bands used for Cross Remote.
Procedure
Power down all DWX equipment so that no RF signals in the 2.4 GHz band are emitted by the DWX
system.
Use a spectrum analyzer or WiFi spectrum analysis application for PC, smart phone, or tablet PC to verify
that there is no interference in the 802.11.4 band on channel 14 (2.420 GHz), channel 19 (2.445 GHz),
and channel 24 (2.470 GHz).
If there is interference, increase the distance between the system and interference sources, stop
operation of the interference sources or move these to another frequency, to eliminate the interference.
Caution
The W-DMX wireless remote control system for lighting equipment and similar systems also may use the
2.4 GHz band. Pay special attention to such devices.
Note
If radio interference between wireless LAN or other systems cannot be avoided otherwise, you may be
able to avoid interference by selecting the remote control channel with [Custom] enabled in [Setting] of
the RMU-01 setup tool. When [Custom] is selected, the automatic selection of the optimal remote control
channel for the transmitter will be ignored. In such cases, signals from the transmitter may affect remote
control. Be sure to verify operation before beginning actual use.
In a Cross Remote configuration, UHF reception forms parts of the network system. Use Wireless Studio to check
transmitter information received via WiDIF-HP and passed onto the network.
Procedure
Make suitable settings for frequency, security mode etc. so that the transmitter WiDIF-HP information can
be received by the receiver.
Check the status of received transmitters using the display on the receiver.
Check the status of received transmitters using the Wireless Studio screen.
If the transmitter status cannot be checked even if reception has been set up properly, there may be a
problem with the UHF service area.
Return to the channel plan selection and RF level setting stage, and establish other suitable settings.
While checking whether the obtained service area fulfills the requirements, determine the installation location
and number of RMU-01 units.
Procedure
Perform transmitter and receiver pairing and set the control function to ON.
Have a person wear the transmitter as for actual operation and move throughout the service area, to
check conditions at various locations.
Points to check
“Cross Remote” control condition is not interrupted
Control function is operative
If the obtained service area does not fulfill the requirements, change the installation location and
number of RMU-01 units to increase the RF reception level, and check the service area again.
Increasing the RF reception level
Change the antenna installation position, aiming for
close proximity to service area
line of sight to transmitters
position overlooking service area
Increasing RMU-01 unit count: Up to 9 units are supported
