audiences to ensure reliable operation. Care need to be taken to ensure
proper functionality.
Will other electronics and other W-LAN users interfere with it?
No, it is not affected by cell phones. Heavily loaded W-LAN can be a problem,
care need to be taken when you can expect a high use of several W-
LAN’s.
How many channels of DMX does it control?
Each transmitter can control 512 channels (1 universe) of DMX, unlike some
wireless systems which only have “half universe” or 256 channels. The F
-2
and the ProBox can additionally control a second DMX universe.
What antenna should I use?
For most indoor applications the 2 dBi antennas work fine. Longer distances,
outdoors or unique applications most likely will require different antennas.
Please contact us with your intended application questions. Warranty is voided
if using other antennas than W-DMX branded.
What is the transmission range?
With standard antennas the, maximum distance is 700 m/2300 feet (FCC
version). As an option it’s possible to connect other antenna models to achieve
longer distances or where there is a specific need for higher gain. (Distances
valid at 300 mW FCC)

How many receivers can be assigned per universe to the W-DMX in a
DMX512, DMX512A, or RDM installation?
DMX Receivers is only limited to the 512 channels per universe.
If RDM is activated, you are limited to 34 RDM devices, where each W-DMX
device is counted as one RDM device.
Can multiple transmitters run side by side (to support more than one
universe)?
Yes, up to 8.192 receivers can be controlled from one system, and the
standard configuration is with 512 DMX Channels and can easily be updated
with 8.192 DMX channels (16 DMX-512 Universes).
Is it FCC approved?
Yes. Please see chapter "Technical data", page 43, 45 and 47.

Are these products UL listed?
UL pending.
What is the typical power consumption?
450 mA average, 700 mA maximum.
Please see chapter "Technical data", page 43, 45 and 47.
Is there a warranty?
All BlackBox products are covered by a standard 12 month full warranty.
Can the antenna be mounted away from the transmitter or receiver?
Yes, there are indoor and outdoor cables available in lengths from 0,5 m to
30 m (1.6 to 98 feet).
Will the receivers stay logged on to the transmitter if the DMX signal is
lost?
Yes, even if the DMX signal is interrupted the receiver(s) will remain logged in.
Will the units stay logged in to each other if power is cut?
The log-in information is stored in an EEPROM and will not be erased. No
battery backup is needed. In theory, the units stay logged in forever.
In an operational system, can I log on an additional receiver without
disrupting DMX transmission to other receivers?
This is not possible with the BlackBox unit. Logging on an additional receiver
will make the logged-in units revert to idle mode for 10 seconds; once the new
units are logged-in they will all start again together with the new unit.
What is the difference between Multicast and Point to Point?
Multi-cast: transmitting to multiple receivers simultaneously.
Point to Point: data is a single path of data transmission.
What is FHSS?
Short for Frequency Hopping Spread Spectrum
–
Frequency hopping
techniques, in which the transmitter jumps from sub-channel to sub-channel at
rapid pace, were first used by the U.S. Military. Such techniques were
developed precisely because they are difficult to disrupt and, unless you know
the frequency hopping sequence, practically impossible to intercept. Spread
spectrum techniques have two main advantages: Firstly, they are more
resistant to interference than conventional systems. Secondly, they can be
used to provide multiple access functionality.
Does W-DMX support on-site service with technical documentation after
visit?
Wireless Solution and/or its distributors offer Cell Planning Service for larger
projects. Please contact your local distributor for a quote. This is highly
recommended for all larger projects to save time and money.
