10 FAQ – Frequently asked questions
2013-10 W-DMX G4(S) User Manual, edition 2 51
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.
