3 Applications

3.1 One transmitter to one
receiver

Controller inputs DMX signal onto a wireless transmitter, and
the latter would send DMX signal via Radio to the receiver
with the same group or to the receiver connected.

www.widmx.com LC-512 Series User Manual

16

3.2 One transmitter to many
receivers

Controller inputs DMX signal onto a wireless transmitter, and
the latter would send DMX signal via Radio to the receivers
with the same group or the other receiver connected.

3.3 Parallel Transmission

Many sets of radio transmitters can be operated
simultaneously, without mutual interference.

3.4 Repeater or Amplifier

If directly connect a receiver to a transmitter (both the
receiver and transmitter work in different groups or in
different sets), it would become a repeater or amplifier. In
this way, the working distance increases.
