Note:
1. Flashing: > 20ms ON + <180ms OFF (Depending on the refresh rate of
the DMX signal)
2. Fast-Flash: 100ms ON + 100ms OFF
3. Slow-Flash: 900ms ON + 100ms OFF
2.3 Select Wireless Group
Each time you press the button, the status indicator will change different
colors. In this case different colors mean different groups. Only when the
indicators of the transmitter and receiver show the same color they can
communicate with each other.
When the transmitter connects to the controller, the status indicator of the
transmitter would flash red. If the receiver gets the DMX signal, the
indicator would flash green.
NOTE: The first time when you press the button, it will not change the
color but show you the group that you are in. If you press it again it will
switch to other group.
W-DMX mode supports 6 groups
(FHSS, 1100 hops / sec)
1: RED ---------------------------- Red
2: GREEN ------------------------ Green
3: BLUE --------------------------- Blue
4: RED + GREED --------------- Yellow
5: GREEN + BLUE -------------- Cyan
6: RED + BLUE ------------------ Purple
GZ protocol supports 7 groups
(Frequency Agile)
1: RED ----------------------------- Red
2: GREEN ------------------------- Green
3: RED + GREED --------------- Yellow
4: BLUE ---------------------------- Blue
5: RED + BLUE ------------------ Purple

2.4 Restore factory settings
By pressing and holding the button (> 1S), When see the BLUE flashing,
Then release the button, the devices would flash "RED-GREEN-BLUE"
quickly, and then turns red. It indicates that the device has restored to
factory settings successfully. The default group is red.
2.5 Connection and Delete
Connection
In the W-DMX G3 or G4 Transmit Mode, by pressing the button, the
transmitter can be connected to all powered but not connected receivers
within the coverage area; Press and hold (> 3S) the transmitter’s button
until the indicator turns red. The device will disconnect with all receivers
within the coverage range.
In the W-DMX Receive Mode, Press and hold (> 3S) the receiver’s button
until the indicator turns white. The device would disconnect with the
transmitter.
Note: Receiver could only be connected to the new transmitter after the
old connection is deleted.
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.
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.
