Description of Status Indicator

1)In the Set-up mode, different colors mean different communication protocols:

1. Red ----------------- WIDMX Protocol
2. Green -------------- W-DMX Receive Protocol
3. Blue ---------------- W-DMX G3 Transmit Protocol
4. Yellow ------------- Guangzhou(GZ) Protocol

2)In the Use mode, Description of Status Indicator:

Protocol Action Status Description
WIDMX or GZ Protocol Red, Green, Blue,Yellow, Cyan, Purple (, White) 6 / 7 Different Wireless Groups
Flashing Red Transmitting DMX Signal
Flashing Green Receiving DMX Signal
W-DMX Receive Protocol White Connection is not Established
Red Deleting Connection
Red(Fast-Flash) Connection is Lost
Green(Fast-Flash) Connecting to Transmitter
Green(Slow-Flash) Connected, Without DMX Signal
Green Connected, Receiving DMX Signal
W-DMX Transmit Protocol Red Deleting all Receivers’ Connection
Blue(Fast-Flash) Connecting with the Receiver(s)
Blue(Slow-Flash) No DMX Signal Input
Blue Transmitting DMX

Operation Guide

1.Set-up mode:

Press and hold the button before you power up. When you see status indicator turns into the white light, release the button to enter the Set-up mode. In this mode you can select different transmission protocols. Each time you press the button, you would see the status indicator changes in following order: red, green, blue and yellow. Choose one of the protocols,then press and hold the button (> 1S), when you see the white light, release it to enter the use mode.

2.Use mode:

1) Powered up and enter the Use mode;
2) If it is in Set-up mode, press and hold the button (> 1S) until you see the white light, then release it to enter the Use mode.

2.1.In WIDMX protocol or GZ protocol, you could select different DMX Group:

1) The first time when you press the button, it will not change the color but show you the group that you are in.
2) If you press it again it will switch to other group.

2.2.In W-DMX Transmit protocol:

1) By pressing the button, the transmitter can be connected to all powered but not connected receivers within the coverage area;
2) Press and hold (> 3S) the transmitter’s button until the indicator turns red. The device will delete all the receivers' connection within the coverage range.

2.3.In W-DMX Receive protocol:

Press and hold (> 3S) the receiver’s button until the indicator turns white. The device would disconnect with the transmitter.
