I. Introduction
Wireless DMX Transceiver is proprietary system to provide the wireless network communication
(peer-to-peer or peer-to-many) for DMX512 devices and systems. The 2.4GHz broadcasting function allows
the DMX console to send the DMX512 commands to the DMX512 device simultaneously. The Wireless DMX
Transceiver can be set to be transmitter or receiver. The data length and the sampling frequency can be
adjusted. The communication frequency for RF transmission can also be adjusted in order to prevent the
interference problem. It is a wireless, user friendly, plug and play system for all DMX applications in order to
reduce the installation cost and effort.
II. Description
Product Features:
1. DMX-512 communication for DMX console and Moving Head
2. One-to-Many wireless communication between DMX console Transceiver and Moving Head
Transceivers
3. Wireless DMX Transceiver is interference-free from other wireless devices in the 2.45 GHz
band such as W-LAN and Bluetooth
4. Wireless DMX Transceiver uses Direct Sequence Spread Spectrum and there are 16 frequency
channels for wireless DMX transceiver to set the transmission frequency and receiving
frequency.
9/27/2007 - User Manual - Wireless DMX Moving Head Transceiver V4.1a.doc -
5. The communication distance between DMX Console Transceiver and Moving Head Transceiver
is around 20m to 30m line-of-sight.
6. One DMX Transmitter (TX) supports up to 512 DMX channels (one universe) in the same
2.4GHz frequency channel. Up to 16 DMX universes (8192 DMX channels) can be controlled at
the same time when all the 2.4GHz frequency channels (16 frequency channels) are occupied.
7. Four data lengths can be selected (from 128bytes, 256bytes, 384bytes and 512bytes) which
allow different sampling frequencies (from 13Hz, 9Hz, 6Hz and 5Hz)
Setting of TX and RX:
Figure 2: Wireless DMX Transceiver for DMX Console and Target Devices
The Wireless DMX Transceiver can be set to be transmitter (TX) for DMX console or receiver (RX) for
the DMX devices such as moving head, spot light and fogger machine etc. Users can use magic tape to set
the DMX Transceiver on devices. In order to maximize the transmitting power; the top surface of TX must
face the top surface of RX. (As shown in Figure 2)

Setting of Frequency:
The Wireless DMX Transceiver allows you to select up to 16 transmission frequencies in order to
prevent the interference problem. The Dip switch setting is in binary digit. The most LEFT hand side is LSB
(least significant bit) and the most RIGHT hand side is MSB (most significant bit). Put the switch up to set the
digit to 1 and down to set the digital to 0
Figure 4: Top view of Wireless DMX Transceiver – Setting the Frequency Channel
Here are the examples on how to set the frequency channels:
The value is ‘0000’ = channel 0
Note that the frequencies for the TX and RX must be the same!
The value is ‘1010’ = channel 10
The value is ‘1111’ = channel 15

Setting of Data length / Sampling rate:
Figure 5: Top view of Wireless DMX Transceiver – Selection of Data Rate
The Wireless DMX Transceiver provides four different data rates (5Hz, 6Hz, 9Hz and 13Hz) for different
data length requirement. More data will offer less data rate. The setting is similar to the frequency setting in
binary. The LEFT hand side is LSB (least significant bit) and the RIGHT hand side is MSB (most significant
bit). Put the switch up to set the digit to 1 and down to set the digital to 0. Here are the examples for the
setting for the data rates:
The value is ‘00’
=> lowest data rate
(13 data/sec)
=> highest data length
(128 Bytes/data)
Note that:
1. If many DMX devices are used in the DMX network, such as 50 moving heads are controlled by 1
DMX console and each DMX moving head needs 10 bytes. Thus, 500 bytes data is needed for the
transmission. In this case, the 5 data/sec data rate can be selected.
2. If not many DMX devices are used in the DMX network, such as 30 fogger machines are controlled
by 1 DMX console and each DMX fogger machine needs 1 bytes. Thus, 30 bytes data is needed
for the transmission. In this case, the 13 data/sec data rate can be selected.
3. If more DMX devices are used in the DMX network, such as 20 moving heads and 10 fogger
machines are controlled by 1 DMX console and each DMX moving head needs 10 bytes and each
DMX fogger machine needs 1 byte. Thus, 210 bytes data is needed for the transmission. In this
case, the 9 data/sec data rate can be selected.
4. The data rate will affect the response time of the machine. However, the 2.4GHz broadcasting
function of the Wireless DMX Transceiver allows the DMX console to send the DMX512

commands to the DMX512 device simultaneously. No inconsistent between the receivers and
DMX devices.
Setup of the system:
1. Install the device on a plane surface.
Plug the power unit into the socket.

The standard AC/DC transformer is included and allows the power cord to connect the
system to the AC power source. The power source will supply the power to the moving
head and the AC/DC transformer which drive the DC power to the wireless DMX
Transceiver.
Set the TX or RX function for the Wireless DMX Transceiver and the Frequency
channel and the Data Rate.
i. Set TX when it is connected to DMX Console
ii. Set RX when it is connected to DMX devices such as Moving heads, fogger
machines or spot lights etc.
