ONSTRUCTION OF THE DMX TERMINATION
The termination avoids the risk of DMX 512 signals being reflected back along the cable when they
reaches the end of the line:
under certain conditions and with certain cable lengths, this could cause them to cancel the original
signals.
The termination is prepared by soldering a 120Ohm 1/4 W resistor between pins 2 and 3 of the 5-pin
male XLR connector (see diagram).

DMX
Synthesis is the world’s first moving head fixture fitted with wireless DMX as standard. It uses a
technology based on the idea of GSM, with a radius over 500 meters.
It has been widely tested in environments with WiFi, bluetooth, GPRS-UMTS signals, with excellent
results.
If you want to use the wireless DMX protocol instead of the cable, proceed as follows:
For the wireless connection you need a specific transmitter (code 0097035)
Synthesis has 2 menus dedicated to the wireless: 1-WIRELESS LOG OFF and 2-WIRELESS
The procedure to activate the wireless communication is very easy:
1.
Enter the LOG OFF menu and confirm the SET option. This function disables all the
communications previously enabled.
2.
Set the WIRELESS on ON. This will enable a new communication.
3.
Press the LOG key on the Transmitter to connect the receiver placed on the fixture to the
wireless transmitter.
RDM

)
RDM stands for Remote Device Management. This is the colloquial name for the ANSI E1.20 standard
in development at ESTA
.
RDM is intended to allow bi-directional communication over the DMX512
cable. This will occur on the twisted pair connected to pins 2 and 3. This same pair of wires is used
to transmit data from the console to the dimmers or moving lamps.
The large benefit of this approach as opposed to using the spare pins 4 and 5, is that RDM can be
retrofitted to installations wired with single pair cable.
RDM will provide the following benefits:
1.
Ability for the console to set the base address of the lamp. There will no longer be a need for DIP
switches.
2.
Plug and Play. The console will be able to search all the DMX512 devices and then automatically
patch them.
3.
Fixture Personality: it will be possible for the console to use RDM to download personalities direct
from the moving lamp.
4.
RDM devices can be firmware upgraded via the DMX signal.
5.
RDM devices can send status and fault information back to the console.
6.
By allowing bi-directional communication, it will be much easier to mix DMX installation with
sophisticated Ethernet protocols such as Art-Net and ACN.
