Coemar DR1, Instruction Manual

Page: 6 / 19

Via the XLR5 DMX IN socket, the DR1 receives DMX 512 signal which conforms to the international standard for digital DMX
512signal, regulated by the USITT (U.S Institute of Theatre Technology).
Connection between the DMX 512 controller and the DR1 follows the standard:
Pin 1= Ground (GND)
Pin 2= DATA -
Pin 3= DATA +
Pin 4= Optional - (not connected)
Pin 5= Op (not connected)
Should you have the need to order components for signal connection, the following are the relevant coemar order codes:
ME 4965 (XLR 5 plug)
ME 4966 (XLR 5 socket)
CV 4158 (per metre 2 core screened Ø 0,5 cable)
Connection should be via 2 core screened cable, according to the standard for signal transmission.
The screening should be connected to pin number 1 of the XLR connector and should be isolated from the
metal casing of the connector having regard to polarity.
Connection between the DR1 and any other device should always be made to the international standard:
Connect the DR1 to your DMX universe as shown in the following figure:
All the compatible projectors whose displays you wish to manipulate should be connected via the OUT socket of the DR1 .
You may address up to 250 projectors via the DR1
Should your installation be utilising a dmx splitter, ensure that device has been designed for bi-directional communication and that
it supports the
DMX 512/A. standard.
Coemar recommends the use of a BID.O.S., a powerful bi-directional Opto-isolator.
BID.O.S 6 rack (cod. 660)
BID.O.S 6 truss (cod. 661)
Attention
The system will not function if a mono-directional device is installed between the projectors and the DR1 .
