DMX and Ethernet terminals
All control signals are connected to the data input board PCB3031, located at the top of the
right-hand cabling compartment.
PCB 3031
6.6.1 DMX Connection
– type of cable
Use data cable with two twisted pairs + 1 conductor (can be from a third pair) + overall
screen. Use data cable which is suitable for digital data transmission (EIA 485 / RS 485;
250kBaud). The data cable must meet the DMX512-A specification (ANSI E1.11
– 200x). Do
not use audio cable for DMX, as this has the wrong capacitance and impedance and WILL
NOT reliably transmit DMX signals. The DMX signal uses fairly high frequencies, well above
1000 kHz.
Cable model LIYCY 3 x 2 x 0.35 + shield is suitable for this purpose. Two pairs are used for
data transmission, and one conductor for the 0V (common) GND. The cable shield is
connected to the PE.
Use of Ethernet cables for DMX
It is allowed to use Cat5 (or higher) STP and FTP Ethernet cable for DMX.
STP = shielded twisted pair.
FTP = foil twisted pair.
UTP = unshielded twisted pair.
WARNING: UTP Ethernet cable is not suitable for DMX.
Each EURODIM Twin Tech processor is equipped with two physical DMX inputs, and one
Ethernet port. For cabinets
with optional ‘instant back-up’, each processor has its own
independent data connectors.
Identification of the ports
The DMX ports of the top processor (Processor No. 1) are identified CPU1
–DMXA and
CPU1
–DMXB.
The DMX ports of the optional second processor (Processor No. 2) are identified CPU2
–
DMXA and CPU2
–DMXB.
Each DMX port has an Input and a through (link).
All pin numbering information is also indicated on the data port PCB3031.
