3.0 Power and signal cable
3.1 Power cord
3.2 DMX control cable
3.3 Scroller control cable
The following cables are required for the system to be properly
connected:
Power cord is supplied with the PDU. The Power cord is fitted with a
CEE 22 socket at one end and with a Schuko plug at the other end.
Control cable (not supplied) should be a standard signal cable as per
international DMX512 standards. Belden 1420A, shielded 3 pairs twist
cable is recommended.
The signal pair should occupy one pair. Use the other 2 twist pairs for
"V+" and "COM" line between the PDU and the control desk.
We strongly recommend you reduce the voltage drop in the cable to
as low as possible by using low resistance cable.
The control cable (not supplied) should be of high quality shielded
twist pair type. A good example is Proplex PCCCT, shielded 3 pair twist
cable. The signal pair should occupy one pair. Use the other 2 twist pairs
for "V+" and "COM" line. Since there is a large power supply current
flowing through "V+" and "COM" line between the PDU and the
scroller, we strongly recommend the voltage drop in the cable should be
reduced to minimum.
