Wiring
2.1 Cabling
The Color Block utilises an XLR4 cable system. This is used to supply power and control data.
Pin 1 = 0VDC, pin 2 = control minus, pin 3 = control plus, pin 4 = +48VDC. The chassis should
be ground bonded.
Only genuine Tourflex Datasafe cable is recommended for use with the Color Block system.
Damage will occur if power connections short-circuit to data or ground shield connections.
When assembling XLR4 cables, heat shrink should be used on each individual data pin and the
drain wire to prevent short circuits.
A maximum of five daisy-chained Color Block DB4 fixtures can be connected to each XLR4
output. Return lines are not
required. The total cable length of each chain must not exceed
60m/200ft.
