2.2 Cabling
The Color Block 2 system utilises an XLR 4-pin 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 drain wire should be connected to the chassis of the XLR.

Only genuine Tourflex Datasafe cable is recommended for use with the Color Block 2 system. Damage will occur if power
connections short-circuit to data or ground shield connections. When assembling XLR4-pin cables, heat shrink should be
used on each individual data pin and the drain wire to prevent short circuits.
