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.
The Color Block PSU-05B delivers power and data via 1 XLR4 output. A maximum of five daisy-
chained Color Block 2 fixtures can be connected to the PSU-05B. Return lines are not required.
The total cable length of each chain must not exceed 60m/200ft.
It is recommended that a maximum of 20m XLR4 cable length should separate adjacent fixture
units as to avoid signal deterioration.
Note: Maximum of 5 Color Block 2 fixtures per cable. No return cables required.
The Color Block PSU-30 delivers power and data via 6 XLR4 outputs. A maximum of five daisy-
chained Color Block 2 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.
It is recommended that a maximum of 20m XLR4 cable length should separate adjacent fixture
units to avoid signal deterioration.
Note: Due to the higher levels of leakage current of the PSU-30 it is important that the XLR4
cables used are manufactured only to the specification detailed above. It is also important that
the cables are not coupled or uncoupled whilst the PSU is powered and that the PSU is
correctly grounded.
