The RAK-LINK provides an isolated link between the RAK4 dimmer units and wired RAKOM products. The unit also includes a heavy duty 15v dc power supply for the RAKOM network. Connection for the CAT5 is by 8 way punch down terminals. This allows for a daisy chain configuration of the RAKOM wired network. Where a ‘star’ or ‘home-run’ configurations are required the use of the RAK-STAR unit is needed. Three RJ11 programming sockets within the unit allows system programming using the RASOFT software suite and connection of other RAKOM accessories such as the WA-BRIDGE interface.
