What is the PAB

PAB is a CAN-Bus-System which allows for extremely secure and interference free data transfer between GHL PAB devices.

The range between the daisy-chained divices can be up to 100 m (300 ft).

PAB devices are:

  • ProfiLux 3 and 4 Controllers
  • Expansion Boxes
  • GHL Dosers
  • Powerbars 6D-PAB, 5.1-PAB, Powerbar 6E-PAB, Powerhub-6D-PAB
  • SMS-Modules

How does the ProfiLux Aquatic Bus work

The system works according to the master-slave principle. The master unit can be a  ProfiLux Controller (starting from model ProfiLux 3) or a Doser Standalone to which all other bus participants can be subordinated as a slave unit.

PAB devices are always connected in series. This means that all PAB devices must be connected to the PAB cables linearly with each other. The first PAB device is connected via a PAB connection cable with one of the PAB ports of the next party. The PAB works bi-directional; this means every PAB jack can be used for input or output. The next participant is connected again at the free PAB port of the previous participant, and so on.

The last device of the PAB therefore always has an unoccupied PAB connection.

Devices with ProfiLux Aquatic Bus – in short PAB – are connected to the corresponding RJ45 sockets.

PAB RJ45 Connection
The PAB provides a line connection via the single PAB participants from one end to the other. A ring or star topology of the PAB bus is not allowed.

Exemplary Connection of PAB Devices

A new device can also be connected during operation. For this, connect simply the device to the free port of the ProfiLux or of a PAB device and establish the power supply.

  • PAB devices must always be linearly connected to each other.
  • The last device on the PAB must always provide a free PAB port.
  • Never connect the last two PAB devices through an additional PAB connection cable.
  • Such a ring connection leads to malfunctioning and is not allowed.
