Attaching the system interface to the CX20x0 system

Opening the PCI Express bus cover

The system interfaces for the CX20x0 system are connected via the internal PCI Express bus, which has a protective cap. The cap can be removed with a screwdriver. To this end insert the screwdriver into the recess in the short side (see diagram) and lever off the cap. The bus connector is then accessible, as shown in the diagram.

Once the bus connector is accessible, the module can be attached on the left-hand side.

The module audibly locks into place.

Further modules can be connected to the system in the same way. Once all modules are connected, the system is placed on the DIN rail as a block. For details please refer to the section on DIN rail mounting.

Maximum number of system interfaces Up to four system interfaces can be attached on the left-hand side of the system.
