2.5 Operation of OCUs and MCUs with Identical System Address
To ensure safe operation, OCUs and MCUs are paired by way of a system address.
This system address is unique and only assigned once by Cattron.
CAUTION
Conflict of Addresses:
Addresses are never repeated and are System Unique.
The user must ensure that the system address and addressing mode is used as designed.
The system address is marked on the OCU and MCU and must match.
In the event of a breach of this undertaking, the user is liable for any resulting damage/loss and
shall indemnify the manufacturer against all third-party liability claims.
3. Why use Remote Control
Cattron Portable Remote Control (PRC) systems deliver the safety and dependability that are required for efficient
industrial control applications such as overhead cranes, conveyors, machines, etc.
A remote-control system enables an operator to be in the safest, most comfortable and most efficient position for
each operation, thereby minimizing risks of illness, injury or material damage and simultaneously boosting
efficiency and productivity.
4. Remote Control Safety
With an OCU and a matching MCU, a machine such as a crane or vehicle can be remotely radio controlled,
avoiding the need for a wired connection between the human interface and the controlled device. Several different
control elements are integrated into the OCU housing so commands to the device securely encode into a radio
transmission. The MCU is then able to receive this transmission, securely decode these commands, and provide
suitable interfaces to drive the machine.
4.1 Radio Transmission and Security
The transmission between the OCU and MCU is performed by means of a secure RF telegram. Regarding the
actual radio frequency that is used it typically depends on the national regulations and the choice of a licensed or
license exempt frequency band.
A specific RF frequency band and channel may have been selected prior to delivery of the system, depending on
the frequency band, a specific number of RF channels will be available within that band. In all cases a clear
unused (unless timesharing with another Cattron system) channel will be required for reliable operation.
The OCU and MCU must operate on the same RF channel in order to be able to communicate.
