  • Page 10: Device Description

    The RS 232/485 module is designed for installation in constant temperature equipment that supports the serial interface. The RS 232/485 interface allows the user to activate constant temperature equipment via the LAUDA command set (for example, control station). Combining the RS 232/485 interface with a Profibus interface is only permitted in conjunction with the Command remote control, whose RS 232/485 interface can be used independently.
