Fig. 1: RS 232/485 module
10 / 39
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.
1 Cover with holes for fastening screws
2 D-Sub socket, 9-pin
The RS 232/485 module is equipped with a serial interface with 9-pin
D-Sub socket that incorporates a galvanically isolated optocoupler to ensure
electrical isolation and greater immunity to interference. The module is con-
nected to a PC or control station via a 1:1 contacted cable, see Ä Chapter
6.1.1 "Contact assignment RS 232" on page 14.
