The RS 232 interface can be checked in a simple way with a connected PC running Microsoft Windows operating
system. With Windows
®
95/98/NT/XP using the program "HyperTerminal".
“HyperTerminal” is no longer part of the operating system in Windows Vista, Windows 7, Windows 8 and Win-
dows 10.
–
With the LAUDA software “Wintherm Plus” (catalogue number LDSM2002) the RS 232 interface can
be addressed.
–
In the Internet there are terminal programs available as freeware. These programs offer similar functions
as “HyperTerminal” (for example PuTTY). Search for “serial port terminal program”.
–
Note the following aspects:
–
The interface operates with one stop bit, no parity bit and with eight data bits.
–
Transfer speed alternatively: 2400, 4800, 9600 (factor setting) or 19200 baud.
–
The RS 232 interface can be operated with or without hardware-handshake (RTS/CTS).
–
The command from the computer must be terminated with a CR, CRLF or LFCR.
–
The response from the thermostat is always terminated with a CRLF.
–
After each command sent to the thermostat, it is necessary to wait for the reply before sending another
command. This ensures that the sequencing of inquiries and answers is clear
CR = Carriage Return (Hex: 0D); LF = Line Feed (Hex: 0A)
Example: Set-value transfer of 30.5 °C to the thermostat

Non-assigned pins should not be connected.
An RS 485 bus requires essentially a bus termination in the form of a terminating network, which provides a de-
fined idle state in the high impedance phases of bus operation. The bus termination is as follows:
F. 3 .2 RS 232 protocol
F. 3 .3 RS 485 connecting lead
