Connecting to RS232 interface
The transmission rate (in baud) of the serial interface is de-
pendent on the length of the cable
.
Values between 1200 and
115200 Bd may be set (the PC program InfraWin accepts
maximum 38400 Bd).
The baud rate has to be reduced by 50% when the transmis-
sion distance is doubled (see also 9.9 Baud rate).
Typical cable length for RS232 at 19200 Bd is 7 m.

Connecting to RS485 interface
The transmission rate (in baud) of the serial interface is dependent on the length of the cable
.
Values be-
tween 1200 and 115200 Bd may be set (the PC program InfraWin accepts maximum 38400 Bd).
Typical cable length for RS485 at 19200 Bd is 2 km. The baud rate has to be reduced by 50% when the
transmission distance is doubled (see also 9.9 Baud rate).

Connection of additional analyzing devices
Additional analyzing instruments, for
example a LED digital display in-
strument only needs to be connected
to a power supply and the analog
outputs from the pyrometer. Another
Instruments like a controller or printer
can be connected to the display in
series as shown above (total load of
resistance max. 500 Ohm).

Converter
To fix the converter, 2 drill holes for screws
with 4 mm diameter are to reach after remov-
ing the cover.
Note: Only operate the device for a
prolonged period of time when it is
closed! After setting the parameters,
replace the housing cover immediately to
prevent dirt from entering the device and to
meet the electromagnetic requirements (EMV).
