Caution !
A USB/RS485 converter is needed when working with the RS485 inter-
face. The distance between pyrometer and PC can be up to 1200 m.
In order to prevent reflections on the RS485 connection, it is absolutely
necessary to terminate the connection at the pyrometer and at the con-
verter. The termination is integrated in the pyrometer and is active when
delivered from the factory.
When using a terminal connection via the RS485 interface, Cel-
laView cannot be used via the RS485 interface any longer.
