11.2 CellaView via RS485 point-to-point connection
A USB/RS485 converter is needed when working with the RS485 inter-
face. The pyrometer can be directly connected if the PC has an integrat-
ed RS485 Interface board. 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.
Moreover, use a converter with galvanic isolation (e.g. W&T 38211) to
avoid problems with ground loops.
