FUNCTIONALITIES OF THE XCOM-485I
The Xcom-485i module offers the possibility to interact with a Studer Xtender/Vario system with a
third-party device (SCADA system, PLC, etc.) using Modbus RTU on RS-485. The technical
specification of this protocol is available on Studer's web site. This protocol will allow the third-party
device to read and write data, get messages and fully control the Xtender/Vario system. For more

INSTALLATION OF THE XCOM-485I
This device was designed for indoor use only and must under no circumstances be exposed to rain,
snow or any other humid or dusty environment.
As far as possible, reduce exposure to sudden temperature variation: important heat variation may
create undesired and harmful condensation inside the equipment.
Before installing the module, the configuration of the function and the selection of pin out
connection must be achieved.
