Connecting the communication bus
The devices of the Xtender range are equipped with an own communication bus for data
exchange, configuration and updating of the system. Connection is being made by linking the
devices with the communication cables. One gets then a bus online where a link end must be
activated on the devices on each end, to obtain the configuration of the Figure 3.3 .
Each device is equipped with a switch offering to choose between open "O" and terminated "T".
The devices at the end of the line must be set on "T". The others, receiving two communication
cables, must be set on "O".
By default, the termination is not activated on each product of Studer Innotec SA .

A wrong setting of the link ends can lead to an erratic running of the installation or
impede its updating.
