Communication
The serial system bus interface RS-485 enables the TROVIS 5572 Room Controller to communi-
cate with a control system (GLT). A complete control system can be implemented using a suit-
able software to visualize the process and to enable communication.
The operation of the controller requires a constant bus link (data cable). The bus line is designed
in an open ring structure to connect individual control equipment. The data cable is connected
at the end of the bus line to the control station over a RS-485/RS-232 converter (e.g. CoRe 01).
The bus connection range (cable length) is maximum 1200 m. A maximum of 128 devices can
be connected in such a segment. Repeaters must be used (for example, CoRe 01) to regenerate
the signal level over long distances or when more than 32 devices are connected to one bus
line. A maximum of 246 devices can be addressed and connected to a bus with 8-bit
addressing.
Caution!
You are required to follow the relevant standards and regulations applicable to light-
ning and overvoltage protection on installing the controller.
A transmitting and/or receiving test can be initiated in the
Communication parameter level:

Description of the parameters that need to be set:
The
Device address is used to identify the controller. An address may only be assigned once
within a system.
The
Baud rate indicates the transfer rate between control system and controller in a bus system.
