4.7. COMMUNICATION PORTS
Astra-8945 Pro Control Panel may be connected to a PC via 3 different communication
ports:

built-in RS-485 interface of TIA/EIA-485-A standard;

additional main RS-485 interfaces of TIA/EIA-485-A standard implemented by
means of universal outputs of A or B slot provided Astra-RS-485 module is in-
stalled;

LAN interface implemented by means of universal outputs of A or B slot provid-
ed Astra-LAN module is installed;

USB interface.
By means of any of these interfaces the Control Panel may be connected to a PC for
system setting and monitoring. The first connection is available only via USB. Then you
are free to change communication port.
We recommend RS-485 or LAN interface for continuous system monitoring. The Astra-
8945 Pro housing design doesn’t allow connection to PC via USB unless the cover is
removed.
For more details, please, refer to Paragraph 7.4. of this Guide.
