Autronica 116-EAU-321 Serial Port Communication Board

The Autronica 116-EAU-321 is a serial port communication board, which is required when third party equipment is to be interfaced with AutroSafe via the internal protocol AutroCom. Typical applications are interface to building management systems, paging systems (via the ESPA interface module), or interface to external PLC equipment (via the Modbus converter).

The Autronica EAU-321 features 4 ports with duplicated outputs.
Port 1 and 2 can be used for AutroCom communication, and can provide redundant communication for this.
Port 3 is dedicated to AutroSafe IFG AutroFieldBus communication.
Port 4 is dedicated to AUTROLON network downloading, i.e. configuration files are downloaded to all panels in a distributed system by use of port 4 on the EAU-321 mounted inside the booting panel
Port 1 and 2 can be used for both RS232, RS422 and RS485 interface (defined by means of jumper settings).
Port 3 and 4 are fixed RS232 ports.
