RS485 interfaces certified with EN 50131-1 Grade 4
RS485
Industrial LAN-RING switches, miniLAN-4B2 converters and xDW-S-4C optical converters with RS485 ports are certified for the interconnection of security systems. In particular, the IP solution with LAN-RING switches and miniILAN converters is very innovative in its solution. Thanks to the separation of the network traffic of the different systems by VLANs and QoS and the possibility of detailed monitoring of all data connections, it can be considered a secure solution that meets the requirements of EN 50131-1 Level 3 and 4, which are verified every three years by an independent testing laboratory.

VLAN and QoS settings
For security reasons, all LAN-RING switches support extended VLAN management, which provides separate VLANs for:
- management
- RS485 traffic (EZS, PIDS, ACS, automation)
- IO transmission
- cameras, servers, etc.
Data in the VLAN can be assigned different priorities according to the QoS standard. As a result, data from the RS485 ports does not reach the FE/GE ports and is transmitted with the highest priority. Swicthe has been tested with DOMINUS, GALAXY and SPC alarm systems as a transmission system for control panels with security level 3 or 4.
Other cyber security measures
- Installation in enclosures with tamper detection
- Backup power supply
- Monitoring of all data connections via SNMPv3
