Seco-Larm EVA-RS1 RS-232 to RS-485 Interface Converter

The Seco-Larm EVA-RS1 is a professional-grade RS-232 to RS-485 converter designed for integration within commercial security and life-safety installations. By bridging the gap between RS-232 serial interfaces and RS-485 bus networks, the EVA-RS1 enables system integrators to extend communication runs, interconnect legacy serial devices with modern multi-drop RS-485 infrastructures, and maintain signal integrity across larger installations. As a Seco-Larm component, it is suited for deployment in access control, intrusion detection, and broader building automation environments where reliable serial communication is critical.

Key features & benefits

• RS-232 to RS-485 Protocol Conversion — Converts standard RS-232 serial signals to RS-485 differential signaling, allowing devices with RS-232 ports to communicate over RS-485 bus networks commonly used in commercial security systems.
• Commercial-Grade Build Quality — Manufactured by Seco-Larm, a recognized name in the professional security and life-safety market, the EVA-RS1 is built to meet the demands of permanent commercial installations.
• Simplified System Integration — Enables integrators to connect RS-232 controllers or host systems to multi-drop RS-485 device networks without requiring hardware replacement, preserving existing infrastructure investments.
