Designed to replace a legacy Casi M Series 8RP to a single communications port that supports up to 8 externals, 2 wire RS-485 based channels.

The M5 Bridge is one of Mercury’s historic lines of controllers designed for interoperability with legacy third-party access control systems. The M5 Bridge was built from the existing Authentic Mercury controller platform and has been redesigned to fit the specific physical parameters of Casi Micro5 enclosures used in Picture Perfect™, Secure Perfect™, and Facility Commander™ access systems.
