Overview
Extend and centralize serial paging and nurse-call communications with the Alpha Communications MLS-485D Network Controller. Designed for nurse call stations, paging systems and security monitoring networks, the MLS-485D converts RS-232 data to RS-485 to eliminate distance limitations and maintain robust, noise-resistant links. The unit supports up to 31 RS-232 transmit-only ports and allows connected ports to be located as far as 4000' apart, making it ideal for hospitals, long corridors, campuses and surveillance installations. Built-in CTS handshaking prevents simultaneous communication attempts, ensuring orderly flow control and dependable message delivery across your network. Installation is straightforward: MLS-485D units form a network using simple two-pair wiring, cutting cabling cost and deployment time. Housed in a compact black ABS enclosure, the controller fits neatly into low-voltage racks or field enclosures for clean, professional installations. Improve operational reliability for paging, nurse call and security systems—contact our sales team to specify the MLS-485D for your next monitoring or surveillance deployment.
