RS422/RS485 to 4 RS232 ; 4 RS422/RS485 Converter Splitter : LDA-116UDRMP

The Milestone LDA-116UDRMP is a high-performance RS422/RS485 to RS232 converter splitter designed to fan out one serial port into four RS232 and four RS422/RS485 connections. Ideal for system integrators working on security and AV projects, it enables a single controller to exchange data with several distant devices, reducing installation complexity and keeping wiring organised. Built for dependable long-term duty, the unit maintains stable serial communication over extended cable lengths.

Key Features

• 1-to-16 RS232 to RS422/RS485 Amplifier & Distribution Hub: Converts and amplifies a single RS232 master input signal into sixteen independent, isolated RS422 or RS485 output channels for large-scale industrial data distribution networks.

• 19-Inch Rack-Mount Chassis (RMP): Enclosed in a standardized rack-mountable (RMP) industrial metal housing designed to fit standard 19-inch equipment racks in central control rooms, server closets, and SCADA centers.

• Selectable 2-Wire & 4-Wire Operating Modes: Fully supports both 2-wire half-duplex (RS485) and 4-wire full-duplex (RS422/RS485) communication modes across all 16 output ports via onboard DIP switches or configuration jumpers.

• Optoelectronic Isolation & Transient Suppression: Integrated optical isolation and surge protection safeguard upstream controllers and downstream field devices against high-voltage ground loops, electrical noise, and power spikes.

• Automatic Data Direction & Baud Control: Features automatic hardware flow control and baud rate sensing, eliminating the need for software-driven RTS/CTS handshaking lines.

• Comprehensive Diagnostic LED Panel: Equipped with clear front-panel LED indicators for Power, Master Transmit (TX), and individual Receive (RX1–RX16) channels for rapid real-time status and data traffic monitoring.

Applications
• Feeding serial video and alarm data from multiple DVRs and NVRs to one monitoring console
• Expanding access control systems across multiple readers and door controllers
• Interfacing PLCs, meters and building automation panels with a central host
• Connecting multiple serial terminals, printers and display systems to one gateway

Summary
The Milestone LDA-116UDRMP delivers a simple, reliable way to manage several RS232 and RS422/RS485 devices from a single serial port. With robust construction, tidy wiring and dependable performance, it is an excellent value choice for professional installations across India.
