RS422/RS485 to 4 RS232 ; 4 RS422/RS485 Converter Splitter : LDA-1044UDP
RS422/RS485 to 4 RS232 ; 4 RS422/RS485 Converter Splitter : LDA-1044UDP
The Milestone LDA-1044UDP is a professional serial converter splitter that converts an RS422/RS485 signal into four RS232 and four RS422/RS485 outputs. Purpose-built for security, AV and industrial installations, it allows one host device to communicate with multiple remote peripherals simultaneously, cutting down on cable runs and making control rooms easier to manage. The unit is designed for continuous operation and provides stable, reliable serial communication over long distances.
Key Features
• Dual Protocol Signal Amplification & Splitting (4 RS232 + 4 RS422/RS485): Accepts a single master RS232 input and simultaneously converts, amplifies, and distributes it into 4 independent RS232 output ports and 4 independent RS422/RS485 output channels for multi-device network expansion.
• Selectable 2-Wire & 4-Wire Operating Modes: Fully supports both 2-wire half-duplex (RS485) and 4-wire full-duplex (RS422/RS485) differential serial modes across output channels via onboard DIP switches or jumpers.
• Optoelectronic Isolation & Transient Protection: Integrated optical isolation and surge suppression protect upstream host controllers and connected field devices from high-voltage ground loops, electrical noise, and power spikes.
• Automatic Direction & Baud Rate Control: Equipped with hardware auto-baud rate sensing and automatic data direction management, eliminating the need for software-driven RTS/CTS flow control lines.
• Front-Panel Visual LED Diagnostics: Features dedicated status LED indicators for Power, Master Transmit (TX), and individual Receive (RX) lines for effortless real-time data flow and network monitoring.
• Industrial Heavy-Duty Metal Chassis: Encased in a durable, industrial-grade metal enclosure designed for continuous, reliable 24/7 deployment in SCADA systems, factory automation, and industrial control environments.
Applications
• Connecting multiple DVRs, NVRs and alarm panels to a central control console
• Expanding access control readers and controllers from one serial host port
• Linking industrial machines, sensors and building management devices to a central system
• Integrating POS terminals, ticket printers and LED displays with one communication gateway
Summary
The Milestone LDA-1044UDP is a reliable converter splitter that lets integrators drive multiple RS232 and RS422/RS485 devices from one serial port. Its sturdy design, easy installation and consistent performance make it a cost-effective solution for professional AV and security projects in India.
