RS422/RS485 to 4 RS232 ; 4 RS422/RS485 Converter Splitter : LDA-104UDP
RS422/RS485 to 4 RS232 ; 4 RS422/RS485 Converter Splitter : LDA-104UDP
The Milestone LDA-104UDP is a professional serial converter splitter that takes a single RS422/RS485 signal and distributes it to four RS232 and four RS422/RS485 output ports. Built for AV connectivity and security installations in India, it lets one control source drive multiple devices at the same time over reliable serial links. The unit simplifies point-to-multipoint networking inside control rooms, server racks and industrial panels, where stable data distribution is essential.
Key Features
• 1-to-4 RS232 to RS422/RS485 Amplifier & Distribution Hub: Converts and amplifies a single RS232 master input signal into four independent, isolated RS422/RS485 output channels for reliable long-distance data drive.
• Selectable 2-Wire & 4-Wire Operating Modes: Fully supports both 2-wire half-duplex (RS485) and 4-wire full-duplex (RS422/RS485) operating modes across all output ports via onboard DIP switches or configuration jumpers.
• Optoelectronic Isolation & Transient Suppression: Integrated optical isolation and surge protection protect host controllers and downstream instruments from ground loops, power spikes, and high electrical noise.
• Automatic Data Direction & Baud Sensing: Features automatic hardware flow control and baud rate detection, eliminating the need for software RTS/CTS handshaking lines.
• Front-Panel Visual Status Diagnostics: Equipped with LED status indicators for Power, Master Transmit (TX), and individual Receive (RX1–RX4) channels for fast real-time network and signal troubleshooting.
• Industrial-Grade Metal Housing: Encased in a rugged metal chassis designed for continuous 24/7 reliability in SCADA networks, industrial control panels, and automation setups.
Applications
• PTZ camera and CCTV system control from a single serial source
• Access control and intercom integration across buildings
• Industrial automation and SCADA communication networks
• AV and building management systems requiring multi-port signal distribution
Summary
The Milestone LDA-104UDP converter splitter is a dependable, cost-effective way to expand serial connectivity in professional installations. Its multi-port design and robust build make it a strong choice for integrators who need clean, reliable data distribution across multiple devices.
