RS422/RS485 to 4 RS232 ; 4 RS422/RS485 Converter Splitter :LDA-108UDP

The Milestone LDA-108UDP 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-8 RS232 to RS422/RS485 Signal Amplifier & Distribution Hub: Converts and amplifies a single RS232 master input signal into eight independent, isolated RS422/RS485 output channels for reliable long-distance data transmission.

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

• Optoelectronic Isolation & Surge Protection: Built-in optical isolation and transient suppression protect host controllers and connected field devices from electrical noise, power spikes, and ground loops.

• Automatic Data Direction & Baud Rate Control: Features hardware auto-baud detection and automatic data direction management, eliminating the need for software-driven RTS/CTS flow control lines.

• Front-Panel LED Diagnostics: Equipped with clear status LEDs for Power, Master Transmit (TX), and individual Receive (RX1–RX8) channels to allow fast, real-time signal and connection monitoring.

• Industrial-Grade Metal Enclosure: Housed in a durable metal chassis engineered for continuous 24/7 operation in factory control panels, SCADA networks, and complex industrial automation systems.

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-108UDP 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.
