RS485 (2-Wire) to RS422 / RS485 (4-Wire) Converter : LD-15UCR

The Milestone LD-15UCR is a serial converter that bridges two-wire RS485 networks to four-wire RS422 or RS485 devices, enabling mixed serial equipment to work together in the same system. It allows installers to connect devices that use different wiring schemes, so a two-wire half-duplex RS485 bus can communicate with four-wire RS422 or RS485 controllers and peripherals. The converter handles the signal conversion transparently, making it a straightforward way to integrate legacy and modern serial hardware in AV, security and industrial data networks.

Key Features
• Converts two-wire RS485 signals to four-wire RS422 or RS485
• Enables half-duplex and full-duplex serial devices to be mixed
• Simplifies integration of differently wired serial equipment
• Supports reliable long-distance serial data transmission
• Compact design for quick installation in existing systems
• Suited to AV, security and industrial serial networking applications

Applications
• Connecting two-wire RS485 devices to four-wire RS422 controllers
• Interfacing mixed serial equipment in security and access control systems
• Integrating legacy serial peripherals in AV installations
• Extending serial communication in industrial automation networks

Summary
The Milestone LD-15UCR is a reliable converter for linking two-wire RS485 buses with four-wire RS422 and RS485 equipment. It is a practical, cost-effective solution for integrators who work with mixed serial interfaces across AV, security and industrial projects in India.
