RS485 / RS422 Repeater (1 In & 1 Out, Isolated) : LD-15UR

The Milestone LD-15UR is an isolated RS485/RS422 repeater with one input and one output, designed to regenerate and clean serial data signals so they can travel over longer cable runs without degradation. Isolation between the ports helps protect connected equipment from ground loops and electrical noise, which is common in security, access control and industrial installations. The repeater sits directly in a serial link and re-drives a clean copy of the signal to the next segment of the network.

Key Features
• Regenerates RS485 and RS422 serial signals for extended cable lengths
• Provides one input and one output for simple in-line installation
• Isolated ports help prevent ground loops and signal interference
• Extends multi-drop RS485 networks segment by segment
• Supports both RS422 and RS485 line standards
• Compact design that is easy to install between connected devices

Applications
• Extending RS485 bus runs in access control and security systems
• Regenerating serial data over long cable runs in AV installations
• Breaking up multi-drop RS485 networks to improve signal quality
• Connecting serial equipment in electrically noisy environments

Summary
The Milestone LD-15UR is a dependable, isolated repeater for extending RS485 and RS422 serial links in professional AV, security and industrial installations. Its simple one-in, one-out design and signal regeneration make it an essential component for reliable long-distance data communication.
