The 4X USB to RS485 Communication Module Bidirectional HalfDuplex Serial Line Converter is a fourchannel USBtoRS485 interface that enables bidirectional, halfduplex serial communication on each channel. It connects to a USB host and offers four independent RS485 ports, allowing you to interface multiple devices on a single host with a compact, integrated solution. Key Benefits Four independent RS485 channels: Connect and communicate with four RS485 devices from one USB host. Bidirectional halfduplex on every channel: Enables twoway data exchange while using a single twistedpair line per channel, simplifying wiring. Standard RS485 network compatibility: Works with standard RS485 serial networks, suitable for multidrop and longdistance communication. Compact, integrable form factor: Designed to fit into equipment, lab benches, or test rigs with minimal footprint. USB interface for host connectivity: Provides a straightforward USB connection to a PC or embedded host, facilitating quick setup and use. Efficient multidevice workflow: Reduces cabling complexity and hardware footprint while enabling parallel communications across four channels. Key Attributes Channel count: 4 RS485 ports Interface: USB to RS485 per channel Communication mode: Bidirectional halfduplex on each channel Network type: Standard RS485 serial networks Form factor: Module suitable for integration into equipment or test setups Performance: Fourchannel USBtoRS485 capability enables parallel data exchange across devices Applications and Use Cases Industrial automation: Link and control four RS485 field devices (sensors, actuators, controllers) from a single USBconnected host for monitoring and control. Building management and remote sensing: Gather data from multiple RS485 meters or controllers and centralize via USBconnected systems. Data logging and development testing: Use as a multichannel RS485 interface to capture traffic, test device communication, or develop software against several RS485 endpoints simultaneously. This product provides a straightforward, multichannel USBtoRS485 solution with bidirectional halfduplex communication, suitable for situations where multiple RS485 devices need to be connected and controlled from a single USBenabled host.
