USB to Serial Adapter, USB to 422 485 PRO Serial Port Converter Module with DB9 Male Connector USB B Interface and surmount Board LED Lights for Multi Kind Control Devices

Function:Industrial grade USB to 485/422 bidirectional converter, using original FT232 and SP3485 chips. Due to its stable communication performance, it is an ideal choice for industrial control equipment and/or applications with high communication requirements.
Comprehensive conservation:The USB to 422/485 converter has onboard resettable fuse and conservation diode to ensure stable current/voltage output, has over-current/over-voltage conservation function, and enhances anti-vibration performance.
Auto Transceive Circuit:This serial port adapter has built-in automatic transmit/receive conversion circuitry, eliminating the need for manual direction control. The device automatically handles data streams in real time, enabling seamless communication, reducing latency, and minimizing user setup time.
Safe Connectivity:Designed with USB-B input and 5.0mm pluggable terminals, the module features fully isolated power and signal paths. This ensures a clear communication line and protects your device from electrical noise, crosstalk, or unstable power supply due to different ground potentials.
Real-Time Status Monitoring:Equipped with dual onboard LED indicators, users can clearly monitor signal direction - from USB to RS485/RS422 and vice versa. These intuitive indicators provide helpful diagnostic feedback during testing or troubleshooting, streamlining workflow in both field and lab environments.
