● The device features a full-speed USB interface, compatible with USB v2.0.
● It emulates a standard serial port, allowing for the upgrade of existing peripheral devices or the addition of extra serial ports via USB.
● The serial port applications on Windows operating systems are fully compatible without any modifications required.
● The hardware includes built-in transmit/receive buffers. The RS485 interface supports communication baud rates from 50bps to 2Mbps, while the RS232 interface supports communication baud rates from 50bps to 256kbps.
● The device automatically selects between RS232 and RS485 interfaces upon connection (cannot be used simultaneously).
● It is compatible with operating systems such as Win98/2K/XP, WIN10/WIN11 (32/64-bit), Linux, MAC OS-9/X, and Android.
● The RS485 communication line requires shielded twisted pair cables with a minimum cross-sectional area of 0.5mm copper, supporting maximum communication distances of 3000 meters (4800bps), 2000 meters (9600bps), and 1000 meters (115.2Kbps).
● The minimum number of networked sites is 128, and the maximum number is determined by the RS485 input impedance of each site.
● It features three LED indicators: power (red), serial data receive (orange), and serial data transmit (green) for convenient status monitoring.
● The USB port is gold-plated, and the device is powered via USB. The operating current is less than 30mA. The USB interface provides protection against electrostatic discharge up to ±15kV (air) and ±8kV (contact), EFT protection up to 40A (5/50ns), and lightning protection up to 5A (8/20us).
● The RS232/485 serial ports are equipped with 3KV isolation. When exposed to long-term high voltages of AC220V or AC380V, only the RS485 interface may be affected, without damaging the USB port or connected devices.
● The RS232/485 interfaces provide three-level lightning protection, meeting the GB/T17626.5 (IEC61000-4-5) standard with a short-circuit current wave of 10/700μs and an open-circuit peak output voltage of 6KV with an internal resistance of 40Ω.
● Working temperature ranging from -40°C to +85°C.
● It has passed 100% burn-in testing.
