● The device features a full-speed USB device interface, compatible with USB v2.0.
● It emulates standard serial ports for upgrading existing peripheral devices or adding additional serial ports via USB.
● It is fully compatible with serial port applications on Windows operating systems, requiring no modifications.
● The hardware has fully integrated transmit/receive buffers, and the 2-channel RS485 interfaces support communication baud rates ranging from 1200bps to 10Mbps.
● It is suitable for operating systems such as Win98/2K/XP, WIN10/WIN11 32/64-bit systems.
● The communication cables should be made of shielded twisted pairs with a cross-sectional area of at least 0.5mm copper wire. The maximum communication distances are 3000 meters (4800bps), 2000 meters (9600bps), and 1000 meters (115.2Kbps).
● The minimum number of networked sites is 128, and the maximum number of networked sites is determined by the RS485 input impedance of each site.
● The device is equipped with 5 LED indicators: a red light for power, an orange light for data received on the two serial ports, and a green light for data transmitted on the two serial ports, providing convenient status monitoring.
● The RS485 serial port is equipped with 3KV isolation, ensuring that when exposed to long-term high voltage of AC220V or AC380V, only the RS485 interface is affected, while the USB port and connected devices remain protected.
● The RS485 interface features three-level lightning protection, meeting the GB/T17626.5 (IEC61000-4-5) standards, with a short-circuit current wave of 10/700μs and an open-circuit peak output voltage of 6KV, and an internal resistance of 40Ω.
● Working temperature from -40℃ to +85℃.
● The device has passed 100% burn-in testing.
