● Based on FPGA design, it can automatically generate precise RS485 transmit/receive switching enable signals based on the transmitted data. It can automatically detect and control RS-485 data flow, providing superior performance compared to the conventional enable generation method using Schmitt triggers.
● Each RS485 port has a 6kV lightning protection capability, 2.5kV optoelectrical isolation, and is equipped with independent shielded wire ground interfaces and transmit/receive LED indicators. It is powered by a 2500V DC-DC isolated power supply, and the communication signals are isolated using high-speed optocouplers.
● The upstream interface provides one RS232/422/485 and USB interface simultaneously, and the USB interface can supply power.
● The upstream interface is a full-speed USB device interface, compatible with USB v2.0, used for upgrading original serial peripheral devices or adding additional serial ports via USB.
● Serial port applications on Windows operating systems are fully compatible without modification.
● It’s compatible with operating systems: Win98/2K/XP, WIN10/WIN11 32/64-bit systems, Linux, MAC OS-9/X, Android.
● The communication cable should have a cross-sectional area of 0.5mm or more, made of copper, shielded twisted pair. The maximum communication distance is 3000 meters (4800bps), 2000 meters (9600bps), and 1000 meters (115.2Kbps).
● The minimum number of network nodes is 128, and the maximum number of network nodes is determined by the RS485 input impedance of each node.
● In the event of lightning strikes or equipment failures, the problematic network segment will be isolated to ensure the regular operation of other segments.
● The upstream interface RS232/422/485 is optional, with a baud rate range of 0-115200bps.
● It supports a wide range of 9-70V AC and DC power inputs.
● It supports internal isolation and redundant dual power inputs. Power supports overload protection and reverse connection protection.
● It complies with industrial level-four electromagnetic compatibility requirements. Provides strong lightning protection: resistance to lightning strikes, high voltage induction, surge protection, etc.
● Fanless design for efficient heat dissipation, reducing repair time.
● Anodized aluminum alloy housing with IP40-rating can withstand harsh environments. It can be mounted on a rail or wall.
● Operating temperature of -40°C to +85°C.
● The device has passed 100% burn-in testing.
