The serial converter XS013-422/485 launched by Shenzhen Xallcom Technology Co., Ltd. is designed to achieve active isolation conversion from RS-232 to RS-485/422. It is based on FPGA and powered by a 2500V isolation voltage DC-DC isolation power supply. It does not use serial port stealing technology and uses high-speed optocoupler isolation for communication signals. The device comes with circuit short circuit and data error detection functions. The RS485/422 interface has three-level lightning protection and a communication distance of up to 1800 meters, which is widely used in complex industrial systems.

Product characteristics

Based on FPGA design, it can automatically generate accurate RS485 transceiver switching enable signals according to the transmitted data, and can automatically detect and control

The RS-485 data stream has much better performance than the enable generation method of ordinary Schmitt triggers;

Unique interface adaptive technology, no need for switch settings, freely switch between RS-485/RS-422 interfaces;

Equipped with circuit short circuit detection and data error detection functions, it can detect A-B short circuits in RS485 or T+and T - short circuits in RS422

The road and R+and R - are short circuited, with indicator lights indicating, and can detect receiving data errors (data received when certain nodes fail)

The longest continuous zero time greater than the minimum baud rate (300);

RS232-RS485/422 baud rate 300-115.2K and 300-921K adaptive products are available for selection;

Adopting an isolated voltage 2500V DC-DC power supply, without using serial port power theft, improves the applicability of the equipment, and uses high-speed communication signals
