CSE485-D interface converters can convert RS232 port to RS485/422 port. It can achieve bidirectional data conversion between serial ports, and the converter can automatically detect the baud rate of the serial port and be convenient to use, the data flow will not loss even if the baud rate of the device changes. It uses I/O circuit to automatically control the direction of data flow, without the handshake signal settings, ensuring compliance with existing communication software and interface hardware. It supports hot swapping and can operate stably even in temperature environments ranging from -40 ℃ to +85 ℃. It can be widely used in indoor and outdoor serial field-bus systems.
