The combination of industrial automation projects and serial communication wires seems to be a trend at present. The combination of the advantages of serial communication wires and industrial automation projects can better meet people's ever-increasing requirements, and with the reduction of technology and cost, this idea not only has it become practical and easy to implement, but it can also better meet the needs of the market. At present, many manufacturers have seen this. Recently, many manufacturers have launched this product, and the price is getting lower and lower. DT-9003 RS232 to RS485/RS422 converter is a very popular serial port conversion product of this type recently.

DT-9003 RS232 to RS485/RS422 converter adopts the combination design of high-speed logic processing chip and imported chip, which can provide powerful data conversion support, making the support of this serial converter in signal transmission quite stable and reliable , First of all, it can perfectly support long-distance stable transmission of 1200 meters, and it is also a passive bidirectional converter, that is, RS232 to RS485/RS422, and RS485/RS422 to RS232. Then for the power supply, since the DT-9003 RS232 to RS485/RS422 converter internally uses the "RS232 charge pump" drive, it does not need to initialize the 232 serial port to get the power supply, and does not need an external power supply.

In addition, this serial port converter is also quite powerful in data conversion. It can automatically control the direction of data flow, so that it does not need handshake signals such as RTS and DTR, and can ensure that the program written by the converter in RS232 half-duplex mode does not need after changing, it can run in RS485/RS422 mode.

The chip of DT-9003 RS232 to RS485/RS422 converter has an automatic transceiver conversion function inside, the transmission distance can reach 300-115.2Kbps, data transmission without delay, and can ensure faster signal operation. There are four communication methods, point-to-point/two-wire half-duplex, point-to-multipoint/two-wire half-duplex, point-to-multipoint/four-wire full-duplex, point-to-multipoint/four-wire full-duplex, human nature The optimized design allows you to use this product happily.

DT-9003 RS232 to RS485/RS422 converter has positive and negative 15KV electrostatic protection. When the power is on, contact with air discharge will not affect the high-speed transmission of the RS485 interface; it has also passed the 24-hour aging test, and each line has a surge protection of 600W Power, can make your data very safe and stable insertion loss, and let you use this converter very safely.

DT-9003 RS232 to RS485/RS422 converter adopts a high-end and atmospheric matte black horizontal shape. The shell is made of PVS material, and the surface has been finely polished. The relatively small size makes it very convenient to carry and move. The overall feeling is quite noble.

The interfaces at both ends are RS232 and RS485/RS422 binding posts, which are compatible with standard RS232 and RS485/RS422 interfaces, and can connect laptops, desktop hosts and other devices with RS232 interfaces to medical detectors, PLC industrial computers, and access control systems , Industrial controllers, SMS controllers and other devices with RS485/RS422 interfaces are sufficient for normal use by users.

The above is the relevant performance knowledge of the DT-9003 RS232 to RS485/RS422 converter, hope it will be helpful to you!
