Product Description: RS-232 to RS-422/485 Addressable function, 3KV Optical Isolation, 600W Surge Converter. With DIN Rail Kit


shentek releases RS-232 to RS-422/485 Addressable function, 3KV Optical Isolation and 600W Surge Converter.

Most widely used computer systems, PLCs, and measuring equipment and industrial devices, its transmission speed, communication distance, especially the network ability is limited due to unbalanced transmission. The 11007 converter solves this problem, so you can easily build a RS-485/422 multi-drop network with your RS-232 device address assignment for each to communicate more easily.

What is RS485 Echo Mode

The point which is different from the method for RS485 Non-echo mode is that the output signal line by itself is input again to the input signal line. Therefore, it is possible to confirm whether the data sent crashes with the data sent by another terminal or not by reading the echoed data. This operating mode is scarcely used except in some special purposes. On all operation is controlled by hardware circuit so no operation is required by application program.

Using 4-wire RS485

4-Wire RS485 Networking is same as RS422 Multi-Drop Networking. RS422 device is used as master and RS485 device is used as slave in 4-Wire RS485 bus. Although RS422 and RS485 have different electrical standards, most manufacturers make ICs that uses both RS422 and RS485 interface. Therefore, RS422 Multi-Drop and 4-Wire RS485 can be considered equal.
