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


shentek releases RS-232 to RS-422/485 3KV Optical Isolation and 600W Surge Converter. It supports Bi-Directional – RS-232 to RS-422 or RS-485, other way is RS-422 or RS-485 to RS-232. It is efficient solution for applying advantages of RS-422/485 to legacy RS-232 Devices. The converter operates with no extra software installation. With simple DIP Switch toggling RS-422 or RS-485 can be selected. 11005 is fully compatible with Serial Com port in PC or Laptop.

Auto RTS Control

Under 1:N communication environment, it is undesirable that multiple devices send data at once, causing electrical collision that leads to an error. In order to prevent this, only one device needs to send data at a time, which means that data I/O control is necessary at certain points. performs automatic toggling by hardware, saving extra programming work.

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.
