    CS-428/9AT converts RS232 signals to RS422 or 485. It is an efficient solution for applying advantages of RS422/485 to legacy RS232 devices. The converter operates with no extra software installation. With simple DIP switch toggling, RS422 or RS485 can be selected. Also, the product is fully compatible with serial COM port in PC.

    Auto RTS Control (Auto Toggling)

    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. CS-428/9AT 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 CS-428/9AT all operation is controlled by hardware circuit so no operation is required by application program.
