World's Smallest RS232 Converter

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

Product information

Auto RTS Control (Auto Toggling)
In a 1:N communication environment, it is undesirable that multiple devices send data at the same time, 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-mini performs automatic toggling by hardware, saving extra programming work.
Using 4-Wire RS485
4-Wire RS485 networking is the same as RS422 Multi-Drop networking. The RS422 device is used as master and the RS485 device as slave in a 4-Wire RS485 bus. Although RS422 and RS485 have different electrical standards, most manufacturers make ICs that use both the RS422 and the RS485 interface. Therefore, RS422 Multi-Drop and 4-Wire RS485 can be considered equal.
Although there can be a difference in software that controls them, our device can operate regardless of the application software. In this case, RS422 Multi-Drop mode setting is necessary.
What is RS485 Echo Mode?
The RS485 Echo Mode enables the output signal line to function as the input signal line. With Echo Mode it is not necessary to read the echoed data to confirm whether the sent data crashes with another. Echo Mode is usually used for special purposes only. On CS-428/9AT all operations are controlled by hardware circuits, so no additional conditions are required by the application program.
