CS-428/9 RS232 to RS422/485 Converter

Manufacturer: SystemBase

This product has been replaced by CS-428/9 (AT).

CS-428/9 AT is an interface converter that converts RS232 signal into RS422 or RS485 signal. Since CS-428/9 AT is designed to get power from a PC or other equipment for its operation, it does not require an additional power connection or cabling work.

Its automated opening and closing of input and output terminals eliminate the hassle of toggling into RTS signals required when using existing devices.

Equipped with high-performance surge protector, CS-428/9 AT fends off various electrical shocks delivered through signal lines while using a product. Furthermore, LEDs e.g. Power, Tx and Rx enable a user to check the status of power supply to a converter and conduct transmission/reception tests.
