Description
The SS100/SS100SiS media converters provide complete signal conversion between RS-232 and RS-422/485, without requiring an external power source. It is a fast and efficient solution to overcome distance limitations of RS232 or for connecting to industrial devices with an RS422/RS485 interface. The converters support both half-duplex 2-wire RS-485 and full-duplex 4-wire RS-422/485, and you could select mode via DIP switch without extra software required. Automatic data direction control is provided for RS-485. In this case, the RS-485 driver is enabled automatically when the circuitry senses the TxD output from the RS-232 signal. This means that no programming effort is required to control the transmission direction of the RS-485 signal.
