Need to connect more than one RS232 device to a computer at a time? 

The addressable RS232 to RS485 converter allows this.  Each device can be individually selected and the computer or PLC talks to that device.

STX provides a range of high-performance industrial converters for communication over RS422, RS485 or RS232.  Most converters arefully optically isolated.  Try our ever-popular inline 5001, or the DIN-railmountable 5251 RS232-485 converters, which detect the baud rate automatically.
