The BLACK BOX? RS-232<–>RS-422/449 Interface Converter is ideal for 
converting sync and async RS-422 interfaces to RS-232. It converts all
 commonly used signals for RS-232 to RS-422/RS-449 bidirectionally.

Setup is super easy, too. To configure, just move the jumpers. Set the 
converter for RS-422 data  equipment (DCE) to RS-232 data
terminal equipment (DTE) or RS-232 DCE to RS-422 DTE.

The converter is designed to operate with one port configured as DTE
and the other as DCE. However, it’s designed to function with both
ports configured as DTE or DCE when operating in sync mode.
