This DataPro male-female passthrough adaptor will cross an uncrossed signal or uncross a crossed signal, thereby inverting the transmit/receive pairs on an RS232-wired 25-pin cable.

When connecting from a device to a modem, an asynchronous cable is needed. When connecting two devices directly to each other, a "null-modem" crossover cable is needed. If you have the wrong cable, cross it over with this coupler.
