Needed an easy way to turn my USB/Serial cable into a full null modem, wanted something compact and easy to just install on the wire and forget about. This did the trick, worked exactly as advertise. Wouldn't hesitate to buy it again.
Purchased for use with a 4X2 HDMI full matrix switch. The desktop utility required a working RS232 connection. With cabling/device requirements, an adapter of this configuration was needed. Once installed, however, the utility program still couldn't pick up the RS232 connection. As the switch was not working will enough either, it was returned and the use of this piece no longer mattered.
