This cable is exactly what you need when you only need a simple TX/RX crossover cable and don't have an Allen-Bradley 8-pin Mini DIN cable on hand (or just don't want to use one). It's 5 feet AND shielded as advertised, and it works like a charm in RS232 and DH485 modes (tested with a Keyspan USA-19HS and A-B 1747-UIC, respectively). The pictures more or less speak for themselves; not a single dropped packet. For $7, you could do a helluva lot worse.
