Polycom does not recommend using this straight-through serial cable for 

RS-232 communication from a computer, Crestron system, or AMX device. 

Instead, for RS-232 communication, Polycom recommends using a cross-over 

cable with pin 2 wired to pin 3, pin 3 wired to pin 2, and pin 5 wired to pin 5. The 

other pins are not used.

If you choose to use this straight-through serial cable for RS-232 communication 

from a computer or Crestron system, the 

 is 

required. However, the null modem adapter does not work for RS-232 

communication from AMX devices and causes problems if you try to use it.
