232 port
Controlling the Vista DP via RS-232 requires an RS-232 card installed on your computer or a USB to RS-232
adapter. Below are instructions on how to create an RS-232 connection between a PC and the Vista DP switch
Use a terminal client software to connect the host PC or notebook to the switch. Make sure to use
communication settings 9600 bps, N, 8, 1 No flow control.
Check the device and your PC to determine if you need a male to male or a male to female cable and how long
it needs to be. The Vista DP requires a straight through cable. You can use a Null Modem Adapter to convert a
crossed cable to a straight through cable. Examples of crossed and straight thorough cable pin-outs are shown
below. The standard maximum length for an RS-232 cable is 50 feet (15 meters).
