ESTABLISHING AN RS-232 CONNECTION
Before you start:
Controlling a Smart-AVI device 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
Smart-AVI device.
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. This Smart-AVI device uses a straight through cable. You can use a Null Modem
Adapter to convert a straight through cable to a crossed cable or a crossed cable to a straight through ca-
ble. Examples of crossed and straight thorough cable pin-outs are shown below. The standard maximum
length for an RS-232 cable is 50 feet. Call our Smart-AVI Support Engineer if you require more informa-
tion.
