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 instrucons on how to create an RS-232 connecon between a PC and
the Smart-AVI device.
Use terminal client soware such as the PuTTY to connect to the Smart-AVI device. Make sure to use
communicaon sengs 115200 bps, N, 8, 1, No ow 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 Smart-AVI device 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 through
cable pin-outs are shown below. The standard maximum length for a RS-232 cable is 50 feet. Call our
Smart-AVI Support Engineer if you require more informaon.

1. Connect an RS-232 cable to the RS-232 connector on the PC.
2. Connect the other end of the cable to the RS-232 port of the Smart-AVI device.
3. Use Windows Control Panel / Device Manager to idenfy the Com port number. See instrucons
and Figure 7-2 below.
4. Power on the device.
If you are using a USB to COM port adapter on a Windows PC and need to idenfy the COM port used,
do the following:
1. Click on the start buon.
2. Click on Control Panel.
3. Click on Device Manager.
4. Click on the arrow next to Ports (COM & LPT).
You should see the name of your adapter and the COM port number in use.
