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.
Use terminal client software such as PuTTY to connect to the Smart-AVI device. Make sure to use communication settings 115200 bps, N, 8, 1, and 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 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 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 information.
Examples of 9-pin RS-232 Straight Through and Crossed Cables
Establish a connection to the Smart-AVI device
- Connect an RS-232 cable to the RS-232 connector on the PC.
- Connect the other end of the cable to the RS-232 port of the Smart-AVI device.
- Use Windows Control Panel / Device Manager to identify the Com port number. See instructions and Figure 7-2 below.
- Power on the device.
If you are using a USB to COM port adapter on a Windows PC and need to identify the COM port used, do the following:
- Click on the start button.
- Click on Control Panel.
- Click on Device Manager.
- Click on the arrow next to Ports (COM & LPT).
You should see the name of your adapter and the COM port number in use.
