Control using the RS-232 port
Controlling the Multivideo 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 Multivideo
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 Multivideo 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).
Figure 9. Examples of 9 pin RS-232 Straight Through and Crossed Cables
Establish a connection to the Multivideo DP switch
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 Multivideo DP.
3. On Windows, use the Windows Control Panel / Device Manager to identify the COM port number. See
instructions and Figure 10. below.
4. Power on the device.
Figure 10. Identifying Serial Ports on Window Device Manager

MultiVideo DP KVM Switch Manual 8
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:
5. Click on the Windows Start button.
6. Click on Control Panel.
7. Click on Device Manager.
8. Click on the arrow next to Ports (COM & LPT).
You should see the name of your adapter and the COM port number in use.
EDID Learning and Programming (HDMI Model Only)
The Multivideo DP features plug-and-play EDID, making the switch easy to implement in virtually any
application. As soon as a user plugs in a monitor, the switch automatically learns and copies the EDID to all
ports. The plug-and-play EDID helps make switching hassle free and simple.
