CAT5 for long-distance connection 
or multiple-monitor connection
The CAT5 video connection function is for transmitting the 
analog RGB video signal of the computer and the control signal 
of the monitor over a long distance using CAT5 cables. The 
computer can control the monitor via the supplied CAT5 Tx 
BOX. 
CAUTION:
Never connect network devices (such as a hub and a computer 
for L AN) to the CAT5 Tx BOX and the IN and OUT connectors 
of the monitor. If they are connected, the network devices 
themselves, CAT5 Tx BOX, and monitor may be damaged. 
1.  Installation of the USB driver for CAT5 
serial communication control
To connect the computer and the CAT5 Tx BOX via USB 
interface, it is necessary to install the USB driver to the 
computer from the CD-ROM supplied with the monitor. 
(When connecting the computer and the CAT5 Tx BOX via 
RS-232C interface, you don’t have to install the USB driver.) 
OS supported: Windows
® XP, Windows Vista® 
How to install:
1) Installation to Windows
® XP
Start the “PL2303-Driver_XP2K _v
******.exe” fi le in the 
Windows XP folder on the CD-ROM supplied with the monitor 
and install the driver according to the instructions displayed on 
the screen. 
2) Installation to Windows Vista
®
Start the “PL2303_Prolifi c_Vista_******.exe” fi le in the 
Windows VISTA folder on the CD-ROM supplied with the 
monitor and install the driver according to the instructions 
displayed on the screen. 
NOTE:
It is unnecessary to install the USB driver if you don’t use the 
communication control or the USB driver. When the window 
asking you to install the driver is displayed, select cancel.
As for the latest driver for the Windows operating system, 
check the operation of the interface IC “PL-2203” in advance, 
referring to the website of Prolifi c Technology Inc. Prolifi c 
Technology Inc. and Mitsubishi don’t assume any responsibility 
or liability for any damages incurred by the user.

2. Connection of the CAT5 video 
connection function
There are two cases of connection. 
1) Connection to one monitor
1.  Connect the USB connector of the supplied CAT5 Tx BOX 
and that of the computer using a commercially available 
USB cable. (When the USB driver isn’t available, connect an 
RS-232C cable in addition to the USB cable. In this case, 
the RS-232C cable serves for supplying the power to the 
CAT5 Tx BOX.) See page 36.
2.  Connect the RGB input connector (Mini D-SUB 15-pin) of 
the CAT5 Tx BOX and the D-SUB output connector of the 
computer using the signal cable (Mini D-SUB 15-pin to Mini 
D-SUB 15-pin) supplied with the monitor.
3.  Connect the CAT5 output connector (Modular connector 
8-pin) of the CAT5 Tx BOX and the IN connector of the 
RGB5/CAT5 input/output connector (Modular connector 
8-pin) of the monitor using a commercially available CAT5 
cable.
2) Connection to multiple monitors
1.  In addition to the connection described in 2-1), connect the 
OUT connector of the RGB5/CAT5 input/output connector 
(Modular connector 8-pin) of the fi rst monitor and the 
IN connector of the RGB5/CAT5 input/output connector 
(Modular connector 8-pin) of the second monitor using a 
commercially available CAT5 cable.
2.  Connect the third and later monitors in the same way. 
  You can connect up to 5 monitors.

One monitor 150 m / 1920 x 1080 @60 Hz
Multiple monitors200 m / 1920 x 1080 @60 Hz
(Total length of the connected cables)
The lengths given above are based on the actual measurements 
using our standard signal source and the recommended cable 
as follows. Before installation, check the monitor operation in 
advance by connecting it with your computer and cables.
Recommended cable:
8-pin modular connector, straight-through, shielded, Category 
5 or 5e 
3.  Various settings involved in the CAT5 
video connection
In the case of the CAT5 video connection, confi gure the 
following settings displayed on the OSD screen. (See page 47.) 
1) CAT5 CABLE LENGTH
Select the cable length, and the defaults of all the adjustment 
values are automatically determined. 
Select the length that is closest to the actual length of your 
cable. 
2) CAT5 EQ.
Make adjustment so that blur and smear of the displayed letters 
and graphic objects are minimized. 
3) CAT5 RED GAIN/GREEN GAIN/BLUE GAIN
When the displayed image is dark, increase each value. 
When whites aren’t displayed as intended, adjust the RED GAIN 
and BLUE GAIN values.
4) CAT5 RED SKEW/GREEN SKEW/BLUE SKEW
Adjust each value so that the color deviation in the displayed 
letters and graphic objects is minimized.

By connecting multiple LCD monitors and a computer using RS-232C cables (commercially available) or CAT5 cables (commercially 
available), you can control the monitors from the computer via the supplied CAT5 Tx BOX for the following operations:
•  Power ON or OFF
•  Switching between input signals
Connection
Connection by RS-232C  (For RS-232C cable (commercially available), the reverse type cable should be used.) 
•  Before making connections, turn off the personal computer and the monitors. 
•  Start the personal computer fi rst, and then turn on the monitors. (Otherwise, the com port may be unusable.)
CAUTION:
Never connect network devices to the CAT5 IN and OUT connectors. If you do so, they may adversely affect with each other, 
causing breakdown.
NOTE:
If your PC (IBM or IBM compatible) is equipped only with a 25-pin serial port connector, a 25-pin serial port adapter is required.  
Contact your dealer for details.
If you use RS-232C control and CAT5 video connection, please switch the input select switch on CAT5 Tx BOX (on page 12) to 
side “USB” when connecting with USB cable for power supply, or to side “RS232C” when connecting with an auxiliary DC power 
adapter.
