INTRODUCTION
The ST-C5USBV USB Extender is designed to enable the relocation of a monitor, USB keyboard, and USB mouse from a USB
CPU or NTI USB KVM switch by as much as 1000 feet via CAT5 cable in addition to having a monitor, USB keyboard, and USB
mouse connected locally. It is extremely simple to install and has been thoroughly tested to insure reliable performance. Through
the use of Category 5 shielded or unshielded twisted-pair cable (STP/UTP) or Category 6 unshielded twisted-pair cable (UTP), it is
possible to economically increase the flexibility of a computer system.

PREPARATION FOR INSTALLATION
•A location should be chosen for the monitor, mouse, and keyboard that also has space to mount the Remote Unit within the
distance provided by the cables from the monitor, mouse, and keyboard. If extension cables are needed, contact NTI for the
cables required. If a local user will be connected, a proper location must be chosen for these devices too.
•The CAT5 cable(s) must be run to the locations where the Remote and Local Units will be placed. Be careful to route the
cables away from any sources of magnetic fields or electrical interference that might reduce the quality of the video signal
(i.e. AC motors, welding equipment, etc.). NOTE: If CAT5 cable is already installed in the wall and there are RJ45 wall
outlets, it will be necessary to obtain male-to-male straight through connection cables long enough to reach from the wall
outlets to the mounting locations of the Remote and Local Units.
•A properly grounded, polarized, and preferably surge-protected 120V or 240V electrical outlet (depending on the AC adapter
being used) must be installed close enough to the mounting location of the Remote Unit and monitor to plug them into.
•All cables should be installed in a fashion that will avoid stress on their connections to the equipment. Extended lengths of
cable hanging from a connection may interfere with the quality of that connection. Secure cables as needed to prevent this.
•Properly shut down and disconnect the power of the CPU and monitor. Disconnect the monitor, keyboard, and mouse. If
other equipment is involved whose connections are being interrupted, be sure to refer to the instruction manuals for that
equipment for proper disconnection and re-connection procedures before proceeding.

SETUP MENU
The Setup Menu is an On Screen Display (OSD) menu that allows users to change the configuration of the ST-C5USBV USB
Extender. The following configuration changes can be made:
•Video Adjustments- for adjusting video resolution based on varying cable lengths
•Port Configuration- for adjusting compatibility with MAC versus PC and SUN CPUs
•DDC Update- for updating DDC information between the monitor and the Extender
To access the Setup Menu, simultaneously press the left and right <Shift> keys on the keyboard. The menu in Figure 4 will
appear.
Note: The OSD menu is only accessible from the Remote Unit.
Figure 6- Setup Menu
Function: Keys:
Go to Video Adjustments screen Press <V>
Go to Port Configuration screen Press <P>
Update DDC information Press <D>
Exit Setup Menu Press <Esc>
Note: The window can be moved across the screen by moving the mouse.
Video Adjustment Screen
Video quality adjustment is done automatically to assure the image is as clear as possible. However, due to the different
twisting rates of each pair of wires in the CAT5 cable, variations in the signal delays between the red, green, and blue channels
will occur when the cable is longer than 400 feet. The variations could result in poor image convergence (i.e. instead of a white
vertical line the user will see three vertical lines: red, green, and blue). These variations may be adjusted by changing the
settings in the first three horizontal scroll bars. Changing the settings will vary the timing of the signals and ultimately balance
them out.
Figure 7- Video Adjustment Screen

10
Function: Keys:
To move between the scroll bars Press <Up Arrow> or <Down Arrow>, the selected scrollbar will
have a red label
To adjust the scroll bar setting Press <Left Arrow> or <Right Arrow>
Save changes and exit menu Press <Enter>
Exit menu without saving Press <Esc>
The "RGB" scroll bar is used for fine video quality adjustment of all colors. This allows the user to "fine tune" the quality of the
adjusted video.
To verify if such an adjustment is actually needed, open an application with a white window (i.e. Microsoft Word) and move the
window to the right side of the screen to create a white-to-black transition. If a colored vertical line can be seen at the edge of
the white window the adjustment may be needed. According to the color of the line, change the setting of the corresponding
horizontal scroll bar until a clean white-to-black transition is obtained.
Note: For additional quality adjustment, it may be necessary to adjust the brightness and contrast settings of the
monitor.
Port Configuration Screen
Port Configuration enables the user to configure the Local Unit to be connected to a MAC CPU for passing mouse information
to the MAC CPU. This is useful when the user wants to use mouse drivers provided by the mouse vendor, which allows the use of
programmable functions for each mouse button. The Local Unit can be configured whenever necessary.
NOTE: When the port is connected to a PC or SUN CPU, the configuration should be at the default setting of "W:
Computer is not Mac".
Figure 8- Port Configuration Screen
Function: Keys:
Configure for connection to MAC CPU Press <M> or <Up Arrow>
Configure for connection to PC or SUN CPU (default) Press <W> or <Down Arrow>
Save changes and exit Port Configuration Press <Enter>
Exit Port Configuration without saving Press <Esc>
The corresponding check-box will reflect the port configuration. After setting, the configuration is stored in memory and will be
retrieved whenever the ST-C5USBV Extender is powered ON.

11
DDC Update
DDC information allows the CPU to automatically select the optimal resolution for your monitor. Updating the DDC information is
to be done at initial power-ON of the ST-C5USBV Extender or whenever a different monitor is connected to the Extender. Both
the Local and Remote Units must be powered in order to update the DDC information.
Pressing D from the Setup Menu (page 9) will instruct the ST-C5USBV USB KVM Extender to read the DDC information from the
monitor and store it in memory. A progress bar will show the status of the update operation. The OSD will return to the Setup
Menu once the update is complete. It will be necessary to restart the CPU after updating the DDC information.
Attention: Some graphics cards will not send a video signal to the monitor until it has received the DDC information from the
monitor. In this case, the monitor may not display anything until the DDC information is read. This may occur if this is the first
time the monitor is being connected to the Extender. The DDC information must be updated in the Extender to achieve video.
To update the DDC information without video;
1. With everything connected, power ON the CPU, Remote Unit, the Local Unit, and the monitor.
2. Press the left and right <Shift> keys on the Remote keyboard to get into Setup Menu. (The OSD may not
be visible.) The Green Communication LED on the ST-C5USBV RJ45 connector should stop blinking.
3. Press <D> to update DDC information. The Green Communication LED will blink for 2-3
seconds. Wait until it stops blinking.
4. Press <Esc> to exit the Setup Menu.
5. Restart the CPU.
