Hardware Installation

Before installation, please make sure all of peripherals and computers have been turned off. This example of installation is based on 8 port KVM Switch and 16 port KVM Switch have the same installation procedures

• Step 1
  Find a convenient place to put your KVM Switch. Its 19” rack mount form factor makes it ideal stackable on 19” rack. When stacking to a rack, attach the included brackets to the sides of the KVM Switch. Take note of the length of your cables so that your computers, KVM Switch, keyboard, mouse and monitor are distanced properly.

• Step 2
  Connect the monitor to the KVM Switch. Using the attached cable, or the one included with your monitor, connect it to the HD DB-15 female port on the back of the KVM unit labeled with the monitor symbol at the CONSOLE port connector.

• Step 3
  Connect the keyboard to the KVM Switch. If you have an AT type keyboard, you will need an AT to PS/2 adapter.

• Step 4
  Connect the mouse to the KVM Switch.

• Step 5
  Now the PC connections will be made with the monitor (VGA) connections first. Connect a VGA cable (15-pin HDDB Male / Male) with the Male side to both of the PC and the rear panel of the KVM switch to the connector labeled VGA. Repeat this for all PCs.

• Step 6
  Connect the first computer’s mouse cable to the KVM Switch. If using a PS/2 cable, connect one end to the PS/2 mouse port on the computer, and the other end to the PC1 PS/2 mouse port on the back of KVM Switch. If using a serial mouse cable (optional), connect one end to a DB-9 serial port on the computer, and the other end to the PC1 DB-9 serial mouse port on the back of the KVM Switch. If you need Serial DB-9 to PS2 Mini Din 6 pin adapter, please contact your supplier.

• Step 7
  Connect the first computer’s keyboard cable to the KVM Switch. Using another PS/2 cable connect one end to PS/2 keyboard port on the computer, and the other end to the PC1 keyboard port on the back of KVM unit. If your computer has an AT type keyboard port, you will need a PS/2 to AT keyboard adapter.

• Step 8
  Double-check all of the connections. You can check the color of keyboard and mouse connector to make sure the keyboard and mouse cables go to the corect ports.

• Step 9
  Repeat step 5 to 7 for the remainder of the computers.

• Step 10
  Attach the power supply to the KVM unit and plug the other end into an electrical receptacle. Now you will see the LED for Port 1 light up, and you will hear a beep. Switch on your monitor.

NOTE:
Please be remind to plug in power adapter. Although the PCs connected to KVM Switch are able to support enough power to the stand alone switch, KVM Switch still needs a power adapter for daisy chain more banks. If you forget to plug in power adapter on the status of daisy chain, it may cause the unexpected status occurred.

Troubleshooting

1. Ensure that all cables are well seated. Label all of cables with the number for each respective computer to avoid confusion.

2. The recommended VGA cable distance is 5 meters maximum without ghosting and degradation. Normally, the cable length is based on driver capacity of your VGA card. If you need longer VGA cable, please use VGA extender (MAX. 100 feet) to accomplish your applications.

3. The recommended PS2 cable distance is 5 meters maximum. Normally, the cable length is based on driver capacity of your motherboard PS2 port. If you need longer PS2 cable, please use PS2 extender (MAX. 100 feet ) to accomplish your applications.

4. The Power Jack polarity is center positive and the power adapter need be DC12V, 1A or DC9V, 1A.

5. Don’t press any keys on the keyboard while the selected computer is booting up. Otherwise, it might cause the keyboard error or keyboard is not detected at PC side.

6. The computer boot up fine, but keyboard doesn’t work

   • Make sure the keyboard works when directly plugged into the computer.
   • Try a different keyboard, but use only 101, 102 or 104-key keyboard.
   • The Mouse is not detected during PC boot up.
   • Make sure the mouse works when directly plugged into the computer.
   • Make sure the mouse is a true PS/2 mouse. A combo mouse will work just as long as it is set for PS/2 mode with the correct adapter. Try a different mouse.
   • Avoiding moving the mouse or pressing the mouse buttons when switching ports.
   • Avoiding switching ports during shutting down the PC process.
   • When you switch one PC port to another PC port, the best scan time setting need to be set to 5 sec. or more. Normally, the VGA monitor change one resolution mode to another will take one or two seconds. So, the scan time is not recommended to below 5 seconds.

7. The power switch is off, but the switch still works fine or power adapter is unplugged from the switch, but the switch still works fine.
   KVM Switch unit draws the power source from power adapter and all PC’s PS2 port. Some PC’s PS2 port can support enough power for the switch, but some PC’s PS2 port ( like laptop, notebook computer…etc.) is unable to supply enough power for the switch. In order to make sure the system can work steadily, please do not set power switch to off state or remove the power adapter from the switch.
   Although the PCs connected to KVM Switch unit are able to support enough power to the stand alone switch, KVM Switch unit still needs a power adapter for daisy chain more banks.

8. If forgetting the “ password ” you typed, please contact your supplier.
