Step 4-1 (Remote Console)

Extending your PC console up to 500 feet away:

(1) To make sure the CAT5 cable is straight through type.
(2) Plug one end of the CAT5 cable into RJ-45 connector of PS/2 KVM switch and the other end into KVM CAT5 receiver RJ-45 port.
(3) Connect remote keyboard, mouse and monitor with PS/2-EXTENDER-RECEIVER "KB", "MS" and "Monitor" interface.
(4) Connect CAT5 receiver PC port with PC console port by using 3-in-one KVM cable.

1. Local console and Remote console of KVM Switch will have the same priority to control computer, just like a PC connected to two consoles. The remote console can control both the local PC and remote PC connected to KVM switch; however, the local console can only control the PCs on local side. There will be a conflict, if the local console and remote console access the computer simultaneously. Please don't use local console and

remote console at the same time.

1. When the video signal is foggy or un-cleared on the screen, please check if VGA connector is connected properly, or the VGA resolution is too high for the length of cable being used. If the problem happened at VGA resolution, please shorten the CAT5 cable length or reduce VGA resolution. It is highly recommended to use “optimal CAT5 cable length “to get the best video quality and don’t waste unnecessary CAT5 cable. High VGA resolution is up to 1280X1024 and CAT5 cable length could up to 500 feet approximately.

2. There is a Dip Switch on the rear site of KVM switch. The factory default value is "OFF/OFF" state. When you use the CAT5 cable length is over 300 feet, please set DIP Switch to "ON/ON" state. The other setting likes "ON/OFF" or "OFF/ON" state is reserved for future application.

Step 5

Troubleshooting

1. Make sure that all cables are well connected. Label all of cables with the number for each computer respectively to avoid confusion.
2. To avoid ghosting and degradation, the recommended VGA cable distance is 5 meters maximum. Normally, the cable length is based on driver capacity of your VGA card. If you need longer VGA cable, please use VGA extender to accomplish your applications.
3. The recommended PS/2 cable distance is 5 meters maximum. Normally, the cable length is based on driver capacity of your motherboard PS/2 port. If you need longer PS/2 cable, please use PS/2 extender to accomplish your applications.
4. 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.
5. The computer boot up is fine, but keyboard doesn't work

● Make sure the keyboard works when it is directly plugged into the computer.

● Try a different keyboard, but use only 101, 102 or 104-key keyboard.

1. 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, please set the scan time for 5 sec at least. Normally, it takes one or tow seconds for the VGA monitor to change from one resolution mode to another. So, the scan time is not recommended to be less than 5 seconds.

1. 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 PS/2 port. Some PC's PS/2 port can support enough power for the switch, but some PC's PS/2 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 as 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.

1. If you forget the "password" you typed, please contact your supplier.
2. CAT5 Console Receiver power LED is not ON, to make sure power adapter is connected to KVM CAT5 receiver.
3. No video signal is displayed on the remote monitor.

a. It might happen because VGA cables & connector and CAT5 cable & connector is loosed or disconnected or VGA cable was not attached to computer during boot up process.

b. Or power adapter is not connected to receiver.

1. When video signal is foggy or un-cleared on the screen, please check if VGA connector is connected properly, or if the VGA resolution is too high for the length of cable being used. If the problem happened at VGA resolution, please shorten the CAT5 cable length or reduce VGA resolution. It is highly recommended to use "optimal CAT5 cable length "to get the best video quality and avoid wasting unnecessary CAT5 cable. VGA resolution is up to 1280X1024 and CAT5 cable length could up to 500 feet approximately.
