VGA Keyboard Mouse CAT5 Extender
ITEM NO.: VKM01
The VGA, Keyboard Mouse CAT5 Extender allows VGA video signals and keyboard mouse to
be transmitted up to 100 meters via 2 x CAT5 STP or UTP cable. Used in pairs, the Extender
is used in home or commercial applications as a smart, fast and cost-effective, eliminates
costly and bulky VGA, keyboard mouse cable. Applications for classroom projector systems,
boardroom systems, collaborative PC systems C-training systems, and tradeshows PC demo
systems and medical information systems.
Features:
VKM01 Keyboard Mouse CAT5 Extender – PS/2 Interface
zExtend VGA and Keyboard mouse over 2 CAT5 UTP cable to instead of VGA cable and
keyboard mouse cable.
zIncluding local and remote units.
zUp to 100 meters via standard 4 pairs CAT5 STP or UTP cable instead of VGA cable.
zTransmitter built in virtual DDC to avoid improperly setting at resolution and frequency.
zTransmitter built in sync mode selection for signal stability.
zReceiver built in sync filter level adjustment for signal stability.
zSupports up to 1280x1024 pixels.
zPassive device, not support VGA DDC protocol.
zPerfect for classrooms, lecture halls, tradeshows, video information displays…etc.
Recommend Cable:
1. CAT5e UTP/STP or Cat6 UTP cable.
2. There are some certain models or brands of monitors with very high demand at
sync-sensitive, recommend use STP (shielding twisted pair) cable to instead of UTP
(unshielded twisted pair) cable.

Switch Setting:
VKM01-T Sync Mode Select
====================
←Mode 1
→Mode 2
1. For new type monitors, such like over 17” LCD Monitor, recommends setting at mode 1
for the best stability. If the picture not normal, then switch to Mode 2.
2. For old type monitors, such like CRT or under 17” LCD Monitor, recommend setting at
mode 2. If the picture still not normal after adjust the dip switch of VKM01-R. Then
please use STP (shielding twisted pair) cable.

Sync Filter is designed for using UTP CAT5 cabling.
Sync Filter level adjustment is to add the sync stability, but not adjust picture quality or
eliminate skew.
Since different brand monitor have different setting, so there is no recommended setting.
Please adjust the level based on picture stability. If no picture display or picture not stable,
then please use STP cable.
Caution:
1. The wiring must be away from electro magnetic equipment, i.e. microwave, wireless, hi voltage
cable…etc.
2. The maximum distances supported by the VGAExtender are dependent on the type of twisted pair
cable and image resolution of the PC’s VGAinterface. Make sure that the maximum
recommended operational distances have not been exceeded.
3. All wiring is “straight-through” twisted pair cable, not being used for other LAN or telephone
equipment.
4. Do not connect the VGA Extender to a telecommunication outlet wired to unrelated equipment.
5. If the keyboard mouse work abnormal, please reverse the cable of keyboard mouse.

Troubleshooting at picture problem:
1. No picture display:
Check Link cable.
Check DIP switch setting.
Check VGA cable connect.
Change the resolution or frequency.
Change Link cable for STP cable.
2. Picture not stable or disappear intermittence or no picture display:
Check DIP switch setting.
Change the resolution or frequency.
Wiring away from electro magnetic equipments.
Change Link cable for STP cable.
3. Picture tilt:
Check DIP switch setting.
Change the resolution or frequency.
Change Link cable for STP cable.
