CAT5 VGA Extender
ITEM NO.: HTA-TTP111VGA
The VGA Extender allows VGA video signals to be transmitted up to 135 meters via 4-paris CAT5 STP or
UTP cable. Used in pairs, the VGA Extender is used in home or commercial applications as a smart, fast
and cost-effective, eliminates costly and bulky VGA cable, allowing VGA monitors to be connected
extended distances from the PC via standard twisted pair cable. Ideal for classrooms video distribution,
lecture halls, retail kiosks, video information displays, overhead projector systems, PC-training systems,
and tradeshows PC demo systems.
Features:
zPassive device, no power required.
zIncluding 2 units as transmitter and receiver.
zSupports up to 1280x1024 pixels.
zUp to 135 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.
zPerfect for classrooms, lecture halls, tradeshows, video information displays…etc.
Installation:
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.
RJ45 Pin Configuration: TIA/EIA 568B Wiring standard

Switch Setting:
TTP111VGA-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
picture still not normal after adjust the dip switch of HTA-TTP111VGA-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 VGA Extender are dependent on the type of twisted pair
cable and image resolution of the PC’s VGA interface. 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.
Troubleshooting at picture problem:
1. No picture display:
Check Link cable.
Check DIP switch setting.
Check VGA cables 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.
Try to avoid wire 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.

Application Tips to use CAT5 STP cable:
Following is the correct cable connection when use STP cable:
1. STP (shielding twisted pair) Cable.
2. STP (shielding) RJ45 connector with STP cable connection.
If your RJ45 connector is plastic housing (unshielded), then the cable connection
must do the following:
1. The ground cable must pull out around 5-10cm length to connect with VGA Extender’s
ground screw for grounding.
2. Make the ground cable connect to ground screw, then plug RJ45 connector.
