VGA135 VGA CAT5 Extender
Thank you for your purchase of the VGA135 VGA CAT5 extender. This VGA Extender allows VGA video si nals to transmit up to
328’ (100m) via 4 pairs of CAT5 STP or UTP cable. The VGA135 can be used in a home or commercial application as a smart,
fast, and cost-effective alternative as it replaces costly and bulky VGA cable. VGA135 is ideal for classroom video distribution,
lecture halls, retail kiosks, video information displays, overhead projector systems, PC-trainin systems, and tradeshows.
FEATURES
•Passive device, no power required.
•Includes transmitter and receiver.
•Resolution up to 1920x1080 pixels.
•Up to 328’ (100m) via standard 4 pairs CAT5 STP or UTP cable
•Replaces costly VGA cable with less expensive UTP cable.
•Transmitter has built in virtual DDC to avoid improper settin s of resolution and frequency.
•Transmitter has built in sync mode selection for si nal stability.
•Receiver has built in sync filter level adjustment for si nal stability.

TRANSMISSION DISTANCE CHART
RECOMMENDED CABLE
1. CAT5e UTP/STP or CAT6 UTP cable.
2. There are some monitor models with very hi h sync-sensitive demand. For these units, it’s recommended to use STP
(shieldin twisted pair) cable instead of UTP (unshielded twisted pair).
RJ45 PINOUT
(PIN TIA/EIA-568B)
TIPS FOR USING STP CABLE
1. STP (shieldin twisted pair) Cable.
2. STP (shieldin ) RJ45 connector with STP cable connection.
SYNC MODE SELECT SWITCH
← Mode 1
Mode 2
1. For “newer” monitors, such as LCD monitors over 17”, it is recommended usin Mode 1 for the best transmission
stability. If the picture is not normal, please switch to Mode 2.
2. For “older” monitors, such as CRT or LCD monitors under 17”, it is recommended usin Mode 2 and adjustin the Sync
Filter Level at the receiver. If the picture is not normal after followin above su estion, please chan e UTP to STP
(shieldin twisted pair) cable.

Sync Filter Level is desi ned for improvin si nal synchronizin stability, not for picture quality or skewin problems when
usin UTP cable.
There is no definitive settin as monitors have different set values. Please try multiple levels of settin to fi ure out the best
stability.
If there is no picture display or picture is not stable after adjustment, please chan e the UTP to STP cable.
CAUTION
1. The wirin must be kept away from electroma netic equipment, i.e. microwave, wireless, hi-volta e cables,
etc.
2. The maximum distances supported by the VGA Extender are dependent on the type of twisted pair cable
and ima e resolution of the PC’s VGA interface. Make sure that the maximum recommended operational
distances have not been exceeded.
3. All wirin is “strai ht-throu h” twisted pair cable, and not to be used for other LAN or telephone equipment.
4. Do not connect the VGA Extender to a telecommunication outlet wired to unrelated equipment.
