1. ACTIVE LONG RANGE VGA EXTENTION KIT ITEM NO TTA111VGA The Active Long Rang Kit allows VGA video signals to be transmitted up to 300 meters via 4 paris CAT5 unshielded twisted pairs 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 Active type including transmitter and receiver Built in contrast brightness adjustment at Receiver Supports up to 1600x1200 85Hz Built in ESD and power protection LED indication for power and signal Use 4 pairs UTP CAT5 cable instead of VGA cable for long rang transmission Long range transmission up to 300 meters Max Option model VEO2DALS VGA amp Stereo Digital Audio CAT5 Receiver Built in Skew Corrector Identical to above TTA1L11VGAR CAT5 receiver Built in RGB skew adjustment for the optimum video performance under long cable run It could be daisy chained for another VEO2DALS to extended working range over 300 meters and multiple displays Panel View TTA111VGAT __ i VGA Display Equipment LED Indication Blue Power on off RJ 45 Link Cable Connector Green Sig2.

3. nal on off Installation Tips Skew Picture Due to the inside of CAT5 cable that the pairs of wires are twisted at different rates and the different quality on cable itself and installation that will cause different signal arrival time at each pair If there are big different at arrival time that will cause RGB skew status This is seen on the monitor as separation or lack of convergence in colors Normally it happens on long CAT 5 cable runs RGB Skew A 1 Recommend to use following cabling way to reduce skew status to add special made skew immunized adaptor 2 pieces included at the package Total distance 1 2 Distance 1 2 Distance A E i Short cable to the receiver Receiver Transmitter Skew immunized Skew immunized adaptor adaptor CAUTION to avoid display equipment damaged be sure to make correct cable connection and power for both TTA111VGAT TTA111VGAR before connecting TTA111VGAT TTA1L11VGAR 2 Recommend to change TTA111VGAR CAT5 receiver to VEO2DALS which built in RGB skew adjustment for the optimum video performance under long cable run It also could be daisy chained for another VEO2DALS to extended working range over 300 meters and multiple displays Built in After use Skew adjustment Before use VEO2DALS Specification ITEM NO TTA111VGAR Support Resolution Up to 1600 x 1200 85 Hz Transmission Distance Up to 1000 ft 300 m Video Amplifier
