Transmitter:
1． Connect VGA signal (to be send) t o transmitter’s AUDIO IN
2． Connect audio signal (to be send) t o transmitter’s AUDIO IN
3． Connect power supply plug to transmitter’s POWER
4． 5 reticle ‘s RJ45 Insert TP-OUT
5． setup all “K” is shut. please make switch is ON (when transfer distance > 200m)
Notice: setup position of switch K must based on transfer distance and image effect.,still don’t satisfy image contrast after contrasting.please setup switch K is “ON”

Receiver
for 2 pcs VGA outptut on receiver so can connect 2 displays at the same time.but the lighteness will reduce when connecting 2 displays.so here you can use bright adjustor to adjust lighteness.and Contrast adjustor to adjust contrast for different transfer distance .
1．connect display input to VIDEO-OUT1 or VIDEO-OUT2
2．connect audio output to AUDIO-OUT.
3．5 reticle ‘s RJ45 Insert TP.

Facture of RJ45 plug::
RJ45 must be parallel, can’t appear crossover in twisted-pair. Seriation as follow:white orange / orange/ white green/ green / white blue / blue/white palm / palm.

Receiver adjustor
Make the image look better via BRIGHT / CONTRAST adjustor
Still don’t satisfy the image’s contrast after you adjusting.please setup all switches K of receiver are “ON”
Lighteness,contrast,and switch K is OK for 300M transfer distance when leaving factory.
