Make sure power plugs are pushed all the way in

Check power switches on the remote TV or DVR and Video

source(Camera, Camcorder, etc.)

Check if the POWER LED of the transmitter and receiver is lighting or

not? Their LINK LED should be lit.

If The LINK LED is lit, you must re-pair their codes following the D.

instruction of the manual

Interference: picture

or audio

Adjust receiver and transmitter antenna orientation

Try to place transmitter and receiver a little more close together

The transmission path between the pair may be overlapped by another pair, try to install into a higher

position or separate these two pairs

Trouble shoot by turning off any high power wireless units that are

near by TX or RX, please find it and move or un plug from power.

When RX output to TV monitor or DVR, the screen will show PTZ camera information as

below:

this information will disappear shortly.

1. Be sure the transmitter and the receiver were connected to the

equipment correctly(e.g. Connect the transmitter to the camera,

and the receiver to the TV

or DVR ).

2. When DC plug is pulled out from transmitter or receiver, it needs to wait for a fewseconds to insert it again.

3. Adjust antenna to decrease interference. (vertical or horizontal)

4. In most situations, a pair has a distance up to 150M(line of sight and in a wide open space) .When two

pairs or more are used at the same time, it can automatically jump to different channels. Keepthe distance between transmitter and transmitter (receiver and receiver), preferably it should begreater than 3 meter apart.

Problems Possible Solution

Monitor(RX) shows

“No Video Signal ”

Camera power off or stolen, camera cable disconnected or

damaged, please check and fix accordinglyMonitor(RX) shows

“No Signal”

TX power off; TX/RX distance is too long, if so that transmission signal

is weak, please check and make it right

RS485 of the TX module connects to the PTZ Cameras RS485 port , and the RX RS485

port connect out to RS 485 port of PTZ keyboard or DVR, so that keyboard or DVR can control its Pan/Tilt/Zoom actions via wireless and a long distance; please note the PTZ protocol used for this system is only Pelco P or Pelco D, they are auto detect , and must be same in the PTZ camera and PTZ keyboard or DVR, baud rate are 9600bps/4800bps/2400 bps /1200bps, you have to

setup the PTZ camera /this system(TX/

installed outdoor when power source is limited.

Thank you for purchasing this indoor/outdoor 2.4GHz Digital AV Sender. This transmission system is a digital wireless audio/video

sender

that uses 2.4GHz Frequency

Hopping technology (not fixed frequency)

and 16QAM/QPSK/BPSK

modulation, and random ID codes to protect personal privacy , for video and RS485 communication.

There are over a billion hopping sequences that help to minimize interference and deliver consistently an excellent video and audio signal up to 150M meters away by 100mW

transmission power and 3dBi antenna , you may use a high gain antenna to increase the distance.Using this 2.4GHz Digital Wireless A/V Sender, you can enjoy greater convenience and security in many ways:

Safety & Security Application:

Connect a PTZ camera to wireless security system , control its Pan/Tilt/Zoom actions via RS485 port from the receiver(RX), through PTZ keyboard or DVR with PTZ function

Please note: Pairing Light (red)

Pressing the pairing buttons for the transmitter and receiver is not necessary to do at the same time, and they do not need to be placed near or side by side during pairing status, with in or around 3 meters distance is OK

. Under

the transmission, you can see the signal

strength on the monitor with RX connected to it as below, and will disappear after 5 seconds; press RX pairing button to make signal strength show again
