3. e powering on another module pair Note If multiple systems are setup in the same vicinity and pairing is lost between one or more TX RX module pairs power off the modules of the pairs that failed then power on each pair one ata time and allow it to synchronize before powering on another pair D Usage Notices 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 few seconds to insert it again Adjust antenna to decrease interference vertical or horizontal 4 In most situations one pair has a better distance up to 250M line of sight and open sight When two pairs or more are used at the same time It can automatically jump to different channels But the distance 6 between transmitter preferably greater th and transmitter receiver and receiver an 2 meter far E Troubleshooting 1 Monitor RX shows No Video Signal 2 Monitor RX shows No Signal 3 No picture 4 Interference picture 5 PTZ can not be controlled Please check ifcamera power off or broken Please check if TX power off TX RX distance is Check power switches on the remote TV or DVR and Video source Camera Camcorder etc Adjust receiver and transmitter antenna orientation Try to place transmitter and receiver a little mo
4. ocate the TX module close enough to your video source to connect to them Use appropriate fasteners to anchor the TX module to the mounting surface 3 Connect a BNC video power extension cable not provided to Video In and Power drop cables of the TX module then to your video source camera and 12 VDC power adapter provided 4 Connect the RS485 leads of the TX module to the local RS485 PTZ equipment you want to control if needed Step 2 Installation RX module The RX module includes one of BNC video drop cable to connect our video monitor recording equipment TV DVR one pair of RS485 leads and one power drop cable 1 Screw an antenna onto the SMA connector on the back of the RX module 2 Locate the RX module close enough to your video recorder and RS485 controller to connect to them Use appropriate fasteners to anchor the TX module to the mounting surface 3 Connect a BNC video power extension cable not provided to Video Out and Power drop cables of the RX module then to your monitor recording equipment TV DVR and 12 VDC power adapter provided 4 Connect the RS485 leads of the RX module to the local RS485 PTZ controller if needed Step 3 Pairing the TX and RX modules The TX and RX modules of each product are factory configured to synchronize only with each other Effective synchronization is achieved when the video carried through the system can be seen at the video recording or monitoring equipment connected
5. re The transmission path between the pair may be overlapped to the other pair must install higher position or separate these two pairs There would be a high power pair unit near by TX or RX please find it and move Make sure video signal transmission is OK Otherwise refer 1 or 2 Then check the interconnection is OK Especially the RS485 lead polarity is right After then check if the Baud Rate of all the devices in the system is set to 2400bps such as PTZ camera DVR F Specifications TX RX ranas RX Receive Baud Rate 2400 bps Default Value Antenna omni antenna 9dBi or 3dBi option Receiver Sensitivity 85m min Power Consumption 1 9W Weigh System 720 x 480 30 fps NTSC or 768 x 576 25 fps PAL PTZ Control Protocol Pelco D or Pelco P auto detect Baud Rate 2400 bps up to 250M 350M depends on the antennas line of sight and open sight Video Resolution Operational Range e All specification subject to change without notice
6. to the RX module and an RS485 controller at the RX module can control a PTZ device connected to the TX module Synchronization of a single TX RX module pair occurs automatically after the TX and RX modules are powered on If synchronization is lost it can be re established by powering off then powering on one of both of the modules After powering off either module wait 10 seconds before powering it on again To automatically synchronize a TX and RX module pair 1 Plug the 12VDC power adapter for the TX module into a wall outlet 2 Plug the 12VDC power adapter for the RX module into a wall outlet 3 Verify that you can see video from your video source equipment at your video recorder 4 Verify that you can control the remote RS485 PTZ device using your RS485 controller Note 1 PTZ protocol of this system is Pelco P orPelco D only It can be auto detected and itmust be the same between PTZ camera and PTZ keyboard or DVR 2 The default baud rate of TX and RX module is 2400bps The PTZ camera PTZ keyboard or DVR must be setup with same baud rate 3 RS485 leads must be connected correctly The yellow wire is positive or A and the white wire is negative or B Multiple TX RX systems When setting up multiple systems in the same vicinity observe the following guidelines Place RX modules at least 1 ft apart Power on each TX and RX module pair one at a time and allow the pair to synchronize as described above befor
