EAS RF 8.2MHz X7 DSP Super Strong Motherboard Brief

Dear friends,

EAS RF 8.2MHz X7 DSP Super Strong Motherboard is a popular accessory in EAS system.It is made of PCB material.The color is dark blue.It is divided into Tx,Rx (transmit and receive). The X7 motherboard contains all the advantages of the X3 and X5 motherboards, and this motherboard is equipped with a DSP chip (digital signal processor). It can effectively process the signal quickly, and the alarm speed is faster and more sensitive. Stronger anti-interference, more stable work.

When the power supply is connected, the power indicator signal light on Tx and Rx will light up, among which, Rx has four status lights, if there are 1-4 lights flashing green, it means that it works normally, if there is 1 signal light red, it means that there is something interference (may be metal objects), if it is 4 lights all bright red, it means that the interference is very serious. At this point, you need to move nearby objects containing metal up to 30 centimeters until it stops flashing red. So, what if the green light doesn't work? At this time, you need to adjust the signal sensitivity on the Rx, adjust the button in "VR4", you need to use a screwdriver to rotate, clockwise is to increase the sensitivity, counterclockwise is to reduce the sensitivity, until it can work normally. Of course, the alarm sound can also be adjusted on the Rx, which is turned up clockwise and turned down counterclockwise.

The prices shown in this link are accurate, there are rich payment methods to choose. if you have any questions, please feel free to contact us! Our ideal is to help all the good people who want to open a good retail store to do a good job of anti-theft and smart management. We hope our expertise can help you! MAKE RETAIL SAFER!

With best wishes!

Tx
Be sure to connect the input voltage correctly as shown in the figure below, and do not connect the positive and negative poles reversely. Wrong connection to the ground port will cause the electronic components of the circuit board to burn out.
Note: Except for the power supply and synchronization interface that need to be connected, other components have been adjusted to the best condition at the factory.

Rx
Note: VR4 is sensitivity adjustment (increase sensitivity clockwise, decrease sensitivity counterclockwise)

Tx-Rx
Note: 10mm expansion screw is standard, please use 12mm drill bit to fix.

RF-X3
Advantages: sensitive induction, harsh alarm sound, alarm response speed, all-solid-state capacitor motherboard, stable work guarantee, can manually adjust the increase or decrease the sensitivity function, multiple protection: positive and negative pole connection anti-motherboard burning, fuse disintegrating protection, etc.

RF-X5
Advantages: Contains all the advantages of X3, strengthens the anti-interference ability of multiple environments such as the same frequency environment, electromagnetic environment, and other interference sources, and operates more stably in more different environments.

RF-X7
Advantages: Includes all the advantages of the X3 and X5 motherboards, this motherboard is equipped with a DPS chip, the digital signal processor. It can effectively and quickly process the signal alarm faster and more sensitive. Stronger anti-interference, more stable work.
