If it is a walkie-talkie without a keyboard, you can measure the frequency with a frequency meter (a frequency meter is generally above 90 yuan), or find the corresponding frequency writing software of the walkie-talkie and then export the frequency on the computer.
Step 1: Install the frequency writing software.
1, download the frequency writing software. Frequency writing software is generally downloaded from walkie-talkie official website. It should be noted that walkie-talkie manufacturers will produce many walkie-talkies with different specifications, so when downloading the frequency writing software, first look at the brand and model of the walkie-talkie you bought, and then go to the official or third-party website to download the required frequency writing software according to the model.
2. After getting the frequency writing software and installing it, you can proceed to the second step.
Step 2, connect the equipment.
1, the classification of interphones. There are two kinds of walkie-talkies, one is digital walkie-talkie, there are many digital buttons on the panel of digital walkie-talkie, and the other is analog walkie-talkie.
2. Know the writing frequency jack. The walkie-talkies that children often see in real life are analog walkie-talkies. Generally, there are earphone jacks and writing frequency jacks, which are generally K-type, M-type and Y-type.
3. Connect the write frequency line. Insert the USB port into the computer, and then insert the writing frequency cable into the writing frequency jack of the interphone (that is, the K head), which is the same as the plug of the interphone earphone.
4. The goal of this case is to adjust the walkie-talkie of ZN520-2C to the same frequency as that of ZN520-2A, so as to realize the conversation between the two parties, so two kinds of frequency writing software should be downloaded and installed before this. First, we open the frequency writing software of ZN520-2C walkie-talkie. The interface of the frequency writing software is as follows.
3. Reading frequency. First, turn on the power switch of ZZ520-2C walkie-talkie, then connect ZZ520-2C walkie-talkie with the computer through the frequency writing cable, click Edit of frequency writing software → Frequency Reading in turn to open the "Frequency Reading" dialog box, and click OK to read the data of each channel of ZZ520-2C walkie-talkie, as shown in the following figure.
Step three, frequency modulation.
1, reading frequency. Unplug the ZN520-2C walkie-talkie and connect the ZN520-2A walkie-talkie to be FM. First, perform a frequency reading operation. If the frequency can be read normally, it means that the communication between the walkie-talkie and the computer is normal, otherwise it is necessary to check where the problem lies. Open the frequency writing software of Sino-Z520-2A interphone, click Programming → Read Data from Intercom in turn to open the "Read Data from Intercom" dialog box, and click OK to read the data of each channel of Sino-Z520-2A interphone. We see that the parameters of each channel of the two walkie-talkies are inconsistent, as shown in the figure below.
2. Manually enter the parameters of each channel. Open the channel information picture of Sino-ZN520-2C walkie-talkie that we just saved, and refer to this channel data map. In the frequency writing software of Sino-ZN520-2A walkie-talkie, manually input all kinds of data in turn according to the channel. The channel data of SINO ZN520-2C frequency writing software shall be completely consistent with the channel data of SINO ZN520-2A interphone.
3. Write frequency. After the data input of each channel is completed, it should be carefully checked again before the frequency writing operation can be carried out. After confirmation, click "Programming" → "Write data to walkie-talkie (W)" of the frequency writing software of ZN520-2A walkie-talkie in turn to open the "Write data to walkie-talkie" dialog box.
Click the "OK" command button to start writing the data of each channel of Sino-Norwegian ZN520-2A interphone. When the data is completed, the Write Complete dialog box will pop up. Click the OK command button to close the current dialog box.
At this point, the FM of ZZ520-2C walkie-talkie and ZZ520-2A walkie-talkie has been completed, and ZZ520-2C walkie-talkie and ZZN520-2A walkie-talkie have been tuned to the same channel, such as 16 channel. Make a phone call once, haha, the two machines can communicate!
