In the operation of the IC card canteen rice sales system, it is often necessary to send all kinds of data to the window of the rice vending machine, including system parameters, blacklists, and whitelists. The data in the canteen punch card machine must also be uploaded to the database of the food sales system every day, and sometimes there will be a situation where the canteen food sales system cannot provide data to the window of the food vending machine.
We know that the computer in the rice sales system and the IC card punch card machine are linked through the network cable and the communicator, if the data cannot be uploaded, that is, there is a problem with the communication of the system, and any problem in the system will lead to this situation.
We can take a look at the composition of this link: computer (system software) - communicator - communication line - rice vending machine, we can exclude them one by one.
First, check if your computer is set up correctly. We can open the rice sales management software to check whether the parameters of the rice sales system are set normally, including the communication port, the settings of the rice vending machine, etc. If the port is set incorrectly, it will definitely not be able to communicate.
In addition, it depends on whether the rice vending machine is set up normally in the system, if the system consists of 10 rice vending machines, but the machine number set by your software is 1-9, then the 10th rice vending machine must not be able to communicate.
Secondly, we check if the communicator is normal. First of all, check whether the communication cable is wired correctly and whether it is reversed? If the wiring is correct, check whether the communicator is plugged in on the COM port of the computer.
In addition, if there is a spare communicator, you can replace the spare communicator and check whether the system communicates normally.
Third, communication lines. Since the communication line is generally relatively long, and many times it has to penetrate walls and holes, this part is also prone to problems. You can follow the wiring of the communication line to check whether there are any breaks, loose tape, etc.
Finally, if there is no problem with the above, we are basically sure that there is a problem with the communication module inside the canteen rice vending machine, you can open the rice vending machine, check whether the communication module is loose, breakdown, short circuit, if you find that there is an abnormality, you can generally replace the communication module. Of course, if the machine number of the rice vending machine is set incorrectly, there will also be a situation where a rice vending machine cannot be detected, so it is necessary to set the machine number of the rice vending machine correctly. Turn off the power of the rice vending machine, press and hold the three keys of "0", "9" and "Clear" at the same time, then turn on the power, then enter the correct machine number, and then press the "OK" button.

Shenzhen Yihechuang Electronics, canteen credit card machine manufacturers remind you, is it not the best data or? If so, is there any hint about the data? You can check whether the string slogan is not selected correctly, whether the communication method is right, and whether the phone number is right?

Check whether the network is smooth first, and then check the cash register software settings. I do chain cash register software, and there is a software problem, the data is too large, and there is a problem with the transmission.
-
The data of the Meimai cash register cannot be transmitted, which may be due to the poor network or the setting is not good.

Have you set up your router?
There is a small twist on the back to hold down 5 magic factory reset reset to try reinstallation.
First of all, if there is a wireless router, then first turn on the power supply, and then plug in the network cable, plug in the WAN port (usually the blue port), and then connect with the computer network cable to plug in any LAN port, after doing these jobs, then you will see that there is an address and account password behind the router, after connecting, enter the address you see in the router in the browser, generally of course, if your home is using ** online network, then you have to prepare an additional modem, commonly known as "cat").
02 Then enter, enter the corresponding account and password, generally the newly bought are admin
03 After entering the operation interface, you will see a setup wizard on the left, Attack on the entry (generally pops up automatically).
04Enter the setup wizard interface.
05 Click Next, enter the Internet access method settings, we can see that there are three Internet access options, if your home is dial-up, then use PPPOE. Dynamic IP can be used by plugging the computer directly into the network, and there is a DHCP server on the upper layer. The static IP is generally a private line or something, or it may be a cell bandwidth, etc., and the upper layer does not have a DHCP server, or wants to fix the IP.
I chose PPPoE because I dialed.
06 If you choose PPPOE dial-up Internet access, you need to fill in the Internet account and password, which should be understood by everyone, and there will be an account number to open broadband, and it is OK to fill it in.
07 Then the next step is to enter the wireless settings, we can see the channel, mode, security options, SSID, etc., generally SSID is a name, you can fill in at will, and then the mode mostly uses 11BGNFor wireless security options, we need to choose WPA-PSK WPA2-PSK, which is so safe that it will not be hacked and rubbed by the network.
08The next step is to set it up successfully.
09Click Done, the router will automatically restart, at this time you should wait patiently. The interface that appears after success.

Is the WAN port set correctly? Is the network cable plugged in, check the network cable!

It is normal for serial cards to have this problem. You can rule out question 1 in this way, whether the control card model, com port and baud rate are selected correctly.
2. There is no problem, check whether the communication lines are parallel or crossed, and whether there is any broken circuit.
4. There is no problem with the computer and communication cable, see if the jumper caps of 232 and 485 on some cards are set correctly. 232 should be selected, and some cards have address switches to see if these switches are messed up. If you have other cards in hand, it's best to try changing them.
5. Such a step-by-step problem can be solved.
Constant dancing card, creating the era of screen movement. This card does not use serial communication, and it is the best choice for offline control.
-
You need to test whether the serial port is faulty and the data cannot be transmitted.
-
Please check whether your wiring method is correct, whether the baud rate is consistent, and whether your computer's serial port is good.
-
What model is your control card? It is possible that the drive is not installed properly.

There is also a bit of a problem on the first floor, when the computer receives first, the instrument is sending, but when uploading, the instrument receives first, and the computer then sends, that is, the receiving end starts first and then the sender sends, otherwise there will be data loss.
There is also a problem with the software, the upload data must use the software that comes with the machine, and other software has compatibility problems.
-
1. Are the settings of communication parameters the same?
2. Is it the operation procedure that the computer receives first and then sends by the total station?
3. There is a problem with the data cable or interface.
-
If the communication parameters are set, it may be a problem with the data cable, and the data cable may be one-way.
