Model Mercury 130F Incotex is one of the most popular solutions on the market, but initial setup of the wireless module often presents difficulties for users. Proper configuration network parameters avoids downtime and ensures timely receipts.
The setup process involves more than just selecting a network from a list, but also correctly entering passwords and sometimes manually assigning static IP addresses. Errors at this stage can result in the device operating in standalone mode, accumulating tax documents, which creates risks during audits. In this article, we'll cover all the details of the connection. Mercury 130F to the wireless network, including work via a PC and directly from the cash register keyboard.
It is worth considering that the menu interface may differ slightly depending on the version installed. firmwareBefore you begin, make sure you know the exact password for your Wi-Fi network and, if necessary, the MAC address of the device being filtered on the router. Below are detailed instructions to help you establish an internet connection.
Preparing to set up a wireless connection
Before entering network parameters, ensure the equipment is ready. First, check that the cash register is powered on and in "Cash Register" mode (receipt mode), not in standby mode or turned off. Configuration often requires access to the password-protected administrative menu.
Standard password for entering the cash register setup mode Incotex is a combination 30If the password was changed by the previous owner or administrator, you will need to find out the current data. It is also important that the Wi-Fi module is physically installed in the device, as some basic configurations may only come with an Ethernet port.
- 📶 Make sure your router is transmitting a 2.4 GHz signal, as POS modules often don't support the 5 GHz standard.
- 🔋 Check the battery charge or the power adapter connection to prevent the device from turning off while saving settings.
- 📝 Write down the MAC address of the cash register, which is located on the sticker on the back of the device or on the label inside the battery compartment.
⚠️ Attention: If you are using a corporate network with authorization via a web portal (Captive Portal), direct connection of the cash register may not be possible without setting up MAC address forwarding on the system administrator's side.
To perform fine tuning, it is recommended to use a PC with the cash register driver and utility installed. Test KKM or Cash desk 130This will allow you to not only enter Wi-Fi parameters but also immediately run a test check to ensure the operation was successful. However, basic operations can also be performed using the built-in keyboard.
Setting up Wi-Fi via the cash register menu
The fastest way to connect Mercury 130F To connect to the internet, use the device's built-in menu. This method is convenient because it doesn't require a computer, although it's less informative in the event of errors. To enter the settings menu, press Mode, enter the password 30 and press BB.
In the menu that opens, navigate using the arrow keys. Find "Settings" or "Network," then select "Wi-Fi." Once the module is enabled, the cash register will begin searching for available networks. If your network is hidden, you'll need to manually enter the SSID.
When entering your password, be extremely careful: it's case-sensitive, and characters may not be displayed visually (they'll be shown as asterisks). Use the navigation keys to switch between letters, numbers, and special characters. After entering all the information, select "Save" or "Connect."
- 🔍 In the list of networks, find the name of your router (SSID) and press the enter button.
- ⌨️ Enter your Wi-Fi password, using the uppercase key to switch between uppercase and lowercase.
L(or similar functionality). - ✅ Confirm saving the settings and wait for the signal strength icon to appear in the upper right corner of the screen.
If the network icon appears but is red or flashing, this means you're connected to the router but can't access the internet. In this case, check your router settings or DNS settings. If the icon isn't there, repeat the password entry process, ensuring the keyboard layout is correct.
Network configuration via a utility on a PC
A more reliable and professional way to set this up is to use a computer. To do this, you will need to install drivers For Mercury 130F and a specialized program (for example, "Kassa 130" or "Test KKM"). Connect the cash register to the computer via a USB cable before turning on the power.
After launching the program and successfully connecting to the device, go to "Settings" -> "Network" -> "Wi-Fi." Here you'll see an expanded list of options, including the ability to configure a static IP address, which is often required in office networks with strict security policies.
Example of a sequence of actions in software:1. Open the "Hardware Settings" tab
2. Select "Communication Settings"
3. Go to "Wireless Network (WLAN)"
4. Enter the SSID and encryption key
Pay special attention to the "Security Type" field. Most home and office networks use WPA2-PSKSelecting the wrong encryption type will result in a connection error, even if the password is entered correctly. After filling in all fields, click the "Save to KKM" button.
☑️ Check network settings
The advantage of setting up via a PC is the ability to immediately run diagnostics. The program can display the signal strength (RSSI) and connection quality, which helps determine whether the router needs to be moved closer to the cash register or whether a USB Wi-Fi antenna with an external cable should be used.
Solving common connection errors
Even if all instructions are followed, users may encounter difficulties. One of the most common issues is that the cash register detects the network but fails to connect. This is often due to the router broadcasting the network in mixed mode, which is not supported by the old Wi-Fi module inside the cash register.
Try changing the router settings to the wireless only mode. 802.11b/g/n and a channel width of 20 MHz. A wide channel (40 MHz) in the 2.4 GHz band can create interference and instability for cash register equipment.
| Error | Possible cause | Solution method |
|---|---|---|
| Incorrect password | Error entering or changing the password on the router | Recheck your password and reset your router's network settings. |
| No connection to the server | Invalid date/time or DNS | Synchronize the time, enter DNS 8.8.8.8 |
| Network not found | Long range or 5 GHz frequency | Move the router closer and switch the router to 2.4 GHz. |
| Access denied | MAC address filtering | Add the cash register's MAC address to the router's whitelist |
⚠️ Please note: Cash registers are sensitive to the accuracy of the system time. If the date on the register is incorrect, the connection to the fiscal data operator (FDO) will be lost, even if the Wi-Fi is working properly. Always check the time before troubleshooting your network.
It's also worth mentioning the issue with characters in the network name (SSID). If your Wi-Fi network name contains Cyrillic or special characters, the cash register may display them incorrectly or not recognize the network at all. It's recommended to rename the network to a Latin-based name without spaces or complex characters.
Working with a static IP address
In some cases, especially when integrating a cash register into a local enterprise network with multiple access points, it is necessary to register static IP addressThis allows the cash register to always have the same network address, simplifying remote management and monitoring.
To switch to a static IP, access the network settings on your PC. Disable the "Obtain an IP address automatically" (DHCP) option. You will need to manually enter the IP address, subnet mask, gateway, and DNS servers. The address must be in the same subnet as your router, but not the same as the addresses of other devices.
An incorrectly specified gateway is the most common error during manual setup. The gateway is your router's address. If it's incorrect, the cash register will be connected to Wi-Fi but won't have access to the global network.
After changing the IP address type, be sure to reboot the cash register. Only after a full power-up cycle and the operating system has loaded. Mercury will apply the new network settings.
Connection quality check and testing
Once all settings have been entered, you need to ensure a stable connection. In the cash register menu or through the PC program, you can find the "Connection Test" or "Diagnostics" option. The device will send a test data packet to the server and receive a response.
It's considered good practice to issue a "Correction Receipt" or a test receipt with a return to verify the complete fiscal data transfer cycle. Make sure the receipt has been sent to the fiscal data operator, as indicated by a corresponding note on the receipt or in the document log.
- 📡 Check the signal level: it should be at least 2-3 divisions for stable operation.
- 🧾 Print a payment status report to ensure there are no outstanding documents.
- 🔄 Restart your router and check if the connection at the checkout is restored automatically.
What to do if the Wi-Fi signal is very weak?
If your cash register is located far from your router, you can purchase an external USB Wi-Fi adapter with an antenna. Make sure it's compatible with your cash register's chipset (usually an RTL8188 or similar driver is required).
Regular network monitoring will help prevent situations where the cash register accumulates thousands of receipts in the fiscal data file archive. If you notice a drop in data transfer speed, try changing the router channel to one with less congestion.
Frequently Asked Questions (FAQ)
Is it possible to connect the Mercury 130F to a hidden Wi-Fi network?
Yes, this is possible. In the Wi-Fi settings menu, select "Other network" or "Enter manually." You will need to know the exact network name (SSID), case-sensitive, and encryption type. Hidden networks may take longer to connect when the register is turned on.
The cash register says "No connection to the server" even though Wi-Fi is connected. What's wrong?
The problem is most likely not with Wi-Fi, but with the time or DNS settings. Check that the date and time at the checkout match the actual time. Also, try setting a static DNS (8.8.8.8) in your network settings.
Does Mercury 130F support 5GHz?
Most standard Wi-Fi modules in this model only operate in the 2.4 GHz band. If your router only broadcasts a 5 GHz signal, the cash register won't detect it. You'll need to enable 2.4 GHz support in your router's settings.
