Cash register equipment series Mercury 185F Incotex is very popular among small businesses due to its reliability and functionality. However, a high-quality network connection is key to ensuring stable data transfer to the OFD and EGAIS. Setting up Wi-Fi on this device often raises questions among users, especially if they previously used models with a cable connection or GPRS modems.
Properly configuring the wireless module allows the cash register to operate independently from a desktop computer and transmit receipts even if there's no wired internet connection at the point of sale. In this article, we'll cover the connection process in detail. Mercury 185F to the wireless network, paying special attention to the router settings and the parameters of the terminal itself.
It is worth noting that the success of the operation depends not only on the correctness of the entered data, but also on the compatibility of security standards. Wireless connection requires careful preparation to avoid connection interruptions when the check is being processed, which is critical for compliance with Federal Law No. 54.
Equipment preparation and compatibility testing
Before you begin setting up your cash register menu, you need to ensure that your infrastructure is ready. Mercury 185F Equipped with a built-in Wi-Fi module that supports certain encryption standards. If your router is configured to use outdated or too-new protocols, the cash register may simply not see the network.
First, check whether your router is broadcasting a 2.4 GHz signal. Many modern dual-band routers hide the 2.4 GHz network by default or combine it with the 5 GHz network under a single name, which can cause conflicts when connecting to a cash register. Frequency range is a critical parameter for stable operation of the fiscal registrar.
⚠️ Please note: Cash registers often do not support the WPA3 standard. If your router is configured to only support this type of security, the cash register will not be able to log in to the network.
It's also important to know your wireless network password in advance. Unlike smartphones, entering complex characters on a cash register keypad can be difficult, so make sure you know the exact password. access key and keyboard layout (letter case).
- 📶 Make sure your router is turned on and transmitting a signal within range of the cash register.
- 🔐 Check the encryption type in your router settings (WPA2-PSK is recommended).
- 📟 Charge the cash register battery or connect it to a power source to prevent it from turning off during the process.
If you are using a corporate network with authorization via a web interface (captive portal), you may not be able to connect the cash register directly without the help of a system administrator. Mercury 185F It is intended primarily for connecting to open or password-protected home networks.
Navigating the cash register menu
Interface Mercury 185F The setup mode is based on sequential selection logic. To enter the setup mode, you must have administrator or cashier rights, depending on the firmware version. The standard procedure begins with the main screen, which displays the date, time, and status of the fiscal storage device.
To access network settings, press the menu button (usually labeled "M" or accessed via the key combination described in the manual). Then select Settings and go to the section Utility parameters or Network settingsThis is where all communication interfaces are controlled.
Inside the menu, you will see a list of available interfaces: Ethernet, USB, and Wi-Fi. Select the item Wi-Fi and press the Enter key. If the module is working properly, the system will prompt you to enable it or scan for available networks. Activating the module It may take several seconds, as indicated by the flashing indicator on the body.
What should I do if the Wi-Fi option is not in the menu?
If the Wi-Fi option is missing from the menu, you may have a model of the cash register without a wireless module or a firmware update is required. Check the device's registration document or contact the service center.
If you make a mistake, use the red undo button to go back a step. Keyboard The cash register is also used to enter characters, which requires care when entering the password.
Search for a network and enter connection parameters
Once search mode is activated, the cash register will begin scanning the air. A list of available SSIDs (network names) will appear on the screen. Find the name of your access point in the list. If the network is hidden, select Enter manually and type the network name using the alphanumeric keyboard.
When you select your network, the device will ask for an encryption method. In 99% of cases for home and office networks, this is WPA/WPA2Select this option and proceed to entering your password. The system will display your input as asterisks or periods for security, so enter the characters slowly and carefully.
☑️ Check before connection
Pay special attention to the letter case. Password MyPassword And mypassword - these are two different keys. Mercury 185F The password is sensitive to these details, and even a single character error will result in connection failure. After entering the password, click the confirm button.
The cash register will attempt to obtain an IP address from the router automatically via DHCP. This process takes 5 to 15 seconds. If a success message appears on the screen and the IP address is displayed (e.g., 192.168.1.45), a physical connection has been established.
IP Address and DNS Configuration
In most cases, IP address and DNS server settings are configured automatically. However, in complex corporate networks or when using static IP addresses, manual configuration may be required. Go to the section IP settings inside the Wi-Fi menu.
Here you can switch the mode from DHCP on Static (Static). In this case, you'll need to manually enter the IP address, subnet mask, gateway, and DNS servers. This information should be provided by your internet service provider or system administrator.
| Parameter | Description | Example of meaning |
|---|---|---|
| IP Address | Unique address of the cash register on the network | 192.168.1.150 |
| Netmask | Subnet mask | 255.255.255.0 |
| Gateway | Gateway (router) address | 192.168.1.1 |
| DNS Primary | Primary DNS server | 8.8.8.8 |
An incorrectly specified gateway is the most common reason why the cash register "sees" the router but has no internet access. Make sure the gateway address matches your router's address. Default Gateway provides access beyond the local network.
Also, check your DNS settings. If automatic DNS retrieval isn't working, try specifying public servers, such as Google (8.8.8.8) or Yandex (77.88.8.8). This often resolves issues with resolving domain names on the OFD servers.
Checking the connection and diagnostics
After successfully obtaining an IP address, you need to ensure that the cash register actually has access to the global network. The Wi-Fi settings menu often includes an option Connection test or PingRun it to check the connection with the outside world.
If the test is successful, the checkout will display the response time (ms). If you see a timeout error or no connection, the problem may be due to blockages on the router side. Check if your Mercury 185F in the Blacklist or whether the MAC address filtering mode is enabled.
For a more in-depth diagnosis, you can check the connection status in the interface status report. It will display the signal strength (RSSI). If the signal level is below -80 dBm, we recommend moving the cash register closer to the router or using a Wi-Fi repeater.
⚠️ Caution: Wi-Fi signal strength may fluctuate due to interference from microwave ovens or other electronic devices. Place the cash register away from sources of strong electromagnetic fields.
Also, make sure the date and time at the cash register are set correctly. An incorrect system time can cause errors when establishing a secure connection (SSL/TLS) with the fiscal servers, even if Wi-Fi is connected.
Setting up data transfer to the OFD and EGAIS
Connecting to Wi-Fi is only half the battle. Now you need to configure the software to transmit fiscal data. Go to the section OFD settings In the main menu of the checkout, select the connection type: Ethernet or Wi-Fi (depending on the firmware, the item may be called “Network”).
Enter your Fiscal Data Operator's server address and port. Your Fiscal Data Operator provides this information when you sign the contract. The address typically looks like a domain name (e.g., ofd.ru) or IP address. The port is usually standard - 20261, but it’s better to double-check the contract.
Similar steps are required to configure the EGAIS if your business involves handling alcoholic beverages. Here, you also select the network interface and enter the FSRA server addresses. Communication channel must be stable, since interruptions when sending data to EGAIS can lead to blocking of activity.
After entering all the parameters, perform a test receipt send. If the receipt is sent and a success message appears on the screen, and a receipt with a fiscalization flag prints, then the settings are correct. Mercury 185F completed successfully.
Solving common problems
Even if you follow all the instructions, you may encounter difficulties. One common issue is that the cash register sees the network, but constantly displays a "Connection Error." This may be due to the router's DHCP table being full. Try rebooting the router to reset the leased addresses.
Another scenario: the cash register connects but doesn't send receipts. Check that the security certificate on the cash register or in the fiscal storage device hasn't expired. Also, make sure your router isn't limiting the speed for new devices or blocking ports.
⚠️ Note: Interfaces and menu item names may vary slightly depending on your cash register's firmware version. Always consult the manufacturer's current documentation for your specific model.
If all else fails, reset your network settings to factory defaults and try setting up the connection again. As a last resort, contact the Technical Service Center (TSC) to have the Wi-Fi module hardware diagnosed.
Regularly check for cash register firmware updates on the manufacturer's official website. New software versions often contain compatibility fixes for new router models and improve wireless connection stability.
Why doesn't the Mercury 185F cash register detect my Wi-Fi network?
Most likely, your network operates in the 5 GHz band, while the cash register only supports 2.4 GHz. Also, check that the network name (SSID) isn't hidden in your router settings and that MAC filtering isn't in use.
Is it possible to connect a cash register to Wi-Fi with SMS authentication?
No, Mercury 185F Doesn't support Captive Portal login pages that require a phone number or social media login. The device only works with a WPA2 password.
How can I find the MAC address of the cash register's Wi-Fi module?
The MAC address is usually found on a sticker under the battery or on the box. It can also be found in the cash register menu: Settings -> About the device -> Network interfaces.
What should I do if the cash register connects but displays "No connection with OFD"?
Check the address and port of your data operator (OFD). Make sure no ports are blocked on your router. Try changing your DNS to 8.8.8.8. If the problem persists, contact your data operator's technical support.
