A modern retail outlet is unthinkable without reliable equipment, and online cash registers of the series Mercury from the company Incotex occupy a leading position in the market. Model 115F It is particularly popular due to its mobility and wireless internet connectivity, which is critical for compliance with Federal Law No. 54. However, initial setup of the wireless module often raises questions for users unfamiliar with the technical intricacies of cash register operation.
The process of activating a WiFi connection is not as simple as connecting a smartphone and requires the use of specialized software. Driver The device acts as an intermediary between the computer and the cash register, allowing for the transfer of complex network settings. Without prior preparation and certain utilities on the PC, this operation will not be possible, even if the router itself is functioning properly.
In this article, we'll detail the entire process required to successfully integrate a cash register into your local network. You'll learn which firmware versions support wireless data transfer, how to properly install drivers, and what nuances may arise during the configuration process.
Preparing the equipment and checking the firmware version
Before you begin tinkering with the settings, you need to make sure your device is technically ready. Not all versions firmware Mercury 115F Have the WiFi module activated by default. It's often the case that the hardware is present, but the software is blocked or requires an update. Checking the software version is the first and most important step; ignoring it can lead to wasted time.
To check the current version, you need to generate a report on the device itself. Click the "Mode" button, select "Reports," and find the line containing the firmware version information. If the version number is too old, you may need to contact a service center or use a USB cable to perform the initial update via a PC.
⚠️ Note: If your model's specifications indicate the absence of a WiFi module, software activation is not possible. Please check the technical documentation for your specific model to ensure the presence of an antenna connector or integrated module. 115F.
Also, make sure you have a Mini-USB (or Micro-USB, depending on the year) USB cable handy to connect the cash register to your computer. Wireless setup from scratch without a wired connection is usually impossible, as the SSID and network password need to be transferred from somewhere to the cash register's memory.
Installing drivers and configuration utilities
The Windows operating system does not always automatically recognize the cash register as a network device. For proper operation, you will need to install drivers From the manufacturer's official website or from the included disc. Without the installed driver, the computer will see the device as an unknown device, and communication with it will be impossible.
In addition to the basic drivers, you will need special utility to configure network settings. This is usually called "WiFi Setup" or is included with the extended KKM driver package. This is the interface you'll use to enter your access point details.
The installation process is standard: run the installer, follow the wizard's instructions, and wait for it to complete. Afterward, the new hardware should appear in Device Manager, and a shortcut for the configuration utility should appear in the list of programs.
☑️ Check before setup
Step-by-step instructions for connecting to a WiFi network
After the preparatory steps, you can proceed to the actual setup. Connect the cash register to your computer via USB cable and turn it on. Make sure the indicators on the register are ready to use. Open the previously installed WiFi setup utility.
In the program window, you'll see a list of available wireless networks within range. Find your router's name in the list (SSID). If the network is hidden, you'll need to enter its name manually. Select the desired network and click "Connect" or "Configure."
The system will prompt you for a password. Enter the security key for your WiFi network. Please pay attention to the capitalization and keyboard layout, as even a single character error will result in access being denied. After entering the information, click "Save" or "Save to Cash Register."
The utility will send a command to the cash register, and the device will attempt to establish a connection. A successful connection is usually confirmed by a status change in the program and the appearance of a corresponding antenna icon on the cash register screen.
Configuring TCP/IP parameters and static address
For stable operation in a local network of a store or office, it is often necessary not only to connect, but also to have the correct IP configurationBy default, the cash register can request an address automatically via DHCP, which is convenient for home use, but not always suitable for retail locations, where the address must be permanent to communicate with inventory control systems.
In the configuration utility, go to the "Network" or "TCP/IP" tab. Here you can select the IP address acquisition mode: dynamic or static. If you choose a static IP, you will need to manually enter the IP address, subnet mask, and gateway.
It's important that the selected IP address is in the same subnet as your router, but not the same as other devices. For example, if your router has an address of 192.168.1.1, you can assign 192.168.1.55 to your cash register. Also, check your DNS settings if your cash register needs to access the internet to transmit fiscal data to the fiscal data operator (OFD).
| Parameter | Description | Example of meaning |
|---|---|---|
| IP Address | Unique address of the cash register on the network | 192.168.1.55 |
| Subnet Mask | Subnet mask | 255.255.255.0 |
| Gateway | Gateway (router) address | 192.168.1.1 |
| DNS | Domain Name Server | 8.8.8.8 |
After making changes, be sure to click the "Save" or "Save" button for the settings to apply. The cash register may reboot to accept the new network settings.
Testing the connection and printing a report
The final step in setting up is to test the connection. Don't rely solely on the indicators; you need to ensure that the cash register can actually transmit data. The easiest way to do this is to generate a payment status report or a test receipt with a network fiscalization flag.
In your sales software (1C, Frontol, or the Incotex test utility), try sending a print command. If the receipt is successfully printed, the connection is established. You can also generate a "Payment Status" report directly at the cash register by selecting the corresponding item in the reports menu, which often displays the connection status with the fiscal data operator (FDO).
If the cash register is connected to WiFi but isn't sending data to the fiscal data operator (FDO), the problem may not be with WiFi, but with the FDO settings or an expired fiscal data recorder (FN). Check the status of the fiscal data recorder.
Common errors and how to fix them
During setup, users often encounter a number of standard issues. One of the most common is the error "Driver not found" or "Device not responding." This usually means the wrong COM port is selected or the driver is not installed correctly. Check the device manager to see which port is assigned to the USB cable and specify it in the utility settings.
Another common issue is that the cash register sees the network but doesn't connect. This may be due to the frequency range. The WiFi module in Mercury 115F can only support standard 802.11 b/g/n On the 2.4 GHz frequency. If your router only broadcasts on the 5 GHz frequency or uses complex enterprise-level encryption methods, the cash register will not be able to log in.
⚠️ Attention: Avoid using special characters in the network name (SSID) and password if the cash register is older. Some firmware versions incorrectly handle characters such as spaces, quotation marks, or punctuation marks in WiFi passwords.
It's also worth mentioning the issue with the module freezing. If the cash register stops responding to network commands, try turning it off completely, disconnecting the power for 10-15 seconds, and then turning it back on. This reboots the network module and often resolves temporary glitches.
What should I do if the cash register loses connection after the salesperson leaves?
Check your router's power saving settings. Some routers turn off inactive devices. You need to reserve the cash register's IP address in your router settings (DHCP Reservation).
Security and Stability Recommendations
A wireless network is a potential vulnerability, especially when it comes to financial transactions. Make sure your WiFi network is protected by a strong encryption protocol, preferably WPA2-PSK or WPA3. Using legacy WEP or an open network is unacceptable for equipment processing payment data.
To improve stability, we recommend setting up a static IP address not only on the cash register but also reserving it in the router itself using the device's MAC address. This ensures that the cash register address will never change, even if you reboot the router, which is critical for settings in 1C and other accounting systems.
Regularly check the manufacturer's website for firmware updates. Developers periodically release patches that improve compatibility with new network equipment and fix security vulnerabilities.
Is it possible to connect the Mercury 115F to WiFi without a computer?
No, initial network setup (entering the SSID and password) is only possible using a computer with the setup utility installed and a USB cable. Entering complex WiFi passwords using the cash register keypad is not possible.
My cash register is displaying an error when connecting to WiFi. What should I do?
Check if your router supports b/g/n standards at 2.4 GHz. Try temporarily disabling MAC address filtering on your router and simplifying your password by removing special characters to test the connection.
Is internet access required for the cash register to operate in offline mode?
Internet access is not required to print a receipt at the time of sale (the data is stored in the fiscal drive), but a connection is required to transmit the report to the fiscal data operator (OFD). The cash register will attempt to send the data as soon as a connection is available.
How can I find the MAC address of my cash register to configure my router?
The MAC address of the WiFi module can be found by generating a configuration report at the cash register itself or by viewing the information in the WiFi configuration utility on the computer at the time of connection.
