Cash register equipment Mercury 115F While it's deservedly popular among small businesses due to its reliability and functionality, initial setup of the wireless module often presents difficulties for users. Modern requirements for online cash registers require a stable internet connection to transmit fiscal data to the OFD and EGAIS, making proper configuration difficult. Wi-Fi module A critical task. Unlike a wired connection, a wireless network allows for the cashier's workstation to be mobile and eliminates unnecessary cables, but it requires careful consideration when configuring security and IP addressing.
Activating the wireless interface in this cash register model is not a simple matter of clicking a single button, as it requires sequentially entering the router parameters and selecting the correct operating mode for the device. Incubation and production company "Shtrikh-M", the developer of this equipment, has provided several levels of protection and settings that must be activated correctly. Before accessing the cash register menu, you should prepare your local network information, including the exact SSID and password, as even a single character error will result in network authentication failure.
It's also worth considering that the cash register hardware may have different Wi-Fi adapter modifications, which sometimes affects compatibility with certain encryption standards or router frequency ranges. Security protocols WPA2 and WPA3 are the de facto standard, but older equipment may require specific settings for stable operation. In this article, we'll detail a step-by-step procedure that will help you avoid common mistakes and ensure the smooth operation of your retail equipment.
Equipment preparation and compatibility testing
The first step before starting setup is to physically check the presence and functionality of the Wi-Fi module installed inside the cash register. Not all configurations Mercury 115F Since the devices are equipped with a wireless adapter, a visual inspection or a check via the service menu is mandatory. If the module is missing, installing it will require opening the case. During the warranty period, this should be done by authorized service centers to avoid damaging the seals.
The second important aspect is the compatibility of your router with the technical specifications of the cash register. Most modern cash registers operate in the 2.4 GHz band, and attempts to connect to a 5 GHz network without the adapter's support will be unsuccessful. Make sure your router broadcasts on the correct frequency and uses supported encryption standards, such as AES or TKIP.
β οΈ Important: Before beginning any configuration, ensure the cash register battery is at least 30% charged and the device is connected to a power source. A sudden power outage while writing the configuration may damage the file system or reset the fiscal drives.
You also need to know the MAC address of your Wi-Fi adapter in advance if your network is configured to filter by hardware addresses. This unique identifier will need to be added to your router's whitelist; otherwise, the cash register will simply not receive an IP address, even if the password is entered correctly. You can obtain this information by printing a test configuration or in the corresponding section of the settings menu.
Navigating the menu and entering setup mode
To access network settings, you must switch to administrator or chief engineer mode, as the regular cashier mode does not provide access to system settings. This mode is usually accessed through a sequence of commands starting with the access password (often by default, this is 30 or 1), followed by selecting the corresponding menu item. The device interface may differ depending on the firmware version, but the logic remains the same across the entire line. FR.
After entering the administrator password, you'll need to find the section responsible for communication ports or network settings. Navigate the menu using the arrow keys, and confirm your selection with the [press/tap] button. VG (Input). It is important not to confuse the sections responsible for the USB port, RS-232 and Ethernet, since we are interested in the subsection Wi-Fi or "Wireless Network".
If you're setting up your device for the first time, we recommend resetting the current network settings to factory defaults to avoid conflicts with old configuration files. This will clear previously saved connection profiles and allow you to start setup from scratch, which is especially important when changing providers or routers. After resetting, your cash register may require a reboot for the changes to take effect.
Step-by-step instructions for connecting to a Wi-Fi network
The connection process begins by enabling the "Use Wi-Fi" option or a similar toggle in the settings menu. Once enabled, the cash register will scan for available space, and you'll be prompted to select your network from the list or enter a name manually. Manually entering the SSID is preferable if your network is hidden or has special characters in its name that may not display correctly in the list.
The key step is entering the security password, which requires strict adherence to letter case and character order. To enter special characters, use the button. Γ or WITH to switch input modes, as the standard cash register keyboard has limitations. A password error is the most common cause of connection failure, so double-check the entered data before confirming.
βοΈ Wi-Fi Setup Checklist
After entering all parameters, save the changes and wait for a connection attempt. The indicator on the register or the icon on the screen should change state, indicating authorization and IP address acquisition. If the status doesn't change to "Connected" after 10-15 seconds, there was an error at one of the handshake stages.
| Parameter | Recommended value | Description |
|---|---|---|
| Opening hours | Infrastructure (Station) | Connecting to a router |
| Encryption | WPA2-PSK | Safety standard |
| DHCP | Included | Automatic IP |
| Port | 5555 or 9999 | Driver port |
Setting up static IP and DHCP
In most cases, the dynamic addressing mode is sufficient for the cash register to operate. DHCP, when the router automatically assigns an IP address to the device. However, in corporate networks or when using complex port forwarding schemes for cash register drivers, a static IP address may be required. A static address ensures that the computer running the cash register software will always "see" the cash register at the same address, regardless of router reboots.
To set a static address, go to the advanced TCP/IP settings and disable the DHCP option. This will enable the fields for entering the IP address, subnet mask, gateway, and DNS servers. The cash register address should be on the same subnet as your computer, but not the same as any other device on the network to avoid address conflicts.
β οΈ Important: When using a static IP, ensure the selected address is not within the range of addresses assigned by the router's DHCP server. For example, if the router assigns addresses from 192.168.1.100 to 192.168.1.200, assign the cash register address 192.168.1.50.
Don't forget to check your gateway settings, as this is how your cash register connects to the global network to transmit fiscal data. An incorrect gateway will result in your cash register operating on your computer's local network but unable to connect to the fiscal data operator (OFD) servers, resulting in a backlog of unuploaded documents and potential fines.
What to do if IP addresses conflict?
If you see a message about an IP address conflict on your network, disconnect the cash register from the network immediately. Access your router settings from your computer and change the DHCP range or reserve an address for the cash register's MAC address so that the router doesn't try to assign it to another device.
Working with drivers and cash register programs
After successfully connecting to Wi-Fi, you need to configure the software on your computer that will control the cash register. In the driver KKT Mercury Using a compatible program (1C, Frontol, Shtrih-M), you need to create a new connection, selecting the "Ethernet" or "TCP/IP" type. In the device address field, enter the IP address you specified or received from the cash register via Wi-Fi, and the port must match the settings on the cash register itself.
An important point is to check the ports: the standard port for drivers is often 5555, but in some configurations Mercury 115F can use port 9999 or other values. If the connection test fails, try changing the port in the driver settings or check if Windows Firewall is blocking incoming connections to this port.
For stable operation, it's also recommended to disable the Wi-Fi adapter's sleep mode in the cash register settings, if this option is available. Power saving can cause the connection to drop after a period of inactivity, requiring a reconnection for each new receipt, slowing down the cashier's work.
Diagnosing problems and testing connections
If the connection fails, the first step is to run a test network configuration printout directly from the cash register. This report contains all the latest information about the module status, signal strength, received IP address, and errors from the last connection attempt. Analyzing this report allows you to pinpoint the problem: either the cash register isn't detecting the router, isn't authorizing, or isn't receiving an address.
Signal strength (RSSI) is a critical parameter for wireless POS systems, as connections below -75 dBm can be unstable. If you experience a weak signal, try moving the POS closer to the router or consider installing an additional repeater, as metal structures within retail equipment can block the signal.
In the case of persistent errors, an effective solution is to completely reset the network settings of the cash register and router, then reconfigure them from scratch. Sometimes updating the Wi-Fi module firmware helps if the manufacturer has released a patch to improve compatibility with new router models.
Why can't the cash register see my Wi-Fi network?
Most likely, your cash register only operates on the 2.4 GHz band, and your router only broadcasts on the 5 GHz band, or the network name (SSID) contains Cyrillic characters that are not supported by the module. Also, check if MAC address filtering is enabled on your router.
How can I find out the IP address of my cash register if it is already connected?
Perform a test print of the configuration ("KKT Status Report" or "Connection Test"). The current IP address will be displayed in the network settings section. This information can also be obtained through the "KKT Driver Test" utility in device search mode.
Is it possible to connect the cash register to public Wi-Fi?
Technically, this is possible if the network doesn't require authorization via a web page (Captive Portal). However, using public networks to transmit fiscal data is unsafe and not recommended due to the risk of information interception.
What does the "No connection to FN" error mean when setting up Wi-Fi?
This error is usually not directly related to Wi-Fi, but can occur if the cash register is malfunctioning. Check the integrity of the fiscal storage device cables and ensure the fiscal storage device cover is closed correctly. Network settings should not affect the physical connection to the fiscal storage device.
Do I need to reflash my cash register to work with a new router?
In 95% of cases, a firmware update is not required. Simply enter the new network parameters correctly. A firmware update is only necessary if your current driver or firmware version has known bugs with specific router models.
