Business owners often face the need to convert their cash register from a wired Ethernet connection to a wireless protocol. This allows for the placement of Mercury 185F anywhere in the sales area, avoiding cable length restrictions.
Setup process Wi-Fi module This requires careful attention, as the slightest error in the settings can lead to a loss of connection with the data operator. Before starting work, make sure you have access to the router and the wireless network password. You will also need a computer with the utility installed. Mercury TP or access to the web interface of the cash register itself.
In this article, we'll cover all configuration steps in detail, from checking drivers to entering data operator (OFD) settings. You'll learn how to avoid common password errors and what to do if the device isn't detecting your network. Proper configuration will ensure the smooth operation of your point of sale.
⚠️ Attention: Software and firmware interfaces are subject to update. If you don't see the button or menu described above, check the cash register software version in the "About Device" section and, if necessary, update it through the manufacturer's official website.
Preparing equipment and checking drivers
The first step is to ensure proper communication between the cash register and the personal computer. For initial setup Mercury 185F It's often more convenient to use a USB cable, as it provides a stable connection without the risk of data packet loss. Make sure the cable is in good condition and is firmly inserted into the ports.
You must install the latest drivers for the virtual COM port on your computer. Without this step, the configuration utility simply won't recognize the connected hardware. You can download the necessary files from the manufacturer's official website or find them on the included disc.
- 📥 Download the driver installation package from a trusted source.
- 🔌 Connect the cash register to your PC via USB and wait for the device to be detected.
- 💻 Check the Device Manager for the new COM port.
- 🛠️ Install the "Mercury TP" utility to manage parameters.
After installing the drivers, launch the setup program. In the connection window, select the appropriate COM port and click the connect button. If the connection is established, you will see the current firmware version and the fiscal storage device status.

Configuring network settings via PC
The main configuration is done in specialized software. Go to the "Network" or "Communication Settings" tab, where the TCP/IP parameters are located. Here, you need to switch the connection type to Wi-Fi Clientso that the cash register operates as a wireless network client.
In the SSID field, enter the exact name of your wireless network. Case is important: if your router is broadcasting the "MyShop" network, entering "myshop" will result in an authorization error. The password is also case-sensitive.
| Parameter | Default value | Recommended action |
|---|---|---|
| Connection type | Ethernet | Switch to Wi-Fi |
| IP mode | Static | DHCP is recommended |
| Server port | 5555 | Leave unchanged |
| Time-out | 30 sec | Increase to 60 for poor signal |
Pay special attention to your IP address settings. For most home and office routers, the optimal choice is DHCPIn this case, the router will automatically assign a unique address to the cash register, eliminating network conflicts. If your infrastructure requires static addresses, ensure the selected IP isn't already occupied by another device.
After entering all the data, click the "Save" or "Save" button. The cash register will reboot the network module. If you are using a static IP address, make sure the gateway and subnet mask match your router settings.
Configuration via the cash register web interface
An alternative and often more convenient method is to configure the settings directly from the cash register screen or through the built-in web interface. Accessing the admin menu usually requires a password, which is often set by default to 2 or 30, however, it is better to check this information in the device’s passport.
In the device menu, find the "Settings" section and go to "Network." Here you'll see a list of available wireless networks within range. Select your network from the list to ensure there are no errors in the SSID.
⚠️ Attention: When entering your password on the cash register screen, it's easy to make a mistake due to the small keyboard. Enter the characters slowly and double-check them before saving, as the cash register won't show any asterisks and will immediately attempt to connect.
If your network is hidden (not broadcasting its SSID), select "Other Network" or "Enter Manually." In this case, entering the router name accurately becomes critical. After saving the settings, the cash register will attempt to obtain an IP address.
A successful connection is indicated by a corresponding Wi-Fi icon in the upper right corner of the screen. If the icon is blinking or has a strikethrough, the password is incorrect or the signal is too weak to work reliably.
Registering and setting up OFD
After successfully connecting to the internet, you need to configure data transmission to the fiscal data operator (FDO). Without this step, the cash register will not be able to generate receipts in accordance with Federal Law No. 54-FZ. Go to the "FDO" section in the settings menu.
You will need to enter the OFD server address (usually this is a domain name, for example, ofd.ru or taxcom.ru) and port. This information is provided by your operator in your contract or personal account. You also need to enable receipt transfer by checking the "Enabled" box.
It's important to check the connection status with the fiscal data operator (FDO). The utility or the cash register screen should display a successful connection. If the status is "No connection," check that the server address is entered correctly and that the router itself has internet access.
- 📝 Enter the domain name of your OFD server.
- 🔢 Specify the connection port (default is 21194).
- ✅ Activate the option to transfer fiscal documents.
- 🔄 Click "Test Connection" to check the channel.
Be sure to set the correct time and date. Time synchronization is critical for fiscal documents. It's best to set up automatic synchronization via network time (NTP), if this option is available in your firmware version.
What should I do if the OFD doesn't accept receipts?
If the connection with the fiscal data operator (FDO) is lost, the cash register switches to offline mode. Receipts are saved in memory and will be sent when the connection is restored. However, it's not recommended to work in this mode for long periods of time, as the fiscal data operator's memory may become full.
Diagnostics and troubleshooting
During operation, situations may arise where the Wi-Fi connection suddenly drops. First, check the signal strength. If the cash register is located far from the router or behind thick walls, the signal may be unstable. In such cases, using a USB antenna with external amplification can help, if the cash register model supports it.
A common problem is changing the password on the router or changing the frequency range. Mercury 185F may not support the 5 GHz standard, operating only in the 2.4 GHz band. Make sure your router broadcasts a compatible network standard.
If the cash register isn't receiving an IP address, try rebooting the router. Sometimes the DHCP address pool becomes full, preventing a new device from accessing the network. Also, check if MAC address filtering is enabled on the router.
⚠️ Attention: When resetting your cash register to factory settings, all network settings, including the fiscal data operator (FDO) settings, will be deleted. You'll have to re-enter all data and re-sign reports.
To diagnose the problem, use the connection test in the cash register menu. It will show the ping to the gateway and the OFD server. If there is a ping to the gateway but not to the OFD server, the problem lies in the DNS settings or ports being blocked by your ISP.
