Modern retail outlets require mobility and independence from wires, so the question of how to connect a PSB terminal to Wi-Fi is becoming a priority for many entrepreneurs. POS devices Promsvyazbank's terminals are often based on the Android platform, which allows for the use of standard wireless protocols for transmitting transaction data. This frees cashiers from being tied to a specific location and allows them to accept payments directly at the customer's table or at the drive-thru.
The setup process may seem complicated at first glance, as the interface is protected from accidental changes by regular users. However, with administrator access or the default passwords, you can quickly put the device into operation via wireless networkIt's important to understand that connection stability directly impacts payment speed and customer satisfaction.
In this guide, we'll cover all the details of connecting various terminal models that work with PSB acquiring. We'll cover standard setup scenarios, potential errors, and troubleshooting steps to ensure your business runs smoothly. The key point is to strictly follow the sequence of actions when entering the router password, as the system is case-sensitive.
⚠️ Please note: The bank may update the terminal software interface remotely. If the menu items described below differ from what you see on the screen, please contact PSB technical support for the latest instructions for your software version.
Equipment preparation and compatibility testing
Before you begin setup, you need to make sure your equipment is technically ready for wireless operation. Not all bank-issued terminal models are equipped with the module. Wi-FiSome of them operate exclusively via a SIM card (GPRS/3G/4G) or a wired Ethernet connection. Carefully inspect the device's casing or refer to the documentation for the presence of an antenna or the corresponding logo on the front panel.
You will also need a working access point with known parameters. You will need to know the exact network name (SSID) and a password to connect. Make sure your router is broadcasting a 2.4 GHz signal, as many banking terminals, including popular models, PAX or Ingenico, may not support newer 5 GHz standards due to hardware limitations.
Check the terminal's battery charge. The process of network discovery and handshake establishment may require more power than normal operation. If the device is low on battery, connect it to a power source to prevent it from shutting down unexpectedly during a critical setup phase.
Logging into the terminal administrator menu
Changing network settings isn't possible with the standard user interface. You need to access a hidden configuration menu, which is protected by a PIN code. This usually requires pressing a specific key combination or selecting a hidden function in the menu. On many PSB devices, this is done by pressing the green confirmation button or a dedicated function key.
After calling the menu, the system will request an administrator password. By default, PSB terminals often use standard codes, such as 0000, 1234 or 0404If these combinations don't work, the password may have been changed during the initial installation of the equipment, and you'll need to look for it in the accompanying documents or check with your bank.
After successful authorization, you will see the main settings menu. Find the section responsible for communications. It may be called Settings, Communication or System SettingsThis is where switching between connection types occurs.
What to do if the administrator password does not work?
If the standard codes 0000 or 1234 don't work, don't try to guess the password multiple times. After several unsuccessful attempts, the terminal may become locked. In this case, the only solution is to call PSB technical support to reset the settings or obtain a custom access code.
Step-by-step instructions for connecting to a Wi-Fi network
In the settings menu, select the option related to network management. Depending on your terminal model, this may be the tab Wi-Fi, Wireless or Net. Activate the wireless module by moving the switch to the position On or OnThe device will begin searching for available networks within range.
From the list of found networks, select your access point. Click on the name of your router. If the network is hidden, select the option Add a network and manually enter the SSID. After selecting the network, a password entry field will appear. Be careful: use Latin characters and pay attention to the case of letters.
After entering the password, click the connect button. The terminal will attempt to obtain an IP address from the router. A successful connection is usually indicated by a Wi-Fi icon at the top of the screen or a message. ConnectedIf the connection is established, the device may prompt you to check for a software update or synchronize the time.
☑️ Connection checklist
Setting up static IP and DNS
In some cases, dynamic address acquisition (DHCP) may be unstable, especially in corporate networks with complex architectures. In this case, manual network settings are required. To do this, select the configuration type in the Wi-Fi settings. Static (Static) instead DHCP.
You'll need to enter the IP address, subnet mask, gateway, and DNS servers. You can find this information by connecting your computer to the same network and viewing the connection properties, or by asking your system administrator. An error in one digit of the IP address will prevent the terminal from "seeing" the internet, even if the connection to the router is established.
Pay special attention to the field DNSProblems connecting to bank servers often arise due to incorrect domain name addresses. Try entering Google's public DNS (8.8.8.8) or Yandex (77.88.8.8), if corporate settings do not work.
| Parameter | Description | Example of meaning |
|---|---|---|
| IP Address | The unique address of a device on the network | 192.168.1.150 |
| Subnet Mask | Subnet mask defining the range | 255.255.255.0 |
| Gateway | Gateway (router) address | 192.168.1.1 |
| DNS 1 | Primary name server | 8.8.8.8 |
Diagnostics and troubleshooting
Even with the correct settings, errors can still occur. One of the most common issues is when the terminal sees the network but fails to connect. This often indicates an incorrect password or incompatible encryption type. Make sure your router uses standard security protocols. WPA2-PSK, which are guaranteed to be supported by banking equipment.
Another common situation: Wi-Fi is on, but transactions aren't going through, and a connection error with the host appears. In this case, the problem may not be with the local network, but with the time settings. Check the date and time on the terminal. If they are incorrect, a secure connection to the bank will fail due to a security certificate mismatch.
It's also worth checking the signal strength. If the terminal is far from the router or there are many metal obstacles between them, the data transfer speed may be insufficient to process the payment. Try moving the device closer to the signal source or using a Wi-Fi repeater.
⚠️ Caution: Do not use open public Wi-Fi networks in cafes or shopping malls to connect to a banking terminal. These communication channels are unsecured, creating a risk of interception of your customers' card data. Use only private, secure networks.
Switching between Wi-Fi and SIM card
Many modern PSB terminals are hybrid and allow switching between wired/wireless internet and mobile internet. This is a useful feature for data backup. If the primary channel (Wi-Fi) fails, the device can automatically switch to the SIM card, ensuring uninterrupted cash register operation.
To set priorities, you need to go to the communication channel selection menu. Here you can check the box Wi-Fi Priority or a similar option. In this mode, the terminal will constantly monitor for the presence of a configured wireless network and use it by default.
If Wi-Fi is unavailable, the device will automatically switch to mobile data. It's important to monitor the balance of the SIM card installed in the terminal to ensure the backup channel is available in a critical situation. You can check your balance through the terminal menu or the bank's smartphone app.
Frequently Asked Questions (FAQ)
Is it possible to connect the PSB terminal to 5 GHz Wi-Fi?
In most cases, older and mid-range terminal models only support the 2.4 GHz band. If your router only broadcasts the 5 GHz network, the terminal simply won't detect it. It's recommended to configure a guest network or a separate SSID on your router specifically for the 2.4 GHz band.
The terminal says "No connection to the server," even though Wi-Fi is connected. What should I do?
Check the date and time on your device. If they are incorrect, SSL certificates will not be validated. Also, make sure your router doesn't block ports required for acquiring or restrict MAC addresses.
Are Wi-Fi settings reset when the terminal is rebooted?
No, the network profile is saved in the device's memory. After turning the device off and on, it should automatically connect to the previously selected network if it's within range and the password hasn't been changed.
How to find out the IP address of a terminal on a Wi-Fi network?
Typically this information can be found in the section About the device or Network status in the settings menu. The IP address is also often displayed in the list of connected clients in your router's admin panel.
