If the active elements that provide network coverage and Internet connectivity in your establishment are not properly selected and set up, problems with the POS system can occur. These include communication failures between the cash register and other devices such as payment terminals or mobile waiters, or card payment failures. Alternatively, real-time cash register transactions are not being transmitted to Dotypos Cloud. Thus, a stable and properly configured network in the establishment is very important for the functioning of Dotypos and their POS peripherals.
|
The quality of network coverage of the premises and the appropriate network setup are purely the responsibility of the customer and Dotypos is not responsible for them. |
An improperly built or configured network or an unstable internet connection will manifest itself in the following symptoms:
•In Dotypos, the cloud icon on the main screen lights up red to indicate a connection to Dotypos Cloud. This means that the synchronization between the cash register and Cloud is not taking place.
•The LAN/WiFi printer does not print receipts or orders, or the printing drops out irregularly.
•Mobile waiters have long response times, you have to wait a few seconds to move or close the account.
•Card payments do not go through connected payment terminals.
•Dotypay payment terminals report a connection error to the transaction center during payment.
•During heavy traffic, the entire POS system experiences long response times.
If your establishment is experiencing the issues described above when using Dotypay, mobile waiters or payment terminals, we recommend paying attention to proper network setup.
|
The easiest and fastest way to verify that POS system problems are not caused by the network in your establishment is to use a hotspot. Turn on the hotspot on any mobile phone with data services and temporarily connect the cash register and other POS peripherals to the hotspot. If everything works properly on the hotspot, you need to focus on adjusting the network at your establishment. |
Requirements for the network environment for the Dotypos
|
Separate standalone wireless network for cash registers and cash register peripherals. We highly recommend using separate active elements (routers). For example, one for the customer network and the other for the Dotypos system. Remember to protect both networks with at least WPA2 level encryption. |
|
Printers of receipts and orders connected by an uninterrupted Ethernet cable directly to the router. |
|
A channel of a dedicated wireless network configured so that it is not overlaid by the range from other channels. If your Wifi router uses e.g. channel 1, the next network should use a channel +2 higher (or lower) i.e. at least channel 3, better 4. |
|
If you cannot use a separate router, you must reserve a separate IP address range for each POS device outside the DHCP server. This is because it is necessary that each device (cash register, payment terminal, mobile waiter, customer display) has a static IP address assigned to it. It is also imperative that the router can handle creating two separate Wifi networks, one for the Touch and one for visitors. However, we strongly advise against a single shared router solution, primarily for capacity reasons. |
|
Enable TCP/UDP ports 7500, 443, 7921 and 37690 on the router, which are necessary for communication of Dotypay payment terminals. The router should also support Network Service Discovery (DNS-SD (service discovery) + Multicast DNS (mDNS) protocols). Packet loss should be < 10%, ping < 10 ms. |
|
Do not mix network elements from different brands and suppliers. Always use network devices (routers, APs) from only one manufacturer. |
|
If you are using Access Points (APs) to cover your premises and there is a delay when switching from one AP to another, try setting the minimum signal strength at the individual AP level (RSSI). |
