Before you attempt to make uniCenta oPOS Configuration changes: You must have MySQL Server 5.7 installed and running correctly.
Watch this video to see how to install MySQL Server
The most essential setting is that you have a MySQL server installed, set up, and running correctly. Without it you cannot run uniCenta oPOS.
As uniCenta oPOS evolves you may find that new options are shown on the Configuration panel tabs and not shown here. Please refer to Release Notes and documents that accompany each release.
If you find your are Configuring for the first time, our advice is to take things step-by-step and try not to feel too intimidated. Follow the steps on this page and you won’t go far wrong.
If you’re upgrading it’s recommended you read the upgrade page.
There are a few things that need to done if this is a new uniCenta oPOS installation. If an upgrade, most previous existing settings will be there – in some cases they are not – so you will need to review and adjust where necessary. Either way it’s a good idea to be prepared before embarking on the set up.
The next important setting is Printers, you will find on the Peripherals tab, and whilst not an essential setting to get you up and running right now it’s worth a bit of effort to save you having to revisit later.
