Each computer that connects to your ACR system is assigned a Port Number, this is a unique number that is used for identification not only of your computer but also information that was created on your computer like parked sales and orders. The Port Number also holds configuration details like what default Stock Area your computer uses and if you have a cash draw/till printer attached. A Port Number is linked to the computer name your IT people would have given your computer when setting it up.
As the computer name and Port ID are linked it is highly recommended that when replacing a physical computer with a new physical computer that the new machine is given exactly the same computer name as the old one. This will allow ACR to recognise it as being the same Port Number. This means that any parked sales or orders will still be available as well as your configurations will remain the same and not need to be reset.
If you are replacing the existing computer with a new computer and need to change the computer name please contact ACR Response support to discuss how to minimise the impact that a change of Port Number may have on your staff.
