If you are seeing a '7502 balance server error' on your terminals.
First point of call here is to do some checks;
- Confirm the till terminal which acts as the balance server is running (one of the tills will be set as the balance server which the other tills point to).
- If this is only affecting the one till terminal, it's making sure your terminal has not dropped network connection by minimize out of GPOS and make sure no red cross is displaying within the network monitors on the toolbar. If not, shutdown GPOS and relaunch to pick up the balance server again.
- If this fails to work and it's happening on all terminals, confirm the balance server terminal is on the network or give the main till a restart followed by starting the other tills to repoint to the balance server till terminal.
- If you have found all tills have dropped network connection and no active network, at this stage to speak with your local IT who look after your network.
