5. Troubleshooting
5.1. Why can’t the terminal talk to others?
1. Check the internal window intercom logs with regards to the server.
2. Check whether the mapping settings of the server are correct.
5.2. Why the terminal is “offline”?
1. Check the server software and the firewall. It’s advised to stop all firewalls before launching the software
on the server (including Windows built-in firewall and other antivirus software firewall).
2. Check the network connection. After the terminal has been powered on, the network port light should
normally be green. When the network port light is flashing orange (fast and slow), it means that the
network cable is connected normally. If the network port light is not green, it means a network related
problem. Please check the terminal network cable and LAN switch whether they work normal, not
damaged or disconnected etc.
3. Check the terminal IP parameters: terminal IP, terminal ID, sever IP, local IP, gateway IP, etc.
