First areas to look:
- Is the tablet connected to the internet, pull up a site from your browser to verify
- Verify that the IP address is "Standard" to pair it with the Tablet. Should be in the normal format, such as 192.168.001.139
- Verify that the IP address is entered in the tablet without lead zeros. If the IP address in the Pax is 192.168.001.139 enter it as 192.168.1.139 (followed by the port ).
- It would be entered as (Ex: 192.168.1.139:10009)
The Application in the PAX should have a https Get Command for communicating with the Tablet (this is set up by your processing company)
