Follow the same process above for the POS tablet.
Both devices should be connected to the same WIFI.
Please check the IP address of the CDS.
Check the IP address of the Octopos Customer Display Screen (CDS) by opening the OctoCDS APP and clicking the blue target logo rapidly (6 to 8 times).
Check the IP address on the settings menu that just opened up(make a note of the address), then click submit.
Open the menu on your POS tablet.
Open the update settings menu from the selection.
Scroll down to the Customer Display and make sure that the entered IP address is the same as the CDS IP address checked in the previous step and click on submit.
CDS IP: The IP address here should be the same as the CDS IP address checked in the upper steps. To resolve the issue, restart both your POS and CDS tablet. First, turn on the OctoCDS app on the CDS tablet. Then, start the POS and log in. Please note that this process will not work if the POS was kept on while restarting the CDS or if the POS was started before the CDS.
