Note the following Network Requirements:

  1. Minimum Internet Speed recommendation of 5Mbps (Learn more here about WiFi requirements).
  2. Most standard consumer or business firewalls permit all outbound traffic as a default, in this case no changes are required and the steps below will just work.  If you have a managed firewall or enterprise firewall you need to ensure specific ports at the bottom of this page are enabled for outbound traffic. If you follow the terminal setup steps below and it does not work please verify your firewall permits the ports at the bottom of this page.

Firewall Port information (if-needed)

Do you have a firewall?

Note: If you have a firewall ensure that the following ports are open to allow traffic on your firewall. Otherwise this device will NOT communicate correctly.


Testing to confirm the ports are open
Run the following tests from Windows command prompt or Mac terminal to confirm these ports are open.

Port 9000 prod1.netepayhosted.dcap.com and prod2.netepayhosted.dcap.com
curl -vLI telnet://prod1.netepayhosted.dcap.com:9000
curl -vLI telnet://prod2.netepayhosted.dcap.com:9000

You should see this response:
*   Trying
* Connected to prod1.netepayhosted.dcap.com ( port 9000 (#0)

(note: the IP address may be different)


If there is no internet going to the device it does NOT give an error message - it will just show the triPOS logo. Make sure to verify the ethernet port is working by trying to connect the unit directly to your router, bypassing it and going to the modem, or plugging it into a wired port that you know is already working.

  1. Swipe up from bottom on PAX A920Pro
  2. Tap the arrow twice
  3. Enter the password: pax9876@@
