Please refer to the SkyTab Customer Site Readiness Guide for additional details regarding port numbers, IP addresses, and network configuration.

Network Requirements

The wireless requirement for a SkyTab device is simple:

• Steady Internet Connection
• 5mbps Upload
• 5mbps Download

SkyTab supports the Wifi network type 802.11 b/g/n, 2.4GHz, 802.11ac、b/g/n, 5GHz. 

The bandwidth requirement is minimal and normal operation can function with no impact with as little as a 64k connection. However, with the apps being about 10 to 20 MB each, there may be some impact on the bandwidth when the app needs to be updated.

Required Ports 

Contact your ISP provider to ensure ISP is not blocking any of the ports on your side.

Internal:

The following ports are needed for various purposes: 

• Port 123 and IP Address time.google.com is needed for terminals to call out to Google's NTP server to keep accurate Time and Date
• Port 7135 and Port 7136 are the ports that Mozart https://mq.mozart.shift4payments.com/ use to communicate locally with the on-site POS, so they need to be granted access on the merchant's LAN
• The outbound Port 5672 is needed for Mozart https://mq.mozart.shift4payments.com/ processing.
• Need access to Port 9080 and Port 3000 for SkyTab to be able to communicate with the PAXStore https://auth.paxstore.us/passport/login?client_id=admin&market=shift4
  • Note: Ports 9080 and 3000 need to be outbound only.
• Our Gateway http://utg.shift4api.net/ uses Port 443 for processing and access to Lighthouse https://lighthouse-api.harbortouch.com/

IP Address

Set the C7 router to 192.168.213.2, which puts both routers on the same subnet. Both routers can be used to connect additional Harbortouch devices. 

Disable DHCP server on the C7 router to ensure that your existing TP-Link router still maintains the responsibility of issuing an IP address. This adverts any possibilities of IP Conflicts caused by two DHCP servers issuing out the same IP addresses to different devices.
