TRIOS Share Network requirements guide can be found here.

Find below a detailed description of all the network parameters and their influence on TRIOS Share performance.

Wireless networking standard and frequency

802.11ac Wi-Fi is a wireless networking standard that Share uses. It is also known as Wi-Fi 5.

It's limited to work with 5GHz frequency band only. 

2.4 GHz frequency is not officially supported.

If the customer has a router that supports 2.4 and 5 GHz frequencies at once with the same network name, it's recommended to:

  • Either disable 2.4 GHz frequency on a router;
  • Or give 2.4 GHz frequency network another name.

If the network has multiple access points, then it's important to ensure that they use different frequencies/channels.

Channel bandwidth

Each frequency band is divided into channels. An access point can be configured to use a specific channel that will be used to communicate with connected devices. 

A wider channel means that more data can be sent at the same time.

TRIOS 5

Maximum bandwidth

90 Mb/s

Scanning bandwidth

46 Mb/s

TRIOS 3 and 4

Maximum bandwidth

70 Mb/s

Scanning bandwidth

36 Mb/s


The higher bandwidth is mostly needed when having multiple scanners on the network and the other way around.

Bi-directional traffic

Bi-directional traffic shall be permitted since data is sent from the scan PC to the scanner and from the scanner to the scan PC.

TRIOS Share will not work if it is not permitted.

Communication ports

The following TCP ports are used on the scanner: 20-21, 80, 23795 and 23796

The following UDP ports are used on the scanner: 58218 and 58220-58230

The following UDP ports are used on the PC or router: 67 (DHCP), 5353 (mDNS)

All the above ports should be open, otherwise, the scanner will not connect.

mDNS

mDNS is the protocol specifying how to discover the scanner on the network.

Should be enabled, otherwise, the scanner will not connect.

Redirection of traffic done for example by Captive Portals must be disabled

A captive portal is a web page accessed with a web browser that is displayed to newly connected users of a Wi-Fi or wired network before they are granted broader access to network resources.

Some portals redirect the traffic and in that case Share will not work.

WPA2-PSK authentication for TRIOS scanners

There are three security programs developed by Wi-Fi Alliance:

  • WPA
  • WPA2
  • WPA3

There are also the following two types of security programs:

  1. WPA-Personal: Password configured on AP (3Shape Guest)
  2. WPA-Enterprise: has client authentication using authentication server:

Currently only WPA2-personal is supported by TRIOS scanners.

Windows firewall

Windows firewall rules are added to the PC's firewall as part of the installation process of Dental Desktop so usually, no further configuration is required.

Direct line of sight

Each scanner should have a direct line of sight to an access point to ensure good Wi-Fi coverage in the scanning location.
