Managing Hard Links

The device must have network connectivity with the Core(s) to which you wish to gain remote access. This can be via VPN or some other method suggested by your network administrator.

Note: Do not create hard links if your device can already discover the Core – that is, receive multicast packets from the Core.

Q-SYS Designer requires TCP port 443 and HTTP Hard Links to communicate with the target Core.

Q-SYS UCI Viewer requires the following ports to communicate with the target Core:

• TCP port 80 - supervisory functions
• TCP port 1700 - control messaging
• UDP port 6504 - discovery

In addition, the PC must be able to exchange ICMP (ping) echo messages with the Core. There are separate firewall settings to enable or filter these messages.

Testing Connectivity

You can test network connectivity by pinging the Core from your PC using the Windows command line interface (cmd.exe) and the Core's IP address. The format is ping ip_address. For example:

ping 123.45.6.789

If you get a good response – for example, "Reply from 123.45.6.789: bytes=32 time<1ms TTL=64" – you have the proper connectivity.

1. Close any open instances of the UCI Viewer.
2. Select File > Preferences > Hard Links from the Q-SYS Designer main menu.
3. To create a new hard link:
   1. Click the button at the bottom of the dialog box.
   2. Enter the IP address of the Core to which to connect.
   3. Click OK to save the new IP address.
4. To manage existing hard links:
   • To edit a hard link, double-click an existing entry and specify a new IP address.
   • To delete an existing hard link, select a hard link and click the button.
   • To toggle a hard link on or off, select or deselect the check box. This is useful when moving between network locations.
5. Select the Mode for all hard links: UDP or HTTP. For HTTP, both HTTP and HTTPS requests are attempted.
6. After creating the required IP addresses, close all open instances of Q-SYS Designer. You can then:
   1. Reopen Q-SYS Designer, and connect to the Core using Load from Core and Connect or Save to Core and Run.
   2. Open the Q-SYS UCI Viewer, and then select a UCI from the UCI Browser.

1. Close any open instances of Q-SYS Designer.
2. Open Q-SYS UCI Viewer.
3. Within the toolbar, click (Edit Hard Links).
4. To create a new hard link:
   1. Click the button at the bottom of the dialog box.
   2. Enter the IP address of the Core to which to connect.
   3. Click OK to save the new IP address.
5. To manage existing hard links:
   • To edit a hard link, double-click an existing entry and specify a new IP address.
   • To delete an existing hard link, select a hard link and click the button.
   • To toggle a hard link on or off, select or deselect the check box. This is useful when moving between network locations.
6. Select the Mode for all hard links: UDP or HTTP. For HTTP, both HTTP and HTTPS requests are attempted.
7. Close the Hard Links window, and then select a UCI from the UCI Browser.

1. Select Settings on the device
2. Under Apps, select Q-SYS Control. The Hard Link IP addresses list displays
3. Touch one of the IP address lines. The keyboard displays
4. Enter the IP address of the Core to which to connect. You must enter the periods along with the numbers.
5. You can continue adding IP addresses as required.
6. When you are finished, close the keyboard, and the settings menu.
7. Start the Q-SYS Control App. A list of available UCIs displays.
8. Select the one you wish to run.
