Both matrix and LQ must be connected to a network and able to reach each other across the network settings.
To set up this connection:
Generate IVC-32 ports in EHX
1) From the EHX configuration software, navigate to Port Settings and generate new IVC ports. You need to define a
    User ID and Password for each new port, as these will be given to the LQ device, along with the IP address of the
    IVC-32 card.
2) When you have generated new IVC ports, click Apply changes to Matrix.

Generate IVC-32 ports in the CCM
3) Navigate to CCM > External Systems. Add IVC-32 card.
4) Enter IVC-32 IP address and TCP/IP port number.
5) Add IVC-32 ports.
6) Give the port a label (can be any meaningful description). Enter User ID and Password. These must be exactly the
    same as declared in the EHX interface.
7) Select an LQ unit for the ports.
8) A Green LED shows when the connection is working. Click gear icon to go to port settings. If the connection light does
    not show, a yellow error triangle shows. Click on this for known error conditions.
Note: You can create unlimited instances of IVC-32 cards and ports in the CCM. However, a maximum of 8 IVC-32 ports per
LQ device can be connected at any one time. A total of 32 IVC-32 ports can be used in a Link-Group at any one time (provided
the assignment does not exceed the processing power of the devices, in which case the CCM gives a warning and disallow it).

Add ports to a Channel
When you have created instances of IVC-32 ports in the External Systems page you can navigate to Assignments and add ports
to a Channel.
