MADI Port Parameters
"System -> Definition -> Parameter = Madi"
Open this branch of the 'Tree Definition' to configure parameters for the MADI ports.
Parameter
Madi – reference name for the element.
P1, 2, 3, 4 External
This is a project-specific feature.
Matrix Port
Server 1 active
These options support a redundant matrix server.
Server 2 active
Assign a control signal to switch to server 1 or server 2.
P1 Enable 64 Tx Slots
When this checkbox is selected, the MADI port transmits 64 slots as opposed to 56.
etc.
Note that the receiver automatically detects whether 56 or 64 slots are supplied. If the port is
configured to transmit 64 slots and only 56 are received, then the last 8 slots are muted.
The option can be selected for each individual MADI port.
P1 Select Input 2
Click to assign a control signal to switch the MADI port from P1 to P2.
etc.
Note that if
The option can be selected for each odd/even pair of MADI ports.
P2 Tx = P1 Tx
When this checkbox is selected, MADI port P2 transmits the same data as port P1. The option
can be used to configure redundant MADI outputs.
etc.
The option exists for each odd/even pair of MADI ports.

Creating Redundant MADI Ports
To create redundant MADI links with automatic switching from say MADI Port 1 to Port 2:
1.
Invert the P1 Input present control output using a
2.
Then feed the output of the NOT gate to the P1 Select Input 2 control input.
Now if the signal input to MADI P1 fails, the system will automatically switch to MADI P2.
3.
To configure redundant MADI outputs, check the P2 Tx=P1 Tx option.
Now MADI port P2 transmits the same data as port P1.
You can use this procedure to configure each odd/even pair of MADI ports.
