Serial Matrix

RoutingSerial Matrix

This device can embed serial data in a MADI stream is using the user bits 1 — 9. The serial matrix allows you to de-embed and route this serial data separately from the audio routing. The MADI ports that take part in a serial routing do not have to be synchronous.

If you connect audio channels 1 — 9 from one port to another port and disable serial routing in this matrix, you can achieve the same since channel user bits are routed as well. But in this case both channels have to be synchronous.

Using the matrix

To make a connection between an input port (rows) to an output port (columns), just click in the square that intersects both. If you press on the same square again, you can toggle between the N/C and connected state.

Note: You may notice a lag in the 100ms range between clicking on the matrix and the connection to show up. The matrix always shows the state inside the router and the transfer forth and back takes about this time. On the plus side, you always see what is going on inside the device.

Above the matrix you have a small toolbar:

Setting the bitrate

Routing serial data from one MADI stream to another can be accomplished not knowing the bitrate of the underlying data stream. But if you want to route to or from a hardware port, the bitrate has to be set.

Serial bitrate

In order to do this, choose the bitrate for (both directions of) the port you want to use in your routing from the corresponding checkbox on the left. You can choose between 9600, 19200, 38400 and 115200 bits/s for each port independently.
