3.3 GRID PAGE / ROUTING SIGNALS  

3.3.1  Grid Page Presentation 

 
The Grid page allows to route all signals available on the network (peer to peer or distribution) 

 
The routing crosspoints are filtered by signal type with the dropdown menu above allowing to switch 
between matrix for the Video, Audio, AES, MADI, GPIO, IP or Serial channels. 
 
In the grid, signals listed vertically correspond to all input signals available and configured, while all signals 
listed horizontally correspond to output signals. These ports are grouped per Stage Racer 2 units for easier 
filtering. 
 
The port name labelling is formatted in the following manner of “Physical Port Type-Number” “[Input Signal 
Type]” l “User Label”.  For example: 

SDI-3 [12G] UHD Monitor

 

 
The Green / Red dot indicates signal presence on each port.
