Identifying Input / Output Ports
Matrix cards that are installed into the card slots on the MTX3-16-M, include input and/or
output ports. Each card slot has 2 port ID numbers to be assigned to the inserted card. In total
there are 16 port IDs available. Port input/output directions are defined per port ID number.
A single matrix card can have both input and output ports.
The port ID numbers are written on the chassis, next to each card-insertion point. Ports on the
left side of the card use one port ID number and ports on the right side of the card use the
next port ID number.
Cards can have up to 4 ports. If a card has 4 ports, the 2 on each side of the card use the
same ID number.
