6. Setting Up Machine Control Routers
An Overview of Machine Control Routers
Viewing Machine Control Router Crosspoints
The display of machine control matrices is different from that of other matrices.
Figure 6-1. View Router Crosspoints Page
In this matrix, ports 4 and 7 are connected. The square (A) at row 4 and column 7 is highlighted.
The square (B) at row 7 and column 4 is also highlighted.
If the two ports (in this example, ports 4 and 7) are dynamic ports, then clicking box A and clicking
box B give different results. Either way connects ports 4 and 7, but clicking box B makes port 7
controlled whereas clicking box A makes port 7 controlling.
A controlling port is defined as one that is connected to a controlling device. A controlled port is
one connected to a controlled device.
A dynamic port is one that can change. If a port is not dynamic, its configuration does not change.
S Clicking box A has the same effect as pressing destination (DST) 7 then source (SRC) 4 on a
panel.
S Clicking box B has the same effect as pressing DST 4 then SRC 7 on a panel.
In general, clicking column C, row R has the same effect as pressing DST C then SRC R: columns
are destinations and rows are sources.
When a port is on the diagonal, it is tri-stated or disabled. It neither transmits nor receives. Clicking
a column head for a machine control router is a no-op.
Machine Control Router Port Types
A device can be considered a “controlled” device or a “controlling” device. A controlling device
sends commands to a controlled device. The controlled device passes responses (such as status)
back to the controlling device. Both source devices and destination devices can be a controlling
device or a controlled device.
