Data Routing
Data Routing
A solid state router is used mainly for machine control, such as to assign
VTRs to an edit controller. RS422 uses four wires with one pair used for the
transmit signal and the other pair for the receive, so the router handles both
a forward and a reverse signal path through the matrix. It can be supplied
equipped for 8x8 or 16x16.
Inputs
The RS422 inputs are terminated in 110
Ω
. Inputs 1–8 are installed on the
main matrix module and Inputs 9–16 on a submodule.
Crosspoints
A single crosspoint chip has the capacity to switch 16 inputs to the 16
outputs.
Outputs
The output drivers are designed to drive 110
Ω
lines.
The module has the capability of 16 outputs, but for systems with 8 outputs
it is installed with only 8 output stages.
