3. The Matrices
Throughout these instructions a stand alone Matrix can be considered as
a Master Matrix with no Slaves.
Each Master Matrix has 48 video inputs, 16 video outputs, 8 serial ports
for control of VCRs and multiplexers, a Centronics™ parallel printer
port, a network connector, a power connector and a screw-fitting earth
terminal.
A PY-32S (Slave Matrix) does not have serial or printer ports.
Figure 1. Matrix Connections (PY-48M16)
The Master/Slave feature allows a combination of up to 3 Slaves and a
single Master to behave as if they were one 144 video-input, 16 video-
output Matrix.
The purpose of a slave is to increase the number of video inputs into the
master matrix. To do this it must be situated adjacent to the master
matrix.
