To Control MC3648
MC3648 is a 4×8 matrix switch and contains 32 two-wire crosspoints. Each
crosspoint relay has its own unique channel label representing the row and column.
For example, channel 24 represents the crosspoint connection between row 2 and
column 4. This module does not connect to DMM. You can close multiple channels
and connect multiple inputs to multiple outputs at the same time. Before making any
connection, make sure that the connection will not introduce any danger.
