To connect an RS-485 connector on one unit to an RS-485 connector on one
or more other switchers (from the series of 16x16 matrix switchers), as Figure
12 illustrates:
1. Connect the “+” PIN on the first unit to the “+” PIN on the second unit or
other unit
2. Connect the “-” PIN on the first unit to the “-” PIN on the second unit or
other unit
3. If shielded cable is used for an RS-485 connection, connect the shield to
the Ground PIN.
For details about how to configure the vertical sync (if required), refer to
