Figure 15 defines the RS-485 connector PINOUT for external RS-485

Figure 15: RS-485 Connector PINOUT
To connect an RS-485 connector on one
VS-1616V
unit to an RS-485
connector on one or more other switchers (from the series of 16x16 matrix
switchers), as Figure 16 illustrates:
1. Connect the “+” PIN on the first
VS-1616V
unit to the “+” PIN on the
second
VS-1616V
unit or other unit
2. Connect the “-” PIN on the first
VS-1616V
unit to the “-” PIN on the
second
VS-1616V
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
section 6.7 and Figure 21 in section 8.5.1.
