You can connect any of the following:
A VS-1616SDIunit with any matrix switcher that forms part of the series of 16x16 matrix switchers, using a Null-modem adapter (see section 6 .4.1.1) or without using a Null-modem adapter (see section 6 .4.1.2)
The PC’s DB9 COM port to a VS-1616SDIunit with a Null- modem adapter (see section 6 .4.1.3) or without a Null-modem adapter (see section 6 .4.1.4)
The PC’s DB25 COM port to a VS-1616SDIunit without a Null- modem adapter (see section 6 .4.1.5)
6.4.1.1Connecting with a Null-modem Adapter
To connect a VS-1616SDIunit with any matrix switcher that forms part of the series of 16x16 matrix switchers, using a Null-modem adapter provided with the machine (default):
1.Connect a flat cable1 between the RS-232 OUT DB9 port on the VS-1616SDIunit and the Null-modem adapter that attaches to the RS-232 IN DB9 port on the other 16x16 matrix switcher.
2.On the other 16x16 matrix switcher, set DIP 7 OFF (enabling Null-modem adapter use).
6.4.1.2Connecting without a Null-modem Adapter
To connect a VS-1616SDIunit with any matrix switcher that forms part of the series of 16x16 matrix switchers, without using a Null-modem adapter:
1.Connect a flat cable1 between the RS-232 OUT DB9 port on the VS-1616SDIunit and the RS-232 IN DB9 port on the other 16x16 matrix switcher.
2.On the other 16x16 matrix switcher, set DIP 7 ON (disabling Null-modem adapter use2).
6.4.1.3Connecting to a DB9 COM Port with a Null-modem Adapter
To connect the PC’s DB9 COM port to a VS-1616SDIunit, using a Null- modem adapter:
1.Connect a flat cable1 between the PC’s DB9 COM port and the Null- modem adapter that attaches to the RS-232 IN DB9 port on the VS-1616SDIunit.
