6.2 Connecting via RS-485
You can control a
VS-808DS
unit via an RS-485 controller, or a Master
Programmable Remote Control system such as the Kramer
RC-3000
.
To connect an
RC-3000
to a
VS-808DS
unit (see Figure 4), connect the
RS-485 terminal block port on the
RC-3000
to the RS-485 port on the
VS-808DS
unit, as follows:
Connect the “A” (+) PIN on the RS-485 rear panel port of the
RC-3000
to the “A” (+) PIN on the RS-485 rear panel port of the
VS-808DS
unit
Connect the “B” (-) PIN on the RS-485 rear panel port of the
RC-3000
to the “B” (-) PIN on the RS-485 rear panel port of the
VS-808DS
unit
If shielded twisted pair cable is used, the shield may be connected to
the “G” (Ground) PIN on one of the units (for example, on the
RC-3000 )
Set the
VS-808DS
unit to a Machine # other than 1, according to
Table 4, and set DIP 4 ON (for RS-485 Line Termination with
120 )
