To connect an RS-485 connector on one
VS-3232A
unit to an RS-485
connector on one or more video switchers (from the series of 32x32 or 16x16
matrix switchers), as
Figure 17
illustrates:
1. Connect the “A” PIN on the first
VS-3232A
unit to the “A” PIN on the
VS-3232Vxl
unit and to all the other video units.
2. Connect the “B” PIN on the first
VS-3232A
unit to the “B” PIN on the
VS-3232Vxl
unit and to all the other video units.
3. If shielded twisted pair cable is used, the shield may be connected to the “G”
(Ground) PIN
If necessary (for a video-audio combination only), connect the SYNC pins
together. For details about how to configure the vertical sync (if required),
refer to
Section 7.7

Figure 18 illustrates the RS-485 line that connects:
•
Between the
VS-3232Vxl
and
VS-3232A
unit
•
To the PC via a Kramer TOOLS
VP-43xl Interface Converter
(connect the
9-pin D-sub COM port of the PC to the RS-232 IN 9-pin D-sub F port on
the
VP-43xl
and then connect the RS-485 port on the
VP-43xl
to the
RS-485 ports on the switcher units)
