KRAMER: SIMPLE CREATIVE TECHNOLOGY
Controlling the VS-44HC

7.2 Controlling via RS-485
You can control up to 15
VS-44HC
units via an RS-485 controller, for
example, a PC (equipped with an RS-485 interface) or a Master
Programmable Remote Control system such as the Kramer
RC-3000
1
.
To connect an
RC-3000
to a
VS-44HC
unit (see Figure 7), connect the
RS-485 terminal block port on the
RC-3000
to the RS-485 port on the
VS-44HC
unit, as follows:
1. 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-44HC
unit
2. 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-44HC
unit
3. 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
)
To cascade up to 15 individual
VS-44HC
units, via RS-485, as illustrated in
Figure 7, do the following:
1. Connect the component video sources and acceptors, as well as the
appropriate digital audio sources and acceptors, as section 6.1 describes.
2. Connect the RS-485 terminal block port on the first
VS-44HC
unit to the
RS-485 port on the second
VS-44HC
unit and so on, connecting all the
RS-485 ports.
7.2.1
Set the Dipswitches
Set the dipswitches, as section 6.3 describes:
Assign a unique machine #
2
(from 1 to 15) for each
VS-44HC
unit,
according to Table 5
Set DIP 8 ON on the
VS-44HC
unit located at the end of the line
(terminating the RS-485 line at 120 ).
Set DIP 8 OFF on the other
VS-44HC
units
Set DIP 5 OFF on all
VS-44HC
units
Set DIP 6 and DIP 7 according to the IN 2 digital audio input signal
(Table 6)
