7.1 Cascading Units in an Input Expansion Configuration
You can cascade up to eight interconnected
VS-402XL
/
VS-602XL
units to
form an input expansion configuration. For example, to create a 48 x 2
switcher, with 48 inputs and two outputs, connect as
Figure 11
illustrates.
To cascade
VS-402XL
/
VS-602XL
units to expand the number of inputs,
connect as follows:
1. Connect the composite video sources and acceptors, as well as the appropriate
audio sources and acceptors, as section 6 describes.
2. Connect the RS-232 port on the first
VS-402XL
/
VS-602XL
unit
(MACHINE # 1) to the PC using the Null-modem adapter provided with the
machine (recommended), as section
6.1
describes.
3. Connect the RS-485 terminal block port on the first
VS-402XL
/
VS-602XL
unit
to the RS-485 port on the second
VS-402XL
/
VS-602XL
unit and so on,
connecting all the RS-485 ports, as
Figure 11
illustrates.
1 You can interconnect VS-402XL units with VS-602XL units, and you are not limited to cascading VS-602XL units with
VS-602XL units. For example, for a 10x2 vertical interval video-audio matrix switcher, interconnect a VS-402XL unit with a
VS-602XL unit
