Connecting an XGA / Audio Switcher

6.4.2 Setting the MACHINE ADDRESS #
For certain applications, you may need more than 8 inputs 1 . Cascading the
inputs of VP-81xl/VP-161xl/VP-321xl units enables you to expand the
number of inputs by looping up to seven units to form a combined XGA /
Audio Switcher with up to 218 inputs. Be aware that:
Cascading VP-81xl/VP-161xl/VP-321xl units can cause XGA signal
quality degradation
Choosing the quantity of
VP-81xl/VP-161xl/VP-321xl units to cascade
depends on your particular XGA signal quality requirements
The technical specifications contained in Table 10 are guaranteed for
stand-alone units only
To cascade up to seven identical 2 units, that is, seven VP-81xl units, or seven
VP-161xl units, or seven VP-321xl units:
Set the same MACHINE # on each unit, according to Table 8
Set the MACHINE ADDRESS # and the eighth dipswitch (last in
daisy-chain) on each unit that is included in a set, according to Table 9
1 For example, if you want to connect 50 VGA/XGA audio sources and then be able to switch any one of them at any time
2 Only the same types of units (for example, seven VP-161xl units) can be cascaded – you cannot mix the various types (a
cascade cannot include say, four VP-81xl units, and three VP-161xl units)
