1
Connector
Connect remote contact-closure switches to the REMOTE terminal block
connector, for example to a single XGA/Audio switcher such as the
VP-81xl
,
as Figure 12 describes. A remote unit can consist of a mechanical switcher
2
with a common wire for ground
3
.
Figure 12: Connecting a Remote Mechanical Switcher Unit to the VP-81xl
1 The REMOTE terminal block connector has 8 pins (plus the G pin) on the VP-81xl, 16 pins on the VP-161xl, and 32 pins
on the VP-321xl
2 The remote unit can have up to 8 buttons for the VP-81xl, corresponding to the front panel INPUT SELECTOR buttons.
Similarly, 16 buttons for the VP-161xl, and 32 buttons for the VP-321xl
3 Providing control over a distance up to hundreds of meters
