DVDO VP50 - Manual (Page 21)

Trigger #1 is powered on when the iscan Vp50 pro is powered on. Trigger #1 is powered
off when the iscan Vp50 pro is put into standby mode. This can be useful for powering on a
display or motorizing a screen or lift.
Trigger #2 can be programmed to be powered on in the ‘output setup’ menu. This action
can be saved as part of a Display Profile. The ‘Lens’ option facilitates use of an anamorphic
lens.
Installer Note: The trigger ports are outputs and are not designed to directly receive a 2-volt
trigger signal from another device, like an amplifier, automation controller or 12-volt power supply.
Care has been taken in the design to ensure that if this was done, no harm should come to the video
processor – but it is strongly recommend that other devices are checked to ensure that the trigger
ports on the Vp50
pro are not being “back-fed”.
Driving Relays: When driving a relay from the 12-volt trigger port(s), we strongly recommend
wiring a clamping diode in parallel to suppress transient spikes when the relay is turned off. some
relays include a clamping diode within the relay package. if it is unknown whether the relay includes
a clamping diode, check the relay coil with an ohmmeter – with the red and black leads touching
the coil pins one way the Ohmmeter should read approximately 0 Ohms resistance (+/-0.4 Ohms),
and with the leads red and black leads switched the ohmmeter should read between 8 ohms and
100 Ohms. If the same value is indicated for both directions (and it’s above 1 Ohm), add a standard
“general diode” like a 1N4001 (can be found at any electronic components store) across the relay
coil pins (see the figure below for connection diagram).

Solid State Loads: The 2-volt triggers do not have a minimum load requirement, which enables
our triggers to drive solid state control devices (MOSFETs and optocouplers) found within newer
devices.
Display Profiles
A Display Profile is a user-defined preset which contains all settings from the output setup menu.
