Video Delay
Reports the current measured video delay, in ms.
Keylock
Enables the Keylock feature of the unit, which disables front-panel controls.
Valid Settings: Normal, Enable
Default Setting: Normal
This feature should be used only when the DPS-475/575 is being controlled remotely
(for example, from a DPS RC-4000 remote controller). If this option is not activated
(i.e. in Normal mode), then it is possible for a local user to modify the remote-user’s
settings from the front panel. When enabled, this option disables front-panel access,
so all control must be done remotely.
To return to Normal mode, press and hold the Enter and Exit front-panel buttons
simultaneously, or change the Keylock setting from the remote controller.
Function Bypass
Toggles between the master Process and Bypass modes. Process mode is the normal
mode of operation. In Bypass mode, no processing is applied to the Composite In
video signal; it is passed directly to Composite Out. Similarly, in Bypass mode, no
processing is applied to the analog and AES/EBU audio inputs; they are routed
directly to the outputs.
Valid Settings: Process, Bypass
Default Setting: Process
This is equivalent to the user of the Bypass button on the front panel. The light on the
Bypass button flashes while the unit is in master Bypass mode.
Composite In and the analog and AES/EBU audio inputs are also bypassed when the
power to the unit is off.
This option can override the Analog Bypass and AES/EBU bypass options in the
Audio Setup menu. If Function Bypass is enabled (set to Bypass), the analog and
AES/EBU audio inputs are bypassed, regardless of their setting in the Audio Setup
menu.
GPI-1 Function
Selects which function should be triggered when a GPI pulse is received on the GPI-1
connection of the Multi I/O breakout cable.
Valid Settings: Disabled, Freeze, Keyer, Trouble Slide, User 1,
Voice-Over
Default Setting: Disabled
When Disabled, no action will be taken on receipt of a GPI pulse.
When set to Freeze, the currently selected Freeze Mode (see Chapter 5, “Menus:
Video Setup”) will be applied to the incoming video while a GPI signal is present,
similar to pressing the Take button on the front panel of the unit. The live video feed
will be resumed when the GPI trigger is released.
