Ignore Preroll Commands
A minimum 4-frame pre-roll is required to allow the server time to respond to serial
commands. See the documentation for your controller or automation to find out how to set the
preroll value. Due to various ways preroll commands are implemented in different systems, it may
be sufficient to check only this box. A setting of 4 frames in the automation controller will then
work correctly.
This option is very seldom used; it allows preroll commands to be ignored and assumes that
the operational preroll is 4 frames. Do not check this unless you experience problems with frame
accuracy on recordings and playback transitions. Start with a setting of 4 frames on the automation
system and adjust until you achieve proper timing.
Auto E-E
Toggles Auto E-E mode (input monitor) on/off.
Assigned Serial Ports
VDCP protocol provides for altering the mapping of Serial Port to Video Channel via control
commands. Checking this option will lock the Serial Port to Video Channel ordering.
• When checked, any command received on a particular serial port will be used to control
the like numbered video channel. This means that automation systems that use fixed or
limited VDCP ID numbers can use any output to control any channel of the server.
• With this option checked, there is no requirement for a Port Open command to allow the
automation to control the channel. With some systems, this can negate the requirement to
restart the automation system when bringing the server online.
• Do not check this option when using controllers that communicate with all channels over a
single serial port.
Communication Port Parameters
The serial data transfer parameters for the server are fixed and cannot be changed. These
characteristics are common to all automation controllers:
