7.2.2 Monitor
Scanning
MON(2)
is defined as a scanning monitor. It will automatically display cameras as
defined in scan sequence (5). This monitor can be controlled from any keyboard (1 to
32) but can only display cameras that have been assigned to source group (0). Its
associated post text insertion module is located in slot (4) of subrack (1). Again in a
single video subrack system slot (4) in the video output table is not defined as a channel.
7.2.3 Alarm
Monitor
MON(3)
is defined as an alarm monitor. This monitor will display the ALARM MESSAGE
TEXT for all (1 to 50) alarm display groups. The macro sequence for each alarm would
also need to specifically select the required camera to be displayed onto this monitor.
Only keyboards (1) and (5) can control this monitor. The associated post text insertion
module is located in slot(3) of subrack (9). It's assumed that this subrack has been
dedicated for text modules (i.e. no video switching modules).
7.2.4 Auto-blank
Monitor
MON(4)
is defined as an auto-blanking monitor. When left unchanged for (10) seconds
this monitor will automatically select a BLANK video input. This usually would be a black
video source so that the monitor's display would remain dark. The text insertion for this
monitor would also be hidden. Auto-blanking monitors are generally used to remove
non-essential pictures from a control room to minimize distractions. When an alarm
becomes active this monitor would also display the alarm text message on-screen
together with the associated alarm macro selected camera source. The monitor will
NOT automatically blank while an alarm is being displayed.
7.2.5 Monitor
No-Text
MON(5)
is defined as a monitor with no text display. No post text insertion module has
been assigned to this channel. Often scanning monitors are used without any text
display. As the MAXPRO-Net system can be set-up to GRAB a video selection from one
monitor to another a camera can easily be moved onto a MAIN monitor with text
identification. This monitor is defined to be controlled by keyboards ranging (1) through
to (5).
WARNING:
Network trunk channels are also usually
defined without any text insertion.
