Alarm Triggers - Serial

Serial alarms are alarm contacts routed to a RS232 port on the MegaPower 48+ patch panel via an AD2096A Alarm

Interface Unit (AIU). Each connected AD2096A unit can be connected to 48 alarm inputs. A maximum of 512 serial

alarm inputs can be connected.

The Serial Alarm Setup screen is used to create an alarm response for each connected serial alarm. To display this

screen, expand the Alarm Triggers node (inside the Alarm Configuration node) on the left-hand side of the display

area and then click the Serial node.

For each serial alarm contact, complete the fields described in the table on page 35.

Video loss alarms are triggered by the loss of the synchronisation signal from any video input connected to the MegaPower

48+ patch panel. There can be a video loss alarm for every video input, whether it is connected to the primary matrix or

to a secondary unit. This means there is a maximum of 288 video loss alarms.

To activate video loss alarms, it is necessary to enable video loss detection in the Options screen (see page 16). Video

loss detection can then be enabled for individual video inputs in the Titles/Pseudos screen (see page 17).

The Video Loss Alarm Setup screen is used to create an alarm response for each video loss alarm. To display this

screen, expand the Alarm Triggers node (inside the Alarm Configuration node) on the left-hand side of the display

area and then click the Video Loss node.

In this screen, video loss alarms are only listed for the video inputs that have had video loss detection enabled (see

page 17). The video loss alarms are listed by the port reference and pseudo number of the video input. In the port

reference, the first character refers to the matrix to which the video input is connected (X = primary unit, A-F = secondary

unit) and the second and third characters are the video input port number on that matrix (1-48).

For each video loss alarm, complete the fields described in the table on page 35.
