Automatic Measurement (AVM-510A)

Special Considerations for Alarm Outputs
An alarm output can be set to activate with a preset delay when there is an error in a measurement set.
Both closed captioning and audio missing can also be set to activate the alarm output.
Alarm Output
Pin one on the DC CONTROL/ALARM connector is dedicated to an alarm. When any
automeasuremetn screen or Picture Guard shows an out-of-tolerance condition, this pin goes to
ground (earth) if MASTER ALARM is enabled and after a delay set in MASTER ALARM DELAY.
To configure an alarm:
1.
Press the
Config
button.
2.
Select OTHER and then press the
Entr
button.
3.
Select ALARM SETTINGS and then press the
Entr
button.
4.
Select MASTER ALARM and then press the
Entr
button to turn it ON.
5.
Select MASTER ALARM DELAY and then turn the knob to set a delay of 0 (OFF) or to a delay
setting in minutes.
6.
Press the
Clr Mnu
button to exit.
The alarm output can be set to zero to give an immediate indication of an error for an alarm. The
output can also be set to a delay to initiate other actions after an error has continued for longer than the
delay setting. This action could be to switch to a backup path for routing or a backup video source.
Closed Caption Alarm
The AVM-510A can be set to cause an alarm output if the closed caption signal is missing for a preset
time period.
To configure a closed caption alarm:
1.
Press the
Config
button.
2.
Select OTHER and then press the
Entr
button.
3.
Select ALARM SETTINGS and then press the
Entr
button.
4.
Select CC ALARM DELAY and then turn the knob to set a delay of 0 (OFF) or to a delay setting to
enable the alarm.
5.
Press the
Clr Mnu
to exit.
The alarm output is off when the delay is set to zero. The output can also be set to a delay to initiate
the alarm when the error has continued for longer than the delay setting.
Audio Alarm
Audio limits can be set to generate reports or to activate an alarm if audio levels are above or below set
limits for longer than a set time. Refer to the section on “Audio Limit Reporting,” in Chapter 8, for
more information.
