User Manual

1.14.11 LOG

The ATSC TRANSMITTER is provided with an internal non-volatile memory used to store up to 200 events

in a log. For each event, the date, time and a description are stored in order to help the user in understanding

the sequence of the events and the cause of each alarm.

The log can be viewed locally on the display (see the LOG screen in the Menu Management paragraph)

or by remote. It is possible to clear the log contents only locally.

The events are organized from the last one: the first event in the log is the last that happened. The second is the

previous event compared to the first, and so on.

When the log is full (i.e., 200 events are stored), the new events will replace the older ones, like in a FIFO

(first in/first out) queue.

The type of events that can be stored in the log are:

z Power supply on from mains voltage

z Mute settings (automatic/manual) changed

z Remote/local control changed

z Lockout

z Amplifier voltage alarm

z Amplifier current alarm

z orward power alarm

z Reflected power alarm

z Temperature alarm

z Power supply voltage (-12V, +12V or +5V) alarm

z Modulator no communication, over temperature, general error alarm

z External reference alarm

z ASI/SMPTE inputs related alarms
