E-mail send to: 

Enter a valid e-mail address to receive the

alerts. The "Send Test" option sends a test email to the de-

clared address.

If you require alerts to reach more than one email ad-

dress, you can use the automatic mail forwarding ser-

vice of the email account.

The check boxes "LOG" and "E-MAIL" enable the recording

of each issue in the internal log and for sending alarms re-

spectively.

Audio silence: 

Send an alert when detect a silence that ex-

ceed the limit established in seconds. The value is set us-

ing the right slider.

Overmodulation:

  Sends   an   alert   when   detects   that   the

modulation index exceeds the value set for the alarms.

The value is set using the right slider. This value does not

affect the transmission in any way.

LOW RF power level:

 Send an alert if a drop in the trans-

mitted power is detected. To set the value, press "Set REF"

under   normal   transmission   conditions.   Then   using   the

slider indicate the percentage of power loss for which the

alarm will be activated. This value does not interfere the

transmission in any way.

System START: 

Generates an alarm in case the processor

restarts (for example due to power cut)

System Errors:  

For internal use. Only system events are

logged in the SYSLOG.

3.12.2 Status and Logs

SYSTEM TIME:  

When   the   computer   is   connected   to   a

LAN with Internet access, the computer keeps its time

synchronized using an NTP server.

SYNC FROM PC 

allows synchronization against the clock

of the computer from which it is accessed.

The date and time is only used to record system events

in technical reports.

SYSLOG:

 

It  is an event log  stored  into the  processor’s

memory. Reserved for use by personnel specialized in di-

agnostic tasks and technical support.

3.12 Lite Commander

Lite Commander is a tool for Windows that allows

to program preset changes and switch the mode of

transmission from stereo to mono, according to a

schedule. The mono transmission option is useful

in areas of high congestion in the radio spectrum,

as it extends the coverage area of the radio. This

trick   can   be   used   in   news   programs   or   sports

broadcasts (see "3.8.3 About mono transmission").

Lite   Commanrder   is   free   download   from  

http://

www.solidynepro.com/DW/lite.exe

.   Installation

and  use  instructions   are   installed  with   the   soft-

ware.

The application connects to the processor via IP,

so the computer running Lite Comander must have

access to the IP of the 542APC.
