You can use any existing e-mail account. But most stations find it more efficient to es-
tablish an account specifically for PDM.
Mail server address
: Enter a valid SMTP server address, such as the one where
you normally send outgoing e-mail. A typical address may look like
smtp.kpdm.com
. The default mail server port is 25. If your mail server is on a
port other than 25, specify it by typing a colon and the port number; for example,
smtp.kpdm.com:587
Mail server username
: Enter a valid e-mail account user name,
without the
@
sign
and domain name
. A typical entry may look like
gsteadman
or
PDMStudio1
.
Mail server password
: Enter the password associated with that user name. This
password is required by your SMTP server.
Sender
: Enter the complete email address for that user name (for example,
. Even though PDM can’t receive replies at that address,
mail servers use this data to verify messages are legitimate.
PD-Alert context
sets an amount of additional audio, from before and after each
Dump event, which gets saved at the start and end of PDM’s log files. Choose
enough additional time to help you identify a Dump event’s context. Usually five
or six seconds is plenty, but if you are running very long program delays, set
con-
text
to the maximum value.
PD-Alert (attached audio) e-mails
: Enter the e-mail addresses of people or servers
who should receive PD-Alerts
with attached audio files
. (Use the
PD-Alert (text)
field, below, for users who don’t want to receive audio files. Those users can still
access audio files from within PDM.)
•
If you want to enter more than one “attached audio” recipient, separate each
address with a space.
Attached audio file format
: Use this drop-down menu to choose audio quality
and data compression for e-mailed log files. Our compression is playable on
most modern computers, smartphones, and other portable data devices.
•
Uncompressed WAV
: highest quality but also the largest files; may be too large
to handle conveniently on mobile devices.
•
High Quality MP3
: Roughly equivalent to FM Radio, sent at about 160 Kbps.
•
Voice Quality MP3
: Roughly equivalent to AM Radio, at 40 Kbps.
