COM310 Voice Communications Modem
In LoggerNet a comma represents a 1 second delay. You may need to adjust
the number of commas so that the “9” occurs during the voice announcement,
depending upon the length of time required to establish the connection with the
modem.
For information on creating an Edlog datalogger program and downloading it
to the COM310 station, refer to the Basic Tutorial in LoggerTalk help.
