COM310 Voice Communications Modem
5.3.6 Voice Callback
LoggerTalk can program a voice callback when associated with a *.dld file that
includes a P97 with Parameter 1 = “31” for mixed-array dataloggers or “39”
for PakBus dataloggers (see Section 5.1.1.2).
LoggerTalk allows you to input multiple phone numbers to increase the
probability that the alarm message will get through. If the first phone is not
‘picked up’ then the second number is dialed. If the second number is not
picked up then the third number is dialed, etc.
There is a LoggerTalk Help tutorial to guide you through setting up datalogger
initiated callback.
5.3.7 View and Remove Voice Code
Although the voice code LoggerTalk adds to a *.dld file is not visible in Edlog,
you can open a *.dld file in a text editor such as Notepad
®
and view voice
codes appended to the *.dld file. The text editor is only recommended for
viewing the file (not editing it). See Appendix F of this manual for a guide to
interpreting the voice codes.
To remove voice code from a *.dld file, open it in LoggerTalk, remove all
voice strings, and click on “Save Edits.”
5.4 LoggerNet
By default the COM310 operates in voice mode, enabling you to call a station
and hear voice announcements or enabling the station to do a callback to you
and announce an alarm. The COM310 also has the ability to function in data
mode. In data mode, the COM310 supports data collection and other standard
LoggerNet functions.
You can set up LoggerNet to call and perform scheduled collections of storage
data or you can program the datalogger to do callbacks under the conditions
you specify at which time LoggerNet will collect the data.
For scheduled (or manual) collection you change the COM310 to data mode
by including six commas and a “9” in LoggerNet’s dial script in the Setup
Screen’s Hardware Tab for PhoneRemote.
For callback collection, the CR1000’s DialSequence instruction changes the
COM310 from default voice mode to data mode. An Edlog datalogger’s
program P97 with Callback ID puts the COM310 in data mode.
The commas create a delay so that the “9” is received by the COM310 during
the voice announcement. When the COM310 detects the “9” it disables voice
communications and enables data mode for the remainder of that connection.
For example, in LoggerNet, if the phone number is "555-4321" then in order to
call the COM310 and enable data mode the dial script becomes:
"555-4321,,,,,,9"
