COM310 Voice Communications Modem
5.2.2.1 Data Callback Instructions
The following instructions are used to program a data callback.
DialSequence/EndDialSequence
The DialSequence/EndDialSequence instructions are used to define the code
necessary to route packets to a PakBus datalogger. Any time an instruction
(SendVariables) in the main program requires that communication be made
with the remote PakBus device identified by the PakBusAddr parameter
(LoggerNet server with PakBus address = 4094), the DialSequence code for
that datalogger will be executed.
DialModem
The DialModem instruction is used to send a modem dial string out one of the
datalogger's ports. DialModem can be used within DialSequence /
EndDialSequence to specify a communication route to be used for a PakBus
device.
The ResponseString is used to specify the response code expected back from
the modem when a connection is made. When a null string is entered ("") the
default is "1"+ CHR(13).
SendVariables
The SendVariables instruction is used to send value(s) from a variable or
variable array to a data table in a destination PakBus device.
In the example data callback program, the variable “dummy” is sent to
LoggerNet as a signal for LoggerNet to begin collection of the datalogger.
5.3 Edlog Dataloggers and LoggerTalk
To program a voice capable mixed-array or PakBus Edlog datalogger for voice
communications, voice codes are appended to the datalogger’s *.dld file.
LoggerTalk software is shipped with the COM310 to accomplish this.
LoggerTalk requires a PC running Windows NT/98/ME/2000/XP and
equipped with a CD-ROM drive for installation.
5.3.1 Install
To install LoggerTalk, insert the auto-run CD into the drive and follow
directions to complete the installation.
5.3.2 Helps and Tutorials
LoggerTalk information is available in its extensive Help system. You can
access Help by pressing the F1 key, by selecting Help from the main window,
or by clicking the Help button.
Two tutorials are included in LoggerTalk Help. The first is a basic tutorial on
creating voice strings, sending the LoggerTalk edited *.dld program to the
datalogger, and navigating through the voice modem menus. The second
