7. Troubleshooting COM320 Voice Systems
Following are some possible reasons for your COM320 system not working or
not working properly.
7.1 No Communications
Voice Mode — No voice announcements when you call the station
• The COM320 is connected to a digital rather than an analog phone line.
•
The COM320 configuration was changed from its default factory settings
(see Appendix B ,
Updating and Configuring the COM320
(p. B-1)
).
Data Mode — Can’t connect to the station with
LoggerNet
software.
• No commas and/or “9” added to the dial string in LoggerNet to
temporarily put the COM320 into data mode.
•
The “9” is being dialed before the COM320 ‘picks up’ and voices the
announcement (not enough commas).
•
No phone number in the LoggerNet dial string.
•
COM320 is connected to a digital rather than an analog phone line.
• LoggerNet Setup configured for the wrong PC modem.
•
LoggerNet configured for a baud rate the station cannot handle (try 9600).
•
COM320 configuration was changed from its default factory settings
(see Appendix B , Updating and Configuring the COM320
(p. B-1)
).
