COM320 Voice Communications Modem
11
The COM320’s communication port is designed to function with
a Campbell Scientific CS I/O port. This is not an RS-232 port.
See Appendix C , CS I/O 9 Pin Serial Port
(p. C-1)
, for the CS I/O
port description.
4.2 Surge Suppressor
If the phone company does not provide surge protection at the datalogger site,
you will need to install some. CSI offers surge protectors in two forms:
pn 6362 is a surge protector with environmental enclosure mounting hardware
and pn 4330 is the surge protector with no mounting hardware (see Section 6.5 ,
Connecting to a Surge Protector
(p. 21)
).
4.3 Voice Capable Dataloggers
The COM320 is compatible with the CR6, CR800, CR850, CR1000, and
CR3000 dataloggers. They must have an operating system ≥ the following:
CR800/CR850 version 7, CR1000 version 16, and CR3000 version 9. It is not
compatible with CR200-series, CR5000, CR7, CR9000X, or any retired
dataloggers.
The COM320 supports such functions as program send, data collection, clock
check, voice callback, voice callin, and data callback.
The modem also supports concurrent communications. Dataloggers with
multiple peripherals (COM320, RF450, RF401, MD485, NL115, CR1000KD,
and SC32B) can communicate simultaneously via those peripherals.
4.4 Telephone
A touch-tone phone is normally used to call the COM320 modem. A rotary
phone will work if the programmed voice announcements do not require you to
navigate through the COM320’s menu system.
The COM320 must connect to an analog phone line. Some PBX
phone lines are digital and don’t interface to an analog modem
such as the COM320. Of course, any phone may be used to call
in or receive callbacks from the COM320. A touch-tone phone is
necessary for input.
5. Datalogger Voice Programming
The voice code for the datalogger is integrated with the main program. It is
probably advantageous to complete and debug your custom voice program
before adding the measurement code. The example voice callback/callin
program in Section 3.1 ,
CR1000 Example Program
(p. 6)
, can provide a starting
point for your program.
5.1 Features
The voice instructions listed in Section 5.2 , Voice Instructions
(p. 13)
, are
combined with standard CRBasic instructions to create the code needed for
