COM320 Voice Communications Modem
1. Introduction
The COM320 is a voice-synthesized modem that supports the CR800, CR850,
CR1000, and CR3000 dataloggers. The COM320 allows the datalogger to
announce over the telephone specific variable data, present state of flags and/or
control ports, and the ability to toggle flags and/or control ports. Along with
announcing information over the phone, the datalogger can also be
programmed to call specific phone numbers with different messages when
specific conditions are met.
Although the primary function of the COM320 is voice communications, the
modem is also capable of data communications. In data mode the COM320
supports standard datalogger functions including program send, data
collection, and data callback.
This manual provides information regarding COM320 specifications,
installation, and operation. Quick Start (Section 3) presents an example
CR1000 voice callback/callin program with descriptions of the code.
Section 6.3 explains how to make a good earth ground connection to maximize
protection of the COM320 against lightning and electro-static discharge.

3. Quick Start
NOTE
This section presents Basic_Voice_2.cr1 an example voice callback/callin
program written to demonstrate functions of the COM320. It can serve as a
starting point from which to build an application program. Test the autodisconnect capability as you customize the voice code and merge your
measurement sections with the voice code.
To demo the example program, obtain the following items or their equivalent:
1) COM320 (COM320_OS.03 or later OS)
2) SC12 Cable
3) CR1000 datalogger
4) 3 inches of thermocouple wire
5) PS100 Power Supply
6) Phone modem for your PC
7) LED in series with 1000 Ohm resistor
8) Analog phone line
The COM320 cannot interface with office digital phone lines.
Connect the COM320 to analog phone lines only, such as a fax
line.
You will also need:
2
1) Windows compatible PC with available COM port
2) LoggerNet 3.4.1 or later installed on PC.
The datalogger’s voice code is created along with the measurement program
using the CRBasic editor. It is recommended to finish and debug the voice
portion of the program first, and then add the measurement code.
The example CR1000 voice callback/callin program that follows supports the
following functions:
• Voice callin
• Voice callback
• Auto-disconnect
• Auto redial
• Alarm reset
The following steps show how to build a station to demo the example voice
callback/callin program. The voice station can further serve to test/debug a
custom voice program and merge it with an application program.
Step 1 – LoggerNet Setup
1) In LoggerNet Setup create the following device map
COM320 Voice Communications Modem
2) Configure ComPort and PhoneBase for your PC’s phone modem.
3) Configure PhoneRemote to include the COM320’s analog phone number
followed by six commas and a 9.
4) Click on CR1000phone (renamed) and verify that the PakBus Address is 1.
Step 2 – Hardware Setup
1) Start with a CR1000 having factory settings. If unsure of settings, close
LoggerNet, connect SC12 cable from PC ComPort to CR1000 RS-232
port, run Device Configuration Utility, set Serial Port to match the PC
ComPort, Connect and click on the Factory Defaults button, Apply
settings and Disconnect.
2) Turn off PS100 if it isn’t already.
3) Connect CR1000 to PS100 (turned off).
4) Connect SC12 cable from COM320 to CR1000 CS I/O port.
5) Connect analog phone line to COM320.
6) Turn on PS100.
7) Connect prepared TC to CR1000’s DIFF 7 analog input.
8) Connect LED with 1000 Ohm resistor connected to anode lead from C1 to
G (resister to C1).

COM320 Voice Communications Modem
Step 3 – Send BASIC_VOICE_2.CR1 to CR1000
1) Download BASIC_VOICE_2.CR1 from CSI web site under Support,
Downloads, Program Examples, COM310 Examples to a folder on your
hard drive.
2) From LoggerNet Toolbar run CRBasic editor and open
BASIC_VOICE_2.CR1.
3) Change PHONE1 (a constant in SlowSequence near bottom of program)
to your office phone number to be used for callback and Save and
Compile the change.
4) You can change PHONE2, etc. to nearby phone numbers for testing or
comment out those lines of code. NUMPHONES should equal the number
of active phone numbers.
5) If the TC at DIFF 7 isn’t Type T, change the program to match your TC
type and Compile and Save.
6) Connect to CR1000phone and in Connect Screen, File Control send
BASIC_VOICE_2.CR1 to CR1000phone.
7) Close File Control and Disconnect from CR1000phone.
Step 4 – Callin
Step 5 – Callback
8) Your CR1000 voice station is ready to demo.
1) Using a touch-tone phone, dial the number of the analog phone line
connected to the COM320.
2) You should hear a ring or two, some faint clicking and then the voice
announcements:
CURRENT STATION DATA
PRESS ONE TO HEAR THE BATTERY VOLTAGE
PRESS TWO TO HEAR THE DATALOGGER TEMPERATURE
PRESS THREE TO HEAR THE T C TEMPERATURE
PRESS STAR TO DISCONNECT
3) Pressing 1, 2, 3, or * should produce the result indicated.
1) Grip the end of the thermocouple to raise its temperature above 85F
setting an alarm condition.
2) In a few seconds you should be able to detect the dial tones as a voice
callback proceeds. The first phone number in the program should ring.
Picking up the phone you should hear:
PRESS POUND TO RESET ALARM, PRESS STAR TO DISCONNECT
Pressing the # key you should hear:
C R ONE THOUSAND STATION
PRESS ONE TO HEAR A SENSOR VALUE
4
COM320 Voice Communications Modem
PRESS TWO TO HEAR OR TOGGLE PORT
PRESS THREE TO HEAR OR TOGGLE FLAG
PRESS STAR TO DISCONNECT
3) Navigate around in the menus to learn the program’s capabilities:
a) Press 2 to access the Ports Menu.
b) Press 1 to read the logic state of Control Port 1.
c) Press # to toggle the logic state of Control Port 1 (C1’s LED should
turn on).
d) Press # again (C1’s LED should turn off).
e) Press * to return to “C R ONE THOUSAND STATION” menu.
f) Press * to hang up.
4) Try hanging up the phone without pressing * (disorderly exit) and see if
the modem automatically hangs up after a few seconds.
5) As you press the keys to navigate around in the menus you will find that
occasionally you get an unexpected response. Phone connections are
susceptible to noise pickup and signal attenuation. Depending on your
particular phone equipment and the phone lines and equipment between
you and the voice station, you may at times experience some of the
following:
a) You press * and the voice station hangs up but doesn’t say,
“Goodbye.”
b) A voice callback rings your phone but you pick up to silence
Certain phones are more of a problem due to low signal levels or
switch bounce.
6) Helpful hints for pressing phone keys to control a voice station
a) Press a key firmly (but not too long).
b) Allow a second between key presses.
c) Press the same key again if getting an incorrect response.
d) If no response, try pressing the same key again or press the # key to
recover.
e) If unresponsive, try rapidly pressing a series of five * keys to
disconnect station.
f) Worst case, hang up and allow 6 minutes for the voice station to reset
itself.
Following is the text of the BASIC_VOICE_2.CR1 example voice
callback/callin program employing VoiceSetup( ). The program should be
available for download on CSI’s website under Support/Downloads/Program
Examples. Following the program is a description of its main sections.

Example Program Description
NOTE
VoiceSetup( )
Bold text indicates a CRBasic instruction. Italic text indicates a
subroutine.
Basic_Voice_2.cr1 has five main sections:
1. VoiceSetup( ) - handles auto-disconnect.
2. Voice Beg / EndVoice - routes execution to callin or callout subroutines.
3. CallInVoice Subroutine - executes when VoiceBeg detects a callin
4. CallOutVoice Subroutine - executes when VoiceBeg detects a dial-up. It
looks for a pound (#) key to reset “alarm” variable to false.
5. SlowSequence - continually looks for the “alarm” variable to be true,
which if it is, it dials a list of phone numbers until “alarm” is no longer
true. It signals Voice Beg when a callout dial-up is in progress.
The VoiceSetup instruction is used to control the hang up of the COM320
voice modem. It controls which key is used to exit a subroutine and which is
used to continue to the next VoiceKey instruction. It also determines how long
the COM320 can be ‘off hook’ before the datalogger automatically hangs it up
(auto-disconnect). And it controls whether or not the modem hangs up after a
VoiceKey instruction timeout. The “Callout” parameter indicates that the
modem has received a ‘call in’ or has dialed a ‘call out.‘
10
COM320 Voice Communications Modem
WARNING
Voice Beg / EndVoice
CallInVoice Subroutine
CallOutVoice Subroutine
The VoiceSetup SecsOnLine setting is important as it
hangs up (auto-disconnects) the modem in case
someone hangs up the phone or leaves the phone offhook without pressing star keys for an orderly “goodbye” disconnect. Test the entire program in this regard
before deployment to avoid possible lengthy off-hook
states disallowing incoming calls, running up a phone
bill and draining the station power supply.
At call in, the VoiceBeg / EndVoice instruction pair enclose the code that is
executed when the datalogger detects a ring from the COM320.
This subroutine contains the code pointed to by VoiceBeg / EndVoice that is
to execute after a call in occurs. It consists mainly of VoiceSpeak menu
announcements followed by a VoiceKey instruction prompting caller input and
a Select Case statement choosing the program’s responses to various caller key
presses.
The CallOutVoice subroutine contains the code that is to execute when
VoiceBeg / EndVoice detects that a call out phone number has been dialed. It
prompts a responding party to press the # key after which it announces the
menu selections to hear: battery voltage, panel temperature, or thermocouple
temperature (SubKey1); datalogger port status of C1 - C8 (SubKey2); or
datalogger flag status of F(1) - F(8) (SubKey3). The state of the ports and flags
can be toggled as well as heard.
SlowSequence
Contains code that continually executes looking for the Diff 7 thermocouple to
exceed 85°F in which case the variable “alarm” is set to “True” and a call out
(callback) is initiated. It dials the first phone number on the list. If no answer,
after 20 seconds the second number is dialed. The list of phone numbers is
dialed repeatedly until someone picks up and presses the # key (monitored by
the CallOutVoice subroutine) which resets “alarm” to False and allows the
responding party to proceed into the CallOutVoice menus.
4. System Components
4.1 COM320 Modem
Connecting a COM320 voice modem to a datalogger provides all COM220
supported functions plus the following:
• Voice retrieval of data (user or datalogger initiated)
• Reading/Toggling of datalogger control ports
• Reading/Toggling of program Flags
11
COM320 Voice Communications Modem
The COM320 ships with an SC12 cable (9-pin to 9-pin) for connecting
between the modem CS I/O port and datalogger CS I/O port.
NOTE
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 E 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. Item #
6362 is a surge protector with environmental enclosure mounting hardware.
Item # 4330 is the surge protector with no mounting hardware (see Section
6.5).
4.3 Voice Capable Dataloggers
The COM320 is compatible only with the CR800, CR850, CR1000, and
CR3000 dataloggers. They must have an operating system equal to, or greater
than, the following: CR800/CR850 version 7, CR1000 version 16 and CR3000
version 9. It is not compatible with the CR200-series, CR5000, CR7,
CR9000X, or any of our retired dataloggers.
The COM320 supports such functions as program send, data collection, clock
check, voice callback, voice calling, 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.
NOTE
The COM320 must connect to an analog phone line. Some
office environment 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 to 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 write your custom voice program and debug it
before adding the measurement part. The example voice callback/callin
program in Quick Start can provide a starting point for your program.
12
5.1 Features
5.1.1 Callback
5.1.1.1 Data Callback
COM320 Voice Communications Modem
The voice instructions listed in 5.2 are combined with standard CRBasic
instructions to create the code needed for telephone answering, dialing, voicing
word strings, voicing data, receiving key presses from the remote phone, and
acting upon those key presses.
Callback is the ability of a datalogger/COM320 station to initiate a phone call
‘back’ to a PC running LoggerNet (data mode) or to a telephone (voice mode).
Data callback and voice callback code can be included in the same program.
See example CR1000 voice callback/callin program for details.
A station can be programmed to do a data callback in the event specified
conditions are met to a PC (with phone modem) running LoggerNet. Data
callback causes LoggerNet to collect datalogger data marked for collection.
You must enable Callback (sometimes in two places) in LoggerNet Setup.
The datalogger program uses a SendVariables instruction to effect a data
callback (see example data callback program below). No callback ID is used.
5.1.1.2 Voice Callback
The COM320 gives you the ability to do voice callbacks. You can program a
station to call one or more telephone numbers and announce an alarm message
when conditions you specify are met. You can input multiple phone numbers
to increase the probability that someone will receive the message.
Dataloggers accomplish voice callback with a combination of VoiceSetup,
VoiceKey, VoiceSpeak, and DialVoice instructions (see example voice
callback/callin program).
5.1.2 Voice Callin
Callin is the ability of a station to accept a phone call and announce words and
data and, possibly, accept menu key presses. All voice capable dataloggers
support callin. The dataloggers require that callin code be added to the
program (see example voice callback/callin program in Quick Start).
5.1.3 Voice Storage Data
The COM320 recites data stored in variables. You can also recite data stored
in tables by setting a variable equal to Tablename.Fieldname (fieldname index,
records back). You can then get a specific field from the data table (for more
information see CR1000 section Program Access to Data Tables).
The VoiceSpeak code might look like this:
TC_1 = Public.AirTemp(1,1)
VoiceSpeak ("THE AIR TEMPERATURE WAS" + TC_1 + "DEGREES", 0)
13
COM320 Voice Communications Modem
5.2 Voice Instructions
The Quick Start example voice callback/callin program
“BASIC_VOICE_2.CR1” provides a starting point from which to build the
features you want.
Patterned after the example program in Quick Start, voice instructions can be
combined in a variety of ways to provide phone access to datalogger data and
for control of datalogger flags/output control ports.
5.2.1 VoiceBeg / EndVoice
This instruction pair contains the code executed when the datalogger detects a
RING signal from the COM320 (a call in). It is placed in the declarations
portion of the program before the BeginProg instruction. The EndVoice
instruction hangs up the modem. So, VoiceHangup is not required unless you
want to hang up the modem under certain condition(s) prior to the execution of
the EndVoice instruction.
The VoiceKey instruction is also used to add a delay before the EndVoice
instruction is executed so that the datalogger will not end the VoiceSpeak
command before the spoken message is completed.
5.2.2 VoiceSpeak
5.2.3 VoiceKey
The VoiceSpeak() instruction defines the string spoken by the voice modem.
The string is comprised of concatenated words and string variables. To ensure
coded words are valid, CRBasic checks them against the voice.txt file, which
mirrors the word list internal to the COM320. Voice.txt resides in the
“C:\CAMPBELLSCI\LIB\COMPILER” folder. To use VoiceSpeak(), select it
from the instruction list in CRBasic Editor and click Insert. CRBasic Editor
brings up a list of available words. Words can be inserted in any order. Words
are enclosed with quotes and variables are concatenated with words using a
plus sign. For example, "50MS THE BATTERY VOLTAGE IS" + Value(1) +
"VOLTS" is a valid string. The word “50MS” inserts a 50 millisecond pause
during the announcement. 50MS can be inserted multiple times in series.
The VoiceKey instruction is used to add a delay before the EndVoice
instruction is executed so that the datalogger does not end the VoiceSpeak
command before the announcement is finished.
The VoiceKey instruction’s timeout parameter is used to add a delay (in 0.01
seconds) before EndVoice or Loop is executed. Multiple VoiceKey
instructions placed before an EndVoice or Loop instruction increase the delay.
The VoiceKey timeout provides silent time for a user to respond to the
announced menu; however, the user can respond by pressing a key in the
middle of an announcement.
14
If doing concurrent communications (via multiple communication peripherals)
with your datalogger it is recommended that the VoiceKey timeout be
extended to over 5 seconds.
VoiceSetup’s UseTimeout parameter determines whether or not the datalogger
will hang up the COM320 after the timeout in the VoiceKey instruction
expires.
5.2.4 VoiceNumber
5.2.5 DialVoice
5.2.6 VoiceHangup
COM320 Voice Communications Modem
The VoiceNumber instruction returns the accumulated touch tone digits that
are received prior to the receipt of a # or * key. The example voice
callback/callin program uses no VoiceNumber instructions; however, this
instruction may be useful for phone transfer of long numbers such as for
passwords, etc.
The DialVoice instruction is used to define the dialing string for a COM320
voice modem, usually for voice callback. If the DialVoice instruction is set
equal to a variable, a True will be returned if the communication attempt was
successful or a False will be returned if it failed. VoiceHangup is used after a
communication attempt to hang up the voice modem. The DialString is the
telephone number and any other codes used to dial the modem. The DialString
can be a variable. A comma in the DialString inserts a 2 second pause.
The VoiceHangup instruction is used most often with the DialVoice instruction
to hang up the modem after communication. The VoiceHangup instruction is
not needed if the voice commands are enclosed within the VoiceBeg /
EndVoice instructions.
5.2.7 VoiceSetup
The VoiceSetup instruction controls the hang up of the COM320 voice
modem. It also allows you to specify certain handset key functions.
The HangUpKey parameter specifies the key that, when pressed, will
disconnect the COM320.
The ExitSubKey parameter specifies the key that will exit a subroutine if the
datalogger is running one. The ContinueKey parameter specifies the key that
will begin announcing the next VoiceSpeak phrase.
The SecsOnLine parameter specifies the maximum number of seconds that the
COM320 will be off-hook before it is hung up by the datalogger.
The UseTimeout parameter determines whether or not the datalogger will hang
up the COM320 after the timeout in the VoiceKey instruction expires. If this
parameter is set to True, the timeout will be used. If False, the timeout will not
be used.
The CallOut parameter is a Boolean value that indicates the COM320 mode.
When the value returned in this parameter is True the datalogger has called
out. When the value is False the datalogger has received an incoming call.
If the same ASCII character is used for HangUpKey and ExitSubKey, the
datalogger will exit a subroutine if it is in one, otherwise, it will hang up the
COM320. When the specified ContinueKey is pressed, the COM320 will skip
the current VoiceSpeak string and move to the next one. If any other key is
pressed, the COM320 will skip to the next group of VoiceSpeak instructions.
15
COM320 Voice Communications Modem
5.2.8 VoicePhrases
The VoicePhrases instruction is used to provide a list of phrases for a
VoiceSpeak instruction. This instruction allows the VoiceSpeak instruction to
output a string from a list of several strings, depending upon some condition in
the program.
5.3 Data Callback
The COM320 can be put into data mode to accomplish data callback,
instructing LoggerNet to do a collection of datalogger data.
5.3.1 Example Data Callback Program
The following program (downloadable from CSI web site under
Support/Download/Program Examples) does data callbacks to the phone
number associated with the DialModem instruction whenever the TC
temperature exceeds 85°F. To complete the system, provide a PC running
LoggerNet with a phone modem connected to the phone line dialed.

EndProg
In the above data callback program, the phone number is dialed in the
DialSequence/EndDialSequence using the DialModem instruction. Any
needed re-dials are handled by EndDialSequence (DialSuccess).
LoggerNet recognizes the incoming call as a data callback by the arrival of the
“Public” and “Callback” strings sent by the SendVariables instruction in the
Table and Field parameters (visible in low-level log for ComPort). Callback
must be enabled in both the station and the ComPort screens.
The 25 second SendVariables timeout (2500 hundredths of a sec) allows the
slow phone connection time to build.
The program should be available for download from our website under
Support/Downloads/Program Examples.
5.3.2 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
17
COM320 Voice Communications Modem
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.
5.4 Answer in Data Mode
In most applications the COM320 will answer with voice prompts and phrases.
If a phone modem was used in making the call, in order to establish a data
connection, a series of commas followed by a “9” would be appended to the
dialed phone number to switch the COM320 into a data mode.
Some applications may require the COM320 to answer in a data mode without
the intervention of sending the “9”. This can be done via datalogger control by
having a “#9” as the last or only word in a VoiceSpeak instruction. Example:
VoiceSpeak(“#9”,0).
You can also force the modem to hang-up by using the word “#HANGUP” as
the last or only word in the VoiceSpeak instruction.
5.5 LoggerNet
By default the COM320 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 COM320 also has the ability to function in data
mode. In data mode, the COM320 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.
18
For scheduled (or manual) collection you change the COM320 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 datalogger’s DialSequence instruction changes the
COM320 from default voice mode to data mode.
The commas create a delay so that the “9” is received by the COM320 during
the voice announcement. When the COM320 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 COM320 and enable data mode the dial script becomes:
In LoggerNet a comma represents a 2 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. The COM320 must be speaking when the “9” is sent.

6.3 Grounding the COM320 System
Connect the green 14 AWG grounding wire (provided with the COM320) to
the GND terminal on the COM320 and to the station enclosure’s earth ground
connection. It is important that you connect the COM320 and datalogger
directly to a high quality earth ground. Read the datalogger manual section on
GROUNDING for details on creating such an earth ground.

6.4 Telephone Service
Telephone companies occasionally make changes in their equipment,
operations, or procedures. If you have any questions about your telephone
line, such as how many pieces of equipment you can connect to it, the
telephone company should be able to furnish this information upon request. If
the telephone company requests information from you concerning the
equipment that you have connected to your telephone line, the COM320 label
shows its FCC registration number and ringer equivalence number (REN).
COM320 information pertaining to the FCC and Industry Canada is available
in Appendices B and C.
If any of your telephone equipment is malfunctioning, you should remove it
immediately from the telephone line as it may damage the telephone network.
If the telephone company notices a problem from their end, they may
temporarily discontinue service. They should notify you in advance of
disconnection and give you opportunity to correct the problem. If not feasible,
they should notify you as soon as possible.
22
NOTE
If the local phone company does not provide phone-line surge
protection, a Campbell Scientific surge suppressor should be
used. Refer to Section 6.5 for more information.
6.5 Connecting to a Surge Protector
Campbell Scientific offers two surge protectors (CSI model 4330 and CSI
model 6362). The 4330 and 6362 are essentially the same, except the 6362 has
hardware for mounting to an enclosure backplate.
COM320 Voice Communications Modem
NOTE
CAUTION
The 4330 is also known as the 2374-01.
The 4330 and 6362 have a protector element for each line that consists of a
heavy-duty-rated, two-element gas tube, an external backup gap assembly, and
a switch-grade shorting mechanism. The gas tubes (tip and ring) are sealed in
a fire-resistant plastic body. DC Breakdown @ 100 V/sec is 300 to 500 volts;
DC extinguishing @ 52 V, 135 V, and 150 V is less than 150 milliseconds.
Figures 5 and 6 show the wiring for connecting the surge suppressor. Color
coding of wires may vary. The important consideration is to follow TIP all the
way through and RING all the way through. Getting wires crossed typically
does not damage anything. The phone line just will not work until the wires
are straightened out.
Phone wires are live, typically with low voltage (30-50
Vdc). While not harmful in most situations, Campbell
Scientific recommends installing the surge protector in dry
weather only by technicians with a healthy heart.

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
1) The COM320 is connected to a digital rather than an analog phone line.
2) The COM320 configuration was changed from its default factory settings
(see Appendix D).
Data Mode — Can’t connect to the station with LoggerNet software.
1) No commas and/or “9” added to the dial string in LoggerNet to
temporarily put the COM320 into data mode.
2) The “9” is being dialed before the COM320 ‘picks up’ and voices the
announcement (not enough commas).
3) No phone number in the LoggerNet dial string.
4) COM320 is connected to a digital rather than an analog phone line.
24
5) LoggerNet Setup configured for the wrong PC modem.
6) LoggerNet configured for a baud rate the station cannot handle (try 9600).
7) COM320 configuration was changed from its default factory settings
(see Appendix D).
7.2 Communications Problems
Voice Mode
1) Can’t get beyond the initial voice announcement
a) The security code was not received. Try pressing # again, then xxx#
again (where xxx = modem security code).
2) Pressing handset keys sometimes fails to produce the correct response.
a) Handset keys not being pressed long enough.
b) Key presses (especially # #) were not spaced far enough apart and the
station is waiting for the last key (#).
c) Phone line introducing excessive noise or signal attenuation.
d) Handset introducing excessive noise or producing too low signal
levels.
3) Station has become unresponsive (try the following in the order given).
COM320 Voice Communications Modem
a) Press # which will usually announce the current menu again.
b) Press five or more * (star) keys in rapid succession to recover.
c) Allow station to time out and disconnect (usually 15 – 40 sec, rarely 5
min), then call again.
4) Volume levels vary.
This is normal due to the PCM voice encoding compression scheme.
Sometimes the modem will negotiate a higher volume for a given
connection.

that designed for the COM320 modem.
9) The program should now send the operating system to the modem.
Interrupting this process may corrupt the modem operating
system.
FIGURE B-1. Send OS Screen in Device Configuration
B.5 Changing COM320 Settings
There are two items that can be configured in the COM320, the number of
rings before the COM320 answers and the country code. You will need the
Campbell Scientific Device Configuration Utility ver 1.12 or newer and a USB
Type-A male to Type-B male cable to change these settings.
1) You must remove the top cover of the modem to expose the USB port.
This is done by first removing the five Phillips head screws on the sides of
the COM320.
B-5
Appendix B. Updating and Configuring the COM320
2) You must also provide a power source (+12VDC) for the modem. This
can be done by applying power on the green 12Vand G terminals on the
device or plugging the modem into the CS I/O port of a datalogger.
3) Connect the COM320 USB port to one of the USB ports on your computer
and wait for the computer operating system to load its device drivers. If
this is the first time a COM320 has been plugged into your computer, you
may need to install the device driver for the COM320. See B.3 for device
driver installation.
4) Run Device Configuration Utility ver 1.12 or newer.
5) Select COM320 from the Device Configuration utility menu and select the
COM320 tab at the top (Figure B-2).
6) Once the device drivers have been successfully loaded, you should be able
to see the serial port name allocated for the modem in the PC Serial Port
field when you click on the browse button.

7) Click on the Connect button to connect to the COM320 and enter the
settings editor (Figure B-3).
FIGURE B-3. Device Configuration Settings Editor
CAUTION
When doing datalogger to datalogger communications with
the COM320, if more than six rings are specified, the
datalogger may time out before the modem answers;
communication will never be established! Be sure to try
the set up locally before installing at a remote location.
B.6 Retrieving a Vocabulary List
In the case when you are unsure of the COM320’s current vocabulary, a list of
words can be retrieved from the modem. You will need a USB cable, the
Device Configuration Utility or terminal program, a +12 volt power supply and
the COM320 drivers installed on your computer as described in the section
entitled COM320 driver installation instructions.
With the above requirements taken care of do the following:
1) Connect the USB cable between the computer and the COM320.
2) Apply +12 volts to the modem via the CS I/O port from a datalogger or
the +12 volt and ground terminals.
B-7
Appendix B. Updating and Configuring the COM320
3) Launch the Device Configuration Utility and select device type Unknown,
the correct PC serial port connected to the COM320, a baud rate of 9600
and press the connect button.
4) By pressing the “V” key you should see a list of words scroll by in the
Device Configuration Utility terminal window.
If you want to save this list to a file, select the Start Export button and enter a
name for the file it will create. Now press the “V” key and wait until the
words stop scrolling and press the End Export button to create the file This
new file is a complete vocabulary list from the COM320 voice modem.
Start with the CRBasic Editor version 3.1 you can select multiple vocabulary
files from the VoiceSpeak vocabulary window if the file name begins with
voice and ends with .txt (i.e. VoiceTestWords.txt). The file needs to be located
in the directory where the CRBasic Editor looks for its compilers (default
location is C:\Campbellsci\Lib\Compilers).

Appendix C. CS I/O 9 Pin Serial Port
NOTE
Pin Description
The COM320’s CS I/O port is not a standard RS-232
connection.
The COM320 modem connects to the datalogger using an SC12 cable
connected to the datalogger’s CS I/O port. The COM320’s connector
configuration is shown in Figure C-1. Table C-1 shows the I/O pin
configuration, and gives a brief description of the function of each pin.
