COM300 Voice Communication Modem
1. Introduction
The COM300 voice-synthesizer modem allows Campbell Scientific's voice
capable dataloggers to transmit, by voice announcement, data stored in input
locations and the current status of datalogger control ports and user flags. With
voice communication enabled, a user can call a datalogger site and listen to
announcements, or the datalogger can be programmed to initiate voice calls
when alarm conditions are met. Though voice communication is the primary
function of the COM300 modem, the device is also capable of standard modem
communications.
This manual provides information specific to the COM300 hardware, including
specifications, installation, and operation. Installation of the LoggerTalk Voice
Communication Programming Software is covered, but use of the software is
detailed in the software's on-line documentation.
2. Hardware and Software Requirements
2.1 COM300 Modem
The COM300 modem (Figure 1) is required at the datalogger site to activate
voice communication. The modem is shipped with an SC12 cable (9-pin to 9-
pin) to connect it to the datalogger's communication port. Surge protection at
the datalogger site is required if it is not installed by the phone company. CSI
offers a surge protector with or without environmental enclosure mounting
hardware (model 6362 and 2372-01, respectively).
The modem’s communication port is configured to be compatible
with Campbell Scientific’s CS I/O port. This is not a standard
RS232 connection. Refer to Appendix A for the configuration of
this connector.

2.2 Voice Capable Datalogger
The following Campbell Scientific array based dataloggers are capable of voice
communication: the CR10, CR10X, CR500, CR510, and CR23X. The CR10
will require a special UVEPROM to enable voice communication. If this
special prom was not installed at the factory, please contact Campbell Scientific
or your Campbell Scientific representative. Appendix C provides information
on installing this UVEPROM.
2.3 Telephone
Typically a touch-tone phone is used to call the COM300 modem. A rotary
phone can be used if the programmed verbal announcements do not require the
user to navigate through the modem's menu system.
2.4 LoggerTalk Voice Communication Programming Software
Datalogger program files created using Campbell Scientific's Edlog program
editor must be modified to include voice communication announcements. This
modification is accomplished using LoggerTalk software, which is shipped with
all COM300 modems. LoggerTalk requires a computer running Windows
95/NT/98.

3. Hardware Installation
3.1 Site Installation
Connection to telephone company-provided COIN service
(Central Office ImplemeNted systems) is prohibited. Connection
to party line service is subject to state tariffs.
The COM300 is designed to be used on standard device telephone lines. The
COM300 connects to the telephone line by means of a USOC RJ11C jack
(standard modular telephone jack).
Connect the cable from the telephone RJ11C jack to the modem as shown in
Figure 2. If the telephone company has not installed surge protection in the
telephone line (no RJ11C jack), one must install surge protection (Model 6362
or 2372-01) and connect the ring and tip terminal blocks as shown in Figure 3.

3.2 Properly Grounding the COM300 System
Connect the green 14 awg grounding wire (provided with the COM300) to the
grounding terminal (GND) on the COM300 and to the enclosure’s earth ground
connection. If the site does not have a grounded enclosure, connect the ground
wire directly to an earth ground connection. The datalogger ground should also
be tied to the earth ground.
The modem must be grounded for its transient protection to
work.
3.3 Powering the COM300 Modem
More recent Campbell Scientific dataloggers provide 12 VDC power on pin 8
of the CS I/O 9 pin connector. For dataloggers that do not provide 12 VDC on
the datalogger's CS I/O 9 pin connector, 12 VDC and ground must be
connected via the green power connector on the side of the COM300 (refer to
Figure 4). Table 1 lists the Campbell Scientific dataloggers that require direct
12 VDC connection to the COM300.

3.4 Telephone Service
The goal of the telephone company is to provide you with the best service it
can. In order to do this, it may occasionally be necessary for them to 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 will provide this information
upon request. If the telephone company requests information concerning the
equipment which you have connected to your telephone line, the FCC
registration number and the ringer equivalence number (REN) of the COM300
COM300 Voice Communication Modem
6
are listed on its label. Additional technical information from the FCC and IC
on the COM300 is available in Appendix D and E, respectively.
If any of your telephone equipment is not operating properly, you should
remove it immediately from your telephone line, as it may cause harm to the
telephone network. If the telephone company notes a problem, they may
temporarily discontinue service. When practical, they will notify you in
advance of this disconnection. If advance notice is not feasible, you will be
notified as soon as possible. When you are notified, you will be given the
opportunity to correct the problem and informed of your right to file a
complaint with the FCC.
3.5 Repairs
To comply with FCC Rules and Regulations, all repairs on the COM300 must
be performed by Campbell Scientific, Inc. or an authorized agent of Campbell
Scientific, Inc.
4. LoggerTalk Software Installation
LoggerTalk Voice Programming software is provided with the COM300. This
software is used to edit datalogger program files (*.DLD) to include code that
activates voice communication in voice capable dataloggers.
LoggerTalk requires a computer running Windows 95, Windows NT, or
Windows 98 with a 3.5" floppy drive. Before beginning installation, close all
active programs including virus and mail applications. To install LoggerTalk,
insert disk 1 into your floppy drive. From the Windows Start Menu, choose
Run. In the dialog box that appears, type in A:\Setup (this assumes A: is the
drive letter assigned to your floppy drive). The installation program will guide
you through the remainder of the setup.
If an error occurs at the beginning of installation, check your
Windows temp directory. (This is typically C:\Temp or
C:\Windows\Temp. If you are unsure, go to an MS-DOS prompt
and type SET. Look for a line that displays TEMP = and note
the directory name.) Move all files to a different directory. This
directory is used during software installation. The TEMP
directory has a file limit that, if close to being exceeded, will
prevent installation of the software.
Operation of LoggerTalk is not covered in this manual. LoggerTalk has an
extensive help system that can be accessed at any time by pressing the F1 key,
or by selecting the Help menu item from the main window and by pressing the
Help button on screens that have it. Two tutorials are included: a basic tutorial
that walks you through creating voice strings, downloading the modified
program to the datalogger, and navigating through the voice modem menus, and
a more advanced tutorial for setting up voice callback. Example program files
are included for use in the tutorials. If you do not have prior experience in
editing datalogger program files with a Campbell Scientific editor, we suggest
that you begin with the basic tutorial and peruse the help system for any
questions you might have.
NOTE
COM300 Voice Communication Modem

Appendix F of this manual provides a guide to interpreting the code that is
added to the end of the datalogger program file for voice communication.
5. Using the COM300 for Standard Modem
Communications in PC208W
The COM300 can be used for standard data transmission in PC208W. To
establish data communication with the COM300, the dialing string (phone
number) must be modified in PC208W to disable voice communication for the
duration of that connection (the dialing string is found on the Hardware Tab of
PC208W's Setup window).
To disable voice communication, insert three commas and "9" at the end of the
dialing string for your datalogger. For example, if the telephone number for
your datalogger is "555-4321" you would need to make the following additions:
"555-4321,,,9". Each of the three commas inserts a 2 second delay. The 9
disables voice communication. Depending upon the length of time required to
establish connection with the modem, you may need to add more commas.
For information on downloading a datalogger program to the COM300, refer to
the Basic Tutorial in LoggerTalk's on-line help system.
6. Additional Features
6.1 Security
A security code can be used with the COM300 to prevent users from accessing
information beyond the initial messages. If security is not enabled, callers will
have access to all input location data, and can change the status of datalogger
ports and flags. Security is enabled by editing the datalogger program file in
LoggerTalk. Refer to the LoggerTalk on-line help system for further
information. If you forget the security code you can open the datalogger
program in LoggerTalk and review what number you originally entered.
This security code is different than the security code that can be
entered to prevent access to certain datalogger functions. Refer
to your datalogger operators manual for more information.
6.2 Commercial Mode
When in Commercial Mode, the datalogger will announce the initial messages
up to two times and then terminate the connection with the caller. A modem
security code must always be entered in the LoggerTalk software when
Commercial Mode is used.
6.3 Renaming Menu Strings for Input Location, Ports, and Flags
When you call the datalogger, after the initial messages are announced you are
prompted to hear the status of Input Locations, Ports, or Flags. These three
NOTE
COM300 Voice Communication Modem
8
terms can be renamed to something more descriptive using LoggerTalk. A
dialog box to make these changes is invoked by selecting the Menu Strings
button from the main LoggerTalk window. Refer to the LoggerTalk on-line
help system for more information.
6.4 Using the COM300 to Hear Final Storage Data
Output data is normally stored in the datalogger's ring memory (Final Storage).
The COM300 can access data in input locations only; it cannot access Final
Storage data. In order to hear Final Storage data, it must be redirected to an
input location. This input location can then be accessed by the COM300.
Datalogger Instruction 80 is used to redirect output data to input locations.
Refer to the datalogger's operators manual for more information on this
instruction, and to Appendix G for an example program using P80.
7. Callback - Datalogger Initiated Calls
The datalogger can be programmed to initiate a call to one or more telephone
numbers when a specific condition is met. Typical use of this feature is for the
datalogger to call a computer running PC208W and transfer Final Storage data
to the computer. However, this feature can also be used with voice
communication. When callback is initiated, the datalogger will call the defined
telephone number(s) and a message will be announced. This is particularly
useful in alerting those monitoring the datalogger system of alarm conditions.
LoggerTalk's on-line help system includes a tutorial to guide you through
setting up a datalogger initiated voice callback. The datalogger's operators
manual also includes general information on the callback feature.
You can intermix voice and modem calls in the same program. Make sure you
are not using the same flag for a voice and a modem call.
8. Troubleshooting
8.1 For Problems Encountered When Making Voice Calls
1) Can you attach a normal analog telephone to the line and make a call out?
If not, contact your local telephone company. If you can make a call out
but the connection is poor or faint, contact your local telephone company.
2) Verify the COM300 is receiving 12 VDC. If the COM300 is receiving 12
VDC from a separate power supply instead of the datalogger, is the ground
of the separate power supply connected to the datalogger’s ground?
3) Verify the COM300 is the only Modem Enable device connected to the
datalogger. Other common Campbell Scientific modem enable devices are
the SC32A, some RF modems, and the MD9.
4) Verify the datalogger is turned on.
5) Verify the datalogger has power on its 5 V output.
COM300 Voice Communication Modem
9
8.2 For Problems Encountered When Making Data Calls
1) Verify you have selected the correct calling modem from PC208W's setup
screen.
2) Verify the COM port you are using is activated. As a power saving
feature, some notebook computers do not automatically activate the COM
ports.
3) Verify nothing else is using the same COM port on the computer. Even if
a program is minimized in Windows, it may have a lock on the COM port.
4) PC208W, Campbell Scientific's communication software, has a log level
I/O log that will display an activity of communication as the link is being
established. Assuming the above items are O.K., the software log should
display something such as “ATDT#######”. Where the #### is the
telephone number listed in the dialing path of the software for the
datalogger you are trying to call. As you are connected to each device in
the communications link, this will be reflected in the activity screen. This
may help to pinpoint which device in the communications link is failing.
To comply with FCC Rules and Regulations, all repairs on the COM300
modem must be performed by Campbell Scientific, Inc. or an authorized agent
of Campbell Scientific, Inc. For assistance in installation, troubleshooting, or
for repair, contact Campbell Scientific:

Appendix B. Theory of Operation
B.1 Theory of Operation
The COM300 modem is used to transmit data over bandwidth-limited channels
such as telephone lines by modulating audio tones, using Phase Shift Keying
(PSK) at 9600 or 1200 baud and Frequency Shift Keying (FSK) at 300 baud.
The telephone company gives a 40 to 150 VRMS, 20 Hz signal on the
telephone lines to signify a ring, which is typically on for 2 seconds and off for
4 seconds. The ring detection circuitry is continuously powered but draws less
than 2 µA. The ring signal is passed on to the datalogger through an opto-
coupler. The datalogger responds by addressing the modem synchronously
(pins 6 and 7) which switches on the 5 VDC power to the modem. The modem
then answers and remains off-hook until it loses the carrier or the datalogger
addresses a shut down command to the modem. The datalogger sends the shut
down command either in response to an external command or after 40 seconds
elapse without a command. The shut down command switches off the 5 VDC
power to the modem, dropping power to the off-hook relay and thus placing the
telephone line on-hook.
To reject noise common to both telephone lines and to satisfy registration
requirements, the modem circuitry is electrically isolated from the telephone
lines by using an opto-isolator and coupling transformer.

RAM chip in each socket). Earlier CR10s had 16K of RAM (an 8K RAM chip in each
socket).
C.1 Disassembling the CR10
The sockets provided for RAM and PROM are located on the CR10 CPU
circuit card inside the CR10 can. To expose the RAM and PROM sockets,
remove the two Phillips head screws from the end opposite the connectors.
Remove the end cap. The ends of two circuit cards and the RF shield will be
visible (see Figure C-1). Now lay the CR10 on a flat surface, (i.e., a table), and
push on the RF shield with your thumbs while grasping the can with your
hands. Remove the circuit cards from the can. Orient the cards with the
connector on the left and with the card that matches Figure C-2 component-side
up. The Central Processing Unit (CPU) is found at location H-9 and the three
slots for RAM and PROM will be directly beneath it.
C.2 Installing New RAM Chips in CR10 with 16K RAM
The two 8K RAM chips are found at locations C11 and C14. With a small flat
screw driver gently pry out the two 8K RAM chips at these locations and
replace them with the 32K RAM chips provided in the memory upgrade. The
new chips should be installed so the notched end is towards the nearest card
edge. Before pushing the chips into the socket make certain that all the pins are
correctly seated. After installing the 32K chips, check for pins that may be bent
or not firmly seated in the socket. If you notice a bent pin, remove the chip,
carefully straighten it and repeat the installation procedure.
C.2.1 Changing Jumpers
There are six jumpers used to configure hardware for different RAM sizes.
Figure C-2 shows the location of the jumpers and a magnified view of the
jumper settings for different memory configurations. A pin or small screw
driver tip will work best for pulling these jumpers and relocating them.
C.2.2 RAM Test
Attach the CR10KD Keyboard/Display and apply power to the CR10. After
the CR10 executes the RAM/PROM self test, the number 96 should be
displayed in the window. The number is the sum of Kbytes in RAM (64) plus
the number of Kbytes in ROM (32).
Appendix C. Changing RAM or PROM Chips in the CR10
C-2
C.3 Installing New PROM
The PROM chip is found at location C8 on the CR10 CPU board, (see Figure
C-2). With a small flat screw driver, gently pry out the PROM chip and replace
it with the new one. The new chip should be installed so that the notched end is
towards the nearest card edge. Before pushing the chip into the socket make
certain that all the pins are seating correctly. After installing the chip, check for
pins that may be bent or not making contact. If you notice a bent pin, remove
the chip, carefully straighten it and repeat the installation procedure.
To make certain that the new chip is installed correctly enter the CR10 *B
mode (Section 1.6 in the CR10 Operator's Manual) and advance to the second
window. This window displays the PROM signature. The five digit number in
the window should match the PROM signature given with the new PROM
documentation. If the numbers are different, disassemble the CR10 and look
for pins that are bent or not firmly seated.

This equipment generates, uses, and can radiate radio
frequency energy, and if not installed and used in
accordance with the instruction manual, may cause
interference to radio communications. It has been
tested and found to comply with the limits for a Class
A computing device pursuant to Subpart J of Part 15 of
FCC Rules, which are designed to provide reasonable
protection against such interference when operated in
a COMMERCIAL ENVIRONMENT. Operation of this
equipment in a residential area may cause interference
to radio and television reception. The operator must
take whatever measures are necessary to correct the
interference.
The REN is used to determine the quantity of devices which may be connected
to the telephone line. Excessive REN’s on the telephone line may result in the
devices not ringing in response to an incoming call. In most, but not all areas,
the sum of the REN’s should not exceed five (5.0). To be certain of the number
of devices that may be connected to the line, as determined by the total REN’s,
contact the telephone company to determine the maximum REN for the calling
area.
This equipment cannot be used on the telephone company-provided coin
service. Connection to Party Line Service is subject to State Tariffs.
If this equipment cannot be used on the telephone network, the telephone
company will notify you in advance that temporary discontinuance of service
may be required. If advance notice isn’t practical, the telephone company will
notify the customer as soon as possible. Also, you will be advised of your right
to file a complaint with the FCC if you believe it is necessary.

Appendix F. Reading Voice Code
Information from a *.DLD File
When a file is edited and saved in LoggerTalk, the information for voice
communication is added to the end of the *.DLD file. This information can be
verified for accuracy.
A copy of typical voice code is provided below. The numbers between the
"smiley faces" (☺) and the "&" symbols are the numbers associated with the
words used from the word list. The ☺ symbol is equivalent to control code A
(^A). Refer to Appendix H to review the word list used with the COM300.
Several lines of code that begin with a tilde (~) may precede the voice code.
These strings are set up information. The voice code follows this information.
The first line of the voice code is the wording used for input locations. The
second line is the wording used for ports. The third line is the wording used for
flags. The lines following are used for message descriptions. Each message
will terminate with a period.
Notice that line four below starts with ">\4". The > indicates the string is an
initial message. The 4 following the slash indicates the number of digits
following the decimal point that the COM300 will announce for that input
location.
The numbers inside the quotation marks are the words associated with the input
location.
The number following the "$" symbol is the input memory location number
used in the datalogger.
F.1 Typical Voice Code
Following is code for a typical call:
;|#"☺56&☺57&"#
#"☺53&"#
#"☺52&"#
>\4☺88&☺89&☺109&☺74&☺71&☺71&☺71&"☺109&☺135&☺86&"

The above code translates to:
Input Locations
Ports
Flags
(four decimal places) Campbell Scientific Datalogger Program (pause)
(pause) (pause) "Datalogger Internal Temperature" is (input location 3)
Degrees Fahrenheit.
(four decimal places) Datalogger Battery Voltage is (input location 1) Volts.
F.2 Callback Code
If the datalogger has been programmed to initiate voice calls, you will see the
phone number associated with the call command at the very end of the listing.
The flag number used to initiate the call and the phone number will be between
"at" symbols (@).
This example initiates a voice call:
;|#"☺56&☺57&"#
#"☺53&"#
#"☺52&"#
><2\4"☺98&☺191&"☺85&$1☺192&.\
@2555-1234@
|
♣♣
Line four, above, starts out as “><2/4”. The “>” means this message is selected
as an initial message. The “<2” indicates that this message will be spoken if
flag 2 is the flag that initiates callback. The “2” preceding the phone number
“@2555-1234@” means the phone number (555-1234) will be called when flag
2 goes low in the program.
The code translates as:
Input Locations

Appendix G. Using P80 to Redirect
Final Storage Data to Input Locations
The following section of code provides an example of using datalogger
Instruction 80 to redirect Final Storage data to input locations. This is not a
complete program. Instructions would be included prior to this section of code
to measure sensors, perform control functions, and provide initial data
processing. All text entries preceded by a semicolon (;) are comments inserted
by the programmer to explain the instructions.
;The following section of code uses
;program instruction 80 to redirect
;data from final storage to input locations
32: If time is (P92)
01: 0000 minutes into a
02: 60 minute interval
03: 10 Set high Flag 0 ; output data
33: Set Active Storage Area (P80)
01: 3 Input Storage Area ; parameter 3 directs data to input storage
02: 5 Array ID or location ; starting at location 5
34: Maximize (P73)
01: 1 Rep
02: 11 Value with Hr-Min-Sec
03: 4 Loc AIR TEMPC
Every sixty minutes the maximum air temperature will be stored in location #5.
No output data will be sent to Final Storage.
Instruction 80 should follow the instruction setting Flag 0, and should precede
the output instructions. Keep in mind that all output processing instructions
following Instruction 80 will be redirected to input storage until another
Instruction 80 is used or until the program table is executed again (output
defaults to Final Storage Area 1 at the beginning of the program table).
