1. Introduction

The COM310 is a voice-synthesizer modem that supports the PakBus and
mixed-array dataloggers that have voice capability (see Section 4.3). The
COM310 allows them to announce by telephone the data stored in variables or
input locations, the status of control ports, and the status of user flags.
Included is the ability to toggle datalogger ports and flags. You can program a
datalogger so you can call-in to the station and listen to announcements, or so
the datalogger calls you with an announcement when specified conditions are
met, or you can program for both.

Although the primary function of the COM310 is voice communications, the
modem is also capable of data communications. In data mode the COM310
supports standard datalogger functions including program send and data
collection. The COM310 supports data callback from the CR1000, CR3000,
and other dataloggers with OSs that support it. The CR10X, CR510, and
CR23X mixed-array OSs support data callback but their PakBus OSs do not.

This manual provides information regarding COM310 specifications,
installation, and operation. Quick Start (Section 3) presents an example
CR1000 voice callback/callin program with descriptions of the code.

a Section 6.3 explains how to make a good earth ground connection to maximize

protection of the COM310 against lightning and electro-static discharge.

3. Quick Start

NOTE

For information regarding the COM310 theory of operation refer to Appendix
A of this manual.

This section presents Basic_Voice_2.cr1 an example voice callback/callin
program written to demonstrate functions of the COM310. It can serve as a
starting point from which you build your own application program. Test well
the auto-disconnect 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) COM310 (OS01062006.SR 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

Some office phone lines are digital and the COM310 cannot
interface to them. Connect the COM310 to analog phone lines
only.

2

You will also need:

1) IBM

2) LoggerNet 3.15 or later installed on PC.

TM

compatible PC with available COM port

Unlike the CR10X, CR510 and CR23X where voice code is appended to a
finished measurement program using LoggerTalk software, the CR1000 voice
code is created along with the measurement program using the CRBasic editor.
It is recommended you finish and debug the voice portion of your 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 your
custom voice program and merge it with your application program.

Step 1 – LoggerNet Setup

1) In LoggerNet Setup create the following device map

COM310 Voice Communications Modem

2) Configure ComPort and PhoneBase for your PC’s phone modem.

3) Configure PhoneRemote to include the COM310’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) Connect CR1000 to PS100 (turned off).

3) Connect SC12 cable from COM310 to CR1000 CS I/O port.

4) Connect analog phone line to COM310.

5) Turn on PS100.

6) Connect prepared TC to CR1000’s DIFF 7 analog input.

7) Connect LED with 1000 Ohm resistor connected to anode lead from C1 to

G (resister to C1).

3

COM310 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 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, Tools, File Control send

VOICE.TXT (typically in C:\Campbellsci\Lib\Compilers) to the CR1000.

7) ConnectScreen send BASIC_VOICE_2.CR1 to CR1000phone.

If you send BASIC_VOICE_2.CR1 before VOICE.TXT, you’ll see some

NOTE

errors. In this case just send VOICE.TXT followed by
BASIC_VOICE_2.CR1 again, and it will compile properly.

Step 4 – Callin

Step 5 – Callback

8) Close File Control and Disconnect from CR1000phone

9) 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 COM310.

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

4

COM310 Voice Communications Modem

Pressing the # key you should hear:

C R ONE THOUSAND STATION
PRESS ONE TO HEAR A SENSOR VALUE
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 keys

c) Press the same key again if a wrong response is gotten

d) If no response, try pressing key again or press # key to recover

e) If unresponsive, try rapidly pressing a series of five * keys to

disconnect station.

f) Worst case, 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 our website under Support/Downloads/Program
Examples. Following the program is a description of its main sections.

Example Program Description

Basic_Voice_2.cr1 has five main sections:

1. VoiceSetup( ) - handles auto-disconnect.

VoiceSetup( )

WARNING

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 finds, 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 COM310
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 COM310 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.‘

The VoiceSetup SecsOnLine setting is important as it
hangs up (auto-disconnects) the modem in case
someone cradles the phone or leaves the phone off-hook
without pressing star keys for an orderly “good-bye”
disconnect. Test well your 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.

10

Voice Beg / EndVoice

The VoiceBeg / EndVoice instruction pair enclose the code that is executed
when the datalogger detects a ring from its voice modem (at call in).

CallInVoice Subroutine

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.

CallOutVoice Subroutine

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.

COM310 Voice Communications Modem

SlowSequence

Contains code that continually executes looking for the Diff 7 thermocouple to
exceed 85F 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 COM310 Modem

Connecting a COM310 voice modem to a datalogger provides all COM210
supported functions plus the following:

• Voice retrieval of data (user or datalogger initiated)

• Reading/Toggling of datalogger control ports

• Reading/Toggling of program Flags

The COM310 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 COM310’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.

11

COM310 Voice Communications Modem

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

6.6).

4.3 Voice Capable Dataloggers

There are several Campbell Scientific dataloggers that are capable of voice
communications. The following sections tell which mixed-array, PakBus, and
table-based dataloggers are capable of which functions.

4.3.1 Mixed-array

A CR10X, CR510, or CR23X with mixed-array OS is capable of COM310
voice communications.

4.3.2 Table Data

4.3.3 PakBus

The TD OSs (OS10XTD, OS510TD, and OS23XTD) do not support any
COM310 communications. For data collection you can use a COM210
modem.

With PakBus dataloggers the COM310 supports such functions as program
send, data collection, and clock check. The following voice/data functions are
supported as well.

COM310/PakBus Datalogger Support

DATALOGGER Voice Callback Voice Callin Data Callback

CR1000 yes yes yes

CR10XPB yes yes no

CR510PB yes yes no

CR23XPB yes yes no

The COM310 supports concurrent communications. PakBus dataloggers with
multiple peripherals (COM310, RF450, RF401, MD485, NL100, CR10KD,
CR1000KD, and SC32B) can communicate simultaneously via those
peripherals.

4.4 Telephone

A touch-tone phone is normally used to call the COM310 modem. A rotary
phone will work if the programmed voice announcements do not require you to
navigate through the COM310’s menu system.

COM310 Voice Communications Modem

NOTE

The COM310 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 COM310. Of course,
any phone may be used to call in to or receive callbacks from the
COM310. A touch-tone phone is necessary for input.

5. Datalogger Voice Programming

The voice code for the CR1000 and other voice capable CRBasic dataloggers
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.

With the CR10X, CR510, and CR23X dataloggers, voice code is added to
Edlog created dld files using LoggerTalk software.

5.1 Features

The voice instructions listed in 5.2.1 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.

5.1.1 Callback

5.1.1.1 Data Callback

For Edlog dataloggers, use multiple P97s with a different flag for each P97.

Callback is the ability of a datalogger/COM310 station to initiate a phone call
‘back’ to a PC running LoggerNet (data mode) or to a telephone (voice mode).
You can include data callback and voice callback code 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.

A CR1000 program uses a SendVariables instruction to effect a data callback
(see example data callback program below). No callback ID is used.

A CR10X, CR510 or CR23X program uses a P97 typically with a “42” in
Parameter 1 for 9600 baud. A callback ID is required in P97’s Parameter 8
matching that assigned in the LoggerNet Setup.

Data callback is not supported in table-based or PakBus OSs for the CR10X,
CR510, and CR23X.
