COM310

VOICE SYNTHESIZER

12V

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.

You will also need:

1) IBM

2) LoggerNet 3.15 or later installed on PC.

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).

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

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.

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.
