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

NOTE
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 9­pin) 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.

For theory of operation for the COM300 modem, refer to Appendix B of this manual.

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.

3.2 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.
CAUTION
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
5
COM300 Voice Communication Modem
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.
NOTE
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.
6
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.
NOTE

6.2 Commercial Mode

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.
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
7
COM300 Voice Communication Modem
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.
