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

6.1Security

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 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
