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.

COM300 Voice Communication Modem 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.

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.
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.
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.
COM300 Voice Communication Modem 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.

Appendix A. CS I/O 9 Pin Serial Port NOTE The modem’s CS I/O port is not a standard RS232 connection. A.1 Pin Description The COM300 modem connects to the datalogger using an SC12 cable connected to the devices’ 9-pin subminiature D-type socket connector. This connector is shown in Figure A-1. Table A-1 shows the I/O pin configuration, and gives a brief description of the function of each pin. CS I/O FIGURE A-1.
Appendix A. CS I/O 9 Pin Serial Port TABLE A-1. Pin Description ABR = Abbreviation for the function name. A-2 PIN = Pin number. O = Signal Out of the datalogger to a peripheral. I = Signal Into the datalogger from a peripheral. PIN ABR I/O Description 1 5V I 5 VDC supply. Not used. 2 SG 3 RING O Ring: Raised by the modem to put the datalogger in the telecommunications mode. 4 RXD O Receive Data: Serial data transmitted by the modem are transmitted on pin 4.
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.

Appendix C. Changing RAM or PROM Chips in the CR10 The CR10 has two sockets for Random Access Memory (RAM) and one socket for Programmable Read Only Memory (PROM). The standard CR10 has 64K of RAM, (a 32K 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.
Appendix C. Changing RAM or PROM Chips in the CR10 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.

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).
Appendix F. Reading Voice Code Information from a “.DLD File 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.
Appendix F. Reading Voice Code Information from a *.DLD File F.3 Security Enabled This last example uses the security code "1234" to allow access to the second level menu. Notice the characters following the "?" at the beginning of the character stream. The security code will always be the very first thing in the imbedded character portion of the *.DLD file. ;|?1234#"☺56&☺57&"# #"☺53&"# #"☺52&"# >\4☺88&☺89&☺109&☺74&☺71&☺71&☺71&"☺109&☺135&☺86&" ☺85&$3☺87&☺122&.\ \4"☺109&☺98&☺191&"☺85&$1☺192&.

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.
