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. 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 diali

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 da

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. 4) PC208W, Campbell Scientific's comm

Appendix A. CS I/O 9 Pin Serial Port The modem’s CS I/O port is not a standard RS232 connection. NOTE 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. 9 Pin Connector A-1

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. The ring detection circuitry is continuously powered but d

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. To expose the RAM and PROM sockets, remove the two Phillips head screws fro

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. After installing the chip, check for pins that may be bent or
