COM210 Telephone Modem 1. Introduction 1.1 General Description The COM210 Modem is a 9600 baud phone modem employing the Hayes AT command set. Its primary use is as a remote site phone modem connected to a CSI datalogger. The modem is powered and enabled by the battery-powered datalogger. When not active, the COM210 draws less than 120 µA from the datalogger’s 12 VDC output. The COM210 is a drop in replacement for the COM200.
COM210 Telephone Modem 2. Specifications • Bell 212A, CCITT V.22, and CCITT V.32 compatible • Full duplex at 9600 (default setting) and 1200 baud to datalogger • V.
COM210 Telephone Modem Current Campbell Scientific dataloggers provide 12 VDC to the COM210 via the SC12 cable (Figure 2). Older dataloggers do not provide 12 VDC on the datalogger's CS I/O 9 pin connector. When used with the older dataloggers listed in Table1, 12 VDC and ground need to be connected via the green power connector on the side of the COM210 (see Figure 3). Table 1.

COM210 Telephone Modem 4. Troubleshooting When the Campbell Scientific software cannot establish a link to the remote datalogger that is connected to the COM210, check the following: 1) Verify the modem initialization settings have been changed for the specific calling modem on the computer. See software manual and/or help screens for more information. 2) 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.
COM210 Telephone Modem To comply with FCC rules and regulations, all repairs on the COM210 modem must be performed by Campbell Scientific, Inc. or an authorized agent of Campbell Scientific, Inc.

Appendix A. Modifying the Non-Volatile Memory To modify the COM210’s settings, one must communicate directly to the COM210. This may be accomplished by using one of the two methods below. CAUTION Changing any of the modem's settings may result in communication problems. After changing the settings, try the modem locally before installing it at a remote location. To speed problem resolution when contacting Campbell Scientific for support, please inform us of any modem setting changes that have been made.
Appendix A. Modifying the Non-Volatile Memory FIGURE A-1. LoggerNet Screen A.2 Remote Communication to the COM210 To remotely communicate with the COM210, program the datalogger to initiate a call to it using a program similar to the Example Program 1.* After this program runs once, the modem is now programmed and the actual program one wants to run may now be downloaded to the datalogger.

Appendix C. Theory of Operation C.1 Theory of Operation The COM210 modem is used to transmit data over bandwidth-limited channels such as telephone lines by modulating audio tones. The COM210 uses various modulation schemes including FSK (Frequency Shift Keying), TCM (Trellis Coded Modulation), QAM (Quadrature Amplitude Modulation), and DPSK (Differential Phase Shift Keying).
