    The COM210 is connected to a CSI datalogger by using a 9-pin subminiature D connector cable. This is the same 9-pin CS I/O connection common to all Campbell Scientific dataloggers (except the CR200 series). This is not an RS- 232 connection. Appendix B describes the configuration of this connector.

    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).
