Appendix A. Installation Scenarios
A.4 Example 4: Phone-to-RF Base
In this example, a COM220 phone modem and Master radio are connected
without a datalogger to a network of CR1000s in the field (see FIGURE A-8
and TABLE A-4 ). The computer running LoggerNet uses a phone modem to
call into the Master site and connect to the rest of the network. The rest of the
network can be configured as in other examples. In this configuration,
datalogger-to-datalogger communications and datalogger call-back is NOT
supported; see Example 5.
