19.8 Communications specifications

A data logger is normally part of a two-way conversation started by a computer. In applications
with some types of interfaces, the data logger can also initiate the call (callback) when needed. In
satellite applications, the data logger may simply send bursts of data at programmed times
without waiting for a response.
Ethernet Port (CR310 Only): RJ45 jack, 10/100Base Mbps, full and half duplex, Auto-MDIX,
magnetic isolation, and TVS surge protection. See also
