8.1 Ports
RS-232
The RS-232 port is the main port used with Campbell Scientific dataloggers.
Its function is described throughout this manual.
USB
The USB port is not used in Campbell Scientific applications.
Ethernet
The Ethernet port may be used in place of PPP Mode to get to the IP stack of
the datalogger. However, this method comes with higher current drain for both
the modem and the datalogger. See Appendix
D , Using the RV50 Ethernet Port
(p. D-1)
, for more information.
