Select Either USB or the RS-232C as the PC Communication Interface for the Data Logger Series
The USB-compatible 3912-20 has been added as a
communication base for the flexible Data Logger
Series of compact loggers for measuring information
such as temperature, humidity, instrument signals,
load current, leak current, voltage, pulse signals, and
illumination. There are now two types of
Logger Series: the RS-232C-compatible 3911-20
and the newly released USB 1.1-compatible 3912-
20. The communication bases have proven popular
for their ability to facilitate the collection of data in
the field. Because the 3912-20 is equipped with an
LCD, it also allows the user to easily check data and
change settings.

General Specifications
Use either the 3912-20 COMMUNICATION BASE
(USB) or the 3911-20 COMMUNICATION BASE
(RS-232C) for communication (transferring data and
settings) between a Data Logger and a PC.
The 3912-20 can collect up to 16,000 data elements for
up to 16 channels; when installed in the field, the 3912-
20 can collect data from multiple devices and then send
all of the data to a PC for analysis and processing.
