Overview
1.1 Product Overview
The 3912-20 COMMUNICATION BASE is designed to load data
from the Logger Series and transfer loaded data to the PC via a
USB interface. Data can be loaded from the 3912-20 onto the PC
for analysis using the software included with the 3912-20 (Communication Utility).
Features
• Capable of collecting up to 16 channels of data when connected
to logger.
• Capable of storing setting conditions (clock, interval, recording
start time, etc.) in memory and loading settings to logger when
connected to logger.
• The LCD allows data obtained from the Logger Series to be
viewed on the spot, and allows the data-transmission settings
that will be transmitted to the Logger Series to be changed.
• Data obtained from the Logger Series is stored in nonvolatile
memory, thus protecting it even when the battery power is low or
during battery replacement.
• USB1.1 (12 Mbps) ensures the high-speed transfer of stored
data to the PC.
• The 3912-20 is powered from the USB when conne cted to the
PC, thus preventing its battery power from being exhausted. In
addition, a battery indicator is available for monitoring of the battery replacement period.
• Packaged software allows personal computer to load up to 16
channels of data from logger series. Loaded data can be applied
to display graphs and calculate maximum value, minimum value,
etc.

indicator on.
Button press does
not enable sending
settings to logger
nor receiving data
from logger.
• Check and see if the batteries are properly
installed and not weak.
• Is logger properly connected to the 391220?
When logger is not properly connected,
error occurs during optical data transfer
turning LED error indicator on.
• Is LED power indicator blinking?
When batteries are weak, LED power indicator starts blinking and communication with
logger cannot be established.
• Is logger in recording status?
When logger is recording, data cannot be
transferred. Executing data transfer during
recording results in error and LED error indicator starts blinking.
• Is logger set to sleep?
Press logger INTERVAL button and display
interval setting display.
When interval setting saved in the 3912-20
is set at 1 second, interval setting cannot be
sent to the 3631-20 to the 3635-2X and the
3641-20 which minimum interval is at 2 seconds.
Similarly, if the recording-interval setting is
one day, the setting can only be sent to the
3639-20.
