Installing the device
When you install a LGR-5320 Series device, you can set it up to operate in one of the following modes:
 USB mode—The device is connected to a USB port on your host computer, and controlled by USB
command. Use this mode to configure and load logger settings to a logger using DAQLog software.
 Logging mode—The device has no active USB connection, all buttons on the logger are enabled, and the
device can read from or write to an installed SD card. Use this mode to load configuration settings and log
data using LGR-5320 Series logger features.
LGR-5320 Series logger operation modes are illustrated in Figure 2.
