Connecting the Logger to the PC
If you would like to configure a logger or to retrieve data from a logger, a connection
to the logger has to be established first. This connection can be either established via
the VK 77 USB cable or via radio communication using the E-Box.
4.3.1
Radio Communication via E-Box
Introduction
The E-Box, while connected to the PC via USB interface, offers you the possibility to
access all loggers in a range of up to 100 m (depending on the environmental
conditions) via radio link. That way, you are able to initiate a data transfer without
sitting next to the device.
If a logger receives a signal from the E-Box addressed to it, it changes from energy
saving mode to data transfer mode. During data transfer, the I/O control lamp
is lit green.
Design of the E-Box
The following figure shows the E-Box:
