Interface and data logger with MXI/MXI232 and CXLink
The controller comes with one serial interface which can be connected to a PC with the
optional interface adapter MXI/MXI232 (see interface adapter manual for details) and the
CXLink software.
The CXNup 2B controller features a built-in data logger. The data logger registers up to 2 year
performance data of your PV system, including charge Ah, SOC in the morning etc. System
performance can easily be analyzed with the aid of this history, thus helping the user to get to
know the PV system better.
With the MXI/MXI232 and CXLink application software, the CXNup 2B data logger can be
accessed by a computer. Performance data can be read and displayed via CXLink.
