As PCs do not incorporate RS-485, some kind of converter is needed to be able to connect the PC to the RS-485
bus of the INGECON units. Ingeteam supplies reference AAX7030 (commercial RS-485 to USB converter).
4.1. RS-485 to USB converter
The RS-485 to USB converter and the relevant connectors for connecting a local PC to the units are supplied with
reference AAX7030.
The list of signals is shown in the following table:

installed).
