Different Ways to Transmit Diagnostic Information
By default, diagnostic information from the diagnostic module HD2-DM* is transmitted via the
gateway. It is not necessary to connect neighboring Power Hubs.
Alternatively, the gateway can be bypassed and the diagnostic information can be transmitted
via a separate bus. In this case, neighboring Power Hubs need to be connected using the ACC-
MB-HDC diagnostic link cable. The last Power Hub in a row has to be fitted with a final
motherboard link (see picture below).
