Option, have to be ordered.

|
Please note that the COM interface may only be physically connected once!
Interconnection is provided either with a physical RS-232
or an RS-422/485 connection.
|

|
USB connections USB0 and USB2 as well as USB1 and USB3 are wired in parallel. The USB connections USB0 and USB2 as well as USB1 and USB3 must therefore not be used at the same time !
This does not apply to devices of HW Rev. 3, where four independent USB ports have been implemented.
