Hinweis

Please also note that the COM interfaces may only be physically connected once !.

Interconnection is provided either with a physical RS-232 or an RS-422/485 connection.

 

Hinweis

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.
