Function
The serial W&T module base board 13011 together with W&T
interface modules provides two independent serial interfaces
with galvanic isolation of 1kV DC as well as two serial interfaces
without galvanic isolation. Integration of the interface-specific
components on the cards in the form of interchangeable inter-
face modules provides for an optional mixed configuration of
the cards with different interface types. This means for examp-
le you can easily implement an RS232 interface for connecting
a mouse and a 20mA interface for connecting a controller on a
single card.
Wiring configuration
The serial TTL interface on the base board is implemented as a
12-pin PCB connector. The connector pin assignments are
shown in the following table:
Pin 1 of the connector is indicated by a rectangular soldering
pad.
