PORT EXPANSION EA 9777-2PE (included in EA EVALxxx)
Supply by USB
The optional adapter board EA 9777-2PE
expands the Evaluation board with important
interfaces:
“real“ RS232, RS232 CMOS, RS485, SPI and
I²C.
The board consists of 5 individual adapter
boards, which have to be carefully broken
asunder the perforation.
Each adapter board has two LEDs two indicate
data transfer. In addition there is a DIP-Switch.
The adapters intermit the USB connection
between Evaluation board and PC and
configures the eDIP for the desired interface.
