Question: Which DB-9  connector of CY3684/81 do I plug my serial cable into?

 

Answer:

There are different versions of the monitor code which load into on-chip or off-chip memory, and use SIO-0 or SIO-1, as indicated by the name and the readme.txt file. Just make sure that the monitor file you load corresponds to the connector you have plugged in the serial cable.
