As far as I can see, this PLC only has an ethernet port. I've been trying to figure out the IP address, with no luck so far.
I'm assuming that, because the part number includes 253 - i.e. in the 200 range, I'll need to use Step 7 Micro/Win. I've just had to use Micro/Win to get an upload from a Siemens S7-200 PLC
