It would be worth check what the PMD570 does to CTS ( 8 ) in response - hopefully that would confirm that you've identified the connections correctly and I'm reading the description properly.
I'm going to check that next. But first let me ask one more question. If the manual says this:
. 1. The host requests data by setting RTS to L.
2. Upon data request by CTS, the PMD570 responds
by setting RTS to H if not busy.
3. The host checks if CTS is H and stats data output
on TxD.
4. When data output finishes, the host sets RTS to H.
5. The PMD570 checks if CTS is H and sets RTS to L.
Step one seems simple, I should setup a pin as an output and write it low.
For step two should I wire Pin 8 directly to digital pin? If so are there steps that I need to take to protect the arduino from getting fried?
Thanks again folks!
