I'm trying to connect my mitsubishi A2AS1 PLC to my PC with GX Developer using a cable I made (based on a lot of different sources):

[replace spaces with dots]
The thing is, of course, it doesn't work. That is to say it works with a loopback test but the PLC does not respond to a connection attempt from Developer. So my question is: is there a mistake in the schematics?
I was thinking maybe I should implement the CTS and RTS I/O ports of the CP2102 but I have no more MAX3467 chips so the CTS and RTS would be only 3V in amplitude and I'm not sure that's enough for the A2A.
Anyway, I'd appreciate any suggestion.
