However, sc9054 will not help with updating the remote sserial firmware. If you want to update the 8I20 firmware via windows I would use a usb-serial adapter and the uflbp utility.

www.mesanet.com/software/parallel/sserial.zip
Has the latest 8I20 firmware (R11)
You will need LinuxCNC master and a sserial FPGA bitfile with a version of
SSLBP newer than rev 33 to update via linuxcnc/standard bitfile/daughtercard
/cables (update in place) using setsserial (take a look at the README file in
utils/linuxcnc)
You can also update the firmware using the windows utility uflbp and a
USB/serial adapter
Also note that the RPD/WPD utilities in the sserial.zip file
are not for the 8I20

I am not sure about the rest, but because the enable inputs are separate, they need to be driven by GPIO rather than anything that the driver sends down the serial link. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto -- Get 100% visibility into Java/.NET code with AppDynamics Lite!

Which pinout differences? I am not aware of any

That should not be.
We made a change in enable and enable masks recently for an OEM
