Ethernet communication PMAC2A/PC104


Recommended Posts

I have troubles communicating with a Pmac2A/PC104 through Acc-2P.

I am able to program the IP address, the card replies to ping (both from Pewin32Pro2 and "dos" command) but refuses to communicate.


The CPU is a 80 Mhz 5CF option.


Since I have another identical CPU (with opt12 added) I tried with this one and.... this way it works, so it's not a fault of the ACC2P.


I tried resetting the card with E3 jumper with no result.

Swapping the CPUs I noticed that with the "bad" one if I plug the USB cable with the PMAC already powered windows says that the USB device could not be recognized, but if I power the device with the cable already inserted it is correctly recognized (tough it doesn't communicate through USB or ETH)


Any hints?


Both boards are new, assy 603670-109
