Hi guys
I have been working nicely with an industrial scanner that is controlled by a Linux PC via an ethernet cable, but the hard drive has died I need to get it working again.
The problem is that the main PCB has a Realtek RTL8019AS ethernet controller chip, which I believe is used in the most basic way possible, applied straight off-the-shelf and unconfigured.
To utilise the controller ARP commands are used to assign an IP address to the chip’s MAC address e.g. something like:
arp -s 192.168.2.5 00-05-a4-00-a8-f8
Unfortunately the actual MAC address was lost along with the HD :-(
Any ideas how I might find the MAC address again?
The only thing I could have a reasonable guess at is that the chip will have a default subnet of 255.255.0.0 or 255.255.255.0
Fingers crossed and many thanks in advance.
Tony
