How the AMC13 IP Address is assigned1. Via the Serial Number | ||||||||

This scheme acts as the "backup" plan, using the jumper connections on T2 to assign IP addresses to both tongues
The address is 192.168.z.x
| ||||||||
Changed: | ||||||||
< < | z is 1 for SN 0-127 and 2 for SN 128-255 and 3 for SN 256-383. | |||||||
> > | z is 1 for SN 0-127 and 2 for SN 128-255 and 3 for SN 256-383. | |||||||
N.B.Serial numbers 0, 128, 256 are not used as it would result in IP address ending in 255, which can cause troubles on some networks. | ||||||||

< < | nSN <= not SerialNumber; mac => x"080030f30" & "000" & not nSN(7 downto 6) & '0' & nSN(5 downto 0) #old T2 mac => x"080030f30" & '0' & not nSN(8) & '0' & not nSN(7 downto 6) & '0' & nSN(5 downto 0), #new T2 mac <= x"080030f30" & '0' & not nSN(8) & '0' & not nSN(7 downto 6) & '1' & nSN(5 downto 0); #all T1 | |||||||

nSN <= not SerialNumber; mac => x"080030f30" & "000" & not nSN(7 downto 6) & '0' & nSN(5 downto 0) #old T2 mac => x"080030f30" & '0' & not nSN(8) & '0' & not nSN(7 downto 6) & '0' & nSN(5 downto 0), #new T2 mac <= x"080030f30" & '0' & not nSN(8) & '0' & not nSN(7 downto 6) & '1' & nSN(5 downto 0); #all T1 | |||||||
So all MAC addr start with 08-00-30-F3. | ||||||||

This results in a range of 00-00 to 01-FF for AMC13 serial# 0-255
and 04-00 to 05-FF for AMC13 serial# 256-511.
