- Open your terminal emulator, hold down the y key while powering up the UDS1100 to open Monitor Mode without network connections

- Change the MAC address sequence in the first line from "00 20 4A 9B 9C 49" to "00 20 4A A2 29 E0"
- Then you need to recalculate the checksum for the whole of the first line.
- So in HEX 20+10+20+4A+A2+29+E0 = 245
- discard the most significant digit and subtract from FF to get the 15s complement:
- FF-45=BA
- add 1 to get the 16s complement
- BA+1=BB
- So the old checksum (E6) is now edited to read BB
- Add in an extra line above the first line with the string S4

- Select all 6 (six) lines of the TXT file, and copy them to the paste buffer or clipboard

- Disconnect the session
- Power off the UDS1100
- Open up your terminal emulator again, press the x keep (repeatedly) while powering up the UDS1100.
