I think IP address or display settings cannot be stored to that EEPROM, it contains oscillator steering parameters etc. That is because this EEPROM is write protected by jumper JP4, so any user settings cannot be there. You only need to edit the EEPROM content if you change to different oscillator. To do any changes there JP4 must be shorted to enable writing. From my TS2100 I have stored two EEPROM dumps: With original TXCO: 0e 5b 45 4b 00 00 00 46 31 30 34 30 38 30 37 39 00 00 00 00 00 00 00 00 00 a0 6e 04 1f d3 56 43 58 4f 00 00 00 00 00 00 00 00 00 00 00 00 ff ff ff eb 00 00 00 02 3f 73 33 33 00 04 00 00 00 00 00 24 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 After upgrading MTI OCXO: a5 73 9b 52 00 00 00 46 31 30 34 30 38 30 37 39 00 00 00 00 00 00 00 00 00 a0 6e 04 1f d3 56 43 58 4f 00 00 00 00 00 00 00 00 00 00 00 00 ff ff ff eb ff ff ff ec 3f 7f df 3b 00 04 00 00 00 00 00 24 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 So there must be some other place to store the user data. I would look if there's more EEPROMs on the board and does they have write protect jumpers also. Erratic jumper setting there could prevent storing any changes. It may also be faulty eeprom. -- 73s!

Here's mine again: fe 55 73 7c 00 00 00 46 33 30 30 30 30 30 32 31 00 00 00 00 00 00 00 00 00 a0 6e 04 14 4a 56 43 58 4f 00 00 00 00 00 00 00 00 00 00 00 00 ff ff ff ed 00 00 00 14 3f 7f df 03 00 04 00 00 00 00 00 24 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Already replaced the oscillator a while back. Comparing the output to a gps 10Mhz, the original was jittering all over the place and not very nice on an sa either. Didn't have the exact fit, but did have a small ovenised vcxo which had the right vcc and control range. Epoxied that the the board, but had to add a squarer (a single transistor) as it had a sine wave op. So, it's been hacked around a bit already. One thing I did notice in the eeprom, 4th line down, first six bytes, is the ether mac address, but haven't edited any parameters as yet. Right now, it's running on a ups, along with a couple of other what I call, "essential loads" :-). As for user setups, from memory, there are two eeproms on the board, so may swap the other item to see if it fixes the fault...
