Help Please - Trimble 4000SSi Configuration
Much success. Both methods worked !
- via serial port, with modified "LOADER.EXE"
- via frontpanel. I found the key sequence : power on normally; go to the Modify menus, press "More" to get to the last page, then enter "567355" . Easy to remember, that's "OPTION".
- enter password (indeed, generated from the unit's serial # and specific option value, so in my case "EE68EF4DF8" to activate the 1PPS option. This code will not work on any other unit of course.
Funny story : I modified my battery caddy to add a more convenient DE9 serial connector, but I realized too late that the caddy uses the "PWR2-3" connector which only has the signals for serial port #3. That is one of the options that needs extra hardware. My unit lacks that, so I now have a decorative serial port!
Since the code and serial numbers seem to both be 10-digit numbers in hexadecimal, I wonder if it could be as simple as a value for the feature XOR with the serial number to make the code?
Hi Bill, you're on the right track ! It is a bit more convoluted though, there's a few extra steps of mangling involved. Do you still have a working 4000 ?
(Side-note : just tested "Trimble DataTransfer" (Windows-based), couldn't get it to run under Wine but it works fine in a VM, with the gps hooked up via an USB-serial converter.
