Sorry, if i write on this guide in english.
1.) empty battery of NVSRAM ( CSA/TDS8000 has two NVSRAM, one on PPC Board under x86 board and one on acqusistion board)
Empty battery on NVSRAM under x86 board startup of tek-application.
NVSRAM on acqusitionboard save calibration constant, pleas don't remove him, while unit is turned off.
-> connect RS232 cable with 10pole ribbon connector and female DSUB-9 IDC connector. 1:1 connection of IDC-connetor on both side.
UART-setting: 9600 8N1
On right side, there is 10pole connector. Romoving of blue housing or rack-adapter is requiered.

2.) Setting via debug port
press "any"-key while "autoboot in x seconds"
then press "c" to setting ( "?" for help )
Setting data via console port

3.) NVSRAM saving (NVSRAM on acqusistion board hold calibration data)
Replaced dio.vsh in path "c:\progra~1\tdscsa~1\firmware\dio.vsh" by other version of dio.vsh
(IMPORTANT: pleas don't delete original dio.vsh., you need him after NVSRAM dumping again.)
