1.
If it is important to retain the channel programming information in the instrument,
store a copy of the instrument configuration setup on a memory card. Refer to
section on "Using SETUP STORE" in section 3 of the 2635A Data Bucket Users
Manual.
2.
To load the instrument firmware, run ’LOADC1.BAT’ if COM port #1 is to being
used. Otherwise, run ’LOADC2.BAT’ if COM port #2 is to being used. These batch
files execute ’LD2635’ in batch mode with the proper command line switches to
download the default instrument firmware via the proper COM port.
3.
After successful loading of the instrument firmware, the instrument will be reset to
begin normal operation. It is not abnormal to see an "ERROR 6" indication
displayed by the instrument as it begins operation again. This just indicates that the
internal instrument configuration has been reset to factory defaults. If you saved the
instrument configuration during step 1, you can reload it into the instrument now.
Refer to section "Using SETUP LOAD" in section 3 of the 2635A Data Bucket
Users Manual.
4-34. Using LD2635 Firmware Loader Directly
The ’LD2635’ program may be used interactively or in batch mode by using command
line switches. The command line syntax is
LD2635 [/B /Cn /Fname]
where the command line switches are defined as follows:
/B
Execute in batch mode; program exits when firmware programming is
complete. If batch mode is not specified, user is asked whether or not another instrument
is to be updated each time an instrument is completed. (/Cn and /Fname switches must
be included if batch mode is specified.)
/Cn
Use COMM port #n (n = 1 or 2)
/Fname
Download named firmware file to the 2635A
For example, to program multiple instruments with version 6.8 of the instrument
firmware via COM port #2, execute:
ld2635 /fdb_6_9.hex /c2
or to do the same with only one instrument:
ld2635 /b /fdb_6_9.hex /c2
The ’ld2635’ program can be used interactively by running it without any command line
switches. It will then request the name of the firmware file and the COM port to be used
before going on to update the firmware in the instrument. Since this is not batch mode,
the user is asked whether or not another instrument is to be updated each time an
instrument is completed.
If any errors are detected in establishing communication with the 2635A or updating the
firmware in the instrument, descriptive error messages will be printed to the PC console
before the program exits. Make sure that the PC is connected to the 2635A as previously
described, and that the 2635A communication parameters have been set correctly.
