Service Manual

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:

/BExecute 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.
