Rohde & Schwarz Signal Gerator SML-01, (FIXED)

<< < (8/10) > >>

Hello to everyone!
I have the SML01 that does not respond to keyboard but responds to the rotary knob. The keyboard matrix is working as I see it transmits pulses to PERIF2 chip.  I suppose it is a problem with flash firmware.
I see no way to update firmware through RS-232 as there is need to press key "5" before update process but there is no response to keypress.
Does anyone have the flash dumps from SML-01-02-03 or SMV-03?
I would appreciate for help.

Hi, Spirex!
Thanks a lot for dumps!
What programmer did You use for that?
Were there nuances with reading/writing the chips?
Is 24645 also from this SML-01?

Spirex:
Hi!
Programmer TL866A with programming panels tsop-48.
There were no programming problems.

I just do not remember where installed on the board EEPROM X24645P

If the keyboard does not work, I think you need to enter the programming mode through the digital interface on the back of the generator using the control commands described in the service manual.

Ok. I was thinking about it to enter the programming mode through the GPIB. But have not GPIB adpter yet.
Thanks.
