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? |

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. |
