Hello,

    I've made a little equipment that sends DMX (RS-485) signals. It works
very well on my lab, but when using it with other clients equipments, it
eventually dies, or starts to work erractically.

    When I have the unit returned, its program memory is slightly changed. I
mean, some words are changed and some program memory EEPROM locations that
was unprogrammed (3FFF)when the unit left my lab, not have some dirties.

    Have anyone seems something like this? I'm using a PIC16F873 and a 75176
DMX driver on the output stage.

    Best regards,

    Brusque
