Hi docbrown,

Data_out (Acknowledge) is pin 10. Data_in is pin 2. Vdd_enable is pin 4. Vpp_enable is pin 5, and clock is pin 3. Signal ground are from pins 18 to 25. Attached is a pinout of the D25. Hope this will help.

Regards

Shum

Shum,

I will re-wire this burner again. No wonder the red light is always on  >:(  Looking at the connector in the diagram, it seems like its facing back which is the conductor side, but not the pin side.

thanks… ;D ;D
