[hacko12]

Hi all, from yesterday my tacho pro 07/2008 have reading problem for 93cxx eeprom's, when i connect cable with 93cxx adapter and check connection from cable to adapter everything is fine but when i solder some 93cxx chip and try to read with tacho pro 2008/07ver. not working. Anyone help me what is the problem?

Hi Hacko12, try this: read an eeprom 24cxx, if not reading, you need to replace chip 74HC541/74HCT541.

Regards.
