Sometimes, when writing, the error information is given from PC, show the IC isn
’t place correct, then you can
Verify the connection as below
Draw out the power line and USB line from MP5S
,
and open the MP5S
Note: Every transfer board
,
the writing pins of M5S are fixed
,
on J2.
Check the connection of writing pins on J2 with corresponding pins on IC with multi-meter. If they short ,then
the connection is OK; Otherwise find the reason and solve it. Please refer our IC specs to know the pins of IC

Note: SNC32P &SNC86P have no this pin, and you needn
’t to check it
In addition, if there have R1 resistor on transfer board, please check this resister connected OK or not. The
transfer boards of SNC27P have this resistor and SNC32P&SNC86P have no.
