• W86F3448D • • • DIP36S purpose (It is common with production discontinuance model
(LC86F3448A / LC86F3548A) )
• W86F3448M • • • MFP36SDJ purpose (It is common with production discontinuance model
(LC86F3448A/ LC86F3548A) )
When using the conversion board, all of the jumper SW must be set to the OFF position.
If set to the ON position, read/write operations will not perform correctly.
