Warning .. this data is not a realy docummentation for primax hardware.
ALL this is only my suppose.
Comments to
All this is obtained from logs of trafic betwen scanner and windows
driver. I use WIN 3.11 driver files
Communication betven scanner and computer start with wake_up with F9
parameter. Next wake_up with A9 and one or more epp write or read
operation. Finaly slepp up with A0 parameter is sendet to scanner.
Many thanks to Gustaf Kröling for correction in this
file.
