I have a ScanExpress 12000P. I'm pretty sure there isn't a chip in the
cable. The low-level communication protocol is the same as for the
600 III EP Plus but it seems to use different registers. It uses
different methods to control the motor and lamp. I have disassembled the
VxD and wrote some simple code to switch the lamp on/off, detect
whether
the cover is up/down, move the scanning head back to its home position
and check if the scanning head is in its home position.
I tried to contact Mustek in Taiwan but I have never received a reply.
I had a look a Jeff's backend and therre's a lot of work there. I
imagine
the 1505 ASIC used in the SE12000P works in a similar way so I'll study
the
musteka4s2 backend to see if I can translate stepper motor control, etc
to
the SE12000P.
Jeff, is it possible to get contact details for the Software Manager at
Mustek you mention on your page? If we can get information on the
SE12000P
from Mustek it should be a relatively simple matter to extend the
musteka4s2
backend.
