Link Cable FAQ
Posted 28 March 2003 - 07:05 PM
Now the question is: when I open the FA 123 software, (after linking the cable to PC and turning on either PC and calc), is there any way to understand if the PC "sees" the calculator?? My PC does not absolutely see calculator as a new peripheral....
I just set COM1 (I also tried with COM2) and the type of calc, but when I try to send data in both ways I just see error messages either from calculator and from PC.
I tried two different cables (bought from an official CASIO reseller!!), with two different fx7450, on three different computers with two different windows operative systems (win 98 & win XP).....should I perhaps use win 95 to make the whole system work???
I don't know what else I could try...
Please help me!!!!!

I begin thinking it could be a problem from the cable...even if this is not a hand-mede cable!! it has been bought in a shop, and already changed one time with another one!!!
I don't know what to think.....

have you set the calculator model from afx 2.0 to fx 7400?

Maybe someone can send you that part?
And there elektronic-shop's where you can buy online. (Like Conrad) www.conrad.com
I think they deliver over the whole world.
Maybe you can try that.

Or with the cable..........
Is it possible to open the cable?
Maybe there's something loose in it.
Or something inside make short-circuit.

Well i would say try around with com ports. there is no change between windows 95 and 98, so it wouldnt help to try this, and xp and 2000 is the same nt system too.
mhhh sucks. simprobe he bought from the official casio reseller, so i dont think they sell ti cables there.
have you set the calc on receive when transferring to it?
no the pc doesnt see the calc as a new peripheral, thats normal.

also did u try a different model calc?
btw I use homemade cable, cfx9850gb+ and sony laptop w/win xp

I begin thinking he has got in his shop a serie of nonfunctioning cables!!!....in effect, they are not produced by casio, but by a deutch producer who sells them with the casio official logo....and with casio permission I presume!!!
boh boh boh....no more ideas....
Thanks to all who tried to help me!!

why don't you try a homemade cable. there not that hard to make. (I did it, how hard can it be?)

My calculator keeps waiting the data and it will continue like this for 3 days if I allow it...
I triyed fa123 software and the common max232 circuit with the 7805 and the 5 caps,2 diods....
here is the info that i could tell you...i meassured th voltage between ground and the middle tip,ground and the tip and the results were this....
2.98 volts between ground and tip
4.5 volts between ground and middle
The diodes meassured -(minus)9.5 volts at the anod.
i get an error mensage or sometimes it keeps waiting and it says octetc received 0% and it doesn?t move....
I didn?t short the pin 4 and 6 with 1 as its recomended for a 9 pin serial socket.
What are the meassures i could test to know if I?ve made my circuit correct?
Please any information will be very usefull!
Thanks a lot

I think you had to do that, because the FA123 software needs it.
(A website said so).
Maybe you can try that.
Or try it with another link software (search the web).
But maybe there's something wrong with the circuit.
Do all caps have the same value? Thats necessarely.
Did you use a socket for the MAX. Maybe you've solder them to hot.
Try it with another PC and calc.
Are the settings for the com port right?
Maybe you can try these things.

thanks for your support...and by the way...
where could i download the version 2 o CAS???(the one that afx plus has??
Posted 02 April 2003 - 08:07 PM
CASIO didn't release it yet, though we asked them many times.
The version on their site (which is called CAS2) lacks the matrix, list and vector symbolic manipulations.

and it is not possible to send through a USB by fa-122 / fa-123
BTW. It's dangerous to use other cables because I don't know
if there is a voltage changer in it and if not you may destroy your calc.

and if you want to buy a cable i can suggest you to search e-bay.
They have the cheapest ones. (You should only build one yourself if
you are VERY expirienced with electronics. You may destroy your calc
if you make it wrongly! See the other threats for this)

Search casio link cable on e-bay (not "sb-87")
Posted 07 April 2003 - 12:28 PM
