it's easy to build, just seach for a good diagram..........

Hello

I have a Casio Graph 100 + with the cable of an older program (FX Interface)

I use CasioCom !

I coorectcly backup Casio->PC !

it is saved in a file it is ok

I send this backup Casio said me it is ok !

but when i go to the program list it is empty !!!

I don't have flash programm ... just simple prgrams edited with my Casio !!

an idea of the problem .... ???

[rjstephens]

what pc program r u using. if you're using fa122, you might want to try fa123. if your using fa123, you might like to try the FXI and Cat patch from Libthium, downloadable from:

What voltages do you mean?
Do you mean the voltages between the ground and the middle and tip from the calculator connector, or the voltages between the ground from the 78L05 and the middle and tip from the calculator connector?

Thanx anyway...

[superna]

Okay Ronan, i'm also on mac so X man !
you can't connect it but if you have Virtual Pc installed, you'll just have to connect your serial cable to your mac with an usb to serial cable (i have one) and launch VPC to communicate with it !
It's simple !
To have VPC : http://www.na-prod.c...les/vpc-mac.sit

Another problem, just contact me by email at superna AT na-prod.com

with pleasure

(Do youu have Toast Titanium for mac os x ?)

[superna]

it's about 5V (volt)
look at my doc about afx2 comm port :

(in english !)

[epaloco]

Yes ..please tell me that voltages...

=)

[Bj2c]

like i said before , i build my cable in a protoboard , i use 4.7uf capacitors , i read that it`s safe `, but you can find some cheap ones on e-bay , but if you dont casicorner has a seccion of links only for cables

[jantje]

I've collected the following voltages:

Between Ground from the IC (pin 2 from the 78L05) and:
- Middle stereo connector: 3.53 volt
- Tip stereo connector: 2.52 volt

Between ground from the stereo connector and:
- Middle stereo connector: 3.53 volt
- Tip stereo connector: 1.47 volt.

Maybe these voltages will tell you something about my cable and maybe you can see what's wrong with it.

[kbumbaz]

i am using CasioCom ... an idea of the issue for my girlfriend problem ???

[Brazzucko]

From all the non-CASIO pc link software, I can only use the FlashCom, all other programs crashes?..

[Brazzucko]

I really don?t know why?.

[CrimsonCasio]

Brazzucko EDIT your posts, that last bit could have been one post, not 2.

[Brazzucko]

Sorry, this will not happen again....

[CrimsonCasio]

Its fine, just people don't want to log on to see new posts and only find something like that, also it can seem as if you are doing it just to increase your post count.

[epaloco]

Well lokking at the voltages you wrotte I?ll tell you that your problem is that you don?t have enough power,you may try adding an extra power supply for example a 9v batterie to the input of the L7805 butPLEASE BE AWARE NOT CONNECT BOTH THE BATTERIE AND THE SERIAL PORT ...!!!YOU COULD SERIOUSLY DAMAGE YOUR COMPUTER!

You need at least 3.0 3.2 volts in your calc connector so this will work!
As far as I read you are having enough voltage at your middle ,thats the transmitt part of your calc but you lack of power at the RECEIVE that?s were you have 1.47 volts...you may need to increase that to receive something!!!

Before adding an extra batterie try using smaller caps..usually they drain less current ....!!!remember that the serial port is not designed to support max232 etc,..so we are overcharging the rs232 interface...

Please let me know what happened!wish you good luck!
=)

P.S.:use 1.0uF caps they are the less supported by max232(at least by Texas instruments semiconductors).

[epaloco]

try with 1.0uF caps ..try to obtain more than 3.5 volts in both the tip and the middle part of your calc connector,it should be working if you try this...

Hi. My name is atomc

I have been reading this forum for quite some time, and have successfully built myself a PC link cable from the diagram on casiocorner.

I own a Toshiba e740 Pocket PC, and I am curious. Is there any way to get it to communicate with a Casio calculator (I own the CFX9850G)?

I have two problems:1. connection of cable to pocket pc (i have an expansion pack that features a USB port - could this help?) and 2. software (i have a dos emulator installed, that might be helpful)

any help appreciated.

[CrimsonCasio]

I have a Toshiba e310 and as far as I know you cant connect it to a Calc for two reasons: first there is no PPC application for transfer, and second because there is no port to connect to... now you say you have a USB add-on, it is possible that you could get something to convert that to a serial port and then connect it to the calc, but you would still need to have a program that would comunicate between the two.

[Atomic]

it is possible to get a DOS emulator for pocketPC.

Are there any DOS programs that can communicate with Casio?

[rjstephens]

Link-Up by wallace wadge, but i had a lot of trouble getting it to work.

--edit--
it can be downloaded from:
http://perso.wanadoo...cutilities.html

[XYZ]

Don't those things have iR serial ports or anything?? Why, may I ask, do you want to connect it to your pocket pc anyway? UNless perhaps you travel a lot and want to upload progs downloaded from the net on your PPC??
INteresting idea

[CrimsonCasio]

it could be used as a handy memory/storage area.

[Netforce]

You must also keep the 'handshaking' in mind...
The receiving calculator expects a 0x16 as handshake, but (much) pc's and pocketpc's will send a 0x15 or another handshake. It's possible this will occurs a problem.

[Atomic]

well i have a deal where people pay me to put games on their calcs. the problem is that very few people let me take their calcs home, so i have to use the school computers, and i have to be careful then because i have to make sure i delete all the files when i'm done. if i don't, the admins will find the exes, find the games, find what they are for and bust me. I have already got caut once. I lost my computer access for the rest of the month. (it was the 21st anyway, so it wasn't any big dea)

anyway, it would be nice to be able to do it from my pocket pc, because that would be risk-free. I WISH I had a laptop. I COULD have had a laptop, but the pocketPC was more portable, so i chose it. that was before i got my calc though.

[Netforce]

Hehe, a good business!
You have to spend one time some money for the cable parts, and that's it. Very clever

[Atomic]

yeh i've already made back the cost of the cable.

on the topic of IR, yes pocketPCs DO have ir ports, but i am unable to find an IR adapter that plugs into the PERIPHERAL rather tha the COMPUTER (or in my case PocketPC)

[Bj2c]

i still think it`s safe to build your own cable
, price 5 $us , it`s cheap

[jantje]

O.K Thankzz

I'm gonna try it!!!

[Casto Productions]

I attempted to build my own, but I had trouble with it, couldn't get it to work after soldering it. I really don't remember what diagram I was following, so maybe I just had false information. But now my original cfx-9850g broke, so I wouldn't have a way to test it if I built it now. Could someone please send me a actual working diagram that has been tested?

[Bj2c]

first i didn`t sold my cable before a test it , i don`t know much about electronics , i build my in a protoboard first , i tested and it works fine , then i sold it , the diagrams
http://www.hw-server...ml#Construction

i hope it works for you

[Casto Productions]

Anyone know if there is a USB connection from computer to casio calc available yet? I know they have had one for the TI's for some time now.

[kbumbaz]

hello all !!!
tanks you for you answer

sorry I was on holidays !!!


tanks U I will try !

[guillearg]

I have a CASIO SF 4300 BK diary, and I need someone to tell me how to make my own pclink cable for it.
Thanks.

[Brazzucko]

Well for what I have see the number of new topics related about the PC Link Cables has one drastic reduction, but the number of posts are the same?? very very big?....

[jantje]

Who knows a website where I can find a print-layout for the FA-122 cable. Not for the original cable, but for the one with the MAX 232.

[Espa?ol]

casiocorner , easy

[jantje]

no, I mean a print-design for the schematic with the MAX 232. (The second one one casiocorner).
On casiocorner is only a print-design for the original cable, but not for the cable with the MAX.
Who knows a site were I can find it?


Thanx.

[jantje]

Anyone know if there is a USB connection from computer to casio calc available yet?  I know they have had one for the TI's for some time now.

Yes there's an adapter. Look at the normal forum under 'Very usefull adapter' and you will find any informations about it.

[BiTwhise]

I think he means a pure USB cable, not a serial->usb converter
