Hi again.

I borrowed an CFX-9850GB PLUS (black model) and with this when I try to send anything to the computer I also get a "Transmit ERROR". In the Hyper Terminal appears this:

When trying to send anything to the calculator I get "Receive ERROR!".

I've checked the circuit and I didn't find any mistake.

Any idea of what's wrong?

[Andy.Davies]

if your cable has passed the tests that are on my site, then there could be a faulty ground line on the jack plug of your cable. check that it is properly connected to PIN 5 of the Serial port, PIN 15 of the MAX232 and PIN 2 of the 78L05.

hope this helps

Is this the right cable for Casio CFX-9850GC plus?


I'm thinking of buying it.

[huhn_m]

I'm not sure but I don't think so.

[Crazio]

I got fx-9860 calculator with unit-to-unit cable and an USB. The USB fits perfectly between computer and the calculator, but the computer doesn?t recognize the calculator and I didn?t get any kind of installation CD. Can anyone help me out with this one, so I can get the games I?ve modded to Int3rnet.

[huhn_m]

You need the FA-124 transfer software (that should have come with the cable).

You can download it from the casio website or google for it

[kucalc]

Does anyone have a spare calculator-to-computer serial(not USB) cable they are not using anymore? I really need one.

[caspro]

I don't have a spare, but I've been looking at where to buy cheap cables.

On this website:
http://www.pfranc.com/pclink/a.shtml
it says that the sb-155 cable for QV cameras is the same as the serial calculator cable.

However I just bought an sb-155 cable (?3.99 +?2.99pp from sales AT abcproducts.co.uk)
to see if this is true, and upon testing it, found that it doesn't work.
I tested it with both FX-Interface and FA-123: neither work with this cable.

Conclusion:

a. the sb-155 is not the same as the casio calculator cable ?

b. the cable is broken ?

c. the cable is not a genuine sb-155 ?

My guess would be a.

I also have the cable that was supplied with FX-Interface and that works just fine
and with the fxi&cat patch, FA-123 works with the FX-Interface cable,
so there is nothing wrong with the calculator or the computer.

[kucalc]

I don't have a spare, but I've been looking at where to buy cheap cables.

The only place in the U.S.A. where I can find a place to buy the cable: http://my.casio.com/.....=FA-123Serial

But it's $80!?!? Oh, well...

[caspro]

After looking around this is what turned up:

The cable that comes with FX-Link Kit is the same as the sb-87.
Fx-Link Kit is available from dynatech.de for 24.95euros
(even though they sell sb-87 cable on their own for twice the price, which is kind of crazy)

On ebay.de, VL-Kabel is selling FX-Interface compatible cables (need to apply the fxi&cat patch to use FA-123)
for buy-it-now 13.49 euros or you can make a bid. (PayPal accepted)
ebay.de

Charlie Watson is no longer selling calc-computer cables.

here is the guide on my website, it also includes testing procedures for your cable: http://www.stormbase...index.php?id=20

here is the guide on my website, it also includes testing procedures for your cable: http://www.stormbase...index.php?id=20

there is a common error when building cables; because some 78L05 has different pin distribution, so any people that are involved with linkcable building must have some care with that (for example, in my country, when i buyed one 78L05 i failed the first time because its pin distribution was different that one 78L05 from Europe,or USA )
i hope this info could help somebody.

Are there any more current places that sell link cables for a decent price? I don't have any electronics knowledge, but I don't have enough money to buy the pc link cable from casio. I'm so sick of typing in programs.

[huhn_m]

Welcome to the forum
you either need the correct link cable type for your calculator to connect it to a pc or you must type it in by hand.

[NSUSER]

Hello to everyone. I am new in the forum. I would like to buy a USB-cable in order to connect algebra fx 2.0 plus with my pc. I am between yellow FX-Interface professional (fxi-Format) and FX-Link-Kit (pg-Format).I would like to ask if I would have a problem to use the program of fx-link-kit with the cable of fx-interface. And what is the difference between fxi and pg files?

I think i know what you are talking about but the pins are the same everywhere.
If you buy the large version of the 7805 the pins are in one way if you buy the small one the pins will be in another way but that never changes from country to country

[djrose]

Hope this is a simple question:

Does Andy's serial cable (http://www.stormbase...ndex.php->id=20) work with the FX-9860

Thanks in advance.

Edit:
I have just noticed from the FxReverse Projects Documentation that the FX09860 uses standard/typical voltage levels (the document mentions 0V and +4.2V). It is the electrical parameters that are my biggest concern and have no worries about the software communication protocol.

Confirmation would still be appreciated.

[SimLo]

The voltage level of the FX9860G's 3Pin is 0V and about 4V.
I use an adapter based on the schematics mentioned above to connect a FX9860G with the PC-serial interface.
But I implemented an external power supply connector, because I want to connect any serial device.
And I used a MAX202.

[djrose]

Many thanks for the confirmation.

My adapter also has an external power supply (PP3).

I built it myself (originally) for my FX-2 so I could connect to other devices that only have Tx, Rx and Gnd.

[macdad64]

hey Andy does the instruction for the PC-Link cable that you showed, does it work with CFX9800G? Cuz i have been looking every where and either its cheap but its the wrong cable or its expensive and its the right cable. And i got scammed on Ebay for it(then sent me a completly different cable and i got PO'd)


but if you have a link for a link Cable at a good price for the CFX9800G, then please send it.

[Predator Mario]

Is installing the Casio fx-9860G drivers impossible because none of the FA-"something" installers doesn't work and I can't find the drivers anywhere?

It's pretty stupid that you get a cd with your calculator and the installer on it doesn't work and when you download the installer on the internet and it doesn't work.

[RadioChris]

Hi there , i am new to this forum and this first post. Wow, i hope i am not too late to make a comment on this topic. As i am ready to begin on making a cable for my casio CFX-9850GB Plus. The only problem is i dont know where to start?.

Are the schematics posted on this website working correctly?. Has anybody tested them on both receiving and transmiting?.

I have looked forward on this thread and somebody mentioned earlier there were some problems with transmiting from PC to the casio (using the Max232) (communication error in transmition / receive).

i tried to make a cable and it doesnt work.
i didnt everything connected everything correctly and it doesnt work,.
i tried to make this one http://www.casiocorn...a-122_small.jpg


i plug in the cable to my comp and try to go to receive on my calculator my calc say "receive error"

whats wrong?

I made it too, and transmitting from calculator works fine, but receiving doesn't work. I see if I can solve the problem. I'll let you know if I success.

Hello again. I found this page, that could help. I haven't read it yet, but it talks about the same problem and about a solve to it. Let's see....

http://www.abc.se/~m...io/linknote.txt

See you soon.

Is this related with the following schematics?, has this issue been fixed ?

http://www.casiocorn...bles/Univer.jpg or
http://hw.cz/Teorie-...9850G-a-PC.html )

is it consistent with Maitre Kiwi's version? (I had been unable to look Andy's serial cable guidelines, seem to be turned off/archived? http://www.stormbase...ndex.php->id=20)

I have read, all post and I give you a cable who work fine ! I have built it for me, friends, etc... and no probs !

check here :

edit : link too old


see now :





i think with this type of schematic you can put it in a box, but you must work again it a little (for the format)

(seen here : http://www.casiocalc...amp;#entry31823 )

Other person stated the 9V battery should be removed or jumpered between pins 1 to 3. I know some about basic electronics. (Is this safe?). Whatever.

OK, got it working (if anybody cares...). You must remove the 78L05 and add a wire from it's leg 1 to leg 3 if you know what I mean. What you call it? A jumper? You can't use the 9V power supply anymore, but the cable starts working. And add one 1N4148 diode to MAX232's leg 13 so that the current can flow from db-9 to max232 (the "ring" of the diode is towards MAX232).

Hope somebody understands... :-P

Ok, got schematics of my cable. url is: http://sponge.leesio.../CasioCable.jpg

Zan

It has been hard for me to track all these messages as many links dating from pre 2003 era have already shut down.

I really need help on this matter before to begin on it.

As i dont want to blown the max232 accidentally or chips inside the calculator/computer.
Any assistance on such matter would be appreciated.

[RadioChris]

Hi guys.

Finally i managed to build a cable that does work. At least for my casio CFX9850 GB Plus (I think for the series it will work as fine like it did to me).

The schematics i used are based in the original design made by Lawrence Henry Berg, you can see the parts used in Larry's website and patent at http://www.pfranc.co...link/myidea.htm

I made some changes in the patent as i could not find the mosfet transistor p channel ZVP3360 instead i used the IRF9610 (i think its easier to find than the zvp3360). I added a couple of leds so you can see actually the communication is happening between the calculator and the pc.
You can see initial stages of my experimentation at : (Sorry pictures are not in the right order)



If anyone is interested on my design you can ask me and i will post it. (Although i am still working on it).

I had some problems working with MAX232 to made the cable and i get the same issues previous users reported.

It has to be noted that i found another design for these cables in a german language site: http://www.lamepage....asio/index.html (i haven't tested the circuit but i believe it would work too).

Since Larry's design was made specifically for the Casio's and because it doesnt require any special chip that might be not available everywhere (particulary in europe, as i read previously in this thread). Maybe this version can be a good replacement for those interested keep trying with max232.

I hope this would help anyone interested on the topic.

Hi, I have Casio fx-9750gii and cable for PC. But don't have sofware and drivers. So how I can upload files on casio fx-9750gii across that cable?
Does anybody have software for casio fx-9750gii to give me ?

[HabanR]

Hello I have a Casio 9860GR
I´m trying to install FA-124 version 2.0 in a windows vista OS and when I axecute the setup wizard, after several steps when the installation bar is complete this massage comes out:
"The wizard was interrupted before CASIO FA-124 could be completely installed.
Your system has not been modyfied. To complete instalation at another time, please run setup again." I´ve tryed many times and I,ve restartede the computrer whithout any change in the procedure.
Do you know what coud be the problem?.

You probably use 64bit version of your operating system. Casio doesn't have and even doesn't announced development driver for 64 bit operating systems...

Hey,

Radiochris: If you are still there (probably not) after one year since your last post, but anyway I'll give it a shot. I would like your design. But i would rather buy a cable from you at a cheap price if that is possible. I dont have time nor motivation to build my own, but if that is the only option i would very much like the schematics.

I own a Casio CFX-9850G Plus as well, i wanted to try and connect it to PC and try transfer data between. I wanted to try code assembler programs for it since some guy hacked the calculator and found out most of the instruction-opcodes, but since the calculator is so old and it only has RS232-communication transfering theres a problem of course. My laptop dont have serial or com-connector output, only USB. But i searched the net and found the cable if i want buy it, but its so damn expensice. Its called PC-Link cable and some british/english- company is still selling it. also must buy a RS232 to USB interface. I dont know if it will work in Vista either, thats why i ask if someone has allready tried this?? and got it to work??

Also i read somewhere that the transmissios-speed has to be somewhere around 9600 bytes/sec, i wonder how that'll work on vista. I wonder if i have to code a software-tool for myself to handle this transmission. since i know C++ i dont think that should be much of a problem. The problem is the hardware and if that would work via USB on modern operating systems like Vista.

Unfortunatelly, i think the best option it is to use the RS232 Casio cable + the RS232 to USB.

These converter cables are tricky, some of them. I have one at home. I haven't used in years. I will give it a try this weekend, and i will post pictures about it. Maybe it can help people to build their casio cables, as the preceding project was quite a year old.

I have to say, that the quickest solution for this problem it is to buy the original CASIO cable, and it is NOT so expensive. Are 18 US$ expensive?. Ok, anyways. you can build one for yourself at half the price.

The combination from casio + RS-232 to USB and the FA-122 or FA-123 software it is just fine.

On Casio Page tells FA-123 software can work with Windows® 3.1/Windows® 95/Windows® 98.

I have Windows XP at home so, it works fine. I haven't tested on Windows Vista, but i think it will work fine too.

Very nice Chris,
Hopefully ill buy myself a cable in near future.

[kepak]

I just bought a calculator Casio fx-9750G for 7 PLN (about $ 2). I want to buy a cable to the computer. Cable FA-122 is compatible, but I can not get it. I found a cable SB-87 for sale on. Can I use it with this calculator?
What software can be used to send programs (i got windows 7 x64)?
