Mitsubishi cable pinouts

[jonnie75]

Does anyone happen to know the exact cable pinout for connecting a laptop to a Mitsubishi Melsec FX-64MG plc. I was told by one of Mitsubishi's engineers that a special SC-09 cable was the only way that communications could be established at a price of $195.00. Any feed back from someone with any experience in this area would greatly be appreciated.

[Eric Nelson]

OK, let's see how (if?) attachments work in the new forum... utoh

Attached (maybe) is the schematic for the SC-09 cable

Now you can decide if it's worth $195.00 :D -Eric

[Eric Nelson]

Gee, that worked quite well!

Thanks for the schematic Eric. It looks as if it might just be easier to purchase one. It does appear as if a 4 channel 232/422 converter would do the trick. Then you could communicate with a FX but you would need the mini connnector to communicate with everything else (FX0). Don't think it is worth all of the hassle.

I can get the connector only for this plc FXON for about $10.00 and will orde it in a while, when i find out more info about th type of data or format this plc uses, maybe 422 or 485. I have both types of pc card over here, maybe a program coming to. Let type to get things working.

[adyro]

they use rs 422

I havent tried these pinouts personally. Let us know if one works for you.

I don't know of the specific processor you are referring to, but here is a decent alternative to purchasing the SC-09 cable for the FX series processor. They also offer other cables for the A-series proc. http://shop.mrplc.com/view_product.php?product=cable-mitsufxseries

Dear Eric...
to provide us the sc-09 cable pinout was a good action, but I would like to know what integrated circuit I can use to assebly the cable. If you can help, we´ll very greatfull.
regards

[Contr_Conn]

IC's are MAX202E on RS232 side and 75179B (2 pcs) on RS422
Capacitors for MAX202 are not shown

[sergeylima]

Now a will can assembly this cable!! You saved my day

Thank´s my friend!!

I finally got an option to work, First B&B Electronics sells a REVERSE 232-422 converter (Model 422CFCR) AC adapter not included - but needed!

Use a standard RS232 cable for the PC, with an off the shelf DB-9 to DB25 adapter.

Then I had to make a DB25 to DB25 adapter cable to match the pinouts of each (sorry I can't find my notes now, but it only took me a few minutes to figure out & make the cable.)

I didn't use it but I also made the DB25 to 8 pin mini DIN for the newer PLC's.

[scottmurphy]

The only thing for me, is that I cannot quite see the pinout no's on the opposite side of the SC-02.

[scottmurphy]

If Eric reads this, could you possible email me that schematic directly, or tell me where i can get a copy of it, I want to be exactly sure of the pinouts, and I can't view them very well thats all. or if not, if you still have it, could you state the pinouts from top to botton for each connection for verification for me please?

[Eric Nelson]

Over at mrplc.com, Paul Miller gave THIS (http://www.btinternet.com/~paul416/PLC/sc09.jpg) link to a drawing that's a bit clearer. Don't let Windows resize it for you... ;)

[bigjoe]

does the sc-09 programming cable works for FX0-20MR mitsubishi plc? I download the schematic but I do not understand some of it because it is a little distorted. Any one has a clearer version? thanks

[bigjoe]

IC's are MAX202E on RS232 side and 75179B (2 pcs) on RS422
Capacitors for MAX202 are not shown

what do you mean by capacitors are not shown for max202? Do you mean that they are not to be use?

[jvdcande]

BigJoe,

generally 'not shown' just means not shown, but definitely needed. It's a well known practice to keep schematics from being overloaded.

Bob1371,

that file is very good, except for the DN3000 part. Unless you have that gimmick available, the cable schematics don't do any good.

Kind regards,

thanks for the reply. Do you know where can i find a more detailed schematic of sc-09 cable? or that can work for fx0 and medoc? are there other substitute for 75179B and max202? or where can i find data sheets for those chips?

regards

[Nigel Betteridge]

bigjoe,

I have an original of the SC-09 schematic that was posted earlier in this thread. I have scanned it as a 500K (ish) jpeg, and would be happy to email it to you. (It is completely legible). Send me a private message with your email address and I'll send it to you. The SC-09 can be used with the whole FX family.

Regards,
Nigel

Hi Eric,
Can you give me more detail for beijers scematic? I would like to make it but to rewiring the Ic i still confuses. Please email me at ucox_electric@yahoo.com
Thankyou.

[and123]

hi nigel
would be greatfull if you could post me a jpeg, copy of sc-09 schematic of fx, all new to me and would like to give it a try without spending too much
thanx
andy

[Nigel Betteridge]

Andy, send me a private message with your email address, and I will send you the jpeg. Sorry I didn't get this sooner, I don't read my mail every day. Also, just to warn you, I am away from Thursday till next Tuesday.

Regards,
Nigel

Hi All.,

please reffer my file at this forum (RS232_RS422_Mitsubishi).
the wiring diagram for programming Mitsubishi PLC to PC.

[and123]

hi ady
the u3 chip in the circuit u send me, would u know if its the MAX232 OR MAX202
ANDY

[ady_kurniawan]

Hi Andy.,

ofcourse U can use the MAX202 that upgrading part from MAX232 with improved ESD and 0.1 microfarad charge capacitor is available.

Thank you very very much for the muddy scans of the cable schematic; totally adequate for anyone who takes the trouble to read the advertorial information Maxim et al put out and/or understand OpAmps to any degree.

I cracked up laughing and fell on the floor looking at that stupid 200p protocol manual and the 1/2W resistor specs; is there some school of thought that suggests ninja PLC programmers would just tap the serial program in after passing the HAM Ops keying test? SE HABLA RS232!

I am somewhat inclined to whack this human problem (un***y cable diagrams) with my vector graphics toolkit; let me know what all ye had in mind in private e-mail (or publicly here, and let the admins sort it out.) I'll let you know how to put it together with saltwater if you have to be RoHS compliant, whatever! (Lead-free solder is a little irksome, after all.)

but I wanted to express for spiders that this is about SC09 or SC-09 cables, the official Mitsubishi cable meant to program their FX0 (FXo, FX(0), please tell me it's totally obvious from looking around at a Mitsubishi plant or Bishitown (LOL).) Any FX series controller, really.

[rajsiyer]

Hi geek fellas...


2 years or so, ago I'd posted on Mrplc.com a cable that I'd made that time & which I still have. Have to inform you all that this still works with Medoc. In case you need to use it with FXGPWin/Developer GX, ensure that you short pins 7 & 8 on your PC side 9 pin D connector.

All told, these days laptops don't come with a serial port. An usb/serial converter may be experimented with. This I've still not attempted but will like hearing form

[vicenterf]

Please could you send to my address the pinout of the cable sc09 from mitsubishi plc controlers

many thanks in advance, let me to know where I can found the communicating software, I have an old fx32mr
many thanks in advance, my address is vicenterf@yahoo.com

Dear friend:

Could you please sent the complete pinout of the cable sc09 from mitsubishi plc, I have an old fx-32mr and also I looking for a communication software.
Many thanks in advance
