lindbergh force feedback question

[devtty0]

Hey,

I upgraded to a lindbergh after my chihiro failed, but it wont boot OR2 without a drive board connected.. this page: http://assemblergames.com/l/threads/sega-lindbergh-external-drive-recommendations.54131/

says you can use a rs232 to midi converter to connect the existing 838-14174 drive board, but the 'midi' connectors i've found online are just music ones

the pinouts for 838-14174 have TXD+, TXD-, RXD+, RXD- and 'SG' (ground?) .. do these correspond to a specific protocol, or are they chihiro specific?

thanks!

answering my own question maybe, but is it RS422?

 

[Outrun2]

Haven't got a Lindbergh setup but I remember seeing an RS-232 to RS-422 breakout cable somewhere online..

 

[devtty0]

cheers yeah, theres this one, 838-14502-01, which is described as the serial board:
http://triplemoonstar.brinkster.net/theshed/default.asp?stockid=168955558

and heres a 422 board for that??

I've ordered a rs232 to rs422 breakout, and will update how I get on

 

[devtty0]

just tried the RS422 breakout board, and on one of the configurations, instead of the 'drive board not connected' error, I get the error:

drive board : (1) original point error

.. has anyone seen this before?

thanks

I had the same error message on mine a while back. I would have to check my Cab in a mo to see but if I rem correctly it was a bad connection on one of the Looms running down the side of the Cab to the Servo board, so I wired it directly and fine now

 

[devtty0]

cheers - I didnt actually have any of the wires connecting the board to the steering connected, but I've been through them now, and wired them up, however still get the same error.

.. looks like I may need the 838-14502-01 board

 

[bbz149]

Yeah you have to have those connected or it will fail the calibration! Also you def need a 838-14502-01 Servo board! Not cheap though and Andy had some new ones for £300 on his site. Let me know if you find any Servo boards for a good price as I'd like another one

 

[devtty0]

so .. an update on this: I bought a 838-14502-01 Servo board - and I'm still getting the

drive board : (1) original point error

from speaking to Andy, I may have bought a model 3 dash from a scud racer, and there is another board which is required for this .. so I may not be able to interface with the 838-14502-01 Servo board

does anyone know which board this is? (i've seen the other thread, and seen discussions about LED error codes etc..

thanks

I can't help with your last question, but the chihiro FF board indeed uses a midi interface. This basically uses some opto isolators between the 2 connected devices. The midi music interface uses the same type of coupling. So, TX needs to be able to drive the led of an opto, and rx is just the led of the receiving opto. midi uses a rather strange baudrate. It would suprise me that the lindbergh uses that same baudrate when it's just RS232. Maybe chihiro is using a normal baudrate as well.

 

[obcd]

Rereading everything, I am a bit confused. I thought you were modifying an outrun 2 from chihiro to lindbergh. How does the model 3 dash from scud fits in that picture?

Do you know if the SPG Mecha/Encoder is 100%? And just double check the encoder loom wiring from the motor board to the SPG encoder on the motor - IIRC Scud has an extra pin wiring there.

 

[devtty0]

thanks for the reply's .. I've no way of verifying the SPG Mecha/Encoder .. I bought the dash of a member on here.

I did have a look about for a scud wiring diagram - plenty of manuals, but they seem to be missing the wiring!

and obcd: I bought a initial D empty shell - wired it up, bought a model 3 dash to replace the large wheel (like the one here http://www.ukvac.co.uk/forum/fs-sega-driver-parts-shifters-boards-plastics_topic337255.html) bought a chihiro - that broke, bought a lindbergh - that didnt work with the drive board, bought a drive board .. and that may not work with the dash I have, as the motor encoder is different for scud race!

.. the fun never ends

 

[obcd]

My mistake. I thought you had a working outrun 2 on which the chihiro suddenly failed.

The fun indeed never ends. Problem is the costs neither.

 

[obcd]

If your dash is scud race, it had a force feedback (servo) drive board that had a parallel interface to the game board. It's incompatible with chihiro (which uses midi interface) and with lindbergh (which uses serial) I have no idea what would be the best solution to solve those incompatibilities.

Maybe the motor encoder can be made compatible with the later servo boards?

 

[terminator2k2]

Is there any chance you could just get a working motor from a different model 3 game and swap that over rather than changeing the complete dash ? Or is there more to it than that?

 

[Ordyne]

The encoder is the same on all m3, Naomi, chihiro etc dash motors.

 

[devtty0]

hmm.. is it my wiring to the drive board then? .. currently looks like this:

 

[Soundmaster]

Did you ever solve your Problem?

I just tried to put some new lindbergh drive boards in my ferrari Twin to Play outrun 2.

I got 2 different errors:




-drive board not connected

-drive board: (1) original point error

The steering Wheel is not turning during bootup, is this normal on Lindbergh cabs?

It was turning when i had installed the chihiro like on model 3 bootup.

Can someone show some pictures of how the boards are connected or a bootup Video.

 

[devtty0]

No - I never sorted it - after a lot of wiring and hassle I ended up giving up on the whole project in a huff and selling it all off at cost..

The guy that I sold the chinese drive board to said that it worked fine in his cabinet though
