SCN5 / SCN6 Hardware Thread

Is possible to connect two o more scn5 actuators to an only rs485<->usb converter?
The adaptor schemes show it should be able to manage up to 32 devices.
I think poeple are buying as many adapters as scn5 actuators have.
Which is the best setup?

Thanks, it make sense.

Thanks for the replies. I am not sure though how the push/push method makes any difference to the push/push method, as in both cases, they are still rigidly linked. There would never be 1-2mm of mechanical slop, and if there was, it would be due to wear, and would cause big issues with inaccuracy and rattling.

I thought about the linked system a bit more, and in principle I think it has some merit. The main reservation I have is when one of the actuators gets moving before the second one, it's effectively doing 100% of the pushing by itself, until the other one catches up... which means it has half the acceleration. Once they are both up and running, the second unit would still be receiving it's position say 10ms behind the other one, so they're never going to be in sync.

Perhaps I just need hardware sync or look for some bigger actuators...

There is no scenario in which you will double the capability of as SCN5 by adding a second SCN5 either yoked or opposing.

However, the reason why it often works is because in these forums you will typcially see far more than 1-2mm of slop in the typical DIY sim and also because the SCN5 has a different push force than pull force resulting in some improvement because at least one actuator is always at is strongest.

Your load requirement is not defined so no one can help you to determine if a stronger actuator is best.

Guten Abend!!! Ich brauche eure hilfe!
Wenn z.B. also mit zwei aktuatoren SCN5 den Devantech USB-RS485 adaptor benutzen werde, brauche ich zwei davon oder eine?
Auf dem bild ist nur eine zu sehen und wie sieht es aus mit dem USB A to Serial RS232 DB9 UART RS485 Adapter Converter.

was ist besser

Vielen Dank im Voraus !

Könnte man mit je zwei SCN6
eine zb 3dof Full Motion Plattform aufbauen?
Ist halt dann etwas träge mit bloss 100 Positionangaben per sec.
Aber wenn ich die gar nicht synchonisiert laufen lasse, sondern einfach
beide ans selbe RS485 Signal kabel?
Würden dann die 200 Positions/sec nicht bestehen bleiben?


Und reicht die Kraft,wenn man ca 60kg wiegt und das Display als Helm trägt.
Denn Sony bringt bald so ein 3D Display Helm raus,
damit wäre eine enorme Gewicht ersparnis für eine Full Motion Plattform drin.
Dazu kommt, dass man so die Umgebung nicht mehr wahrnimmt.
Das Gehirn kann dann die Bewegungen nur noch den wahrgenommenen Beschleunigungen zuordnen.
Das verlangt aber, dass die Software genau arbeitet,
denn stimmen die Bewegungen nicht mit dem wahrgenommen überein,
würde einem so Übel bis zum Erbrechen.

Hi,
i am trying to connect SCN5 with a USB-Rs485 converter.
my converter is something like
http://www.dealextreme.com/p/usb-to-rs-485-adapter-8504
http://www.diytrade.com/china/4/product ... normal_img

Same cable and connection only the brand different.
I see com11 in the list after connecting the converter. But can't see SCN5 with startHWrescan in forceprofiler.

USB-Rs485 Converter has 6 connection
1) T-/A 2) T+/B 3) R+ 4) R- 5)GND 6) +9V

i connected scn5
green cable to --> B (also tried other way)
White cable to --> A
Black -->gnd
Then i tried connecting T-/R+ and T+/R+ with cross cable and also tried adding 120ohm resistor. And with all the communication speeds nothing changed.

What should i do?

hi,
you must have a com under 10. in windows you must change the number to a number
between com1 and com9

Re: SCN5 actuator whirring, no movement?

Hello,

My SCN5 actuators were just connecting vias the Commander 2 sofware and one of them just started whirring, and the actuator rod is now free to move up and down with no tension while the actuators are plugged in. The rod has therefore become disconnected somehow? Can anyone help?

I look forward to any replies.

Cheers

AW: SCN5 / SCN6 Hardware Thread

Sounds like the drive pin between motor and linear drive is broken. It's a mechanical failure that can be fixed. Had it on both SCN5.

or you have a problem with the 24 volt without power on the scn5 you can move it up and down with your hands.

Re: AW: SCN5 / SCN6 Hardware Thread

hi!
i have the same problem like you since yesterday.
did you solve it? in that case, was it easy?
i might send the actuator back to the manufacturer (in my case, simxperience) in order to be reparied but i am afraid the shiping costs are gonna be too much...

Hi,
Just started building the PVC sim chasis. I am an electronics tech and would like to build a motion sim.
I understand the majority of the electronics but do not fully understand the motor/actuator firmware.
Are the firmware pages you are showing above part of a program you've purchased or some open source
firmware. Any help would be appreciated , I've seen some sims use motors as well.

Thanx, Jurgen

Hi,

Can you post a pix of how to connect the USB to 485 connection option to the motor ?
I am building my own adapter using your schematic, but not sure how to connect this to the motors. I saw the diagram above for the RS232-485 connection but nothing for the USB.

Thanx, Jurgen

ok i have read all the pages of the scn5/6 software and the 49 pages hardware and followed many dif setups and still cannot get the profiler to detect my scn6 . I might add that when o connect to my old pc winxp direct serial it does detect and center but on my vista or win7 i cannot detect can anyone help as i am sure it is just windows settings i am overlooking
note >>> I have tried the 120ohm resistor and grounding to the computer and th rts / dts settings have been trying for 4 days with information on this forum


I want to add that this is the USB to 232 i am using http://www.ebay.com/itm/150525882505?ss ... 1438.l2649

also here is the 232 to 485 i am using

>>>>>>>>>>>>>>>>>>>>>>>>MOVED TO SOFTWARE THREAD<<<<<<<<<<<<<<<<<<<<<<<<<<<<

I am sorry if i have this posted in wrong area , i am trying to detect scn-6 and this is where i have found the most information . here is some of the shots you asked for . i do not have a comport monitor i will go online and try to find one . I know it was back in 2008 that it say's you must copy the scn5 serial into the profiler plugin section ,is this still the case ? in the first pic you will see there is nothing detected . i have tried to get this to work to move on to more settings .

I cannot take pics of wiring at this time no cam, but here is the pin out and i have wired with the 120 ohm resitor and without also with the z diode and 2.2 k resistor . no ilk switch wired at this time just testing but will add when all test done just received the switches in mail about ten min ago .

I am looking for something like hyperterminal as windows vista does not have it . i downloaded 232 anylizer but not sure its what i need to run test on my converters .

I must say i am sorry if you dont believe i have read and read and studied the forums and manual . i may not be the smartist but i am trying to get what i can without bother to others .

Thanks for your devoted time .

Thank you i will move this to the software thread . realquik

I am having problems with my Hexin converter , Yesterday all was working fine and moving my scn6 actuator but today when using it the force profiler came up and said warning an interface was unplugged and then it would no longer detect the scn6's i checked all wires and looked good changed to a new converter and it worked just long enough to detect the actuators and again sent same message, warning an interface was unplugged, and would no longer detect any actuator. this has happened with 3 converters.
ANY HELP APPRECIATED !!!!
