No data is sent to USB converters.

Hi there.

Today I tried to connect two SCN5's, (the third is on its way) to SimTools.
I followed the directions stated on the quick start, uploaded the plugin for Assetto Corsa, then assigned the axis, assigned the interfaces, COM8 and COM3. Both SCN5's have ID :0. I ran the game, saw movement on the Virtual Axis. I connected and powered the SCN5'5 and with game turned of, tried to test them. No movement at all. The green lights on the converters never blinked. (They blink when the converters are connected to the powered hub). I was concerned about the converters and ran a loopback test using Hyper Terminal. Text is sent from the keyboard was displayed and the green lights in the converter blink with each keystroke.
I checked the support forum for the game manager and game engine, without a result that could help me, I am including screen shots of the configuration, and will continue to look for solutions, but any hint or workaraund would be greatly appreciated

Thank you very much for the prompt reply and for the suggestion

I changed to 10.000. No change in behavior.I did test using the Axis testing tool, no movement of the SCN5's and the green lights indicating data transfer never blinked. They do when I test the converters using Hyper Terminal. Game engine is using data from the game, as the Virtual Axis screen indicate changes in all forces and angles.
Before I tried the Axis Testing tool I ran the game in tuning center and saved the captured MaxMin. Tomorrow I will uninstall and re-install SimTools, and follow the quick install guide carefully, and see if I overlooked any detail, specially in the Game Manager.
I am including here the schematic for the control box. It shows only one of the SCN5's. I believe there a\are no errors, but would appreciate any comments in the accuracy.

Hello yobuddy,
No, they do not move at all.

I have only tried it with SimTools. I looked for XSim 2.0, that I have seen recommended for testing, but it seems to have vanished.

If the actuator doesn't move on the start or with the manual tool in simtools they are not going anywhere. So you have a not working pair of SCN5 and as yobuddy told you, it can be for several reasons. Lets start from zero (even if it seems that you aren't a noob), which kind of converters are you using? Did they came with drivers? Is the installation of the driver gone right? (Even if they respond with the tool you are using, it doesn't mean that they are set for working with simtools)

hello, i was also thinking about the drivers. did you install those drivers ?

what about the wiring .... try to use the wiring tutorial to connect the converters instead of the one you said have no diods ...

use devantech usb-rs485 . It works for sure and the drivers work also

i used to have same issues (way back before) because the divers where not good enough for windows 7x64 few years ago. so use hardware that we know for sure that works.
good luck

Hi nclabs,

The converters i am using are shown in the link below.

The driver installed, 2.12.0.0 was selected by Windows.
The driver details are listed on the screenshot.
I checked power on the power connector of the scn5 and I see 24V between pins 1 and 2 and 19V between pins 2 and 8 .
.
The schematic of the control box is shown in one of the posts above, in PDF form.
Thank you guys for all the suggestions and tips. I should receive a scn5 this week and will try again. If it works , I might have a problem with the scn5's. If not I will order the Devantechs.

I had this type of thing, try the latest ftdi driver for your usb converter but i also noticed is there a 5v used for scn5 as thats what i have and was wondering if these usb interface work or not as i have to change mine.
Thats why i ask about the 5v if its needed

I asked this earlyer if you can run 3 wire not the 4 wire with 5v im really intrested if this will get working on 3 wire without the 5v as these are alot cheaper usb converters for me to buy as i need two as my vscom comi will not work with the simtools.
If you get this working i will order some tomoz

I'm using the Digitus RS485 converter (that have 4 wires) but I'm using only 3 of them, so I think you can!

Brilliant !!!
Thanks for that at least i can get some now with abit of confidence.

Hi yobuddy,

I tried with serial printer checked, and no response, even after i downloaded and installed the latest FTDI driver (2.12.6.0 ) for the chip in the converter. . I will order three Devantech USB to 485RS today. Simtools seems to configured right. The Virtual axis tool shows two interfaces in action, sway moves left and right when in turns, and surge moves a under breaking, acceleration and gear shifts. I measured the voltage between TRx+ and TRx- on the USB converter and it show 0.6V Voltage between ground and TRx+ is 1.3V, and between TRx- and ground is 1.23V. I don't know what I should expect in terms of voltage for the converter. Anyway, to eliminate the possibility that these converters do not work with SimTools, I am ordering the Devantech converters.
I have a schematic here. It is a downloadable file. I have traced this schematic a zillion times, and seems to be right. If you can have a peek at it, and see if is correct I would appreciate it greatly.

Thanks again for your help, it is appreciated very much.

I would give these guys on here abit more time to see if they can solve the issue with youand help before you start spending, i did notice a 5v jumper on the usb converter and are the jumpers set right for whats needed ... ect just trying to push all avenues ;-)
Im prob not the best to give advice atm but i would keep trying as things like this can be a very silly tiny little things.
Im sure these guys on here love a good challenge tho

I have ordered three Devantech USB to 485RS converters. After they arrive, together with the third SCN5, I will unninstal an re-instal SimTools, follow the Quick start guide and see what happens. It would be great if any of the experienced members here would have a look at the schematics I posted above and see if I didn't do anything wrong.
I cannot detect anything out of the ordinary The photos show the control box. In the photo on the right, a partially wired box is shown. Black wires in the terminal strip are connected to GND (-) of the power supply and the anode of the 27V Zener and to and from the terminal strip to terminal 2 of the SCN5. The red wires in the terminal strip are connected to +24V in the power supply and to the 2.2 kOhm resistor, and through the terminal strip to terminal 1 of the SCN5. The tree short blue wires are connected to the junction of the resistor and the cathode of the Zener diode and to the bottom terminals of the contactor (which is triggered by the kill switch) The top terminals of the contactor are connected to terminal strip and to terminal 8 in the SCN5.
