I have an Invacare Orion with a Rhino2 control unit DS90
3: I measure directly at the rs232 connector pin 3 and minus I see a signal every time the port swapped...
4: is it important which usb. rs232 cable i use? actually I should have the right cable because I measure at pin 3 and minus a clean signal which changes as soon as the port is changed by the software.

This method of serial communication is sometimes referred to as TTL serial (transistor-transistor logic). Serial communication at a TTL level will always remain between the limits of 0V and Vcc, which is often 5V or 3.3V. A logic high ('1') is represented by Vcc, while a logic low ('0') is 0V.
RS-232 (Recommended Standard 232) telecommunications standard. By the RS-232 standard a logic high ('1') is represented by a negative voltage – anywhere from -3 to -25V – while a logic low ('0') transmits a positive voltage that can be anywhere from +3 to +25V. On most PCs these signals swing from -13 to +13V.
The board in the pic IS NOT RS232 it is TTL.gcebiker wrote:Wouldn't that RS232 cable just replace your Red RS232 to USB board you are using woody ?

The top speed for the Eloped is quoted as "Top speed 15 km / h " ......So ...it is , most likely already at 100%.Ive noticed that the engine stop pulling after it has reached the speed 14 km/h. Its just a 400w engine so perhaps it at 100.
You will need to do a lot of soldering.But i dont get if i can just use an rs232 or if i need to do alot of soldering.
YesIs dr90-a01 a rhino2 controller.
YesWas there an modified software as well?

As Daf I need to setup a dr90-a01 controler.
I already got the software, the OEM dongle, the DWIZ adapter + XL3/Molex 4pins adapter and the USB/RS 232 adapter.
So if I'am right I just miss the RS232 to Hirose plug cable
In order to built it can you confirm this and by the way confirm that :
RS 232 pin 2 goes to pin 2 of Hirose plug
RS 232 pin 3 goes to pin 3 of Hirose plug
RS 232 pin 5 goes to pin 4 of Hirose plug
Thank you

thank you very much for your help...
