VBL2350 Arduino serial

Hello,

i want to connect my arduino via serial to my vbl2350. The arduino should ask for the values etc Voltage,Amps.
I need a ttl rs232 converter?

please help me, i need this for my degree work.

thats enough?

or should i change something more than the baudrate to 115200?

The serial port uses 9600 baud rate. You should start there first. If it doesn't work, then try the 115200.

Edit: It needs to be set at the 115200.

Here is a link to the reference page if you don't already have it yourself. Since we are limited to the knowledge of the workings and code, I can only provide a small sample of coding that was provided to us.

arduino.cc/en/Reference/HomePage


Example code:

To read from a digital pin on the Roborun+ the code would be:
GetValue(_DIn,4)

Where as in Arduino the code would be:
digitalRead(4)

With both codes looking to Digital Pin 4,
An if statement would look like this on Roborun+:
If (GetValue(_Din,4) = 1)
<Then>
ElseIf (GetValue(_Din,4) = 0)
<Then>

And an If statement on Arduino would be:
If (digitalRead(4)=HIGH)
<Then>
Else If (digitalRead(4)=LOW)
<Then>

I hope this helps you.

thanks, but this is not the problem:

i must send over the rs232 something like "A?", and wait for the response.
I want to store this value´s on an SD card.


know somebody a projekt like this?

Try using the telemetry function.

Page 196 and top of page 197 of the user manual.

and how can i receive this string?

You will need to use your arduino to capture and parse the string to extract the values. If you do not know how to do this, you should ask on arduino forums. We are not arduino experts.

the parsing is not the Problem,

i mean is the telemetry string also send over the rs232?
