Arduino RS232 Serial communication to adapter

[lass5216]

Hello Community.

I seek your help with my ultrasonic distance measure project.

I have an Arduino nano every with a Maxbotix distance sensor.

I would like to output the range data through serial communication to an adapter cube (ARRI LCUBE CUB-1).

How should I approach this? I have attached a manual from the adapter cube. Watch page 23. Am I able to just take the TX from the Arduino and input it to the cube in "pin 4 RxD 232". Should I also connect ground and voltage? The serial guide from Arduino states the following:
"Serial communication on pins TX/RX uses TTL logic levels (5v). don't connect these pins directly to an RS232 serial port: they operate at +/- 12V and can damage your Arduino board." How should I act with this information?

All the best, Lasse.

You need one of something like this

Google "rs232 to TTL"

for other choices. Usually these can operate with just 5 volts, the +/- 12 volts needed is generated from that supply. But check to be sure.

Obviously these come with standard connections or solder points, you will need to scare up whatever physical arrangements your device affords for connections.

Edit: yeah, I don't recognize that 8 pin connector 7 radial and 1 center pin.

You may follow the setup given below using Software UART Port and the TTL <--->RS232 converter module.
