Using Serial to turn Projector on

Projects Networking, Protocols, and Devices

Hello Wassup

I have an Acer Z650 Projector which i want to turn on using a serial comland can I do this by connecting an RS232Max TTl‘s rx and tx to the arduinos rx and tx?

Pinout
VCC - 5v
Rx- arduinos RX
Tx- arduinos tx
GND - GND

Thanks in advance

  • Always show us a good schematic of your proposed circuit. Give links to components.

Post the interface description.

The Acer Z650 Manuals are available here.

There isn't much information about the interface other than to say that it is RS232.

Here are some of the commands:

I think that you need to connect the RS232 to UART converter's Tx to Arduino Rx, and the converter's Rx to Arduino Tx.

I also have to agree.

Unit Rx to Arduino Tx
Unit Tx to Arduino Rx

Actually using some of the samples above you can likely use Tera Term or any similar terminal emulation software. That should tell you if you have communication.

Sorry you all for not writing too much let me fix that

Sadly I don’t have any images or schematics. This is just an Idea floating in my head.

Do i have a flight simulator with two Acer Z650 Projectors and instead of using the remote that came with the Projectors i want to turn it on using a button with my Arduino uno r3. I read about the Serial commands and that you can turn on this projector with this HEX String
2A 20 30 20 49 52 20 30 30 31 0D
Settings
Baud Rate (Default) 9600
Data Bits 8
Parity None
Stop Bit 1
So looked into the ardunio and the internet and found two pins on the Arduino RX and TX. But after looking into the internet, i saw that you need an RS232 to TTL Adapter. I went with this one

https://www.amazon.de/progress-tracker/package/ref=pt_redirect_from_gp?_encoding=UTF8&from=gp&itemId=mlkorulpqinsuo&orderId=305-4426114-0788350&packageIndex=0&shipmentId=85955743766302

I want to connect the RX of the Adapter to the RX of my Arduino
And the TX of the Adapter to my Arduinos TX
And GND to GND
But the Datasheet from my projector says the following
RxD receives data from the external computer
TxD transmits data to the external computer
GND ground for data signal
I dont get what they mean for ground.

So my questions are:
What do I have to connect where
And is my pinout connect RX(arduino) -> RX(Projector) and TX(arduino) -> TX(Projector)
GND -> GND
And can somebody please code this i dont know how to code

Thanks to everyone that is replying and helping

You were told by myself and another member that Rx to Tx and Tx to Rx and I also suggested :

There is no Tx to Tx or Rx to Rx. What part of this do you not understand?

This is not a free code forum, there is a paid help section.
