RS485 to wireless converter set up

Hardware
1

Instructions are very vague. I am looking to use the RS485 to wireless converter in place of conventional wires between communicating legacy products from our catalogue. Can you please assist?

You can use these right out of the box. the default RS485 baudrate is 9600.
connect one on the transmitter side and one on receiver side.

As far hardware connection goes–
You will need to connect A, B and 5-24VDC power supply.

The unit you have is the new version of the device, we are working on updating the document.

let me know if you have any questions.

Thank you for your response.

I can see that the modules are communicating, but unfortunately the packets that are being received are not the same as the packages that are being sent.

I cannot find a direct datasheet for this module, however I have came across a couple of resources that seem to suggest that I need to implement software in order to use the device as a wireless replacement to data cable. Is this the case?

My RS485 2 wire system sends frequent ‘handshake’ requests to ensure constant updates and communication is monitored.
I bought this with the purpose of offering it as a response to expensive cable-laying ground-works.

Is there something I am doing wrong here?

Is there an easy work-around I can try?

Thank you for your time,

Kind regards,

The common reason for data mismatch is baurate issue.
Also do you know whats the length of the RS485 packets ?

can you confirm your rs485 baudrate is 9600 ?

5

Yes, I can confirm we use 9600 baud rate.

I know that the data packet length can vary depending on the message type.

the max payload supported by device is 100 byte. in most cases this is sufficient.

The USB modem we have is for configuration.

can you share all other other RS485 settings of your device. like stop bit, parity bit etc

I can send a datasheet of some product protocols which should cover this information, but I will need to send it to an email address.

you can respond to the ticket you opened earlier and attach it there.
