CC3200: CC3200

Part Number: CC3200

I need to replace about 50 to 100 feet of a 4 wire RS-485 Data bus cable with a wireless link, unlicensed band.  

Noticed the “Non-Isolated RS-485 to Wi-Fi Bridge” in TI Designs

Can a variation of the above be used ?   Are there other TI devices that  would accomplish what I need ?

I am advising  a group of biomedical engineering students on their senior project, it has the possibility of going into production.

Thought I found an off the shelf RS-485 wireless bridge but they are not working and the company is apparently out of business

    Hi Herman,

    The TI Design sounds like it would work for your purposes. You should decide if you will connect to an Access Point, or if you will have a Wi-Fi device at either end.

    Best regards,

    Thank you for your reply.   Perhaps I did not explain thoroughly.  I need to bridge about 50 feet of 4 wire RS-485  bus cable with a wireless link.   Just replacing a length of existing cable with wireless.  No access points involved, just cable end to cable end.    Bridge transparent to my data. My devices  need to see it just as it saw the section of cable it would be replacing

    Hi Herman,

    Wi-Fi can certainly cover that distance, and you can communicate with a device at either end via peer-to-peer, or one acting as an AP and the other as a station. This would be the terminal/interpreter mode in the TI design.

    There are other wireless technologies you can also consider, but you should think about the data rate you want and what your power source would be. This Wireless Connectivity Technology Selection Guide may be useful. The RS-485 transceiver in the TI design is connected via UART, which almost all of our wireless MCUs support.

    Best regards,

    Sarah
