Description

The TIDA-00485 TI Design uses Texas Instruments SimpleLink Wi-Fi CC3200 Internet-on-a-chip Wireless MCU module to create a data bridge between an RS-485 network and a Wi-Fi network. An SN65HVD72 transceiver provides the RS-485 Interface with 12 kV of ESD protection, and additional protection is provided on board. The design can be powered with AC or DC power up to 30 V RMS or 48 V peak.

A version of this design with an isolated RS-485 interface is presented in TIDA-00486.

Features
  • Add Wi-Fi® connectivity to an RS-485 network quickly and simply
  • CC3200 Application Processor Provides Adaptability to Customer Communication Protocol
  • Wide Input Voltage Range of 18V to 30V AC, 12V to 48V DC
