... RS-232/422/485 applications. NOTE: Although the module is capable of supporting the typical serial communications required by RS-232, RS-422, and RS-485 networks not compatible with the electrical interfaces for these types of networks. The module has CMOS inputs and outputs and would require an appropriate converter for the particular type of network it is connected to. Wi.232EUR User’ ...

... Figure 3: Wi.232EUR Networking Concept The module is designed to interface directly to a host UART. Three signals are used to transfer data between the module and the host UART: TXD, RXD, and CTS. TXD is the data output from the module RXD is the data input to the module. CTS is an output that indicates the status of the module’ ...

... UART for processing. The modules only implement the ISO reference network stack up to the MAC layer, so they are transparent to link layer addressing schemes. Therefore, the modules can work with any link-layer and higher protocols in existing today ...

... However, modules that are not configured in the same way will not be able to communicate reliably, causing poor performance or outright failure of the wireless link. All modules in a network must have the same mode configuration to ensure interoperability. Every Wi.232 module has read-only internal registers that contain factory programmed information that includes calibration data and a 48-bit MAC address that can be used by the host application for higher level, connection oriented protocols ...
