Zest_Interface_RS232
Overview
The Zest_Interface_RS232 is an electronics development board for 6TRON opensource platform.It offers 6TRON users a RS232 interface to devices, systems and sensors communicating with low power over a long distance.
The Zest_Interface_RS232 is built around the MAX3227IDBR ,a full-Duplex RS-232 transceiver with 1 Driver and 1 Receiver from Texas instrument. The tranceiver provides the electrical interface between an asynchronous communication controller and the serial-port connector.It operates at data-signaling rates of 1 Mbit/s in normal operating mode and a maximum of 30-V/µs driver output slew rate.
