MAX3111E Evaluation Kit

The MAX3111E evaluation kit EV kit provides a proven design to evaluate the MAX3111E SPI /MICROWIRE compatible universal asynchronous receiver transmitter UART with RS-232 transceiver. The EV kit also includes software that provides a simple graphical user interface GUI for exercising the features of the MAX3111E. The MAX3111E uses the SPI/MICROWIRE interface for communication with the on-board MAXQ2000 microcontroller µC . The on-board DIP and momentary pushbutton switches are used to configure the MAX3111E internal registers. The EV kit can be connected to a PC serial port directly or through a straight-through extension cable. The PC is a data terminal equipment DTE device, and the EV kit is a data communications equipment DCE device. After the EV kit and the PC serial port are configured properly, the PC sends characters to the MAX3111E. The on-board µC reads the received data from the MAX3111E and displays the characters on the onboard 7-segment LED or sends back data to the PC. Other switches, jumpers, and pads are provided to modify the board to the numerous configurations available for the MAX3111E. Figure 1 shows a simple block diagram of the EV kit RS-232 only .
