2. Getting Started
2.1. System Configuration
2.1.1.
For testing the functions of the EVB B/D and developing applications, the EVB B/D should be configured as
shown below. First, the EVB B/D is connected to the PC using the crossed UTP Cable (for data
transmission) and the Serial Cable (for monitoring). Second, the dip switch and jumper should be set as
below;
① SPI Enable : J3
For interfacing W5100 with MCU through SPI mode, the pin of 2 and 3 of JP3 should go short. In case
that SPI mode is not used, the pin of 1 and 2 should be shorted.
