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 Interface Select : JP19, JP20, JP21, JP22
JP19 ~ JP22 are used for selecting the interface of W3150A
shown in Fig2.2, JP19 ~ JP22 are selected as A11 ~ A14 to be used as BUS interface. For the use of
SPI mode, the pin of 2 and 3 should be shorted. In this case, JP19 ~ JP22 will be selected as MISO,
