3. Hardware Setup
The following instructions illustrate how to setup the hardware included with the kit.
1. Connect the AB4 Ethernet Development Board to the C8051F120 Target Board at J24 (Figure 2). Apply
slight pressure to ensure the mating 96-pin connectors are firmly connected.
2. Using the ribbon cable, connect the USB Debug Adapter to the C8051F120 Target Board at the JTAG
header as shown in Figure 3.
3. Connect one end of the provided USB cable to any available USB port on the PC (Figure 3).
4. Connect the other end of the USB cable into the USB connector on the USB Debug Adapter (Figure 3).
5. Connect the ac/dc Power Adapter to the C8051F120 Target Board at P1 (Figure 3). This connection should
power both boards. Power is indicated by the "PWR" LED on the C8051F120 TB.
Note: The 'F120TB places a 2
 resistor in series with the power supply net powering the AB4 Board. We recom-
mend replacing this resistor with a 0
 resistor to prevent large voltage drops, possibly triggering a V
DD
Monitor reset, when current demand increases.
