2 1BIntroduction

Microsemi’s PD-IM-7648 evaluation system consists of: PD-IM-7500 MB Motherboard (see Figure 2),

PD-DB-7648 Daughterboard (see Figure 3), power supply, case, and cables. The evaluation system (Figure 1)

provides designers with the needed environment to evaluate the performance and implementation of PD69208-

PoE Manager and PD69200-PoE Controller mounted on the PD-DB-7648 Daughterboard.

3.1 12BSwitches and Jumpers

The evaluation system comprises switches and jumpers used to select the desired configuration states of the

board. Default configurations are indicated as 'default.'

3.1.1 17BUART Communication Selection

There are three UART communication options:

USB to UART (connecting USB cable to U7).

For this connection a driver for CP210x should be installed. The driver can be downloaded

from http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx.

RS232 to UART (connecting RS232 cable to J33).

UART input (connecting UART cable to J26).

J6 on DB must be open in order to work in UART mode.

Using J11 and J12 jumpers, the following three options are available (see Table 2).
