Jumper Setting
2-4 Blackfin USB-LAN EZ-Extender Manual
When using an ADSP-BF533 or ADSP-BF561 EZ-KIT Lite, the user 
must not place any jumpers on 
JP1. Placing a jumper on JP1 can damage 
the extender card and/or the EZ-KIT Lite. The user must power the 
ADSP-BF533/ADSP-BF561 EZ-KIT Lite and USB-LAN EZ-Extender 
with the 7.5V power supply provided with the EZ-KIT Lite.
When using an ADSP-BF537 EZ-KIT Lite without the 
Power-over-Ethernet feature, the user must not place any jumpers on JP1. 
The user must power both the EZ-KIT Lite and extender with the 7.5V 
power supply provided with the EZ-KIT Lite.
When using an ADSP-BF537 EZ-KIT Lite with the Power-over-Ethernet, 
the user must place a jumper between JP1 pin 2 and JP1 pin 3. The user 
must power both the EZ-KIT Lite and USB-LAN EZ-Extender with the 
CAT5E Ethernet cable, which provides power over the signal pairs. The 
Ethernet cable must be plugged into the Ethernet connector of the 
ADSP-BF537 EZ-KIT Lite, but not the USB-LAN EZ-Extender. The 
7.5V power supply provided with the EZ-KIT Lite should not be used.
For an overview of the Power-over-Ethernet interface, refer to 
“Power-Over-Ethernet” on page 1-5.
