JTAG Programming Header
Figure 2–5 shows the schematic connections for the dedicated JTAG programming
header (J28). This header provides another method for configuring the FPGA (U33)
using an Altera USB-Blaster with the Quartus II Programmer running on a PC. The
MAX II JTAG configuration jumper (J26) allows the MAX II CPLD device to be
removed from the JTAG chain so that the FPGA is the only device on the JTAG chain.
Status and Setup Elements
The development board includes board-specific status LEDs, jumpers, and switches
for enabling and configuring various features on the board, as well as a
16 character × 2 line LCD for displaying board power and temperature
measurements. This section describes the status and setup elements.
Status LEDs
Table 2–5 lists the LED board references, names, and functional descriptions.

Board
Reference
LED Name Description
D3 POWER
Blue LED. Illuminates when board power switch (SW1) is on.
(Requires 14–20 V input to DC input jack J1)
D6 FAN
Amber LED. Illuminates to indicate an FPGA over-temperature condition. A fan sink
must be attached to the FPGA and running to prevent overheating.
D7 BLASTER Green LED. Blinks to indicate the embedded USB-Blaster activity.
D16 ERROR Red LED. Illuminates when a configuration error has occurred.
D17 FACTORY
Green LED. Illuminates when the factory POF image is successfully programmed into
the FPGA.
D18 USER
Green LED. Illuminates when the user POF image is successfully programmed into the
FPGA.
D19 TX Green LED. Blinks to indicate Ethernet transmit activity.
D20 RX Green LED. Blinks to indicate Ethernet receive activity.
