1. About the EthernetBlaster
Communications Cable
Introduction
The EthernetBlaster communications cable connects to a standard Ethernet network
port with an RJ-45 connector. This cable communicates with client systems using the
TCP/IP protocol and supports both static and dynamic IP addressing. The
EthernetBlaster communications cable can be plugged into an existing 10/100 Base-T
Ethernet network to communicate with clients remotely or interfaced directly via a
standard 10/100 Base-T Ethernet port using a crossover cable. Because design
changes are downloaded directly to the device, prototyping is easy and you can
accomplish multiple design iterations in quick succession. Harnessing the power of
an Ethernet network, multiple users can remotely access Altera® devices, bringing a
new level of productivity to prototyping and debugging.

target circuit board, and 12.0 VDC (0.875A) input power for the EthernetBlaster
VCCSUPPLY (a 12.0 VDC wall transformer is supplied).
1–2 Chapter 1: About the EthernetBlaster Communications Cable
Introduction
EthernetBlaster Communications Cable User Guide © June 2008 Altera Corporation
The EthernetBlaster VCC(TARGET) pin must be connected to the appropriate voltage for
the device being programmed. The pull-up resistors on the target circuit board for the

Chapter 1: About the EthernetBlaster Communications Cable 1–3
Introduction
© June 2008 Altera Corporation EthernetBlaster Communications Cable User Guide
The status LED on the target port side of the cable displays the operation status of the
EthernetBlaster communications cable. See Table 1–1 for a description of each LED
status modes.
Static & Dynamic IP Addressing
The EthernetBlaster communications cable supports both static IP and dynamic IP
addressing, the latter by means of Dynamic Host Configuration Protocol (DHCP). By
default, the EthernetBlaster cable is configured at the factory to use dynamic IP
addressing. Upon power up, the cable attempts to obtain an IP address from your
network DHCP server. The Status LED is green and blinking while the network
address is being obtained and the cable is initializing. This process may take up to two
minutes.
When an IP address is obtained and the cable is ready to use, the status LED emits a
steady green light. If the attempt to obtain an IP address is unsuccessful (the DHCP
server may be down or absent), the cable switches to static IP addressing. The default
IP address is configured to 192.168.0.50. If static IP addressing is used, you must
configure your computer to an IP address in the same subnet as the cable to
communicate with it. The default setting requires your address to be in the 192.168.0.X
network domain.

Introduction
This chapter describes how to administer your EthernetBlaster communications cable:
■Managing Passwords
■Changing the Administrative Password
■Changing the Quartus II Remote Connection Password
■Resetting the Hardware
■Firmware Upgrade
Managing Passwords
Networking allows multiple users in both remote and local locations to use the
EthernetBlaster communications cable, increasing the productivity in prototyping and
debugging. However, because of this flexibility, it is necessary to limit and control
user access using the provided password service in the EthernetBlaster
communications cable setup.
The EthernetBlaster communications cable contains two types of passwords, an
administrative password and a Quartus II remote connection password.
The administrative password is the master password used to enter the EthernetBlaster
administrative web page. If you know the administrative password you have full
control of settings and the ability to modify both the administrative password and the
Quartus II remote connection password.
The Quartus II remote connection password enables clients to add the EthernetBlaster
hardware to their Quartus II Programmer hardware setup. This password is used to
control who has access to the EthernetBlaster communications cable. However, they
do not have access to the EthernetBlaster administrative web page and cannot modify
the settings or change passwords.
1When you change the Quartus II remote connection password, client systems using
the EthernetBlaster communications cable must remove the hardware from their
Quartus II Programmer hardware setup. See “Removing the EthernetBlaster
Hardware from the Quartus II Software” on page 1–13 for details. The hardware then
needs to be added back into the Quartus II software. See “Setting Up the
EthernetBlaster Hardware in the Quartus II Software” on page 1–12 for details.
