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(R) devices, bringing a new level of productivity to prototyping and debugging. Supported Devices You can use the EthernetBlaster communications cable to download configuration data to the following Altera devices: Stratix(R) series FPGAs Cyclone(R) series FPGAs MAX(R) series CPLDs APEXTM series FPGAs ACEX(R) 1K FPGAs MercuryTM FPGAs FLEX(R) series FPGAs ExcaliburTM FPGAs You can perform in-system programming of the following devices: Advanced configuration devices, including EPC2, EPC4, EPC8, and EPC16 devices. Serial configuration devices, including EPCS1, EPCS4, EPCS16, EPCS64 and EPCS128 devices. In addition, the EthernetBlaster communications cable supports target systems using 5.0-V TTL, 3.3-V LVTTL/LVCMOS, and single-ended I/O standards from 3.3 V down to 1.5 V. Power Requirements The EthernetBlaster communications cable requires between 1.5 V and 5.0 V from the target circuit board, and 12.0 VDC (0.875A) input power for the EthernetBlaster VCCSUPPLY (a 12.0 VDC wall transformer is supplied). (c) June 2008 Altera Corporation EthernetBlaster Communications Cable User Guide 1-2 Chapter 1: About the EthernetBlaster Communications Cable Introduction 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 configuration/programming signals must be connected to the same power supply as the EthernetBlaster VCC(TARGET). Software Requirements The EthernetBlaster communications cable is available on the Windows, UNIX, and Linux platforms, including the following: Windows NT 4.0 Windows 2000 Windows XP x32 edition and x64 edition Windows Vista x32 edition and x64 edition Solaris 2.6 Solaris 2.7/7 Solaris 8/9 Solaris 10 Red Hat Linux version 7.3 Red Hat Linux version 8.0 Red Hat Linux version 9 Red Hat Enterprise Linux WS 3.0 Red Hat Enterprise Linux 4 Red Hat Enterprise Linux 5 HP-UX version 11.0 or later Use the Quartus(R) II software beginning with version 4.0 to configure your device.

See Table 1-1 for a description of each LED status modes. Table 1-1. Status LED Modes Status LED Status Description Red-Green Power on, reset Green, blinking Cable initialization Green, steady Cable ready Blue, blinking Downloading data to target printed circuit board 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. (c) June 2008 Altera Corporation EthernetBlaster Communications Cable User Guide 1-4 Chapter 1: About the EthernetBlaster Communications Cable Cable Setup 1 Refer to your operating system manual or contact your network administrator to verify that your network supports DHCP services and for instruction on how to change your IP address.

EthernetBlaster Communications Cable Administration 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. 1 When 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. Changing the Administrative Password To change the administrative password, follow the directions below: 1. Open and log into the EthernetBlaster administrative web page in your browser. 1 See "Cable Setup" on page 1-4 for instructions on accessing the administrative web page using your specific connection.
