Catapult EJ-1 and Catapult EJ-2 Quick Start Guide
 
 
This document will take you through the basic steps to install and configure your Catapult EJ-x device.
  1. Make sure that you have the entire kit
    The Catapult EJ-x kit that you received should have the following items:
    1. Wall adapter with a DC barrel jack
    2. Catapult EJ-x unit
    3. Cable (either flying leads, or ribbon cable, depending on what was ordered

  2. Get the configuration software
    Download the Catapult EJ-x configuration utility from here
    This is a Windows™ 32-bit or 64-bit installable EXE - install it in the location of your choice.

  3. Contact your system administrator
    Ask your System Administrator for a standard Ethernet cable that supports Fast Ethernet (100 Mbps).
    You may need to discuss the setup for the unit with your system administrator.
    To begin with, here are the factory-default settings for Catapult EJ-x:
    Setting Value
    DHCP Enabled
    IP Address 192.168.15.120
    Network Mask 255.255.255.0
    Gateway 192.168.15.1

    If you have a DHCP server, Catapult EJ-x will attempt to acquire an address from this server.
    Furthermore, it will request a hostname (via the DHCP protocol) of btejXXXX where "XXXX" is the last
    four characters of the Ethernet MAC address (this address can be found on a label along the
    side edge of your device). For example, if your device's Ethernet MAC address is 02:06:32:00:f3:a2,
    then the DHCP requested hostname will be btejf3a2.

    NOTE: With the factory default settings, Catapult EJ-x will attempt to acquire its IP settings
    (IP address, Network Mask and Gateway) from the DHCP server. If this negotiation is unsuccessful
    (or if it times out), then the device will default to the factory IP settings (as indicated in the table above).
    If you do not have a DHCP server, then you will need a cross-over Ethernet cable to attach the
    Catapult EJ-x directory to your PC, to configure it. This may require you to change the IP address and
    network mask of your machine - talk to your System Administrator about this.

  4. Connect your Catapult EJ-x
    Now that you have your Ethernet cable, connect the Catapult using this cable to an Ethernet switch,
    and connect power to the device with the provided wall adapter.

    CAUTION: Use of a wall adapter other than the one provided may permanently damage your Catapult unit.

    NOTE: It is advisable that you do not connect the JTAG target cable to the device at this time.

    After powering up your device, you should notice the green LED at the top of the Catapult EJ-x unit light up,
    indicating that the device is ready. You should also see the green LED on the RJ45 Ethernet connector
    lit - which indicates that the Ethernet link with the switch has been established.

    You should now be able to "ping" the device (your system administrator can tell you what IP address was
    assigned to the device, or if a name server is configured on your network (in which case you might be simply
    be able to ping using the DHCP requested name of the device.


    TIP: If you see both green lights lit on the unit (the READY LED and the Ethernet Link LED on the RJ-45 connector),
    but are unable to ping the device, this might mean that the DHCP negotiation failed, or that you are not on the same
    subnet as the device. Talk to your System Administrator to determine what might be the problem.

  5. Configure your network settings
    Make a note of the IP address provided to you by your System Administrator. Now, launch Catapult Configuration utility. When the utility
    opens, click on the "Connect Target" button. When prompted, enter the complete IP address of the device you are
    trying to configure, without any extra whitespace or other characters. Then, select the "IP configuration" button,
    and make changes to the settings, as instructed by your System Administrator. You will need to power-cycle the
    device for the new settings to take effect.

    CAUTION: Take great care when entering the values here. Incorrect settings may render the device inaccessible!
    In particular, take care when using the Static IP settings.


    TIP: A persistent IP address for the device is desirable. If possible, use a static IP address. Alternatively, configure
    the DHCP server to assign a fixed IP address to the device's MAC address. Or configure the DHCP server to lease
    the IP address to the device for a very long time.

  6. Connect to your target board
    Power-off your Catapult EJ-1 unit. Plug in the JTAG target cable to the Catapult EJ-1 device, and attach the JTAG
    cable (flying leads or ribbon cable) to the target board.

    CAUTION: Incorrect attachment of the flying leads or ribbon cable to the target board may permanently damage the
    target board, the Catapult EJ-1 device or both. Take great care when attaching the cable to the board, and always
    cross-check the connections to ensure a correct, clean contact.

    Power on the Catapult EJ-1 - it is now ready to use! Consult the application guide on how to attach your application
    to the Catapult device on the network.
