xPC Target

Test 1, Ping Target System Standard Ping

If you are using a network connection, this is a standard system ping to your target computer. If this test fails, try troubleshooting with the following procedure:

1. Open a DOS shell, and type the IP address of the target computer

• ping xxx.xxx.xxx.xxx
  

1. DOS should display a message similar to the following.

   • Pinging xxx.xxx.xxx.xxx with 32 bytes of data:
     Replay form xxx.xxx.xxx.xxx: bytes-32 time<10 ms TTL=59 
     

2. Check the messages on your screen.

1. Ping command fails -- If the DOS shell displays the following message.

   • Pinging xxx.xxx.xxx.xxx with 32 byte of data:
     Request timed out.
     

   The ping command failed, and the problem may be with your network cables.

   To solve this problem, check your network cables. You may have a faulty network cable, or if you are using a coaxial cable, the terminators may be missing.

   Ping command fails, but cables are okay -- If the cables are okay, the problem may be that you entered an incorrect property in the Setup window.

   To solve this problem, in the MATLAB Command Window, type

   • xpcsetup
     

   Check that TcpIpTargetAddress, TcpIpSubNetMask, and TcpIpGateway have the correct values. On the host PC, open the xPC Target Setup dialog box, change the TCP/IP options, click the Update button, and then create a new boot floppy disk. On the target PC, reboot with the corrected boot floppy disk.

   For a PCI-bus:

   • Check that TcpIpTargetBusType is set to PCI instead of ISA.

   For an ISA-bus:

   • Check that TcpIpTargetBusType is set to ISA instead of PCI.
   • Check that TcpIpTargetISAMemPort is set to the correct I/O-port base address, and check that the address does not lead to a conflict with another hardware resource.
   • Check that TcpIpTarget IRQ is set to the correct IRQ line, and check that the line number does not lead to a conflict with another hardware resource.
   • If the target PC motherboard contains a PCI chipset, check if the IRQ line used by the ISA-bus Ethernet card is reserved within the BIOS setup.

   Ping succeeds, but test 1 with the command xpctest fails -- The problem may be that you have incorrect IP and gateway addresses entered in the Setup window.

   To solve this problem, in the MATLAB Command Window, type

   • xpcsetup
     

   Enter the correct addresses. Click the Update button. Recreate the target boot disk by inserting a floppy disk into the host disk drive, and then clicking the BootDisk button.
