2.2 System Requirements

To install and use your TX 3220 board, your system must have:

2.3 Configuring the Hardware
Caution:

The TX 3220 board is shipped in a protective anti-static container. Leave the board in its container until you are ready to install it. Handle the board carefully and only hold it by its edges. We recommend that you wear an anti-static wrist strap connected to a good earth ground whenever you handle the board. Take care not to touch the gold fingers which plug into the PCI bus connectors.

2.3.1 Terminating the H.100 Bus

In your system, your H.100 boards are connected to one another with an H.100 bus cable. Any board located at the end of the H.100 bus must have bus termination enabled, as illustrated in Figure 3. The bus termination is controlled by a DIP switch as explained in Section 2.3.2.

Figure 3. H.100 Bus Configuration



If your system contains MVIP-90 boards, one of your TX 3220 boards will be connected to the H.100 bus and the MVIP-90 bus via the MVIP Bus Adapter. The end boards of the H.100 bus must be terminated. The end boards of the MVIP-90 bus must not be terminated, if you are using Natural MicroSystems' ISA boards.






2.3.2	 Configuring the DIP Switches





The TX 3220 DIP switch is located on the front of the board, below the H.100 bus.



DIP switch S1 (shown in Figure 4) controls the H.100 bus termination. By default, all S1 switches are set to OFF (H.100 bus termination disabled). Setting the S1 switches to ON enables H.100 bus termination. You should only set all S1 switches to ON for the boards that are on the ends of the H.100 bus.


Note:  All the switches in the DIP switch S1 should be set to either ON or OFF.

2.4	 Installing the Hardware





Once you have set the DIP switch on the board, you are ready to install the TX 3220 board in your system.






2.4.1	 Installing the Board in Your System





To install the TX 3220 board:


    


  1. If necessary, configure the board as previously described.
    

    

  2. Switch off the computer and disconnect the power cord from the back of your system unit.
    

    

  3. Remove the cover from the computer chassis.
    

    

  4. Find an open PCI bus slot and remove the blank slot cover from the chassis.
    

    

  5. Arrange your TX 3220 board and other H.100 boards in adjacent PCI bus slots.
    

    
Insert the TX 3220 board firmly into the slot. Make sure the gold-striped edge of the board is seated properly in the expansion slot groove and the bracket of the board is in the groove which previously held the slot cover.
    

  6. Making sure the top of the board's bracket is aligned with the hole on the top of the expansion slot, replace the screw which previously held the blank slot cover.
    

    

  7. If your system contains MVIP-90 boards:
    

      

    

  8. Arrange your MVIP-90 boards in adjacent ISA bus slots. Make sure each board's ISA bus connector is seated securely in a slot.
    

    

  9. Connect your MVIP-90 boards to the MVIP-90 bus cable.
    

    

  10. Connect the MVIP Bus Adapter to the TX 3220 and the MVIP-90 bus cable as described in Section 2.4.2.
    




  • Connect the TX 3220 board to the H.100 bus cable.
    

    

  • If you have multiple H.100 boards, connect the H.100 bus cable to each of the H.100 boards.
    

    

  • Replace the cover, and connect the computer to its AC power source.
    

    

    • 

    

    2.4.2	 Connecting to the MVIP-90 Bus
    

    


    The MVIP Bus Adapter connects the H.100 bus to the MVIP-90 bus. This allows boards connected to the H.100 bus to access the MVIP-90 bus, and allows MVIP-90 boards to access the first 16 streams of the H.100 bus. When connecting to the MVIP Bus Adapter, the first 16 streams of the H.100 bus must be configured to run in MVIP-90 mode (clocked at 2 MHz). 
    


    The MVIP Bus Adapter (Figure 5) contains a connector to an H.100 board (such as the TX 3220) and the MVIP-90 bus.
    




    Figure 5.	 MVIP Bus Adapter
    

    

    If your system contains TX 3220 and MVIP-90 boards, you must use the MVIP Bus Adapter. The MVIP Bus Adapter connects the MVIP-90 bus to the H.100 bus as shown in Figure 6. Only one MVIP Bus Adapter is required in a system. The board with the MVIP Bus Adapter should always be closest to the ISA card.
    




    Figure 6.	 Connecting to the MVIP-90 Bus
    

    

    To connect the MVIP Bus Adapter, refer to Figure 7 and follow this procedure:
    

      


    1. Connect the right angle connector (JP1) on the MVIP Bus Adapter to the connector (J11) on the TX 3220 board.
      

      

    2. Support the MVIP Bus Adapter by connecting the threaded mounting piece to the MVIP Bus Adapter and the TX 3220 board using two #4 screws.
      

      

    3. If you have multiple H.100 boards, connect the H.100 bus cable to the
      TX 3220 board and to each of the other H.100 boards.
      

      

    4. Connect the MVIP-90 bus cable to the connector on the MVIP Bus Adapter.
