    ISA 16/4 ADAPTER SWITCH DOCUMENTATION

    
       These instructions apply to Release 5.0 of the software.
    
    
    
       TokenExpress ISA Adapter Switch Settings
    
    
    
       The TokenExpress adapter comes equipped with two slide switches and one
    
       switch block.  These switches and switch block allow you to easily
    
       configure the adapter to fit your particular installation requirements.
    
    
    
       One slide switch is used to determine the speed setting for your
    
       adapter. This switch may be set at either 4 or 16 Mbps, depending on the
    
       speed of the Token-Ring to which your computer is connected.
    
    
    
       The second slide switch is used to select the cabling type that you will
    
       use with your adapter.  The STP setting enables output through the 9-pin
    
       connector (DB-9) for operation over Shielded Twisted Pair cabling.  The
    
       UTP setting enables the RJ-45 connector and the on-board media filter
    
       for operation over Unshielded Twisted Pair cabling.
    
    
    
       The switch block is used to determine the Remote Program Load (RPL)
    
       enable/disable, the RPL address, the interrupt level select, the I/O
    
       address select, and the DMA address select.  The possible switch
    
       settings are as follows:
    
    
    
       Switch 1 - RPL ENABLE
    
    
    
            On   EEPROM is disabled (Default)
    
            off  EEPROM is enabled
    
    
    
       Switch 2 - 6 - RPL Address
    
    
    
            2    3    4    5    6
    
            on   on   off  off  on   (Default - CC000-CDFFF)
    
            0    0    1    1    0    (0 = on, 1 = off)
    
    
    
            Switch 2 - 6 set the 8K address space for the RPL EEPROM.  The
    
            EEPROM can be placed on any 8K boundary from C0000 to FE000.  
    
    
    
       Switch 7,8 - Interrupt select
    
    
    
            7    8
    
            on   on   Interrupt 9 (Default)
    
            on   off  Interrupt 3
    
            off  on   Interrupt 10
    
            off  off  Interrupt 11
    
    
    
       Switch 9,10 - I/O Address select
    
    
    
            9    10
    
            off  off  A20-A23, A30-A3F
    
            on   off  A24-A27, A40-A4F
    
            off  on   A50-A53, A60-A6F
    
            on   on   A54-A57, A70-A7F
    
    
    
       Switch 11,12 - DMA select
    
    
    
            11   12
    
            on   on   DMA 5
    
            on   off  DMA 6
    
            off  on   DMA 7
    
            off  off  Programmed I/O
    
    
    
       NOTE:     Setting switches 11 and 12 to off forces the driver/adapter to
    
                 transfer data using programmed I/O.  Though not normally used,
    
                 this setting may be necessary if your computer does not
    
                 support the AT Bus Master Mode properly.
    
    
    
       When the TokenExpress ISA adapter is installed in an 8-bit slot of a
    
       PC/AT, programmed I/O is used regardless of the switch setting.
