3.      Installation:

        The following illustration shows the mounting bracket of
        your ISDN adapter board (8 bit):
                       _____
                       \    |
                        |   |
                        |___|
                        |___|<- ISDN line connector
                        |   |
                        |   |
                        |   |
                        | o |<- ISDN connection status display (yellow LED)
                        | o |<- ISDN interface status display (green LED)
                        |   |
                        |___|

        |        |_____| <- DIP switches
        |                          |
        |                         _|
        |                        |_ <- ISDN line connector
        |                          |
        |                          |

        |                     __   |
        |____________________|  |__|


        Use the DIP switches S1..S4 on the board to select the I/O address
        and IRQ line of the ISDN  of the ISDN adapter board:


         -------------------------------- ----- -----
        | I/O adresse                    | S1  | S2  |
        |--------------------------------|-----|-----|
        |   160h ( default setting )     | off | off |
        |   170h                         | off | on  |
        |   260h                         | on  | off |
        |   360h                         | on  | on  |
         -------------------------------- ----- -----

         -------------------------------- ----- -----
        | IRQ                            | S3  | S4  |
        |--------------------------------|-----|-----|
        |   2 ( default setting )        | off | off |
        |   3                            | off | on  |
        |   5                            | on  | off |
        |   7                            | on  | on  |

        Install the dlls under WIN3.xx:

        a.) Choose the COM port using the DIP switches.

            If you want a different setting, please read your manual or
            have a look on your board.

        b.) Install the MicroLink ISDN board in your PC
            considering the usual safety rules (look manual).

        c.) Install the DLL's with the setup tool from the windows
            directory.

4.      Notes:

        V.120 under CAPI 1.1 and CFOS (version newer than 07/15/96):

        Enter the following AT-command:

            AT B12 S17=1 S76=1

        Now, the ISDN adapter board tries to get a V.120 connection
        erverytime you dial "ATDn" (n = number)..

        If you want to get back to X.75 mode, you have to enter:

            AT&F

               - - - - - - - - - - - - - - - - - - - - - - - -

        V.120 under CAPI 2.0 and CFOS (version newer than 07/15/96):

        Enter the following AT-command:

            AT B12 S17=1 S76=1

        Now, the ISDN adapter board tries to get a V.120 connection
        erverytime you dial "ATDn" (n = number)..

        If you want to get back to X.75 mode, you have to enter:
