Set Internal Switches to AutoCAD settings using the 9100 series User's Manual

    1.  The 9100 series tablet must have a firmware revision "F" or later to work with Wintab™ driver sets 2.x, 3.x, 4.x
         and 5.x.  Following are instructions to assist with verifying the firmware revision and setting the internal switches.

    2.  Following are a series of steps to disassemble the 9100 tablet.

                                ***IMPORTANT***
        a.  Disconnect all cables from the tablet and remove all covers from the port access holes before trying to remove
             the board train.  (The board train is the two attached circiut boards that are to be removed.)
                                ***IMPORTANT***

        b.  If the tablet is on a table, move it until the upper left corner of the frame overhangs the table edge.  If the tablet
             is on a pedestal, tilt it to vertical.

        c.  With a Phillips screwdriver, remove the cover from the upper left corner.  This cover is held by two screws
             recessed into the underside of the cover. The board train is suspended in a slot in the upper part of the frame.

        d.  Remove the lock screw next to the POWER button.

        e.  Depress the POWER switch, grasp the ribbon cable and partially pull the board train out of the slot.  Hold the
             power switch down until it slides behind the frame.

        f.  Place a thumb on each release tab of the ribbon cable connector. Using firm pressure, push the tabs outward
            unlocking the cable from the connector.   Remove the cable from the connector.

        g.  Using the cable connector as the grip, pull the board train straight out of its slot.

            ***Hold the ribbon away from the board train to prevent it from being damaged by the rough board surface.***

        h.  The first board in the train is the Digitizing Processor Board. "Switch Bank SB1" is on this board.

        i.  The second board is the Communication Interface board.  Switch Bank's. "SW1" and "SW2" are on this board.

    3.  Checking the firmware revison.

        a.  Locate the first board, the Digitizing Processor Board.

        b.  Check the first horizontal ROM chip closest to the Communication Interface Board connector for a sticker
             indicating the part number and revision.   This chip is located in the U3 ROM socket,

        c.  If the revision is not F, G, or H; ***STOP***.  This board can not be used with the Wintab™ driver sets 2.x, 3.x,
             4.x and 5.x.  Firmware upgrades are no longer available for these tablets.  Reassemble the
             tablet using the previous instructions in A.2 as a guide. ***Contact our Sales Department at 1-800-856-0732,
