2.3 Configuring the Hardware
- Before you install the MC1 board, you need to consider the following configuration options:
2.3.1 Arranging Multiple Boards in a PC
- In each PC, your boards will be connected to one another with the MVIP bus cable. Your boards should be positioned according to these guidelines:
2.3.2 Configuring the MC1 Board's MVIP Bus Termination
- Your MC1 board comes from the factory with MVIP bus termination disabled. To enable or disable termination:
- Locate jumper pin blocks JP2 and JP7 on the face of the board (shown in Figure 3).
- Install or remove the jumpers, as follows:
Figure 3. Location of Important Components on the MC1 Board
2.3.3 Configuring the MC1 Board's I/O Address Space
- The MC1 board occupies 16 contiguous I/O addresses. These addresses must be unique and must not conflict with any other devices in your system.
- The default factory setting for the base address is 0x0640. If you need to select another base address, set DIP switch S1 (shown in Figure 3) as directed in the following table:
-
- The most common type of address conflict is with devices that only control the lower 10 address bits (0 through 0x3FF) of the AT bus. In this case, an address conflict at 0x0140 does not go away when the board is set to address 0x2140, but does get resolved when the board is set to address 0x0160.
- Make a note of the base I/O address that you set the board to use. The software installation program you use may prompt you for this address later.
2.3.4 Connecting the MC1 Board to the MC1 Bus
- MC1 boards are connected together with SCSI-3 type connectors in a daisy chain fashion. The two ends of the MC1 bus must be terminated. In order to meet FCC emissions requirements, the cables must be shielded.
