Configuration

Base Address Selection(Switch1)

Switch 1 is used to select the base address of the card. The address selected is the address of the first UART. Each UART is offset by eight from the previous UART (e.g., if the board is set to 100H then the addresses would be as follows UART1=100H, UART2=108H, UART3=110H, UART4=118H, UART5=120H, UART6=128H, UART7=130H, UART8=138H.)

IRQ Selection(Switch 2)

Switch2 is used to select the IRQ that will be used by the board. Figure 2 shows the settings for the desired interrupts.

Figure 2

Interrupt Status Register(Switch 3)

The status register is the register used by some operating systems to determine which port on the card is generating an interrupt. The following figure specifies the DIP switch setting for the different addresses. The selected address should not conflict with the address block selected the Base Address.

300H	360H	3C0H
310H	370H	3D0H
320H	380H	3E0H
330H	390H	3F0H
340H	3A0H	OFF
350H	3B0H

Wait State Selection (Jumper JP1)

JP1 is used to select the number of wait states on I/O to the card.

Master/Slave Selection(Jumper JP3)

JP3 is used to specify if the card is in master or slave mode. If more than one card is placed in the same computer and only if you want all boards to use the same IRQ then one board must be jumpered as a master while all the others must be jumpered as slaves.  Note that you can place several cards jumpered as masters in the same machine if each board uses a different IRQ.  

If JP3 is jumpered(shorted), then the board is a master. If JP3 is not jumpered(open), then the board is a slave. When cards will be sharing IRQs, you must cascade the cards via jumper JP4.

Daisy Chain Jumper(Jumper JP4)

JP4 is used to daisy chain two or more cards together. The In of the master should be connected to the Out of the slave and so on.
