B. Card Addressing

The card address is set by installing appropriate jumper pairs

on JP2, pins 1 thru 16, as shown in Fig. 3.

Addresses A15 thru A10 (JP2-1 thru 11) are jumper selectable

for defining the base address of the card from 0000H to FC00H

on integral 10H boundaries, where H denotes a hexadecimal

number.

IMPORTANT: For addresses A15 thru A10 (JP2-1 thru 11), an

installed jumper for a given address bit sets the bit to 1 (true)

and an uninstalled jumper sets the bit equal to 0 (false).

Examples for setting the base address are as follow:

Example 1. Set a base address of 0000H.

No jumpers are installed for JP2-1 thru 11.

Example 2. Set a base address of 3800H.

Intall jumpers JP2-5, JP2-7 and JP2-9.

Jumpers JP2-13 and JP2-15 are used to select the serial port

address for the UART. The card addresses for these selections

are given in Table I. It should be noted that for a base address

of zero, the addresses of the UARTs are the standard serial port

addresses COM1 thru COM4 of the IBM PC.

IMPORTANT: For addresses A4 and A8 (JP2-13 and JP2-15) ,

uninstalled jumper for a given address bit sets the bit to 1

(true) and an installed jumper sets the bit equal to 0 (false).
