Advantech PCM-3780 manual Base Address Setting SW1

Base Address Setting (SW1)

Select an address which is not already in use by another card in the sys- tem. If you are installing more than one PCM-3780 card in your system, set the cards to different base addresses. The base address configuration switch SW1 controls each card's base address, as shown below.

Switch ON: Address Line Value = 0

Switch OFF: Address Line Value = 1

Table 3.2: Base Address Setting

Base Address	A6	A7	A8	A9
100H － 13FH	0	0	1	0
140H － 17FH	1	0	1	0
……
3C0H － 3FFH	1	1	1	1

For example:

Base Address 140H:

A6 OFF A7 ON A8 OFF A9 ON *Default Setting = 300H

The following example shows how to set the base address to 140H. The switch SW1 sum is set to 140H:

40H(A6=1) + 0(A7=0) + 100H(A8=1) + 0(A9=0) = 140

Address Line	A6	A7	A8	A9
HEX Value	40H	80H	100H	200H
