SETTING THE LOGICAL ADDRESS

The logical address of the SMIP II is set by two rotary switches located on the top edge of the interface card, near the backplane connectors. Each switch is labeled with positions 0 through F. The switch closer to the front panel of the module is the least significant bit (LSB or “Front”), and the switch located towards the back of the module is the most significant bit (MSB or “Back”). To set the Logical Address (LA), simply rotate the pointer to the desired value. For example, to set the LA to 25, first convert the decimal number to the hexadecimal value of 19. Next, set the back switch to 1, and the front switch to 9. See Figure 2-1.Two examples are provided below:

Example 1

LA	Divide
(decimal)	by 16		MSB	LSB
25	25 / 16	=	1	w/ 9 remaining	Divide the decimal value by 16 to get
					the MSB and the LSB.
		=	0001	1001	The 1 is the MSB, and the remainder of
					9 is the LSB.
		=	1	9	Convert to hexadecimal. Set the back
					switch to 1 and the front switch to 9.
