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 
(decimal) 
Divide 
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. 
  
Convert to hexadecimal. Set the back 
switch to 1 and the front switch to 9.
