Setting Up the Exciter’s Address
Your next step is to setup an address for each Exciter by using the S1 slide switch on the LFA21
board, as shown in Figure 5-2.
Figure 5-2: Setting Up the Exciter’s Address
The addresses must be sequential between 1 and 14. For example, if there are 4 Exciters, they must
be assigned addresses 1, 2, 3, and 4. Use the S1 switch to set the address to binary format. For
example, in binary format:
• address 1 is 0001
2
• address 2 is 0010
2
• address 3 is 0011
2
• address 4 is 0100

If the switch is in the ON position, the bit is set to “1”. Otherwise, the bit is set to “0”.The factory
default address setting is address 1 [0001

Note Figure 5.2 displays the S1 setting for address 1.
