Setting the Local Address
Set via S1, Switches 6, 7, & 8
Up to eight DBK210 boards can be used in a single Daq system. However, each board contains four
module banks and each bank must have a unique address. This is accomplished with three micro-switches
(6, 7, and 8) on switch S1 and a fixed set of two digits for each bank.
To illustrate, addresses are seen as follows where XXX represents a binary format; e.g., 000; 001, etc as
determined by micro-switches 6, 7, and 8, since each can independently be set to “0”or to “1.”
Bank A, Channels 0 through 7: XXX 00
Bank B, Channels 8 through 15: XXX01
Bank C, Channels 16 through 23: XXX10
Bank D, Channels 24 through 32: XXX11
Assuming we were using three DBK210 boards, for a total of 96 channels, we could use the following
address scheme:
1
st
DBK210 board, micro-switch 6 set to 0, 7 set to 0, and 8 set to 0, resulting in 000.
2
nd
DBK210 board, micro-switch 6 set to 0, 7 set to 0, and 8 set to 1, resulting in 001.
3
rd
DBK210 Board, micro-switch 6 set to 0, 7 set to 1, and 8 set to 0, resulting in 010.
In this example the three boards would have addressing as follows:
DBK210, 1
st
Board
DBK210, 2
nd
Board
DBK210, 3

Example of Local Addresses for Three DBK210s in a Common Daq System
The Local Address must be unique for each board in the Daq system. In addition, the
board’s address must match the address setting in DaqView. The DaqView aspect is
explained in the Software Setup section, which begins on page 7.
