Example of a WaveBook Daisy-Chain with three WBK17 Modules
Unit* Channel #
WaveBook 0 (dig I/O)
WaveBook 1-8
1 st WBK 9-16
2 nd WBK 17-24
3 rd WBK 25-32
4 th WBK 33-40
5 th WBK 41-48
6 th WBK 49-56
7 th WBK 57-64
8 th WBK 65-72
How Channel Numbers are Determined
The analog input channel numbers are determined by the order of connection among the
WaveBook and attached WBK modules.
• Channel 0 is the WaveBook’s 8-bit digital I/O port.
• Channels 1 through 8 are the WaveBook’s main channels.
• Channels 9 through 16 are located on the first expansion unit connected directly
to the WaveBook.
• Additional channel numbers are added consecutively (in groups of 8)
with each added WBK module (see table at right).
* WBK in the “Unit” column refers to a module such as a WBK10A, WBK14, WBK15, WBK16, WBK17, WBK18.
Note that as this document goes to print the channel numbering method has not been determined for the WBK40 and
WBK41 modules.
