Refer to Chapter 3 for

additional system

examples.

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.
