L4433A Example Program Segments

The following sections contain example program segments of commonly used instrument functions. .

The channel addressing scheme used in these examples follow the general form 1ccc where ccc is the three- digit channel number. The channel numbers for the L4433A are derived as follows:

Two-wire mode: the crosspoint digits. See the

For two- wire mode, the channel numbers are derived from or intersection of rows and columns, columns having two example below.

Displayed Channel	Means This...
1304	An L4433A (2-wire mode) where the crosspoint is
	row 3, column 4.

One-wire mode: For one- wire mode, the channel numbers are derived from a specific matrix number and the crosspoint or intersection of rows and columns on that matrix. See the example below.

Displayed Channel	Means This...
1437	An L4433A in 1-wire mode with matrix 4 and the
	crosspoint is row 3, column 7.

For information on specific configurations, refer to the simplified schematics for the L4433A later in this chapter.

For detailed example programs involving multiple drivers and development environments, refer to the L4400 Product Reference CD- ROM (p/n 34989- 13601).Setting 1- wire and 2- wire Modes

Example: Configuring the L4433A for 2-wire or 1-wire mode The following command configures the L4433A for 1- wire measurements. If you are using terminal blocks with the L4433A module, be sure to use the corresponding 2- wire or 1- wire terminal block.

N O TE	After changing the (1-wire / 2-wire) mode on the L4433A, you must
	cycle power on the L4433A for the new mode setting to take effect.
