Matrix Architecture
The 40-575A is a single pole switching matrix with 84 connections on the X-axis and 4 connections on the Y-axis.
Connections are made by operating the relays at the crosspoints between X and Y lines allowing single X-Y connections,
or X-X connections using a Y line as a path. The 40-576A, 40-577, 40-578 and 40-579 are controlled in the same way but
have matrix sizes of 64x6, 50x8, 36x12 and 28x16 respectively. The matrix architectures are shown in the diagrams below:

Section 4 - Programming
NOTE: The matrix supports concurrent switch paths for X to X and Y to X connections, however connections between
different Y axis lines (e.g. Y1 to Y2) are not permitted.
The entire matrix is treated as a single programming sub-unit designated as Sub-Unit 1. Some simple examples are show
on the next page using the provided drivers: the IVI driver, the Direct IO driver, and the IVI compliant driver.

Section 4 - Programming
Programming the Matrix Using The IVI Driver, Direct I/O Driver or VISA Driver
This section provides some code fragments which show how to control the High Density Matrix using the IVI Driver, Direct
I/O Driver or the VISA Driver.
Once the drivers are installed the manual “Sys40Prg.pdf” and driver help files which fully describes these functions can
be found in the Pickering folder(s) or the Pickering entries on your Start Menu.
The card must be opened before use and closed after using the following function calls:
Direct Driver - Open with PIL_OpenCards or PIL_OpenSpeciedCard and close with PIL_CloseCards or
PIL_CloseSpeciedCards respectively.
VISA Driver - Open with pipx40_init, and close with, pipx40_close.
Setting a Matrix Crosspoint:
Using the IVI driver:
pi40iv_Connect(vi, “x1”, “y2”); //set crosspoint x1, y2 to on
pi40iv_Disconnect(vi, “x1”, “y2”); //set crosspoint x1, y2 to o
Using the Pickering Direct I/O driver:
DWORD SubUnit = 1;
PIL_ClearSub(CardNo, SubUnit); //clear all crosspoints to o state
PIL_OpCrosspoint(CardNo, SubUnit, 2, 1, 1); //set crosspoint x1, y2 to on
PIL_OpCrosspoint(CardNo, SubUnit, 2, 1, 0); //set crosspoint x1, y2 to o
Using the VISA driver:
ViUInt32 SubUnit = 1;
pipx40_clearSub(vi, SubUnit); //clear all crosspoints o state
pipx40_setCrosspointState (vi, SubUnit, 2, 1, VI_ON); //set crosspoint x1, y2 on
pipx40_setCrosspointState (vi, SubUnit, 2, 1, VI_OFF); //set crosspoint x1, y2 o
