Comments

The Switch Matrix can be configured via software as two groups with 32 columns or one group with 64 columns. All
the Switch Matrix channels will be opened prior to applying the new configuration settings. Applying the same
configuration settings will not change the current group’s channels settings.

Use the

Gx6384GetChannel

function to retrieve the state of a specific relay.

NOTE:

The function returns an error if the Switch Matrix is configured as two groups with 32 columns.

Note:

In order to prevent power supply overloading the maximum number of all the relays that can be closed at

any given time cannot exceed 128. The function returns an error if trying to exceed the limit.

Example

The following example close relays 0, 1, 4, 8 and 19, 34, 36, 40-44, 63 in group A, row 0:

Gx6384SetGroupRow32Columns (nHandle, GX6384_ROW_0, 0x80001f14, 0x80113, &nStatus);
