1. GX6384_GROUP_B
If the Switch Matrix is configured as one group with 64 columns the only Group is:
0. GX6384_GROUP_A
nRow
SHORT

1. GX6384_ROW_1: row number 1 (all models).
2. GX6384_ROW_2: row number 2 (models Gx6384-2 and Gx6384-3 only).
3. GX6384_ROW_3: row number 3 (models Gx6384-2 and Gx6384-3 only).
4. GX6384_ROW_4: row number 4 (Gx6384-3 only).
5. GX6384_ROW_5: row number 5 (Gx6384-3 only).
nColumn
SHORT
Specified column relay number is as follows:
0-31: Switch Matrix is configured as two groups with 32 columns (default configuration).
0-63: Switch Matrix is configured as single group with 64 columns.
pnState

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 one group with 64 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 in group A, row 0:

 

Gx6384SetGroupRow32Columns (nHandle, GX6384_GROUP_A, GX6384_ROW_0, 0x80113, &nStatus);
