Gx5641SetGroupOutputState

Sets the specified group output state.

Gx5642SetGroupOutputState (nHandle, nGroup, dwStates, pnStatus)

Name	Type	Description
nHandle	SHORT	Handle to a GX5641 board.
nGroup	SHORT	Group value is as follows: 0. GX5641_GROUP0 (channels 0 to 31) 1. GX5641_GROUP1 (channels 32 to 63)
dwStates	DWORD	Group’s output state. Each of the 32-bits represents a channel in the group. Bit 0 is the first channel in the group and bit 31 is the last channel in the group. Bit low - channel output is disabled. Bit high - channel output is enabled.
pnStatus	PSHORT	Returned status: 0 on success, negative number on failure.

For protection, by default all channel’s connections (TTL and Deferential) are disabled after power-up and reset.

DWORD dwMode;

// Sets all the channels in group 0 to conversion mode.

Gx5641SetGroupMode (nHandle, GX5641_GROUP0, 0, &nStatus);

// sets channels 1, 5, 8 TTL to differential conversion mode, rest of the channels are set to

// convert differential to TTL level.

Gx5641SetGroupConversionMode (nHandle, GX5641_GROUP0, 0x00000121, &nStatus);

// Enables all channels outputs.

Gx5641SetGroupOutputState (nHandle, GX5641_GROUP0, 0xFFFFFFFF, &nStatus);

// Returns all the channels in group 0 conversion mode
