Comments

The function sets the specified channel to convert differential signal to TTL level or convert TTL level to differential.

For protection, by default all channels are disabled after power-up and reset. The channels can be enabled and or disabled by calling Gx5641SetChannelOutputState.

Note: The channel should be set to conversion mode prior calling this function by calling Gx5641SetChannelMode otherwise the function will return an error.

Example

The following example sets channel 0 to conversion mode, sets the conversion to be TTL level to differential, enables the channel and returns the channels conversion mode:

 

SHORT nMode;

Gx5641SetChannelMode (nHandle, 0, GX5641_CHANNEL_MODE_CONVERSION, &nStatus);

Gx5641SetChannelConversionMode (nHandle, 0, GX5641_CHANNEL_CONVERT_TTL_TO_DIFFERENTIAL, &nStatus);

Gx5641SetChannelOutputState(nHandle, 0, GX5641_CHANNEL_OUTPUT_ENABLE, &nStatus);

Gx5641GetChannelConversionMode (nHandle, 0, &nMode, &nStatus);
