Relay control with NI USB-6343

[ftaghaboni]

I am very new to these devices and trying to find my way around. I am trying to use a USB-6343 to control some relays on a test bench, I have looked at all the examples for creating a digital output and here is where I get stuck:

Configure the Task to use a burst export clock, which configures the
'       device for Burst Mode Handshaking, setsthe sample clock rate, exports
'       the clock on the specified PFILine, and sets the sample mode to
'       Continuous.

I can not figure out how to configure the task for burst export clock in NI-DAQmx tasks. what am I missing? I see the settings for sample clock type and clock source and active edge. am I suppose to configure them manually?

is there a simple example for triggering a digital output and producing a continuous signal as long as the trigger is on?

Regards,

Farid

The USB-6343 does not support Burst Mode Handshaking according to the documentation that I can find. Burst Mode is usually found only on our HS-DIO devices and the HS Switches. Now if you want to use Handshaking you can configure that in the triggering vi but if your priority is speed I would recommend against that. The USB devices have to use USB Bulk to emulate DMA(Direct Memory Access). It should be transferring at the fastest rate it can. What exactly are you trying to do? If you let me know I may be able to guide you further. As for configuring sample mode you can do that in the Sample Mode VI.

Alex,

Thanks for getting back to me. I am trying to control a bank of relays on a hydraulic test bench which activate different functions. I know how to use the analog outputs and analog inputs to control valves and record the data. I just need to figure out how to use the digital outputs to turn on / off the relays.

Alex,

that link is dead. I searched for "370784d.pdf" on the manuals site as well and it returned nothing.
