running a 5V relay via a BNC-2110?

[NeuralJ]

Thank, Dennis.

The NI DAQ card we are using is the 6025E.I know it has a analog output
of +/10 V, but I'm not sure of it digital ouput. What type of wires
would I need to get it connected to the Digital and Timing I/O blocks?

Using an expensive DAQ board to just provide 5VDC seems a little silly. You could buy a cheap wall transformer from radio shack for around $10. If you wanted, you could also build an extension cable from one of the internal power plugs inside your pc.
If you are not going to control the relay with digital lines from the daq board, you don't need DAQmx or the DAQ Assistant. Nor do you need either if you just provide 5 volts from the DAQ board. The DAQ board has a fixed 5 volt output pin. If you do want to experiment with controlling the DAQ board, then go to the NI Measurements>DAQmx palette. If it's not there, then DAQmx might not be installed. See if you have a Data Acquisition palette under NI Measurements. The functions there use an older DAQ driver.

Hi Neura,
Thanks for your reply. First, I have to say to you that I am pretty much new working with this kind of hardware and labview as well.
So, I just started trying to powering the circuit because I think, first step must be to understand signal level communication and after that, I can plan to start the programming.
The situation is: I have a infrared camera (phototach model 404B) wich is connected to block terminal(NI BNC-2110) through a coax cable. My pc has installed a PCI card 6024E and NI USB-6008. I already checked it through MAX(measurement & automation ) and it looks as is recognized.
I need to understand signal level communication of Camera or Sensor infrared because for starting the application I will get the data acquisition from this device. I dont see any light when I connected it to block terminal (BNC-2110).
I hope it ilustrate more to you my physical connection I have and I really appreciated your advices how I can build powering the circuit and If I need to do something with labview and so on. Thanks for your valuable help.
BR,
