Software explanation Press the round Green Connect button to create a link between the PC and the control board. There are 2 main interface boxes: 1. Motors (top) -...

uno. 8. If you are operating more than one motor, run through the same procedure and configure motors for other addresses on the board. Calibrate the pump using the media you are intending to use the pump for. Use precision scales with tare function. Initiate new chain by pressing the New Chain (Ctrl+N) on the project box. Drag and drop the motor into the chain box. Uno International Ltd. Stepper Control Board Manual

5. Depends the side where you reservoir is choose either move forward or move backward. 6. Put the pump dispense side into a receiving vessel 7.

Press the stop button as soon as you see that the tubes are primes throughout their entire length and void of any air bubbles. 8. Enter 2000 steps which represents 10 full motor revolutions Uno International Ltd. Stepper Control Board Manual

uno. 9. Set rate - a speed which is typical in your application. As any common stepper motor has 200 steps per revolution, 1000 steps/second means 5 full revolutions per second or 300rpm (1000/200*60). 10. Choose the motor from the chain list and press the Green "Run" button. This will rotate the motor 10 full revolution (=2000 steps). 11. Carry out 10 dispenses and calculate the mean value. 12. Go back to Motor Configuration of the motor you are calibrating and choose "Pump" as description of the motor. 13. Enter the mean value you calculated as µl/revolution. 3. Changing the configuration...

3. Specify the type of motor whether Pump, Linear Drive or Rotary Drive. The parameters associated with your chosen motor type will be updated automatically such as µl/revolution if you chose Pump. 4. Enter the value you established during the calibration process whether µl/revolution, mm/step or steps/revolution and press OK. 5. From now on, whenever you wish to run the pump, you can enter the volume you would like to dispense, the speed of dispense and the direction - whether forward or backward (dispense or aspirate). 6. Save your settings. Uno International Ltd. Stepper Control Board...

4. Working with chains 1. You can run a single motor at any number of intervals, at any interval duration as many time as you wish. 2. Right Click in the Chain box and choose "Add Repeat", "Add Delay" or "Add Backstep". Each time you add one of these functions it will be added to the Chain box. 3. Drag the function you requested to the position you want and specify each function separately. You can delete any of the functions by right-click and choosing Delete. You can specify: Repeat: Number of repeats Delay: Period of delay between actions in seconds Backstep: Volume of Backstep, it's...

uno. 5. Adding repeat function to a particular set of commands If you wish to repeat specific set commands do the following:    Right click in the chain pane and choose "Add Repeat" Specify the number of repeats drag the commands you wish to repeat onto the "Repeat" command Example You have written the following commands: You would like to repeat 5 times the addition of die to the cell. Right click and choose "Add Repeat". Drag the "Add die to cell" line and the backstep onto the "Add Repeat" Uno International Ltd. Stepper Control Board Manual

Now drag the sub menu into a position in the protocol where you want these actions to take place. Uno International Ltd. Stepper Control Board Manual

uno. 6. Scheduling You can choose to run any chain at any intervals - as long as the computer is on, the Boxer Pump Controller program is running and the pump is powered up.
