This topic is ONLY for GripAlyzeR.
The operation of the gripper device or another external interface device is through a Data Aquisition Device (e.g., DAQPad 6020E from National Instruments).
o Interaction of GripAlyzeR program with the device requires the appropriate driver for the data acquisition module. The following device is normally used with the gripper device from Neuroscript.
- Data Acquisition Pad NI-DAQPad-6020E for USB, <100 kS/s, 12-Bit, 16 Analog Input Multifunction DAQ. Download Driver for this module from the NI website here.
o Run the NI Measurement & Automation explorer that is installed with the driver.
o Go to MySystem > Devices & Interfaces
o Verify that the DAQpad 6020E is listed and if not, try rerunning the NI Measurement & Automation, or press Refresh (F5). Also make sure that it shows the DAQPad as Device1. If not, right click on the device listed > Properties > Set Device number = 1
o Connect the DAQpad Interface provided with the device and the upper and lower gripper to the connector pins on the interface.
o Use a 12 V, - to + AC/DC power supply for both the NI DAQpad and the interface circuit.
o Switch on the NIDAQ pad. The Device configured green LED at the back of the device should now be on.
Testing the channels using Measurement & Automation explorer
o Run the NI Measurement & Automation explorer
o Right click on the MySystem > Devices & Interfaces > DAQPad6020E > Test Panel.
o Choose Channel = 0 and lightly tap/apply pressure to the upper grip sensor plate. The test panel window will show the corresponding variations. The output from all the channels at rest is 5 V. For Channel 0, the range of voltage variations is 5-10 V.
o Similarly, Channel = 1 corresponding to load sensor and Channel = 2 for lower grip can also be tested. For Channel 1, the voltage range is 5 V - 0 V (Negative direction) as it is pushed in to make contact between upper and lower grip. For channel 2, range is 5 - 10 V.
