The record program can be used with all types of data acquisition cards which support the National Instruments DAQ-mx driver. Therefore, some hardware specific parameters are needed. Select Extras -> Options via menu bar to view and change these settings. The following entries are necessary for the recording: Digital Trigger Channel is the channel selection for the digital trigger signal. Insert the input where the digital trigger signal is connected Digital Trigger Resolution defines the resolution of the digital trigger signal. If you have e.g. 16 digital triggers defined above the complete analog voltage range (+-10V), the correct setting is 2^4. Digital trigger value 0 is the analog voltage between -10V and -8.75V, digital trigger 1 is the analog voltage between -8.75 and -7.5V. If only one digital trigger is generated, you can use a TTL signal, the switching level between trigger 0 and trigger 1 is 1.5V. So you can define any TTL signal as digital trigger channel and use it to trigger between 0 and 1 without an additional hardware. Nr of channels of the first A/D Converter defines the channels of the first data acquisition card (e.g. device 1), higher numbers will automatically be routed to the second A/D converter (e.g. device 2). Converter Input Range defines the expected voltage range of the analog input signals. Default is +/- 10V. Threshold Stimulus Current [mA] defines the threshold for the current measurement used for the H-reflex plot. It defines the minimum current which is necessary to detect current peaks within the current signal. Please note that the current measurement is only possible with an additional current measurement hardware. Paths to the Instrument setup files and the default file for IMAGO Record. You find the path entries in a separate tab. First select the correct instrument setting. More information
