External Analog (Ext. Ana.)
Figure 2.5:
External analog pulse sequence behavior
The External Analog mode is similar to the External TTL, except that the driving current is proportional to the voltage ap-
plied on the BNC input connector (Fig.
, top). On the input BNC, a maximum voltage signal corresponds to a maximum
driver current. Should the current set on the light source be less than the maximum current, any voltage corresponding
to a higher current will clip the output waveform (Fig.
, bottom). To avoid any clipping of the output waveform, the
maximum current setting must be equal to or greater than the corresponding maximum analog input voltage.
2.4 Connected to Doric Neuroscience Studio Software
1. Connect the LED Driver to the power outlet with the included 12 V power adapter and turn the LED Driver switch
ON.
Always power the LED Driver before connecting the USB cable to the computer for a proper driver in-
stallation.
2. Install the Doric Neuroscience Studio Software on the computer. Double-click on the setup DoricStudioX.X.exe
file located on Doric USB memory stick supplied with the LED driver and follow the on-screen instructions.
3. Connect the
USB-A/USB-B cable
to the driver and the computer.
4. Connect each
M8 connector
of the
Combined LED
to the LED driver using an M8 electric cable.
5. With the system connected, the software can be used to control the device in
External TTL, External Analog,
Internal TTL and Internal Complex
modes. See section
for more details on using the software.
