Remote Control through a PASCO Interface
1.
Switch the voltage input to “external” by moving the ON/OFF switch to OFF (EXT.). The cart can now receive power from the
external source and the battery is shut off.
2.
Connect the Variable Speed Motorized Cart to the PASCO Interface.
•
If you are using a PASCO 750
ScienceWorkshop
Interface and Power Amplifier, use the included cable to connect the External
Input Port (EXT. INPUT) on the cart to the power output ports on the Power Amplifier.
•
If you are using a PASCO 850
Universal Interface
, use the included cable to connect the External Input Port on the cart to the
power output ports of the 850 Interface.
3.
Start the PASCO data acquisition software (such as DataStudio or Capstone) and choose and adjust the signal that you want the
interface to output. (See the software instructions for more information.)
4.
In the software, click ON in the signal control window to start outputting the signal.
5.
Click OFF in the signal control window to stop outputting the signal.
ON/OFF by Time Pulse Accessory (ME-9496)
1.
Mount the PASCO Time Pulse Accessory on the Variable Speed
Motorized Cart by inserting the studs on the bottom of the Time Pulse
Accessory into the holes in the accessory tray of the cart.
NOTE
: Be sure that the ON/OFF switch is in the
OFF
position before
doing the next step.
2.
Plug the 3.5 mm phone plug of the Time Pulse Accessory cable into
the External Input Port on the Variable Speed Motorized Cart.
3.
Test the Time Pulse Accessory.
•
Turn the TIME control switch on the Time Pulse Accessory to
“0” (0 = 1 SEC).
•
Flip the ON/OFF switch on the Variable Speed Motorized Cart to
ON
.
•
Gently press the START push button on the Time Pulse Accessory.
After a two second delay
, the Motorized Cart should turn on automatically and run for one second before turning off automatically.
Test the other time intervals on the TIME control switch in the same manner.
CAUTION: Never supply the Variable Speed Motorized Cart with external source
voltages greater than ± 6 volts.
