1. Safety instructions
•
The digital input box must be connected solely
to the "Digital Inputs" socket of a 3B NETlog
unit.
2. Equipment supplied
1 Digital input box
1 8-pin miniDIN connecting cable, length 600 mm
1 Instruction sheet for U11377
3. Description
The digital input box is used for distributing digital
input channels A, B, C and D of a 3B NETlog
(U11300) unit to four 8-pin miniDIN input sockets.
It allows for digital output signals from up to four
sensor boxes (e.g., photo gate U11365, laser
reflection sensor U8533380, and Geiger-Müller box
U11391) to be connected to the 3B NETlog
the same time.
It is also possible to perform logical operations
using digital inputs A and B via the 3B NETlab
(U11310) software

5. Operation
•
Place
the
digital
experiment. Example: an air track (e.g.,
U40400 or U40405).
•
Position two photo gates (e.g., U11365)
alongside the air track and connect them via
their miniDIN cables to the input sockets A and
B of the digital input box.
•
Connect the digital input box via miniDIN
cable to the 3B NETlog
•
Configure the two digital inputs A and B to be
linked using 3B NETlab
"Digital inputs A+B") and evaluate the results
from the experimental data.
