Figure 2 shows an example of a typical application for
to work with low voltage logic (connected to V
seperate supply voltage V
with the IRED Anode connected to the unregulated
battery V
the regulated power supply and saves therefore
costs. Alternatively all supplies can also be tied to
only one voltage source. R1 and C1 are not used in
this case and are depending on the circuit design in
most cases not necessary.
I/O and Software
In the description, already different I/Os are
mentioned. Different combinations are tested and the
function verified with the special drivers available
from the I/O suppliers. In special cases refer to the
I/O manual, the Vishay application notes, or contact
directly Vishay Sales, Marketing or Application.
For operating at RS232 ports the ENDEC TOIM4232
is recommended.
