Figure 4 shows an example of a typical application for to
work with a separate supply voltage V
transceiver with the IRED anode connected to the
unregulated battery V
of 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 ENDECS TOIM4232 or
TOIM5232 is recommended.
Note
TFBS4711 echoes the TXD signal at the RXD output during
transmission. For communication this signal is to be correctly
ignored by the controller or the software. The echo signal is
implemented for test purposes in mass production.
