The
ISA
auxiliary
module
provided
interfaces
for
RS232
serial,
line
‐
level
stereo
(analog)
audio,
and
IR
remote
‐
controls.
The
same
module
can
be
used
at
the
transmitter
or
receiver
end.
The
signal
directions
at
the
audio
and
IR
interfaces
are
switched
automatically.
The
signal
directions
at
the
RS232
interface
are
fixed,
but
can
be
easily
changed
to
suit
a
specific
application
with
an
external
null
‐
modem
cable/adapter.
Note:
The
IR
capability
is
designed
into
the
hardware,
but
not
currently
supported
by
the
firmware.
Check
with
Magenta
Research
for
applicable
