CP210x
USB
to
UART
Bridge
Controller
The
USB
interface
is
USB
2.0
compliant
(full
‐
speed,
12
Megabits
per
second).
The
CEL
MeshConnect
ISP
/
WNA
USB
dongle
is
powered
from
the
USB
port
and
requires
that
the
host
USB
port
be
capable
of
delivering
200
mA.
The
output
of
the
CP210x
Bridge
Controller
is
a
RS
‐
232
compatible
signal
which
will
be
used
to
interface
to
either
the
on
‐
dongle
MeshConnect
ZIC2410
IC
for
WNA
functionality
or
the
target
system’s
MeshConnect
ZIC2410
IC’s
UART1
peripheral
for
In
‐
System
Programming.
MeshConnect
ZIC2410
and
Antenna
When
the
MeshConnect
ISP
/
WNA
USB
dongle
is
operating
in
WNA
‐
mode,
the
MeshConnect
ZIC2410
in
conjunction
with
the
chip
antenna
is
responsible
for
looking
for
Simple
‐
MAC,
802.15.4
MAC
and
ZigBee
packets
being
transmitted.
The
received
packets
are
then
passed
to
the
CEL
Packet
‐
Analyzer
software
tool
via
the
CP210x
Bridge
Controller.
Status
LEDs
and
Switches
The
MeshConnect
ISP
/
WNA
USB
dongle
contains
3
status
LEDs
(Amber,
Red
and
White)
and
three
user
‐
accessible
switches
(two
push
‐
button
and
one
slider).
An
additional
slider
switch
becomes
available
