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. ?

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. ?
