world
Wireless LAN OEM Serial Port Adapter

Product Brief OWS451 (UART interface)
The OEM WIRELESS LAN SERIAL PORT
ADAPTER™ 451 series from connectBlue is a
module with UART interface and fully embed-
ded TCP/IP stack and driver. It is developed
for reliable, high demanding industrial devices
and applications providing state of the art
low power features and dual-band support
for both 2.4GHz and 5GHz radio bands. The
module is presented as a serial port/UART to
the host. Raw serial data is sent to the mod-
ule, which will package the data into TCP/
UDP packages and transmit via Wireless LAN.
The module minimizes the work needed to
implement Wireless LAN (IEEE 802.11a/b/g/n)
in a device as it provides all hardware, type
approval, EMC certification etc.
