CB34-EX
e t B u r n e r
Networking in 1 Day!
Key Points
• Instantly allows any RS-232
and/or RS-485 serial device to
communicate over a network
or the Internet ( custom
programming is required for
products which use CAN)
• Simple web page configuration
• Fully featured web server uses
standard Internet protocols like
TCP/IP, Telnet, and HTTP
• Use as a high-performance single
board computer or add Ethernet
connectivity to a new or existing
design
• Customize to suit any application
with a low-cost development kit.
CB34-EX
NetBurner’s Easy-to-Use High-Performance
CAN-to-Ethernet Device
Overview
The CB34-EX is a low cost, high-performance CAN-to-Ethernet device that network en-
ables both existing and new product designs with 10/100Base-T Ethernet.
Network Enable Existing Applications
The CB34-EX network enables serial devices right out of the box. No programming or
development is required; it is pre-programmed to convert RS-232 and RS-485 data to
Ethernet, enabling a serial device to communicate over a network or the Internet. The on
board web server provides easy device configuration via a standard web browser.
NOTE: Programming is required for products which use CAN.
Customize to Suit Any Application
The optional CB34-EX development kit enables you to create additional dynamic web
page content, filter serial and network data, or write completely new custom applications.
NetBurner has a solid reputation for developing platforms that facilitate rapid product
development, and the CB34-EX is no exception. The kit includes the hardware platform,
TCP/IP stack, uC/OS real-time operating system, Web Server, GNU C/C++ compiler and
linker, GDB graphical debugger, end-user device configuration and flash update utilities,
and much more. Please see the NNDK-CB34EX-KIT datasheet for more information.
Real 32-bit Performance
While other products in this price range are 8-bit processors with small amounts of paged
memory and limited performance, the Freescale ColdFire 5234 is a full 32-bit high-perfor-
mance processor. The CB34-EX has 8MB of SDRAM and 2MB of flash, providing plenty of
space for applications and buffering.

Connector Descriptions
The CB34EX has 3 serial interfaces: UART0 (RS-232), UART1 (RS-
485/422) and CAN. Each serial interface can be configured via
internal jumpers to appear on either the DB9 or Terminal Strip
connector.
