Low Cost Serial-to-Ethernet Bridge for Embedded Applications
Description
The Xecom XE232NET Serial-to-Ethernet Bridge
modules provide a simple solution for connecting
micro-controller based embedded systems to a Local
Area Network. These modules include all of the
hardware and software needed to link the serial port
on the micro-controller to the local area network.
The XE232NET Serial-to-Ethernet bridge operates
much the same as any Xecom serial modem. AT
commands are used for control and configuration of
The XE232NET. The XE232NET also utilizes the
same pin configuration as the Xecom XE5690SM
modem family. This permits one design to support
either Ethernet or dial-up modem connectivity with a
simple module swap.
Xecom offers two versions of the XE232NET. The
XE232NET-1 with the Ethernet isolation transformer
and the XE232NET-2 without the isolation
transformer. An Evaluation Kit is available, model
number XE232NET-K
Features
Miniature Dual-In-line Package: 2.1” x 1.0”
• TTL compatible serial interface;
• Operates from a single +3.3 volt power supply
• Includes 10 Base-T Ethernet MAC and PHY
• Embedded protocols include, Ethernet, TCP, IP, UDP,
ICMP, DHCP, ARP, HTTP, POP3, and SMTP
• Command and control with Serial AT Commands
• IEEE 10BASE-T compatible
Models
XE232NET-1: Serial-to-Ethernet Bridge module with
Ethernet isolation transformer included
• XE232NET-2: Serial-to-Ethernet Bridge module
without isolation transformer.
• XE232NET-K: Ethernet Evaluation Kit includes
XE232NET-1; evaluation board, required cables, and
power supply
XE232NET-1ITR: XE232NET-1 with an operating
range of -40C to +85C
• XE232NET-2ITR: XE232NET-2 with an operating
range of -40C to +85C

XE232NET AT Commands
The XE232NET uses "AT" commands for
configuration and control. This section describes the
AT command format and lists the commands,
registers and result codes.
Omitted Parameters - Most commands include a
parameter which determines how the functions will
be set. When the command parameter is omitted
from the command string, it is assumed to be a 0.
Command Mode: XE232NET enters command
mode on power-up, reset, a lost connection, or
receipt of the escape code. In command mode the
modem accepts commands from the host on
transmit data. Appropriate result codes are returned
on received data.
Command Line Format
AT commands follow a strict format. Each
command line, except A/, begins with the prefix
AT. The "A" and "T" may be both upper case or
both lower case but cannot be of different cases.
Multiple commands may be combined into a single
command line of up to 48 characters. Commands
are executed in the sequence they appear upon
receipt of a carriage return. Spaces inserted into the
command line are not placed in the buffer.
The command line can be edited with a backspace
before it is executed. The backspace erases the
previous character in the command line. Register S5
allows the user to select a character other than
backspace to edit the command line.
If the command buffer overflows, the modem issues
an "ERROR" result code, and the command line is
not executed. Register S3 allows the user to select
a character other than a carriage return to terminate
the command line.
Escape Characters - A 3 character escape
sequence may be entered to switch the modem into
command mode while on line. The escape
character, set by Register S2, must be entered 3
times in succession to execute the escape. An AT
command must then be entered within the period
defined by S12 to enter command mode. The
default escape sequence is "~~~"
Result Codes - The Ethernet Bridge issues a result
code after each action. Result codes may be sent as
full words, one or two digit numeric codes, or may
be disabled all together. Each result code ends with
a carriage return when numeric result codes are
chosen. When full word result codes are chosen, a
Line Feed and Carriage Return precede and follow
each result code.
Email Modes: The XE232NET can transfer
information as an Email from either of two Email
modes, transmit and receive. Once Email uploading
or downloading is complete the escape sequence,
default "~~~", terminates Email mode.
Transmit Email mode is accessed with the AT+ET:n
command. Where “n” represents the destination
Email address. Upon receipt of this command the
XE232NET logs into the Email Server and any data
placed on TXD will be transferred to the destination
address as Email.
Re-Execute Last Command - The A/ command
causes the modem to re-execute the last command
line. This is the only command which does not
require the "AT" prefix.
The AT+ER command causes the XE232NET to log
into the Email server and look for incoming Emails.
Data from these received emails wil be presented
on the RXD output.
