XE5692H
June 2006
Half-Size, Low-Cost Global Embedded Modem
Description
The Xecom XE5692H is a complete, global modem
in a compact, surface-mount module. It covers less
than half the board space of the leading competitor
and is less than half as thick as well.
Xecom includes user transferable FCC Part 68
registration with every modem module. This allows
the system designer to add a modem to a process
control, remote monitoring, point-of-sale, or remote
diagnostic system without Part 68 certification.
Only Xecom offers embedded modems in leadless,
surface-mount form. As a result, the XE5692H is
not only substantially smaller than the competition
but the surface-mount package frees additional
space on the bottom of the application board for
routing traces or placing components. This space
efficient design allows the development engineer
greater flexibility in placement of the modem within
the host system.

XE5692H AT Commands
The XE5692H uses "AT" commands for
configuration and control. This section describes
the AT command format and lists the commands,
registers and result codes.
Command Mode: The XE5692H 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.
The modem determines data rate of the host
equipment by measuring the width of the incoming
bits of the “A” and “T.”
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.
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.
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.
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 modem 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.
