XE9624F/XE9624FS XECOM\5
AT Commands
The XE9624F and XE9624FS use the Hayes "AT" commands for configuration and control.
Extensions to the AT commands support fax operation. The following section describes how
to use the AT command format and lists the AT commands, Registers and Result codes
used to control modem operation.
Modes of Operation
The "AT" commands have three operational modes; Command, Fax and Data Modes.
Data Mode: The XE9624F/FS enters data mode after it makes a connection with a
remote modem and issues an appropriate "CONNECT" result code. In the Data Mode
the modem sends all data on the Transmit Data line to the remote modem and puts
data from the remote modem onto the Received Data line for the host equipment.
When the modem exits data mode, it issues a "NO CARRIER" result code.
Command Mode: The XE9624F/FS enters command mode on power-up, reset, a lost
connection, or receipt of an escape code. When in command mode, the modem
accepts command line instructions from the host on transmit data. More than one
instruction may be placed on each command line. Appropriate result codes are
returned to the host on received data. The AT commands allow the host to configure
the modem for a specific application.
Fax Mode: The XE9624F/FS enters fax mode after it receives the AT+FCLASS=1
command. In fax mode commands and responses are issued at 19,200 bits per
second; the character format is 8 bits no parity. The modem accepts Class 1 fax
commands only while in the fax mode. The A/, ATO, AT&T and escape commands are
not valid in fax mode.
Command Line Format
Command lines issued to the modem follow a strict format. Each command begins with the
prefix AT. The command line is stored in the command buffer and executed upon receipt of
a carriage return. Untilexecuted, the command line can be editied with the backspace key.
Command Prefix - Each command, except for the A/ command, begins with the AT prefix.
The "A" and "T" may be either both caps or both lower case but cannot be of different cases.
The prefix identifies the speed and parity of the commands sent to the modem by the host.
Speed is determined by measuring the width of the incoming bits. Parity is determined by
comparing the parity bit of the "A" and the "T." Result codes are sent at the speed and
parity determined by the prefix.
Page 6
6/XECOM XE9624F/XE9624FS
Command Line - Commands may be joined in a single command line up to 40 characters
long. Commands are executed in the sequence they appear. Spaces may be inserted into
the command line to improve readability. Spaces do not fill space in the command buffer. A
carraige return terminates the command line and causes the commands to be executed.
Register S3 allows the user to select a character other than a carriage return to terminate the
command line.
Command Buffer - No more than 40 characters, including the AT prefix, may be loaded into
the command buffer. If the command buffer overflows, the modem issues an "ERROR"
result code and commands are not executed.
Command Line Editing - The backspace can be used to edit the command line before it is
executed. Hiting the backspace key, or Control and H simultaneously on some systems,
erases the previous character in the command line. All of the characters in the command
line can be erased escept for the "A" and "T." Register S5 allows the user to select another
character other than a backspace to edit the command line.
Re-Execute Last Command - The A/ command causes the modem to reexecute the last
command line. This is the only command which does not require the "AT" prefix.
Ommitted 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 maybe entered while in data mode to
switch the modem into command mode while on line. The escape character, set by Register
S2, must be entered 3 times in succession within a 1 second guard time to execute the
escape. The default escape sequence is "+++."
Result Codes - The modem issues a result code after each action. Result codes may be
provided as full words, numeric codes or may be disabled all together. Each result code
ends with a carriage return when numeric resul codes are chosen. When full word result
codes are chosen, a Line feed and Carriage Return preceed abd follow each result code.

FCC Instructions
FCC Registration Number: DWEUSA-20716-MM-E
Ringer Equivalence: 0.8B
This product complies with Part 68 of the FCC Rules and Regulations. Each device shipped includes a label which contains the FCC
Registration Number and Ringer Equivalence (REN). If requested, this FCC information must be provided to the telephone
company. A registration label must be affixed to the cabinet's exterior for each device mounted within a closed assembly.
Ringer Equvalence (REN) is used to calculate the number of devices you may connect to one telephone line and still have all of the
devices respond to an incoming call. Typically, the sum of the RENs of all devices connected to one line should not exceed five
(5.0). Contact your local telephone company to determine the maximum REN for your area.
Mount this device in the final assembly so as to prevent exposure to any hazardous voltages in the system and to preserve the high
voltage protection between Tip/Ring and the rest of the system. Installation must provide adequate separation and restraint of cables
and cords. Xecom recommends maintaining a minimum of .100 inches between the Tip and Ring traces and all other circuits. No
circuitry may be added between Tip/Ring and the telephone line connection unless specifically allowed by the rules.
This device requires use of an RSOC RJ-11C jack for the telephone line connection. The jack selected must be certified to meet
FCC Part 68 subpart F requirements.
If you experience trouble with this device, contact XECOM at (408)945-6640 to obtain service. There are no repairs the customer
may make to this device. If your system causes harm to the telephone network, the telephone company may discontinue service
temporarily until the problem has been corrected or it is demonstrated that the device is not malfunctioning. If possible, you will be
notified in advance that service is being discontinued. If advance notice is not practical, you will be notified as soon as possible.
Your telephone company may make changes to their facilities, equipment, or operation that affect proper functioning of your
equipment. You will be notified in advance of such changes to give you the opportunity to maintain uninterrupted telephone service.
This device cannot be used on coin operated telephone lines provided by the telephone company. Connection of this equipment to
party lines is subject to state tariffs.
Any one using this device for fax transfer must include sender identification information as required in the Telephone Consumer
Protection Act of 1991. The Telephone Consumer Protection Act of 1991 makes it unlawful to send a fax without clearly identifying
the fax sender (business or individual) and the number of the transmitting fax machine. This information may be provided either on
the first page of the fax or in the top or bottom margin of each page. The number listed may not be a 900 number or other number
for which charges exceed local or long distance transmission.
The final assembler must provide these FCC instructions to the end user of the equipment.
