Power Management:
The XE1414A has an integrated power management capability. If no activity is detected on
the RXD, DTR, or RI the modem will, within 5 seconds, automatically go into a smart sleep mode. In this mode
power consumption is typically less than 50 milliwatts.

PIN NAME DESCRIPTION
3 RXD Serial data output to the DTE (i.e. external UART). A logic "high" represents a
"mark" and a logic "low" represents a "space", TTL.
9 \DTR Data Terminal Ready, input, active Low, TTL. The function of this pin is set by
the &D command. Normally the modem ignores DTR.
11 \CTS Clear to Send, output, active Low, TTL/CMOS. This pin regulates the flow of
data from the DTE during hardware flow control.
13 TXD Serial data input from the DTE (i.e. external UART). A logic "high" represents a
"mark" and a low represents a"space", TTL.
14 \RTS Request to Send, input, active Low, TTL. This signal regulates the flow of data
from the modem during hardware flow control.
16 \RI Ring Indicator, output, active Low, TTL. When low indicates the modem is
receiving a ring signal.
19 TIP Tip connection to the phone line(RJ11 pin3) from the internal DAA.
20 RING Ring connection to the phone line(RJ11 pin4) from the internal DAA. Caution:
21 GND Ground (0 volts)
22 AMP Audio output function is determined by L & M commands and the value in
register S22. This output can drive a 300 ohm load.
30 OH Oh is an active low output from the modem. Oh goes high when the modem is
"off-hook." This signal can be used to drive and external relay to switch line
usage between the modem and a handset.
36 RESET Hardware reset pin, active High, TTL. Use of an external reset is not
recommended. When not used Reset should be left open. Any signal applied to
Pin 36 must remain high for a minimum of 100 milliseconds.
38 \DCD Data Carrier Detect, output, active Low, TTL/CMOS. Function is set by the &C
command and the value in register S21.
39 \DSR Data Set Ready, output, active Low, TTL/CMOS. Function is set by the &S
command and the value in register S21.
40 Vcc +5 Volt power

AT Commands
The XE1414A uses "AT" commands for modem
configuration and control. Extensions to the AT
commands support fax and voice.
Modes of Operation
The XE1414A has three operational modes; Command,
Fax and Data.
Data Mode: The XE1414A enters data mode after it
establishes a connection and issues a "CONNECT"
result code. In the Data Mode the modem sends all
signals on Transmit Data to the remote modem and puts
data from the remote modem onto Received Data for
the host equipment. When the modem exits data mode,
it issues a "NO CARRIER" result code.
Command Mode: The XE1414A enters command
mode on power-up, reset, loss of the 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.
Fax Mode: The XE1414A enters Class 1 fax mode on
receipt of AT+FCLASS=1 and Class 2 fax mode on
receipt of AT+FCLASS=2. 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
fax commands only in 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. Until
executed, the command line can be editied with the
backspace key.
Command Prefix - The "A" and "T" of the command
prefix may be both capitilized or both lower case but
cannot be of different cases. The prefix identifies the
speed and parity of the host. The modem determines
speed by measuring the width of the incoming bits.
Parity is determined by comparing the parity bits of the
"A" and "T." The XE1414A normally sends result codes
at the speed and parity determined by the prefix.
Command Line - Multiple commands may be placed in
a command line. Commands are executed in the
sequence they appear. Spaces may be inserted to
improve legibility without filling space in the command
buffer. A carriage 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 - Only 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. Hitting the backspace key, or
Control and H simultaneously on some systems, erases
the previous character in the command line. All of the
characters can be erased except for the "A" and "T."
Register S5 allows the user to select a character other
than a backspace to edit 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.
Ommitted Parameters - Most commands include a
parameter which determines the command function.
When this parameter is omitted from the command
string, it is assumed to be a 0.
Escape Characters - A three character escape
sequence maybe entered while in data mode to switch
the modem into command mode while remaining on line.
The escape character, set by Register S2, must be
entered 3 times in succession 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 result codes are chosen. When full word result
codes are chosen, a Line Feed and Carriage Return
precede and follow each result code.

FCC Instructions
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.
