2400bps Serial Input Component Modem
XE2401L
02-13-96
Description
Xecom's XE2401L component modem is a
complete 2400 bps data modem. Its
compact size and TTL level, serial interface
allows for quick integration into virtually any
new or existing design. The XE2401L
contains all of the circuitry required for
complete modem operation, including a user
transferable FCC Part 68 registration,
allowing direct connection to the Telephone
Network. The XE2401L was specifically
designed to provide industrial systems
manufacturers with a complete, highly
integrated, compact solution for adding data
communication to their products.
Features
• Small Size 1.08” x 2.28” x 0.42”,
• FCC Part 68 Registered, user transferable
• Data Transfer at 2400, 1200 and 300 bps
• Supported Protocols:
- CCITT V.22bis, V.22, V.21
- Bell 212A, 103
• TTL serial interface interfaces with
industry standard UART’s
• Single +5v supply
• Modem control with Industry standard “AT”
command set
• Standard package allows easy upgrades
to Fax (XE9624F) and 9600 bps (XE9601)

The XE2401L uses "AT" commands for
configuration and control. This section describes
use of the AT command format and lists the AT
commands, Registers and Result codes.
Modes of Operation
The "AT" commands have two operational
modes; Command Mode and Data Mode.
Data Mode: The XE2401L enters data mode
after it connects with a remote modem and issues
an appropriate "CONNECT" result code. In the
Data Mode the modem sends all data presented
on Transmit Data (TXD) to the remote modem
and puts data from the remote modem onto
Received Data (RXD). When the modem exits
data mode, it issues a "NO CARRIER" result
code.

FCC Instructions
This product complies with part 68 of the FCC Rules and Regulations. With each device shipped,
there is a label which contains, among other information, the FCC Registration Number and Ringer
Equivalence Number (REN) for this product. You must, upon request, provide this information to
your telephone company.
The mounting of this device in the final assembly must be made in such a manner as to preserve
the high voltage protection between the TIP/RING Connection and the rest of the system.
Typically, this may be accomplished by maintaining a minimum spacing .100 mils between the
TIP/RING Traces to the RJ-11C Jack and low voltage portion of the system. No additional circuitry
may be attached between TIP/RING and the telephone line connection, unless specifically allowed
in the rules.
The REN is useful to determine the quantity of devices you may connect to a telephone line and
still have all of these devices ring when the number is called. In most, but not all areas, the sum of
the RENs of all devices connected to one line should not exceed five (5.0). To be certain of the
number of devices you may connect to the line, as determined by the REN, you should contact the
local telephone company to determine the maximum REN for you calling area.
If your system causes harm to the telephone network, the telephone company may discontinue
service temporarily. If possible, they will notify you in advance. If advance notification is not
practical, you will be notified as soon as possible.
Your telephone company may make changes in its facilities, equipment, operations or procedures
that could affect proper functioning of your equipment. If they do, you will be notified in advance to
give you an opportunity to maintain uninterrupted telephone service.
If you experience trouble with this device, please contact XECOM at (408) 945-6640 for
information on obtaining service or repairs. The telephone company may ask you to disconnect
this device from the network until the problem has been corrected or until you are sure that the
device is not malfunctioning.
The device may not be used on coin service lines provided by the telephone company (this does
not apply to private coin telephone applications which use standard telephone lines). Connection to
party lines is subject to state tariffs.
