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)

Power Management Specifications/ Issues
The XE2401 has an integrated, advanced power management capability. If no activity is detected
on the RXD, DTR, or RI lines the modem will automatically go into a smart power down mode. In
this mode power consumption is typically less than 60 milliwatts.
