ADSL-2401D.S

Industrial ADSL modem with integrated serial port server



Introduction

The MuLogic ADSL-2401D.S is an ADSL2+ modem-router with Ethernet port and serial port.
The serial port is connected with an integrated serial port server which can be accessed via the LAN and the DSL port.

The modem is designed for industrial applications and can be powered from any 9 to 36 Volts or 18 to 60 Volts power source. The ADSL-2401D.S operates over a wide temperature range.
Features

  • Din-Rail or panel mounting.
    •
* N.b: For public networks in Germany the mode is always Annex B.

Application Areas

Remote access applications
The ADSL-2401D.S is intended for remote access to terminal units with a serial port or Ethernet port.
The integrated Serial Port Server allows for direct connection with the remote serial port, either by means of a "com port redirector" a direct IP socket connection (e.g. "WinSock") or another ADSL-2401D modem.
 
For secure operation, access to the serial port via the internet can be restricted to pre-defined IP addresses, making it impossible to access the port from unknown locations.

The ADSL-2401D can be used to replace Dial-up and leased line modems and offers high speed Ethernet communications while maintaining support of serial communication. This allows for easy migration to the use of remote terminal units with Ethernet interface and other devices such as remote surveillance cameras while maintaining the serial port connection.

Replacing Dial-up modems for the ADSL-2401D.S cuts the costs for the telephone calls made for each session. The ADSL-2401D.S can be installed without the need for replacing the telephone line. Just add ADSL service on the existing line.




Configuration and access control
The ADSL-2401D.S can be controlled and/or configured in multiple ways:
  • Local serial command port.
  • Web browser via local Ethernet port.
  • Web browser via the DSL network.
  • Telnet via local Ethernet port.
  • Telnet via the DSL network.
  • SNMP via local Ethernet port.
  • SNMP via the DSL network.
    •
Access restrictions can be set for each protocol for both local LAN port or access via the DSL network.

Power supply
The ADSL-2401D.S modems are equipped with an internal galvanic isolated power supply. Two voltage ranges are available:
  • 9-36Vdc/12-26Vac.
  • 18-60Vdc/24-30Vac.
    •
For mains power operation (100..240Vac) an external power adapter or power supply is used.

Extended temperature range
The modem can be used in many environments. It is suitable for operating at ambient temperatures ranging from -30°C to +70°C.
