1.0 DN-2400E and DN-2400EP Introduction
The DN-2400E and DN-2400EP provide robust wireless 10 BaseT Ethernet bridge connections between
a base and one or more remote units. The DN-2400E is designed to be powered from an external DC
power supply. The DN-2400EP is designed to be powered from an external DC power supply or an IEEE
802.3af Mode B Power-over-Ethernet host. The DN2400E/EP wireless link is implemented using RFM’s
DNT2400 Frequency Hopping Spread Spectrum transceivers. The DN-2400E/EP features RF transmis-
sion rates up to 500 kbps and transmitter power levels up to 100 mW EIRP using a 2 dBi antenna.
The DN-2400E/EP is supplied with a 2 dBi dipole antenna and a universal wall-plug power supply,
plus an Ethernet cable. Optional directional antennas are available to extend operating range. The
DN-2400E/EP are shipped from the factory configured as “Remotes”. All DN-2400E/EP factory default
settings can be changed as needed for a specific application, as described in Sections 5 and 7 of this
guide. The DN-2400E and DN-2400EP bridges are well suited for Ethernet sensor networks and data
networks carrying light to moderate traffic.
Key Features of the DN-2400E/EP Ethernet Bridges include:
- Nine 2.4 GHz Frequency Subbands Support License-free Operation World-wide
- RF Data Rate Configurable from 38.4 to 500 kbps
- Transmitter Power Configurable from 1.58 to 100 mW EIRP (2 dBi Antenna)
- Point-to-Point or Point-to-Multipoint Operation
- Optional 128-Bit AES Encryption and Authentication Modes
- Wide DC Power Supply Operating Voltage Range
- 10 BaseT Ethernet Port, with IEEE802.3af Mode B PoE capability on DN-2400EP
- Serial Port for Configuration
- Rugged Aluminum Enclosure can be Mounted Horizontally or Vertically
- FCC, Canadian IC Certified and CE Marked for Unlicensed Operation
1.1 Point-to-Point Network
DN-2400E/EP units can operate in either point-to-point or point-to-multipoint networks. A DN-2400E/EP
point-to-point network consists of one DN-2400E/EP configured as the Base and one DN-2400E/EP con-
figured as a Remote, as shown in Figure 1.1.1. In a point-to-point network, it does not matter which de-
vice is connected to the main Ethernet network.
