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.
1.2 Point-to-Multipoint Network A DN-2400E/EP point-to-multipoint point network consists of one DN-2400E/EP configured as the Base and up to 16 DN-2400E/EPs configured as Remotes. See Figure 1.2.1. In a point-to-multipoint network, the base should be connected to the main Ethernet network segment since all remote transmissions are sent to the base. Figure 1.2.1 DN-2400E/EP networks function as a MAC layer bridges, with no IP address filtering.

4.0 Installation 4.1 Mounting and Location The DN-2400E/EP case outline drawing is shown in Figure 4.1.1. The supplied antenna is hinged, allowing it to be set vertically with the case mounted either horizontally or vertically. The DN-2400E/EP case is designed for indoor use. It must be installed in a weather proof enclosure when used outdoors, such as a NEMA 4X enclosure. The enclosure must be made of plastic or other materials with low RF attenuation to avoid compromising antenna performance.
4.2 Connector and Terminal Block Figure 4.2.1 A conventional RJ-45 connector is provided on the DN-2400E/EP for the Ethernet connection, as shown in Figure 4.2.1. A “straight through” Ethernet cable should be used between the DN-2400E/EP and its host PC, etc. The RJ-45 connector incorporates two LEDs. The green LED indicates that an Ethernet link is established, and the amber LED indicates Ethernet traffic activity. On the DN-2400EP, this connector also supports IEEE 802.3af Mode B Power over Ethernet.
5.0 Configuration Options The following are the DN-2400E/EP parameters that can be configured by the user: Parameter Default Value TX Power 0 dBm (1.
can link. The Encryption key can be set over the air so it can be changed periodically if desired. Once an encryption key has been entered, it can be changed but it cannot be read back. Hop Duration - this sets the duration of the hop frame. The duration is set as a 12-bit value, 0.05 ms/count. Changing the hop duration must be followed by a MemorySave command to allow the change to persist through a reset or power cycle. A HopDuration change takes effect immediately.
6.0 DN-2400ESK and DN-2400EPSK Starter Kits It is highly recommended that a Starter Kit containing two DN-2400E or DN-2400EP units be purchased initially for installing a network. The Starter Kit enables you to set up a point-to-point Ethernet connection very quickly using the units default settings. The Kit also contains all the necessary hardware and software to make any changes to the default settings required by your application.
6.2 Getting Started The Starter Kit contains two Ethernet Bridge units. One unit is labeled “Base” and the second unit is labeled “Remote”. These are the default configurations set at the factory. They can be changed as explained below. The DN-2400E units are powered using the included power supplies. The DN-2400EP units can be powered either with the included power supplies or a from hosts that implements IEEE 802.3af Mode B Power over Ethernet. Figure 6.2.1 6.
6.4 Ethernet Port Connections Using the Ethernet cables provided in the Kit, connect one end of the cable to the back of each DN-2400E/EP and the other end to their respective Ethernet hosts. The green LED on the DN-2400E/EP Ethernet connector indicates that an Ethernet link is established, and the amber LED indicates Ethernet traffic activity. Figure 6.4.1 6.5 Applying Power to the Units Connect the power supply to the Base unit using the power supply connector on the rear of the unit.
Figure 6.6.1 Note: An additional configuration module with CD, power supply and serial cable can be order from RFM if the configuration module that comes with the Starter Kit is lost or damaged. 7.0 DN-2400E/EP Configuration Utility Create a file folder on the PC and copy the DNWizard.exe utility from the CD supplied with the DN-2400E/EP Starter Kit into the folder. DNWizard.exe requires no installation and can be simply run.
Click on the Connect button in the main window. The Comm Port Settings dialog box shown in Figure 7.0.2 will appear. Click on the OK button to establish a connection with the DN-2400E/EP. Figure 7.0.2 Figure 7.0.3 As soon as the serial connection is established, the Current Settings information on the left side of the main window and the information on all configuration tabs will be populated, as shown in Figure 7.0.3. www.RFM.com © 2011 by RF Monolithics, Inc.

Figure 7.0.4 Note that all DN-2400E/EP wireless bridges ordered as single units outside of the Starter Kit are shipped configured as Remote units. One DN-2400E/EP in each network must be configured as a Base. All traffic to and from other bridges in the DN-2400E/EP network will flow through the base. Figure 7.0.4 shows a DN-2400E/EP being reconfigured from a Remote to a Base.
Figure 7.0.5 The System configuration tab is shown in Figure 7.0.5. In France and some other regions, only specific Frequency Band settings are compatible with local radio regulations. This is discussed in Section 5. The Auth Mode drop down control allows the selection of Any Remote (default), or By Base Table. Selecting By Base Table on the Base unit allows only the remote MAC addresses input on the Auth List tab to join with the Base. www.RFM.com © 2011 by RF Monolithics, Inc. Technical support +1.678.
Figure 7.0.6 The read only Status tab shown in Figure 7.0.6 displays information about the DNT2400 radio embedded in the DN-2400E/EP, plus related network information. Figure 7.0.7 www.RFM.com © 2011 by RF Monolithics, Inc. Technical support +1.678.684.2000 E-mail: tech_sup@rfm.
When By Base Table is selected for Auth Mode on the System tab of a Base, only remotes with their MAC addresses loaded on the Auth List tab shown in Figure 7.0.7 will be allowed to join with the Base. Figure 7.0.8 Figure 7.0.9 The 0x0002E0 MAC address of the DN-2400E/EP in Figure 7.0.8 is shown loaded in the Approved Addr0 field above. The 0xFFFFFF in the rest of the approved address fields indicates no assignment. www.RFM.com © 2011 by RF Monolithics, Inc. Technical support +1.678.684.
