SEM910 Introduction The SEM910 family of products from Cirronet™ Incorporated provides wireless Ethernet connectivity between networks located more than 5 miles apart. Built around the WIT910 frequency hopping spread spectrum data modem, SEM products provide a 10/100BaseT connection to Ethernet networks. SEM products operate in a point-to-point mode or a point-to- multipoint mode using a star configuration.
IP addresses, configuring one SEM as the master and connecting the antenna, power and Ethernet cable. While the operation of the SEM910/D and SEM910X/DX is the same, the installation and connection is slightly different. Please refer to the appropriate section below for connection and installation of your product.
The 10/100BaseT Ethernet connector is the standard RJ-45 connector located on the front of the SEM910D and the rear of the SEM910. The SEM is set up to use a straight through cable to connect to a PC. If a straight through cable is used to connect the SEM to other devices through a hub, the SEM must be connected to the uplink port on the hub.
SEM910 SEM910X/DX Figures 4, 5 & 6 show the connectors and LEDs on the SEM910X & SEM910DX radios. Figure 7 illustrates the remote radio assembly. Connection between the SEM910X and SEM910DX enclosures and the remote radio assembly is made through the 15-terminal connector on the front of the radios.
SEM910 The remote radio assembly has mounting holes to secure the antenna. The antenna is attached to the remote radio through the included 24-inch RF cable. If the antenna is not to be mounted on the remote radio assembly, connection between the remote radio and the antenna must be made with high-quality , loww-loss RF cable.
SEM910 Complete the assembly by placing the connector in the slot in one of the shell halves. Install the two retaining screws on both sides of the shell and through the holes on both sides of the connector; place the other shell half over the connector so the connector lies in the shell slot.

SEM910 If a pin is accidentally installed in the wrong connector location, simply loosen the screw, remove the pin, re-insert it into the proper location hole and tighten the screw. Use the following color code to insert the pins into the connector:...
0.0.0.0 to have the slave SEM obtain its IP address from the DHCP server. IP Hunter Utility The SEM910 CD has a device detection and IP setting utility named IP Hunter. This utility will detect all Cirronet Ethernet devices on the local network, even those with no IP address. For those units without an IP address, IP Hunter can set the IP address and then open a browser session with that device to allow for further configuration.

SEM910 Open IP Hunter by double-clicking on the file iphunter.exe on the SEM910 CD. The following screen will appear. Click on the Search button to begin the search for Cirronet devices. Only Cirronet Ethernet devices will be displayed as shown below.
Page 15
Enter the desired IP address and the default netmask will automatically be entered as shown below. A new Host Name may be entered if desired; however, the MAC Address cannot be changed. Click OK and the IP address will be entered in the SEM910 and will be displayed in the IP Hunter window as shown below.
SEM910 HTML Setup Once an address has been assigned, double-click on the IP number to launch an HTML setup session in a browser window. The login screen will display as shown below. Enter the default Username, “admin” and the default Password, “Cirronet” (case sensitive).

This dialog allows the user to change the Hostname, set the Default Route, enter DNS entries or change the Outmax (upload/download ratio for the radio) setting. If the SEM910 is to transmit data to devices not on its subnet, a default router must be specified. To set the default routing address, enter it in the Default Route field.

Enable IP address Control This dialog is used to designate the Allowed IP addresses from which the SEM910 will accept a telnet session request. Simply enter an IP address in the “Allowed IP address” field and click “Add IP address.
SEM910 Access Control Users This dialog allows the modification of logins and the ability to add new users. Note: Click on Save Settings to store the system configuration changes in non-volatile FLASH memory. The user may either click on “Reset” to reboot the processor, click on “Logout” to end the browser session or simply close the browser window.
Note: Failure to save and reset will result in the factory defaults being used. Filtering The SEM910 includes provision for filtering of multicast and broadcast packets. In many networks, there is sufficient multicast and/or broadcast packets to slow the overall performance of the SEM.
SEM products use MAC-layer addresses to learn on which network segment a device is located. A master SEM can connect up to 15 remote slave SEMs. The SEM910 is a single channel device with an over-the-air data rate of 172.8Kbps. The radio modems in the SEMs are factory configured with optimum settings for typical point-to-point applications.
SEM910 the master automatically configures the radio in the master as a base radio. Similarly, configuring a SEM as a slave automatically configures the slave radio as a remote radio. When a master SEM is powered on, it becomes active immediately, even if no slave SEMs are detected.
SEM910 If the application has more slave devices, or if it is desirable to increase the throughputs of the slaves at the expense of the master SEM, contact Cirronet technical support for more details. Co-located Networks The radio architecture in the SEM allows multiple networks to be located in the same area without interfering with each other.
SEM910 SEM Command Set The SEM supports a series of commands that allow for configuring the Ethernet interface as well as the radio parameters of the on-board WIT910. These commands can be entered during a telnet session or by using the WinSEM24 utility when the prompt is displayed.
