Page 2 Digi TransPort® WR21 Installation Guide Special notes on safety for wireless routers Digi International products are designed to the highest standards of safety and international standards compliance for the markets in which they are sold. However, cellular-based products contain radio devices which require specific consideration. Please take the time to read and understand the following guidance. Digi International assumes no liability for an end user’s failure to comply with these precautions. Wireless routers incorporate a wireless radio module. Users should ensure that the antenna(s) is (are) positioned at least 1 meter away from themselves and other persons in normal operation. When in a hospital or other health care facility, observe the restrictions on the use of mobile phones. Do not use the unit in areas where guidelines posted in sensitive areas instruct users to switch off mobile phones. Medical equipment may be sensitive to RF energy. The operation of cardiac pacemakers, other implanted medical equipment and hearing aids can be affected by interference from cellular terminals such as the wireless routers when places close to the device. If in doubt about potential danger, contact the physician or the manufacturer of the device to verify that the equipment is properly shielded. Pacemaker patients are advised to keep the wireless router away from the pacemaker while it is on. Wireless routers must NOT be operated on aircraft. The operation of wireless appliances in an aircraft is forbidden to prevent interference with communications systems. Failure to observe these instructions may lead to the suspension or denial of cellular services to the offender, legal action, or both. As with any electrical equipment, do not operate the unit in the presence of flammable gases, fumes or potentially explosive atmospheres. Radio devices should not be used anywhere that blasting operations are taking place. Wireless routers receive and transmit radio frequency energy when power is on. Interference can occur if used close to TV sets, radios, computers or inadequately shielded equipment. Follow any special regulations and always power off your unit wherever forbidden or when it may cause interference or danger. SOS IMPORTANT! - Wireless routers operate using radio signals and cellular networks cannot be guaranteed to connect in all possible conditions. Therefore, never rely solely upon any wireless device for life critical communications. Warning: For environments where the temperature is 55° C or above, this device must be installed in a restricted access area.

LED Status Indicator - WWAN (Wireless Network) - Flashes to show which network mode the unit is operating in: • Off - no service • 1 blink - GPRS mode • 2 blinks - EDGE mode • 3 blinks - UMTS mode • 4 blinks - HSDPA mode • 5 blinks - HSUPA mode • On steady - CDMA mode 5. LED Status Indicator - SIGNAL. • 0 LEDs illuminated: < -113 dBm (effectively no signal) • 1 LED illuminated: >= -112 dBm and = -86 dBm and = -70 dBm and Mobile > CDMA Provisioning. Page 12 Digi TransPort® WR21 Installation Guide 4.2.1.1  CDMA Provisioning CDMA provisioning is different from GSM since CDMA (in most cases) does not use a SIM card. The CDMA modem provisioning process creates a CDMA data connection to the mobile carrier network. This authenticates the modem and retrieves account information which is written to flash memory on the modem module itself, not the Digi’s configuration file. As the mobile account information is stored on the CDMA module, performing a factory reset on the unit will not remove provisioning information from the CDMA module. Important points: • The modem must be provisioned on the network before it will communicate. • The modem must be in coverage area of the native carrier. It cannot be roaming. • There must be sufficient signal strength available to provision the modem. • Always use MIP Profile 1 for manual provisioning unless specified otherwise by your carrier or Digi Technical Support. 4.2.1.2  Automatic vs. Manual Provisioning There are two types of CDMA provisioning: Automatic and Manual. This varies between carriers and even within carriers. Settings in the Web Interface vary based on carrier plan. Below are examples for Verizon Wireless and Sprint: Verizon Wireless always uses Automatic. This means that no further settings are required in the Web Interface - simply press Start in the Automatic section and leave the fields blank. Sprint has two types of plans, Vision for standard Internet connections and DataLink for private IP plans: 1. Sprint Vision uses Automatic provisioning. There are three fields of information that may need to be populated in the Automatic screen. Check with Sprint for correct values (if required). 2. Sprint DataLink requires Manual provisioning. The required fields in the Web Interface vary based on plan and type of embedded modem. As noted above, always use MIP Profile 1 unless otherwise specified by your carrier or Digi Technical Support. Check with your carrier for information about the type of provisioning required and what, if any, data is required to be entered. For more information on configuring the unit, please refer to the Digi TransPort User Guide which is available at www.digi.com. 4.2.2  Cellular: GSM To configure the Wireless WAN/mobile interface on non-CDMA routers (GPRS/UMTS/HSPA), please refer to the Application Guide “QN02 - Configure the wireless WAN (PPP) interface” which can be found on the Digi Support site (http://www.digi.com/support/). It is also essential to configure a dead link detection mechanism for routers using a Wireless WAN/mobile interface (such as GPRS/HSDPA/CDMA). Please refer to the Application Guide “AN07 - Wireless - Wide Area Network (W-WAN) Problem Detection and Recovery” which can also be found on the Digi Support site (http://www.digi.com/support/). Page 13 Digi TransPort® WR21 Installation Guide 4.3  Command Line Interface (CLI) In order to configure the unit serially, ensure that the unit is connected to a PC (as outlined in Step 4 page 10 of the Installation section). Also, terminal emulation software (such as HyperTerminal) will be required. 4.3.1  CLI Notes • To view the current configuration settings, enter the command CONFIG C SHOW. • To save changes made to the unit, enter the command CONFIG 0 SAVE. • All entered commands will take effect immediately. 4.3.2  Communication Settings Step 1) Configure the following settings for the unit: COM Port: [select the appropriate port; typically COM1] Baud Rate: 115200 Data Bits: 8 Stop Bits: 1 Parity: No Parity Flow Control: None Step 2) Ensure the connection is active by entering the command AT. If the device is functioning properly, it will return the response OK. Step 3) Ensure the COM port is setup correctly by entering the command ATI5. 4.3.3  Network Settings To configure the unit with an IP address as part of an existing network, use the commands below. Note: The DHCP server will still operate unless it is disabled. Command ETH 0 IPADDR XXX.XXX.XXX.XXX ETH 0 MASK XXX.XXX.XXX.XXX Description Sets the Eth 0 IP address Sets the Eth 0 subnet mask As an example, to assign the IP address 192.168.10.254/24, the following commands would be entered: ETH 0 IPADDR 192.168.10.254 ETH 0 MASK 255.255.255.0 Note: When setting the mask to the above 255.255.255.0 value, it will not appear in the output of the CONFIG C SHOW command as it is a default value. Page 14 Digi TransPort® WR21 Installation Guide To stop the DHCP server from serving addresses, use the following command: Command DHCP 0 IPMIN X Description Removes the minimum IP address that will be server via DHCP, disabling the DHCP server As an example, to stop the DHCP sever from DHCP requests, enter the command DHCP 0 IPMIN !. The ! variable is used to remove a value or set it back to its default. To retain the DHCP server, but on a different subnet, the following parameters will need to be configured: Command DHCP 0 IPMIN x.x.x.x DHCP 0 IPRANGE DHCP 0 GATEWAY x.x.x.x DHCP 0 MASK x.x.x.x DHCP 0 DNS Description Minimum IP address to assign, the start of the DHCP pool The number of IP addresses in the DHCP pool The IP gateway address the DHCP clients should use (normally this router’s LAN IP address) The subnet mask DHCP clients should use The DNS server DHCP clients should use For more information on CLI commands, visit http://www.digi.com/support/ and view the various reference manuals available. Page 15 Digi TransPort® WR21 Installation Guide 5 Troubleshooting 5.1  Troubleshooting Resources There are several resources available to you for support of your Digi product or resolving configuration difficulties at Digi’s Support site, http://www.digi.com/support/. Try these troubleshooting steps to eliminate your problem. After working through these steps and your problem is not solved, try the resources listed below. 1. Digi’s Support knowledge base: http://www.digi.com/support/kbase. 2. Digi TransPort support documents: http://ftp1.digi.com/support/documentation/transport/technicalnotes.htm. 3. If the knowledge base or support forums do not have the information you need, fill out an Online Support Request via: http://www.digi.com/support/eservice/login.jsp?p=true. You will need to create a user account if one is not already set up. When submitting a support request, please include a copy of the debug.txt file from the unit’s flash. This will greatly improve the quality of the initial response you receive. Without this file, it is often very difficult for the support team to provide accurate answers to your queries. For instructions on how to download the debug.txt file from the unit, view the online document “QN24 Extracting the debug.txt file from a Digi TransPort or Sarian router”. 5.2  Unable to open the Web Interface Ensure that the LAN cable is properly connected to the LAN port and that the “LAN” status indicator on the front of the unit is illuminated. If it is not, then there is a problem with either the LAN cable or the device it is connecting to. If the status indicator is illuminated, check that the PC can communicate with the unit. To do this, open the Command Prompt window on your PC and enter the command “ping 192.168.1.1”. If you do not get a response, then the problem could be one of the following: • The IP address of the unit has been changed from its default of 192.168.1.1. Use the Digi TransPort Connection Wizard (which can be downloaded from the Support area at Digi.com or the Digi Device Discovery Tool). It can usually discover the unit on a network as long as the unit’s firewall has not been enabled. • PC IP configuration. The PC’s LAN interface that is connected to the unit should be configured to “Obtain an IP address automatically”. If required, the Digi TransPort Connection Wizard can be used to configure the PC. • Check the PC’s LAN connection and any LAN device (e.g. Ethernet switch) that is used to interconnect to the unit. • Refresh the PC’s IP settings by opening a command window and enter “ipconfig /release” then “ipconfig /renew”. • ARP resolution. Clear the PC’s ARP cache with the command “arp –d *”, then retry the ping command. If you do get a response but are unable to view the Web Interface, then there is most likely a problem with your web browser configuration. 5.3  Unable to log in to the Web Interface Access to the unit can be achieved via any of the asynchronous serial ports. Connect your PC to the unit using a “straight through” RS232 serial cable. This will allow you to change the configuration via the Command Line Interface (CLI). Please refer to the Digi TransPort User Guide for information on how to use the CLI. The User Guide can be downloaded from the Digi Support site. If you have further questions about your product please contact Digi Technical Support (see page 2 for contact information).
