IS08004 Setup and Configuration of Leased Line Modem with NxLink (Vector) INFORMATION SHEET 1 INTRODUCTION This document provides setup and configuration information for leased line modems. The leased line modems, with a Nautel NxLink Ethernet interface module will provide constant communication with your Vector NDB from a remote location, which allows you to remotely control the NDB as well as receive and monitor important data from the NDB. Figure 1 shows the connection diagram for a leased line setup. The modem on the remote (NDB) side is located inside the front door of the transmitter and is connected to remote interface PWB A3 using RS-232 male-to-female cable. The modem on the host side is connected to the NxLink using RS-232 male-to-female cable. The NxLink is then connected to a host PC, using a cross-over Ethernet cable or through a hub. 2 SETUP AND CONFIGURATION 2.1 Modems Configure each modem for leased line operation. One modem will be configured as originate or the dialing out modem. The other modem will be configured as the answer or receiving modem. It makes no difference which side is configured as originate or receive. This procedure configures the host modem as originate and the remote modem as answer. (a) On the NDB side, disconnect the cable between the modem and remote interface PWB A3. Connect an RS-232 female-to-male modem cable between your PC (or laptop) and the COM port of the modem.

Figure 2: COM Properties (b) Open HyperTerminal (see Figure 2) or similar program and set up the serial settings as follows: Baud Rate: 19200 Data Bits: 8 Parity: None Stop Bits: 1 Flow Control: None (c) When the connection is established, type the following on the screen within ten seconds: +++AT&F (press Enter) (d) To see typed text on the screen, go to File, Properties, Setting, ASCII Setup (see Figure 3). Check the Echo typed characters locally checkbox. (e) Set the initialization string for each modem by entering the following: Originate modem (host side modem): ATS0=1S2=128S9=0%C0\Q0\N3$MB 33600$SB19200$EB0&E12V0X7\V0 E0+DCS=0,0 (press Enter) AT&L1&D0%DC1&W0 (press Enter) Answer modem (remote side modem): ATS0=1S2=128S9=0%C0\Q0\N3$MB 33600$SB19200$EB0&E12V0X7\V0 E0+DCS=0,0 (press Enter) AT&L2&D0%DC1&W0 (press Enter) NOTE Make sure to enter all lines exactly as shown. Each time you press Enter the cursor should return to the beginning of the line and display a 0. The 0 indicates that the line of string was successfully entered. You may want to type the string in a word processing program, then use copy and paste. If you make a mistake simply re-type +++AT&F and press Enter. You may need to reboot the modem.

Figure 3: ASCII Setup (f) After each modem has been set up, reconnect them to their device using the RS-232 cables provided. Connect the originate modem to the NxLink and the answer modem to the NDB. Connect the modems to the leased line phone jack. (g) The modems should automatically dial up and connect to each other. It will take about 50 s for the modems to connect. 2.2 NxLink The NxLink is preconfigured for DHCP. This means that it will automatically be given an IP address. If connected to a DHCP configured network, you will need to set the baud rate to match the modem and you should give the NxLink a fixed IP address. This can be done using a NetBurner discovery tool. You may leave the NxLink and the host PC with the DHCP setting, but you may be required to search for it each time the NxLink is rebooted. (a) Connect your laptop to the NxLink s Ethernet port using a cross-over Ethernet cable or through a hub. Apply power to the NxLink using the supplied adapter. Configure the NxLink using the discovery tool [see step (b)] or using HyperTerminal [see step (c)]. (b) Navigate to the discovery tool at the following web page (see Figure 4): http://www.netburner.com/support/public_ downloads.html (NetBurner IPSetup Tool). Open the application. It should automatically search and find the NxLink. If not, click Search Again. Once found, click on the unit in the Select a Unit screen. The NDK Settings will now display the IP address, etc. of the NxLink. The IP address at this point should be 0.0.0.0. Change the NDK Settings as follows and press Set: IP: 192.168.1.2 Network Mask: 255.255.255.0 GateWay: 192.168.1.1 Setup & Configuration Leased Line Modem with NxLink Page 3 IS08004 Issue 1.0
Figure 4: NetBurner IPSetup V2.0 Change the baud rate to 19200. The IP address is not critical and can be changed as needed. Pressing Search Again should find the NxLink with the new IP address. (c) Configure the NxLink using HyperTerminal. Connect an RS-232 female-to-female null modem cable from your computer to Port 0 of the NxLink. Open up HyperTerminal and set up the COM port as follows: Baud Rate: 115200 Data Bits: 8 Parity: None Stop Bits: 1 Flow Control: None (d) Connect power to the NxLink. A message should appear Waiting 10sec to start A to abort. Type A to display the following message: Netburner SB72EX Monitor V1.0 Jul 2 2004 12:06:03 HELP for help nb> (e) Type Setup and press enter. The following menu will appear: MAC address=00-03-f4-02-58-69 1.)IP Address =0.0.0.0 2.)IP Mask =255.255.255.0 3.)IP Gateway =0.0.0.0 4.)TFTP Server=0.0.0.0 5.)TFTP File = 6.)Baudrate =115200 7.)Wait =10 8.)Boot to Application 9.)Exceptions CauseReboot A.)DNS Server =0.0.0.0 B.)Boot Port =0 C.)Switch to Quiet Boot 1-B to change, S to save, X to exit (f) Item 6 sets the NxLink s baud rate. Type 6 and press enter. Now type 19200 and then press enter. The same menu should re-appear with the new baud rate. Perform the same steps to change the IP address 1 and the IP Gateway 3. Finally Type S and press Enter to save the change. The following message will appear: Page 4 Issue 1.0 Setup & Configuration Leased Modem with NxLink IS08004

NOTE Skip step (h) if the NxLink and host PC are set up for DHCP. (h) On your PC navigate to the Internet Protocol (TCP/IP) Properties page (see Figure 5): in Windows XP, click on Start, Control Panel, and Network Connections. Right click on the local area connection and select Properties in the pop-up menu. On the Local Area Connections Properties page scroll down and click on Internet Protocol (TCP/IP) then select Properties. Select Use the following IP address and configure as follows. IP address: 192.168.1.3 Subnet mask: 255.255.255.0 Default gateway: 192.168.1.1 The IP address is not critical, but make sure the Default gateway is the same for both the NxLink and the PC.

2.3 Completion of Setup Setup for the modems and NxLink is complete. Navigate to your browser and enter the IP address of the NxLink (e.g., 192.168.1.2). The NxLink Remote Control page will open (see Figure 6). Figure 6: NxLink Remote Control page Page 6 Issue 1.0 Setup & Configuration Leased Line Modem with NxLink IS08004
3 TROUBLESHOOTING If the leased line modems are not communicating properly, check the following: 3.1 Connections Check for loose cables and connections. Ensure that modems, NDB and NxLink have power. 3.2 Signal Verify that the NDB side modem s TR LED is on. If the LED is not on, check the connection. The NxLink side modem s TR LED should not be on. 3.3 Communication Listen to the modems and verify that they are trying to establish a connection. Only the originate modem will try to dial out. If there is no attempt to connect after a few minutes, it is possible that the Initialization string may have been entered incorrectly. You will see the CD LEDs turn on once the modems have established a connection. The TD and RD LEDs will flash when the modems are transmitting data to each other. 3.4 Serial Settings If the CD LED is on and TD and RD LEDs are flashing but the NxLink web page indicates it is not connected to the device, try rebooting all devices starting with the host modem and finishing with the NxLink. Also, verify that all serial settings are correct. They should all be set as follows: Baud Rate: 19200 Data Bits: 8 Parity: None Stop Bits: 1 Flow Control: None Setup & Configuration Leased Line Modem with NxLink Page 7 IS08004 Issue 1.0
