Page 106: Installation And Configuration Troubleshooting
Installation and Configuration Troubleshooting Cannot use the first computer installed with the Single-Host NPort Server Lite Manager to access NPort Server Lite. For security reasons, and to simplify operations, the Single-Host Mode allows only one host to connect to NPort Server Lite at a time. Thus, if while using the single-host type of installation you discover that the server has already been configured with password protection, it is advised that you check to see if two or more NT/95/98 hosts are sharing the same NPort Server Lite configured for Single-Host Mode. - Page 107 After installing NPort Server Lite, the NPort Server Lite Manager program indicates “'Un-authorized” status for some of the ports. This means that NPort Server Lite’s Access Control list does not contain your computer’s correct IP address. This can happen in one of two ways: 1.
- Page 108 2. If the route is okay, try running ping [server-IP-address] from your NT/95/98 host, where [server-IP-address] is the server’s IP address. If the server cannot be pinged, you will need to ask someone at the remote site to check and see if the power is on, and make sure that the connection is okay. And then double click on the server icon that has the question mark (?) on top.

Page 109: Programming Problems
Programming Problems Win32 COMM API functions return fail, or the PComm Pro library functions return a Fail code - SIO_WIN32FAIL The fail code for the COMM API functions implies something different than the fail code received from the standard COM driver. For example, you get the fail code when the network connected to the server is unreachable, or the server is offline. -

Telnet Console This appendix contains instructions and illustrations that explain how to use Telnet Console Interface. The following discussion and examples were generated by running Telnet from a Windows NT/95/98 host. Starting Telnet From the Windows NT/2000/95/98 desktop click on Start and then choose Run. As shown below, type telnet [NPort Server Lite IP address] in the Open text box, where [NPort Server Lite IP address] is the NPort Server... - Page 112 You should see a window requesting the Console terminal type you would like to use. Type 1 for ansi/vt100 and then press Enter. This activates the Telnet Console Interface utility program. In what follows we refer to the screen shown below as the Telnet Console Interface MAIN MENU. Navigating the Telnet Console After activating the Telnet Console, you will need to use the keyboard keys to maneuver about the vt100 screen.
- Page 113 The Esc key is used to maneuver backwards. For example, if you have made modifications to the settings listed under the serverConfig menu, press the Esc key to return to the MAIN MENU. When you first activate the Telnet Console Utility’s MAIN MENU, you may find that the arrow keys on your keyboard initially have no effect on the cursor.
- Page 114 Attributes that can be edited are enclosed in square brackets, and those that can’t be edited are not enclosed in brackets. Furthermore, there are two types of configurable attributes, those with a large number of possible settings, and those with only two or three possible settings.
- Page 115 Telnet Console Press Enter to activate a pop up window displaying the two DHCP options (shown below). Use the up/down arrow keys to highlight the desired setting, and then press Enter. The new setting, enclosed in square brackets will appear to the right of Operating Mode. If you find that you chose the wrong setting, simply press Enter again to reactivate the pop-up window, and choose the correct setting.
- Page 116 Serialport Options Starting from the Telnet Console Interface MAIN MENU, use the arrow keys to position the cursor over the Serialport menu, and then press Enter to display the configurable options RS-422/485 Interface, RS-485 Comm. Mode, and Tx FIFO. The options are as follows: RS-422/485 Interface RS-485 Comm.
- Page 117 Telnet Console Monitor The Monitor function displays the following information: Ping Ping is a standard network testing function that checks to see if a computer with a particular IP address is logged onto the network. Highlight Ping and then press Enter to activate the function.
- Page 118 The program begins sending “packets” of data, and tests the return response. Press Esc to stop sending, and to receive a short report. In this case the ping was successful. If you try pinging an IP address for a device not connected to your network, the report will tell that “0 packets were received”.

Page 119: Lcd Panel Configuration
LCD Panel Configuration In this appendix we explain how to operate the LCD display using the four buttons on NPort Server Lite’s top panel. It’s best if your NPort Server Lite is in front of you and plugged in. (If necessary, see the section Connecting the Hardware from Chapter 2 for an explanation of how to connect the power cord.) Basic Operation If the server is working properly, the LCD panel will display a yellow color for a few... - Page 120 The buttons are manipulated in a manner similar to the way a modern cellular phone is operated. As you move through the various functions and setting options, note that the top line shows the current menu or submenu name, and the bottom line shows the submenu name or menu item which is activated by pressing the Detailed Menu Options The best way to display all of NPort Server Lite’s LCD functions is to use the tree graph...
