Laptop/PC Serial Port Connection to NAM

To connect your laptop using the serial cable to a NAM 3.0 follow this procedure. Because of its age, it was the change point where the gui was resident in the NAM and where you needed to set the dial up properties in your laptop. Here is the newer config method for NVM 3.0 and up:

  1. Copy NVMPPP2.inf (it comes with NVM Manager Software) to your hard drive
  2. Go to the control panel and double click the 'modems' icon. If a modem has previously been installed, click on the 'add' button. If a modem has never been installed, an 'install new modem' dialog box is presented right away without being prompted to press a button for 'add', 'remove', or 'properties'
  3. On the 'install new modem' dialog box, check 'don't detect my modem' box
  4. Click the 'next' button
  5. Click on 'have disk'
  6. In the next dialog box enter the path to the file that you copied in step one
  7. Click on 'direct serial connection'
  8. Click on the 'next' button
  9. Click on the port where your direct connection is going to be on this windows PC - choose your laptops com port here)
  10. Windows takes a few seconds to install this new device driver. After it is done, click the 'finish' button. The title of the modem, 'direct serial connection' should appear in the next window
  11. Click 'OK'
  12. Go into dial up networking and make a new connection
  13. when the dialog box comes up select the direct serial connection as your modem. Give a name for this type of connection in the 'type a name for the computer you are dialing' field. An example name would be 'NAM Serial Port' and click configure
  14. Set the speed to 19200
  15. Choose the 'connection' tab and remove the check for ' wait for dial tone before dialing' and change the 'cancel the call if not connected within 60 secs' to be 0 secs. DO NOT REMOVE THE CHECK FROM THE BOX!!!!
  16. Press 'OK'. Then click on the 'next' button. It does not matter what you put in for a phone number. At this time go to dial up networking and choose the properties for this new connection that you have made. Choose 'server type'. Although the server type must be PPP, and TCP/IP must be an allowed network protocol, the other settings such as 'log on to network', 'enable software compression', 'require encrypted password' do not matter for the TCP/IP settings. Ensure that 'server assigned IP address' and 'server assigned name server addresses' are all checked. Ensure that 'use IP header compression' and 'use default gateway on remote network' are also checked
  17. Reboot, and test.
