Installing a Flash-ROM Upgrade With ftp

You can upgrade the firmware on the 1765 LAN card by installing a flash-ROM upgrade. Unlike other read-only memory, flash-ROM is rewritable. This section describes how to prepare for and install a flash-ROM upgrade using ftp.

Preparing to Install

Before you install a flash-ROM upgrade, you need the following

You need a copy of ftp, the file transfer protocol software. Ftp is included with Windows for Workgroups, Windows 95, and Windows NT.

You need to know the LAN card’s IP address, which is printed on the configuration page. See “Print a Configuration Page” on page 2-13.

You can not install a flash-ROM upgrade across LocalTalk. Remove any LocalTalk connections before performing a flash-ROM upgrade.

WARNING! During the flash-ROM upgrade LAN card settings restore to factory default values. Any changes you have made will be lost. Use NEC 1765 software to reconfigure the Silentwriter. Be sure to print a configuration page before installing the flash-ROM upgrade so you will know what values have been changed. To upgrade without restoring parameters to factory defaults, use FWTOOL to perform firmware upgrades. See “Installing a Flash-ROM Upgrade With FWTOOL” on page B-5.

Installing the Upgrade in Windows 95

1.Disconnect the LocalTalk connection.

2.Turn the printer off, then on again.

3.Insert the diskette containing the flash-ROM upgrade in the drive. (This example will use drive a:)

4.Click the Start menu. From the Programs submenu select MS-DOS.

5.If the printer is on a different segment than the host, make sure the printer has an entry in the routing table. Use the route add command as follows route add <printer IP> <host IP>

Some operating systems require a 0 after <host IP>. Check with your system administrator.

6.Type ftp at the DOS prompt to run ftp.

7.At the ftp prompt type open <IP address>

where <IP address> is the IP address of the Silentwriter.

8.Ftp will prompt you for a user login. Press enter to accept the default value (none).

9.At the ftp prompt type binary

to set the data transmission mode to binary.

10.At the ftp prompt type put a:\<filename>

where <filename> is the name of the file containing the new firmware.

11.When the transfer is complete type quit

to leave ftp.

12.Type exit at the DOS prompt to return to Windows 95.

13.Print out a new configuration page by pushing the configuration button to confirm that the firmware upgrade was successful. The firmware release number is shown at the top of the configuration page.

14.Use NEC 1765 software to restore LAN card settings.
