This document assumes that the firmware revision has already been downloaded and expanded on the local hard drive. For a list of which firmware extensions go with which adapter, refer to the list at the end of this document. 
Flash memory is a type of ROM (read-only memory) that can be electronically erased and reprogrammed. The flash memory in the network adapter contains the firmware that operates it. This firmware communicates with the network, the printer, and the network utility.  When the firmware is updated, the flash memory on the network adapter is reprogrammed.  This procedure overwrites old firmware and replaces it with the upgraded version.  Although many adapters can accept each firmware file, there are some intermediate levels that must be reached before the adapter can accept the current level, as explained below. 

• The MarkNet S adapter must be flashed to 1.9.14 before it can accept any higher level of firmware. 


• The MarkNet Pro adapters must also be flashed to 2.9.14 before it can be set to the current level. 


• When a PJL file is flashed, the intermediate level is not necessary.


• The MarkNet XL must be flashed to 15.84 before it can be flashed to 79.* levels. 

Warning! While the code is being updated, be careful not to turn the adapter (or printer) off!
After the reprogramming, all of the network adapter's settings should be saved; however, this is not always the case.  Be sure to print a network settings page before starting the procedure in order to compare it with network settings after the firmware update.

From most Windows operating systems as well as OS/2,  MarkVision Classic and MarkVision Professional can be used to update the print server firmware. Firmware can also be sent using a TFTP session from Windows NT, 2000 and XP. For the MarkNet S series, N series, Pro series, and X series adapters, the internal web interface is another option for updating firmware.  Some adapters also accept PJL files which can be sent via FTP and over a parallel port.

• This document outlines MarkVision update procedures.


• This document provides information on the TFTP procedures.  


• This document provides information on the web interface update procedure.


• This document provides information on updating with a parallel connection.

For adapters that support PJL files, an FTP session can be used to update print server firmware. First download and expand the PJL file to a local directory on the hard drive.  This file is usually available for download from our FTP site as *pjl.exe under the firmware directory for each adapter. It is useful to start the FTP session from within the directory where the PJL file has been saved.  For example, if you were upgrading a MarkNet Pro adapter to 1.10.17 code, and the 1_10_17.pjl flash file was in the C:\inaflash directory, you would perform the following steps from a command prompt:

1. From the C:\inaflash directory, type ftp <ip address>  (replacing the words in anged brackets with the IP address of the adapter). 


2. Press ENTER.  A Connected status message should appear, prompting for a login ID.


3. Press ENTER to log in as an anonymous user.


4. Type bin to set up a binary transfer.


5. Type put   where is the PJL file from the Lexmark site. Press ENTER.


6. When the transfer is complete, type bye  to exit the FTP session.
   
   Important! These commands should be implemented quickly as the FTP session may time out.  A 'connection closed by remote host' error indicates that the session has timed out and must be initiated again.
