DOWNLOAD COBOX FIRMWARE V4.4 BINARY (nts44.rom) via FTP

DOWNLOAD COBOX NTS RELEASE NOTES via FTP

There are 3 ways to load a new firmware version into a Cobox. Firmware
can be loaded through the serial port, it can be loaded over the network
via tftp or it can be sent from one Cobox to another Cobox over the network.

Lantronix has a utility called the DeviceInstaller that can upgrade the firmware over the network.
to download the latest version of the DeviceInstaller


Serial Procedure
================

Cobox firmware comes in a file with the extension .ROM. An example
filename is nts44.rom. The R2H.EXE application
mentioned below is available at:
ftp://ftp.lantronix.com/pub/cobox-utilities/r2h/r2h.exe

Before you can load firmware through the serial port you need to convert
the ROM code to HEX format. There is a DOS application, R2H.EXE that can
be used to convert the ROM file to HEX. Put R2H.EXE and the *.ROM file
into the same directory on a PC then open a DOS Window to that directory
and type

C:\ R2H nts44

to create a nts44.HEX file that you can load in via the serial port.

Connect a PC running a terminal emulator (HyperTerminal for instance)
to the serial port of the Cobox and enter Monitor Mode by typing xx1
in the terminal session while the Cobox is powering up.

Downloading is done in Monitor mode. Once in Monitor mode, type "DL".
This puts the Cobox into serial Download mode. If you're using
HyperTerminal choose "Send Text File" from the Transfer menu and
choose the *.HEX file that was created with R2H. It will take up to
several minutes for the file to be sent to the Cobox.

When the end record is received, the CoBox checks the integrity of the
firmware image and then starts programming the new firmware in the Flash
prom. While this is occurring it is absolutely necessary not to switch off
the power to the Cobox! A loss of power while reprogramming the program
code will result in a corrupt program image and a nonfunctional CoBox.

After compete reprogramming, the CoBox restarts.

Network tftp Procedure
======================

To load firmware over the network you'll need a tftp application that can
"put" a file onto the Cobox in Binary mode. Use the Cobox's IP address
for the Host Name, the filename 3Q for the Remote File Name and the name of
the *.ROM file as the Local file name, then do a tftp "put" to the Cobox.
DO NOT use the HEX version of the file when loading via tftp. Be very
careful to set the tftp application to do a Binary transfer when upgrading
over the network.

Cobox-to-Cobox Procedure
========================

To distribute the firmware of the one CoBox to others, the "SF" command is
used. After entering Monitor mode on the CoBox (see above), simply send the
firmware with the "SF" command to the other devices. For instance, to send
the firmware to another Cobox at IP address 192.168.11.200 you'd type

SF 192.168.11.200

in Monitor Mode.
