Updating Using WinSCP
Several of the version updates for ZyWAN are fairly large. For this reason, it may not be recommended to
use the Web interface described above because of the cost or length of time it requires to load files over the
cellular network. The following method describes how to load the ZyWAN update files locally over Ethernet
or WiFi and to install them manually.
See the section SFTP/SCP Client (WinSCP) on page 27 for information on installing the WinSCP file transfer
program. This program provides a free and secure means of loading the required files, although other
programs may be used which support the SFTP or SCP protocols.
Determine the current software revision by viewing the Status tab of the ZyWAN Web configuration page.
The following screen capture shows an example indicating a ZyWAN at software revision level 1.4.
The required files can be obtained upon request from Eurotech, or they may be downloaded from
http://files.arcom.com/Zywan/updates/ . From this Web site, choose the update file “Zywan-
1. x to1. y update.tar” as mentioned next, depending on what version from which the ZyWAN is starting.
Starting with versions 1.2 through 1.4
If the ZyWAN is currently at version 1.2, the following file is needed:
Zywan-1.2to1.5update.tar
If the ZyWAN is currently at version 1.4, the following file is needed:
Zywan-1.4to1.5update.tar
