7.5 Upgrading the Radio’s Software
From time to time, new product features or software maintenance files
may become available from MDS. This section describes the steps nec-
essary to install new software into the transceiver using a PC connected
to the radio’s
DIAG. port.
Upgrade software can be obtained in a number of ways. The MDS Web
site at www.microwavedata.com contains an FTP area with software
files for several radio models. You can browse the listings to see if there
are files pertaining to your particular model. There is no charge for this
service.
In addition, you can also contact MDS to request radio software. Soft-
ware files may be sent to you via e-mail, or on a 3.5” diskette. There may
be a nominal charge for the software depending on the nature of the
upgrade.
