Software disks are also available from MDS that include a loader pro-

gram for downloading the code on the disk into the radio. Contact MDS

Technical Support for details. Finally, if you have an InSite CD from

MDS, it also will have radio code on it, but it may not be the latest ver-

sion.

9.2 Preparing for Download

MDS software upgrades are distributed as ASCII files with a “.S28”

extension. Browse to find the desired “.S28” software file for your radio.

After finding your selection use the Right mouse button to select a path

on your computer to download the software to. (If this isn't done your

browser may display the software code instead of downloading it.)

After the “.S28” file has been saved to your computer, you must use

MDS Radio Configuration Software to load this software into your

radios. This software may also be downloaded, if needed.

NOTE: By default, the MDS x790 will download to the standby

module of a redundant radio without interrupting its normal

operation. Non-redundant radios will experience an interrup-

tion in service during the code download.

9.3 Downloading New Code—Procedure

1. Start the Radio Conﬁguration Program and let it open diagnostics

and read the radio information.

2. From the System menu select Radio Software Upgrade and follow

the prompts to download the code. Do not press the Cancel button

once the download starts or it will leave the radio without any code.

When the download is complete the other radio module (if present)

will need to be programmed.

To program the second radio, go to the System Menu and enter the Ter-

minal Mode. At the prompt > type switch to change the active module,

exit the Terminal Mode and repeat the download procedure.
