Banner Field and “i” button
This field displays a string made up of the serial
number of the connected unit followed by the
firmwares used and their version number.
Format is:
[serial number]:firmware 1 name, its version #,
firmware 2 name, its version #.
The serial number portion uniquely identifies
the unit. It is a variable length, maximum eight-
character alphabetic string assigned at the time
of manufacture. It is identical to the serial num-
ber printed on the label of the unit. This number
cannot be changed and is used as part of the on-
air protocol.
Gemini/PD's firmwares resides in flash EPROM
and are designed to allow field upgrades.
When contacting your supplier, give the full
banner string and the version of the RIS used.
You will find the version number in the “About”
window. To open it, click the lower left square
button (with a lowercase letter “i” in it).
This field is blank prior to doing "Get", "Get As"

The Dataradio supplied password algorithm is
designed to thwart the casual observer only. It
provides a limited form of data privacy. There-
fore, if your security requirements are high,
Dataradio urges you to use external encryption
technology (such as Data Encryption Standard
(DES)) in the Host and Mobiles computers.
