Monitoring Network
ed Motorola and P25
Systems Some of the systems that ar
e pr
epr
ogrammed in
your scanner ar
e networked, multi-site Motor
ola
systems, such as Smartzone, OmniLink, and networked P25 systems. These systems ar
e
designed to cover very lar
ge ar
eas by using
multiple networked transmitter sites, each with its own set of fr
equencies.
Your Advanced Digital Scanner includes a Multi- site featur
e that can enhance the operation of
the scanner when monitoring Multi-site systems. Multi-site can be enabled by editing the trunking system (TSYS) parameters for the system. Multi- site can be set to Of
f, Stat (Stationary), or Roam.
By default, Multi-site is set to Of
f.
To
activate Multi-site mode on a pr
epr
ogrammed
Motor
ola or P25 networked system:
1.
Pr
ess
PGM (PROG),
then navigate to a
talkgr
oup on the networked multi-site system
using the
STWX
keys.
2.
Pr
ess the
EDIT
softkey
, then pr
ess the
CURR
softkey
.
3.
Scr
oll down to the TSYS item and pr
ess the
SEL
key to edit the TSYS parameters.
4.
Scr
oll to Multi-site. Use the
WX
keys to
select
Off, Stat,
or
Roam
. When set to
Off
,
the scanner will find the first usable contr
ol
channel in the contr
ol channel list and use
it until it is no longer usable. When set to Stat
, the scanner will track the system using
any contr
ol channel in the list that is usable.
When set to
Roam
, the scanner will attempt
Using the Preprog
rammed Data
to locate and use the best possible contr
ol
channel and ignor
e others, until the contr
ol
channel is no longer usable, then it will locate a new “best contr
ol channel” to use. Roam
decisions ar
e made using the Thr
eshold
Hi and Thr
eshold Lo settings. For mor
e
information on Multi-site, please see
“Multi-
Site Mode On Network
ed Systems”
in your User’
s
Guide.
5.
Pr
ess the
SAVE
softkey to save your changes
to the TSYS parameters, then pr
ess the
SAVE
softkey again to use the scanner
.
6.
You should experiment with dif
fer
ent Multi-
site modes and thr
eshold settings to find a
combination that works best for your location. Keep in mind that the thr
eshold settings
ar
e only available when Multi-site
Roam
is
selected.
7.
Multi-site functionality is not available in EDACS or L
TR trunking.

CS Systems
Some of the systems that ar
e pr
epr
ogrammed in
your scanner ar
e networked, multi-site EDACS
networks. Like Motor
ola and P25 networked
systems, these EDACS systems ar
e designed
to cover very lar
ge ar
eas by using multiple
networked transmitter sites, each with its own set of fr
equencies.
EDACS trunking is quite dif
fer
ent fr
om Motor
ola
and P25 trunking. W
ith Motor
ola and P25
trunking, the subscriber radios on the system (and your scanner) get all of the system channel fr
equency information fr
om the contr
ol channel,
which simplifies wide-ar
ea networked system
scanning. In EDACS, it is necessary to pr
