Values
This feature allows a Remote unit to synchronize with a specified
‘upstream’ unit (either Master or Repeater). The options are as
follows:
65535:
With this value as its Roaming Address, a Remote will
synchronize with an upstream unit which has the same Network
Name as the Remote. Should that upstream unit fail, this Remote
will attempt to synchronize with another ’upstream’ unit within the
same network (i.e. same Network Name). This ability is particularly
well-suited to mobile applications.
1-254:
In most static (fixed) networks, where there are no
Repeaters, the default value of 1 is maintained: All Slaves
synchronize to the Master (whose unit address is 1).
In networks where Repeaters are present, the value of a Remote’s
Roaming Address typically corresponds to the particular upstream
modem with which a particular Remote is intended to communicate,
e.g. Slave with Unit Address 3 may have a Roaming Address of 2,
where the modem with Unit Address 2 is a Repeater between the
Slave and the Master; the Repeater will have a Roaming Address
of 1 as it is to synchronize to the Master.
The Roaming Address dictates to which EtherWave-WMR (by Unit
Address (UA)) a Remote (or Repeater) will ’look’ or ’attach to’ for its
upstream signal path.
See the description of Network Profile earlier in this section for
more information about roaming-type options. The Network Profile
allows for roaming between networks whereas the Roaming
Address provides for roaming within a network.
When bench testing 3
EtherW av e-WMR for a
Master-Repeater-Rem ote
link, be sure to set the
Remote’s Roaming Address
to the Unit Address (UA) of
the Repeater, and the
Repeater’s Roaming Address
to the UA (1) of the Master.
This will ensure that data is
routed from the Remote
through the Repeater to the
Master; otherwise, if the
Remote’s Roaming Address
is left at the default value of 1,
the Remote will communicate
directly with the Master,
bypassing the Repeater
altogether.
