Tag name Description
upstream unit which has the same network address and static mask as the
Remote. Should that upstream unit fail, this Remote will attempt to
synchronize with another ’upstream’ unit within the same network. This
ability is particularly well-suited to mobile applications.
Roaming=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 (UA) is 1). In networks where Repeaters are present, the value of
a Remote’s roaming value corresponds to the particular upstream radio,
with which a particular Remote is intended to communicate.
( e.g. A Slave with a UA=3 may have Roaming=2, where the radio with a
UA=2 is a Repeater between the Slave and the Master; the Repeater will
have Roaming=1.)
When setting up 3 radios for a Master-Repeater-Slave link, be sure to set
the Slave’s Roaming to the UA of the Repeater, and the Repeater’s
Roaming to the UA of the Master(1). This will ensure that data is routed
from the Slave through the Repeater to the Master; otherwise, if the Slave’s
Roaming is left at the default value of 1, the Slave will communicate directly
with the Master and bypassing the Repeater altogether.

1-254 Specific (fixed) UA of Master or Repeater with which to associate
Voltage Supply voltage as measured on motherboard.
VSWR Voltage Standing Wave Ratio. Ideally 1:1 (or 1.00), this value gives an
indication of how much power is being reflected back to the radio from the
antenna relative to how much is being transmitted.
Operation Mode The operating mode defines the role of a radio. An IHFS radio may be
configured for any role required within a radio network. This is convenient
for reasons of familiarity with any/all units, as well as for hardware sparing
purposes.
The default operating mode is dependent on which factory default option is
selected.
MASTER: Only one per network. In all network types data either originates
at, is destined to, or ‘passes through’ the Master.
REPEATER: May act simply as a ‘Repeater’ to store and forward data
to/from an upstream unit to/from a downstream unit (e.g. when there is a
long distance between the latter units), or, may act as a Repeater/Slave in
which case the above function is performed AND the unit may also
exchange data as a Slave within the network.
SLAVE: Interfaces with remote devices and communicates with Master
either directly or via Repeater(s). Communications between 2 or more
Slaves is possible - through the Master.
A ‘Remote’ (non-Master) modem is either a Repeater or a Slave. If a
Repeater is not being used as a Repeater/Slave (i.e. there is no device
attached to its local data port), leave its handshaking OFF (&K0) and set
the serial baud rate (S102) to 115200bps.
