This manual describes how to install both the Savi RF Relay model
100 (RFR-100)and the Savi RF Relay model 200 (RFR-200). Both
models provide wireless links among readers or between readers
and a host computer. The RFR-100 connects to RS-485 networks,
while the RFR-200 connects to LonWorks® networks.

In situations where wired connection is impractical between a
host computer and a network of SaviReaders (or between two
sub-networks of SaviReaders), two Savi RF Relays can create a
wireless connection. This connection allows one host computer
to control readers that monitor a much larger physical area than
is possible using only wired connections.
The Savi RF Relay is available in two models, both of which are
described in this manual:
•The RFR-100 model provides a long-distance wireless link
in an RS-485 network, using an RF modem.
•The RFR-200 model provides a long-distance wireless link
in a LonWorks network, using an RF modem.
Both models of the Savi RF Relay have four basic components:
•The RF Relay itself, which includes a wireless transceiver
and network interface in a weatherproof NEMA enclosure
•An up/down converter (two models), which provides
necessary frequency conversion between the RF Relay and
the antenna
•A bandpass filter that attaches to the end of the antenna
(up/down converter model UDC2.4B-0C only)
•An omnidirectional 2.4 GHz antenna
Figure 1-1 shows a Savi RF Relay with its antenna and up/down
converter mounted on the same mast.
