1.1 PRODUCTS COVERED
This Manual covers the R.F. Technologies ART Series Radio Modems and repeaters.
Information is provided to program, install, and operate the products in various
configurations.
With the built-in test software, first line “Go-No Go” testing can be easily performed.
Component level servicing is not covered in this document, if the product fails its first line
testing it should be returned to a service centre.
1.2 INTRODUCTION
The ART Series are high performance, very low current consumption, dual Synthesised
Radio Modems, designed specifically for the Telemetry and Data market, where the fast
transfer of data is required over reliable wireless links.
The ART was designed as a result of research into market requirements for a product that
would work in a large majority of applications. As a result the ART will fit into almost any
system using licensed, or license exempt telemetry channels in the VHF, UHF & 900MHz
bands.
The ART product is unique in its use of a single flash microprocessor to control both the RX
& TX radio modules, external interfaces
, and function as a full duplex modem with
programmable speeds up to 9600bps.
1.3 OVERVIEW
1.3.1 RADIO FREQUENCY (RF) SECTION
The ART employs separate receiver and transmitter modules connected to a common
microprocessor and interface board. The RF modules have separate synthesisers to enable
full duplex operation and in simplex operation facilitate
s very fast turn around times.
The ART has been specially designed with very low group delay filters to provide the best
path for high speed data signals. Each RF module is a self contained unit, that plugs into the
control board and in the unlikely event that a R.F unit fails, it can be easily replaced and sent
to our service centre for repair.
No attempt should be made to repair the unit except by experienced RF personnel with
Proper RF test equipment is available.
NOTE: Adjusting any of the controls within the RF module may degrade the transceiver's
performance or put its operation outside the approved specification.
1.3.2 TRANSMITTER
The transmitter can be programmed anywhere within a pre-aligned bandwidth, which is
within a wider tuneable F band, details of the bandwidths are in the technical specifications.
Both High power (20mW – 5Watts) and low power (10mW – 1Watt) products are available.
For ease of operation, all parameters are PC programmable with channel change duplicated
on the external switches.
