Custom Protocols
Custom protocols can be written and downloaded via a PC or over the air as systems require
change, thereby minimising disruption.
Should a special protocol or interface be required please contact the sales office.
1.18
NETWORK
MANAGEMENT
SOFTWARE
Network management software provides the user with direct access to the radio modems, for
diagnostics, programming & re-programming, safe downloading of new firmware and the
retrieval of data. All products on the I2C bus can be accessed in the same way.
1.19
SQUELCH TAIL ELIMINATION
For old or non tolerant protocols, where the presence of a mute (Squelch) tail may cause a
problem at the end of a message, a simple packetising option can be enabled.
1.20
FORWARD ERROR CORRECTION (FEC)
Forward error correction is not implemented as standard in the modem because of the loss of
throughput in good signal situations, however FEC can be offered as a custom option if
required. Note that since the internal modem offers many data speeds data integrity can be
improved simply by running a lower speed.
1.21
AUTOMATIC
FREQUENCY
CONTROL
The network management software, enables the outstation’s receiver and transmitter to be
frequency locked onto the base station s frequency and automatically re-aligned, thereby
minimising the effects of long term drift (ageing).
1.22
TX
TIME-OUT-TIMER:
The transmitter within the ART has a time-out-timer which allows the maximum continuous
transmission time to be set in order to prevent channel blocking due to a to fault. The timer
operates in all modes and can be programmed in one second steps between 0 and 255
seconds. If programmed and the time is exceeded, transmission will cease until the action
that normally causes transmission is removed and then re-applied.
1.23
DUAL CONTROLLER FOR A FULLY DUPLICATED
OUTSTATION:
For Base Station applications the BRT Series is available, the ART products can also work in
a fully duplicated mode for critical outstation applications with the aid of an ART790 DIN
baychanger module.
1.24
PROGRAMMING, SERVICE INSTALLATION & MANAGEMENT
SOFTWARE
Dedicated PC software packages have been written that provide unrivalled versatility
combined with ease of use.
1.24.1
Programming
software:
Programming software in DOS and Windows 95/98 is available for the ART Series.
1.24.2
Installation
Software:
Provides engineers with relevant software tools to align antennas, check path links in both
directions, remotely adjust the RF power at each end and log the RSSI levels.
