Integra T Technical Manual
1.8 Physical
Description
The Integra-T consists of a logic PCB (which
includes the modem circuitry) and a separate
radio module. The two boards plug directly to-
gether and slide into the rails of an extruded
aluminum case. DTE connection is via a front
panel connector. Power is applied through a
connector, which also includes analog inputs, on
the rear panel. The unit is not hermetically
sealed and should be mounted in a suitable en-
closure where dust and/or a corrosive atmos-
phere are anticipated. There are no external
switches or adjustments; operating parameters
are set using the RSS.

1.9 Diagnostics
The Integra-T has sophisticated built-in diag-
nostics which may be transmitted automatically
without interfering with normal network opera-
tion. In addition, commands to generate test
transmissions, etc., may be issued either locally
or remotely.

Diagnostic information takes one of two forms:
Online diagnostics. Information is auto-
matically sent by each unit at the beginning
of every data transmission.

Offline diagnostics. Information is sent by a
specific unit in response to an inquiry made
locally or from another station.

Commands
The upcoming Integra RRSS will allow config-
uring most functions and adjustments remotely
via the radio network.

1.11 Network Application
The Integra-T is suited to a variety of network
applications. Its primary design goal was to sat-
isfy the needs of SCADA systems using RTUs
or PLCs in either point to point or point–multi-
point service.

1.11.1 RF Path and Communications
Range
The Integra-T is designed for use over distances
up to 30 miles (50 km) depending on terrain and
antenna system. To assure reliable commun-
ications, the RF (radio frequency) path between
stations should be studied by a competent pro-
fessional, who will then determine what anten-
nas are required, and whether or not a repeater is
needed.
