1.3 Configuration
Operating characteristics of Integra-TR are con­figured by means of Integra-TR’s
Software
(RSS) available from your sales repre-
sentative. Also available is Integra-T’s
Diagnostic Software
(RDS) which permits both
local and remote diagnostics.
Service Software (RRSS
) to allow remote pro­gramming is a future expansion. The RSS, RDS and RRSS (future option) programs are MSDOS based and will run on any 486 or higher PC (2 Megabytes memory required).

1.5 Product Warranty
Warranty information may be obtained by con­tacting your sales representative.
1.6 Replacement Parts
This product is normally not field-serviceable, except by the replacement of complete units. Specialized equipment and training is required to repair logic boards and radio modules.
1.7 Physical Description
Integra-TR consists of a logic PCB (which in­cludes the modem circuitry) and a separate radio module. The two boards plug directly together and slide into the rails of an extruded aluminum case. DTE connection is made 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 enclosure where dust and/or a corrosive atmosphere are anticipated. There are no external switches or adjustments; operating parameters are set using the RSS.
1.8 Diagnostics
Integra-TR has sophisticated built-in diagnostics that may be transmitted automatically without interfering with normal network operation. In addition, commands to generate test transmis­sions, etc., may be issued either locally or re­motely.
Diagnostic information takes one of two forms:
120 40101-103
2
Integra T Technical Manual
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.
Diagnostics are processed using the Integra-TR’ RDS.
1.8.1 Remote Commands
The upcoming Integra RRSS will allow config­uring most functions and adjustments remotely via the radio network. Sending remote commands and receiving re­sponses is done with the host application off­line.
1.10.2 Basic Connections
The connections required (except power) are shown below in Figure 1. While an RTU or PLC is shown in the diagram, master stations often use a PC running an appli­cation designed to communicate with remote RTUs or PLCs. The Setup PC is used for both configuration and local and remote diagnostics. It may be left con­nected at all times if desired, but is not required for normal operation once the unit has been con­figured.
Antenna
1.9 Firmware Upgrades
Integra-TR’s firmware resides in flash EPROM and is designed to allow field upgrades. Upgrades are done using a PC connected to In­tegra-TR and do not require that the unit be opened.
1.10 Network Application
Integra-TR is suited to a variety of network ap­plications. Its primary design goal was to satisfy the needs of SCADA systems using RTUs or PLCs in either point to point or point–multipoint service.
This section gives an overview of some common configurations. Selection of “master” or “re­mote” as well as data delivery conditions is done using the Integra RSS.
1.10.1 RF Path and Communications
Range
Integra-TR is designed for use over distances up to 30 miles (50 km) depending on terrain and antenna system. To assure reliable commun­ications, the RF (radio frequency) path between stations should be studied by a competent pro­fessional, who will then determine what anten­nas are required, and whether or not a repeater is needed.

1.10.3 Common Characteristics
The networks described below share a number of common characteristics.
1. The network speed (4800 or 9600 b/s) must be the same for all stations in a network.
2. Unless otherwise noted, the default setting of station type is “master” and data delivery is “all”.
3. Transmission of online diagnostics may be enabled or disabled at any station or stations without affecting their ability to commun­icate with other stations.
1.10.4 Point to Point System
A simple point to point connection is shown below:

DTE
Figure 2 - Point to Point System
In such a system, the user’s equipment (DTE)
Integra
DTE
may be set up in either a peer-to-peer or a mas­ter slave configuration. The Integra-T’s may be left in their default configuration, which is:
1. Both units set as “master”.
2. Both units set to deliver “all” data transmis­sions.
Two other configurations that would work equally well are:
1. One unit set to “master”, the other to “re­mote”, delivery set to either “all” or “selec­tive” data transmissions.
2. Both units set to “remote”, data delivery set to “all”.
If a simplex radio network is used (i.e. a single frequency for all stations) we recommend that the master Integra-TR be set to “master”, the remotes to “remote” and all units to “selective” data delivery. This will prevent remote stations from hearing each other’s responses. Use this setting also if a full duplex repeater is used.
1.10.6 Extending a Landline (Tail Circuit)
Integra-TR may be used to extend a landline circuit (giving access to difficult locations, etc.). This type of connection is called a “tail circuit” and is shown in Figure 4 below. The tail circuit assembly may be used in any of the network types described in the preceding sections.

Figure 3 - Point–Multipoint System
If a half-duplex radio network is used (i.e. two frequencies with the master station transmitting and receiving on the reverse pair from the re­motes) the Integra-TR’s may be left in their de­fault configuration (station type “master” and data delivery “all”). The master station can be either full duplex or half-duplex.
