1.5 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.
Contact Technical Service for information before returning equipment. A Technical Service
representative may suggest a solution eliminating the need to return equipment.
1.6 FACTORY REPAIR
Dataradio products are designed for long life and failure-free operation. If a problem arises, factory
service is available. Contact the Technical Service Department before returning equipment. A service
representative may suggest a solution eliminating the need to return equipment.
A Return Material Authorization (RMA) is required when returning equipment to Dataradio for repair.
Contact the Technical Service Department at 800-992-7774, extension 6290 to request an RMA number. Be
prepared to give the equipment model and serial number, your account number (if known), and billing and
shipping addresses.
Include the RMA number, a complete description of the problem, and the name and phone number of a
contact person with the returned units. This information is important. The technician may have questions that need
to be answered to identify the problem and repair the equipment. The RMA number helps locate your equipment
in the repair lab if there is a need to contact Dataradio concerning the equipment. Units sent in for repair will be
returned to the customer re-tuned to the current Dataradio Test and Tune Procedure and will conform to all
specifications noted in this section
Customers are responsible for shipping charges (to Dataradio) for returned units in warranty. Units in
warranty are repaired free of charge unless there is evidence of abuse or damage beyond the terms of the warranty.
Dataradio covers return shipping costs for equipment repaired while under warranty.
Units out of warranty are subject to repair service charges. Customers are responsible for shipping charges
(to and from Dataradio) on units out of warranty. Return shipping instructions are the responsibility of the
customer.
1.7 PHYSICAL DESCRIPTION
Integra-H consists of a logic PCB (which includes modem circuitry) and a radio module. Each logic PCB
and radio module are matched together and characterized in the factory to optimize performance as an intelligent
unit. The two boards then slide into the rails of an extruded aluminum case.
The Integra-H transceiver “hops” from channel to channel several times per second using a “hop” pattern
applied to the master and remotes in a network. A distinct hopping pattern is provided for each of the available
network addresses. This distinct pattern minimizes the chance of interference with other spread spectrum
networks. In the United States (and certain other countries), no license is necessary to install and operate this type
of spread spectrum system.
DTE connection is made via a front panel connector. Power is applied through a rear panel 4-pin
connector which includes two programmable analog connections usable as inputs or specialized outputs.

Part No. 001-4090-101/102
The unit is not hermetically sealed and should be mounted in a suitable enclosure when dust and/or a
corrosive atmosphere are anticipated. Physically, there are no external switches or adjustments. All operating
parameters are set using the INTRSS software program.
1.8 DIAGNOSTICS
Integra-H 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:
Online diagnostics Information is automatically sent by each unit at the beginning of every data
transmission. Online diagnostics are available via the setup port or INTDIAG software.
Offline diagnostics Information is sent by a specific unit in response to an inquiry made locally or from
another station. Off
1.9 FIRMWARE UPGRADES
The Integra-H firmware resides in flash EPROM and is designed to allow field upgrades.
Upgrades are done using a PC connected to the Integra-H but do not require opening the unit. Upgrades
require interaction with DRL’s Technical Service.
1.10 INSTALLATION
1.10.1 PROFESSIONAL INSTALLATION REQUIRED
The Integra-H complies with Part 15 of the FCC rules and must be professionally installed. Operation
must conform to the following conditions
lThis device may not cause interference
lThis device must accept any interference including interference that may cause undesired operation of
the device
The installer of this equipment must ensure the antenna is located or pointed such that it does not emit
RF field in excess of Health Canada limits for the general population; consult Safety Code 6 (available from
Health Canada).
1.10.2 ANTENNA CONNECTION
This equipment has been tested and approved with antennae having a maximum gain of 10 dB. Antennae
with a higher gain are strictly prohibited (regulations of Industry Canada). The required antenna impedance is 50
ohms. To reduce potential radio interference, the antenna type and its gain should be chosen to ensure the
equivalent isotropically radiated power (EIRP) is not more than required for successful communication.

Part No. 001-4090-101/102
FCC/IC Rule: The output power is not to exceed 1.0 watt and the EIRP not to exceed 6 dBW if the hopset
uses 50 or more frequencies. A sample calculation is provided below.
Sample Calculation: Yagi Antenna: 10 dB Exceeds 6 dBi gain by 4 dB
Cable Loss: 1 dB
Integra-H output must be reduced by 4 dB (plus 1 dB to account for cable loss)
30 dBm - 4 dB + 1 dB (cable loss) = 27 dBm at antenna port of Integra-H
after 1 dB loss through cable: 27 dBm - 1 dB = 26 dBm input to antenna
Result: reduction of 4 dB

1.10.3 ACCEPTABLE ANTENNAE
The antennae listed in Table 1-2 were tested and typed for maximum gain. These antennae are FCC
approved for use with the Integra-H. Table 1-2 Acceptable Antennae
1.10.4 SAFETY NOTICE
The Integra-H uses low power radio frequency transmitters. The concentrated
energy from an antenna may pose a health hazard. People should not be in front of
the antenna when the transmitter is operating.

1.11 NETWORK APPLICATION
Integra-H is suited to a variety of network applications. Its primary design goal satisfies the needs of
SCADA systems using RTUs, PLCs, or other similar equipment in either point-to-point or point-to-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 INTRSS.
1.11.1 RF PATH AND COMMUNICATIONS RANGE
Integra-H is designed for use over distances dependent on terrain and antenna system. To assure reliable
communications, the RF (radio frequency) path between stations should be studied by a competent professional
who can determine what antennae are required and whether or not a repeater is needed.
1.11.2 BASIC CONNECTIONS
The connections required are shown in Figure 1-2.
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 but is not required for normal operation once the unit has been configured.

1.11.3 COMMON CHARACTERISTICS
The networks described in this section share common characteristics:
1.The network speed (9600, 19200, 21400, and 25600 b/s) must be the same for all stations in a network.
2.Transmission of online diagnostics may be enabled or disabled at any station or stations without
affecting their ability to communicate with other stations.
1.11.4 POINT-TO-POINT SYSTEM
A simple point-to-point connection is shown in Figure 1-3.
Figure 1-3 Point-to-Point System
In this system, the user's equipment (DTE) is set up in a master-remote configuration.
1.11.5 POINT-MULTIPOINT SYSTEM
Basic point-multipoint systems are shown in Figure 1-4:
Figure 1-4 Point-Multipoint System
Using the Integra-H programming software, one Integra-H must be set to “master”. The remaining units in
the network must be set to “remote”. All units are set to “selective” data delivery to prevent remote stations from
hearing each other's responses.

1.11.6 EXTENDING A LANDLINE (TAIL CIRCUIT)
Integra-H 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 1-5. The tail circuit assembly may be used in any of the
network types described in the preceding sections.
Figure 1-5 Landline (Tail Circuit)
Note: The phone-line modems should be full duplex units.
Figure 1-6 DCE Crossover Cable for RTS-CTS mode
Some point-to-point FDX landline modems or line drivers may require the use of DOX mode and an
alternate pinout for DTR, DCD, CTS and RTS as shown in Figure 1-8.
