1.7 PHYSICAL DESCRIPTION
Integra-TR 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.
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 outputs.
The unit is not hermetically sealed and should be mounted in a suitable enclosure where dust and/or a
corrosive atmosphere are anticipated. Physically, there are no external switches or adjustments. All operating
parameters are set using the Field Software Program.
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:
Online Diagnostics Information is automatically 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.

Part No. 001-4008-101/102
1.9 FIRMWARE UPGRADES
The Integra-TR firmware resides in flash EPROM and is designed to allow field upgrades.
Upgrades are done using a PC connected to the Integra-TR but do not require opening the unit. Upgrades
require intervention with DRL’s Technical Service.
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-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 the Integra-TR Field Programming Software.
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 can determine what antennas are required and whether or not a
repeater is needed.
1.10.2 BASIC CONNECTIONS
The connections required are shown in Figure 1-3.
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.

1.10.3 COMMON CHARACTERISTICS
The networks described in this section share common characteristics:
1. The network speed (2400, 4800, 9600 and 19,200 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.
1.10.4 POINT-TO-POINT SYSTEM
A simple point-to-point connection is shown in Figure 1-4.
Figure 1-4 Point-to-Point System
In this system, the user's equipment (DTE) may be set up in either a peer-to-peer or a Master-Remote
configuration.
1.10.5 POINT-MULTIPOINT SYSTEM
Basic point-multipoint systems are shown in Figure 1-5:
Figure 1-5 Point-Multipoint System (Simplex or half-duplex)
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 master station can be either full duplex or half-duplex.

1-14
Part No. 001-4008-101/102
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.
For full duplex configuration, set the receiving unit Rx/Tx
Mode to Rx Only (using the Field Programming Software).
Set the transmitting unit mode to Tx Only

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 1-9. The tail circuit assembly may be used in any
of the network types described in the preceding sections.

2.3 REAR PANEL
Figure 2-4 Integra-TR rear panel
The various elements are described in the following sections.
2.3.1 Heat Sink
The rear panel heat sink is essential for proper operation of the Integra-TR transmitter. The unit must be
mounted in a location that permits free air circulation past the heat sink. Cooling will be best if the fins are
vertical.
2.3.2 Power
The Integra-TR power requires a regulated power source of 13.3 VDC nominal (10 - 16 VDC max.)
negative ground with a 3.0 A rating. An internal surface-mount 3A fuse (not field-replaceable) and a
crowbar diode protect the main RF power components from reverse polarity. Application of more than 16
VDC will damage the unit and is not covered by the warranty.
WARNING: Do not exceed 16Vdc.

2.4 INTEGRA-TR FIELD PROGRAMMING SOFTWARE
2.4.1 Introduction
The Integra-TR Field Programming Software is the programming and diagnostics software for the Dataradio
Integra-TR wireless modem. The Field Programming Software allows the user to edit and program user
programmable settings, interactively tune modem and RF parameters, and monitor diagnostic data from the
Integra-TR. See Figure 2-6 for the Integra-TR Field Programming Software startup screen.
This manual assumes the Field Programming Software has been installed on the user’s PC with at least one
operational serial COM Port available.
2.4.2 COM Port Settings
Integra-TR programming is done through the PC’s Primary COM Port. Primary and secondary COM ports
are configured with the Field Programming Software. The programming cable (included in the
Programming Kit - DRL part number 250-4008-001) is connected from the Setup Port on the Integra-TR to
the PC’s COM port configured as the Primary Port. The Port Settings screen of the Field Programming
Software is accessed via the Utilities pull-down menu (see Figure 2-7). The Port Settings screens are used to
configure the PC’s serial COM Ports. COM Port parameters are defined in 2.4.2.1. COM Port assignments
are displayed in the bottom status bar of the Integra-TR Field Programming Software screen.
2.4.2.1 COM Port Parameters
COM Port
Selects COM Port number (COM 1-4) for Primary and Secondary COM Ports (see Figure 2-7).
2-6
Part No. 001-4008-101/102
Figure 2-7 Port Settings Screens
Baud Rate
Selects the communication speed for Primary and Secondary COM Ports.
Data Bits
Selects the number of data bits (4-8) transmitted or received for the Primary and Secondary COM Ports.
Parity
Selects transmission or reception of any Parity Bits for the Primary and Secondary COM Ports.
Stop Bits
Selects number of Stop Bits (1 or 2) transmitted or received for the Primary and Secondary COM Ports.
DTR Enable
Used to assert DTR (Data Terminal Ready) line of the RS232 Port when the port is open for the Primary and
Secondary COM Ports.
Swap COM Ports
Selecting the Swap Com Ports button moves the Secondary COM Port settings to the Primary COM Port
(and moves the Primary COM Port to the Secondary settings). Since Integra-TR programming is done
through the Primary COM Port, this is useful when two units are connected to the Primary and Secondary
COM Ports. A Swap COM Ports allows the second unit to be programmed without switching programming
cables.

2.4.3.1 Modem Operating Parameters
The Setup Modem/Radio Parameters allows the user to view and edit Integra-TR’s programmable
parameters. Programming parameters can be stored in a data file with the .DAT file extension.
Programmable parameters are used by the Read/Write Parameters screen for programming into nonvolatile
memory.
Parameter settings are modified from three screen tabs: the Modem tab, Com/Analog tab, and Radio tab.
When desired parameters in each tab window have been adjusted, select the OK button to store the
parameter information into local memory and exit the parameter screen. Clicking the Default Parms button
sets certain parameters back to factory default settings. Clicking Cancel exits the parameter screen without
modifying any parameters currently stored in local memory.
Modem operating parameters include:
Short ID
The user-defined number (1 to 254) that identifies an individual unit in a network.
Comment
Integra-TR Field Programming Software supplies this field for user-convenient description(s): customer
name, location. technical info...). Comments can be text up to 24 characters in length, including spaces.
Compatibility
This field selects the compatibility mode (for use with previous versions of Integras).
z
Integra-TR - used for networks made up of Integra-TR modems
z
Integra-T/TR - used for “on-air” backward compatibility with the Integra-T for bit rates of 4800 and 9600
b/s (full channel units only)
The Integra-TR is capable of selectable network speeds of 2400 and 4800 b/s quarter-channel units, 4800
and 9600 b/s for half-channel units, and 4800, 9600, 19200 b/s for full-channel units. Use the Integra-TR
mode whenever feasible.
Data Delivery
This field determines if data should be delivered to the COM port. Designating a unit as Master or Remote
sets a flag in the header identifying the Unit Type of the originating station:
z
All - this option causes the unit to accept (on the receive side) all data transmissions
z
Selective - this option causes the unit to accept (on the receive side) data only if it originates from a unit
of the opposite Unit Type
Sleep Mode
Sleep Mode is one of Integra-TR’s three low power modes of operation (along with “Reduced Transmit
Power” and “Suspend Mode”). When Sleep Mode is enabled, the unit is in low power consumption
(approximately 7 mA). The unit cannot detect the presence of carrier in sleep mode. Asserting RTS on the
COM or Setup Ports wakes the unit. The unit will receive and decode data within 45 to 65 ms (dependent on
model and temperature) after wake-up.

Part No. 001-4008-101/102
Unit Type
This radio button selects unit type:
z
Remote - Select this option to designate the unit as a Remote station
z
Master - Select this option to designate the unit as a Master station
Designating a unit as Master or Remote sets a flag in the header identifying Unit Type of originating station.
This function is used in conjunction with “Data Delivery” when running certain user protocols.
Tx Online Diags
Transmission of online diagnostics may be enabled or disabled for any unit without affecting its ability to
communicate with other units in a network. At the beginning of each data transmission from a unit,
diagnostics are delivered locally to the units Setup Port regardless of the Tx Online Diags settings. Where
continuous data transmissions are required from a Master unit, diagnostics are sent at 20 second intervals.
Diagnostics information includes:
z
Short ID,
z
Internal case temperature (in Celsius),
z
Battery voltage (in volts),
z
RSSI (in dBm),
z
Forward Power (in watts),
z
Reverse Power Indicator,

Network Speed
This field selects the network speed (bit rate) of the RF link between units. The can vary from the COM Port
baud rate but must be the same for all units in a network:
z
2400 b/s for one-quarter channel models of Integra-TR
z
4800 b/s - selectable for quarter-, half- and full-channel models of Integra-TR and for full-channel models
of Integra-T
z
9600 b/s - selectable for half- and full-channel models of Integra-TR and for full-channel models of
Integra-T
z
19200 b/s - selectable for full channel models of Integra-TR only
Extended Preamble
This field extends transmitted synchronization time when the unit is used in a network with repeaters. The
default is 0 mS and the range is 0 to 100 mS in 5 mS intervals. Add 5 to 10 mS for each Repeater an
Integra-TR communicates through in a network (dependent on user’s protocol).

Figure 2-9 Suspend Mode Timing Graphic
Suspend Period
This field is used to set the period of time until a unit goes to cycled low power mode - range is 50 to 12,000
mS in 50 mS intervals. Setting to a value of 0 disables Suspend Mode.
Activity Timeout
Activity Timeout is used to set the minimum length of time the unit will remain awake in the presence of a
carrier - range is 1 to 255 seconds in 1 second intervals. This field is active only if Suspend Mode is enabled.
A non-zero value must be set to enable Suspend Mode. The same Activity Timeout and Suspend Period val-
ues must be set for both Master and Remote units. See Figure 2-10 for a Suspend Mode Timing graphic.

z
Input - for use on units not equipped with the cooling option - can be used to monitor an external voltage
(0 to 10 volts)
z
Fan Control - regulates an external fan. Factory set (enabled) and the default for all units equipped with
the cooling option. The temperature-controlled open-collector transistor is rated for 100 mA max. The
unit’s internal thresholds are set for ON at 48 degrees C and OFF at 38 degrees C. This selection is
dependent on hardware configuration and should not be changed in the field.

pendent on hardware configuration and should not be changed in the field.
2.4.3.3 Radio Operating Parameters
The Radio tab allows user programming of various radio operating parameters.
Figure 2-12 Radio Setup Parameters Screen
Radio
This field designates the radio model.
2-15
Part No. 001-4008-101/102
Range
This field designates radio frequency range.
Channel
This field specifies whether the unit is quarter-, full-, or half-channel (6.25, 12.5, or 25 kHz).
Transceiver Type
This field configures the transmitting and receiving characteristics of the unit according to network
application:
z
Tx Only - For use in a full-duplex application to disable receptions on the unit used as the transmitter. Tx
Only designation pre-loads the synthesizer and allows faster attack time to speed up transmission response
z
Rx Only - For use in a full-duplex application to disable transmissions on the unit used as the receiver. Rx
Only designation prevents accidental transmissions
z
Transceiver - For use in all other applications
Carrier Sense
Denotes the RSSI level when the unit senses a carrier. Carrier Sense is used for data recovery, in the interpre-
tation of diagnostics, and to turn on the front panel CS LED. The threshold may be raised to prevent false
Carrier Sense operation in the presence of noise, inter-modulation, or other sources of interference (i.e. for
ambient noise at -100 dBm, set the Carrier Sense for -95 dBm).
Tx Timeout
Tx Timeout is used to set maximum period of time the unit will allow in a transmission. The range is 0 to 120
seconds in 1 second intervals (0 being disabled). Tx Timeout is used to protect both the unit and the net-
work in case a transmitter becomes stuck on the air. For Integra-TRs equipped with the cooling option for
extended transmit applications, the Tx Timeout must be disabled.
Rx Frequency
Rx Frequency designates channel pair transmit frequency.
Tx Frequency
Tx Frequency designates channel pair receive frequency
Power
This field designates the channel pair Power Output Adjust value. The default value is 255 (5 watts). This
value should be left at the default value unless lower power is required to meet regulatory requirements or to
increase the allowable transmit duty cycle.
NOTE: Power does not vary linearly with this parameter so some experimentation may be required to
determine the correct power setting.

2.4.7 Radio Parameter Cloning
Figure 2-16 Clone Programmable Parameters Screens
After the initial Integra-TR parameters are programmed, saved, and stored in local memory, other Integras in
the system can be quickly programmed using the cloning option under the Edit pull-down menu. Clone
Programmable Parameters will program the radio with all of the currently loaded parameters except the
Short ID and Comment. The cloning option is useful if there is a need to change the DTE Baud Rate for a
number of radios in a system.
2.4.8 Writing / Reading Integra-TR Parameters
After all radio parameters are setup, select the OK button to store the information into the PC’s
memory. To load parameters into the Integra-TR, initiate a Write Programmable Settings from the
Edit menu or select the Write icon from the Tool Bar. After the programmable parameters are
loaded into the Integra-TR, save the parameter information using the Save Data As option in the
File pull-down menu.The name and location of the file (*.dat extension) will appear on the status bar at the
bottom of the screen.
The Read Programmable Settings command will read parameters from the current Integra-TR and
store the information in local memory. The parameters can be viewed and/or edited with the
Setup Modem/Radio Parameters screens.
Note: Dataradio recommends a Read be done anytime an initial connection is made to the Integra-TR Setup
Port before accessing the Setup Modem/Radio Parameters screen. This will help avoid writing erroneous
parameters to the connected unit.
2.4.9 Offline Link Test
The Offline Link Test is used to test the link between two units: the local unit interfaced to the computer and
a remote unit. Blocks of data are transmitted to the remote unit and the remote unit decodes and returns
them. The transmitted and received blocks of data are compared and the ratio of the results are calculated.
NOTE: An Offline Link Test requires suspension of network operation.
An Offline Link Test returns the following statistics (see Figure 2-17):
Local ID
The Local ID is the Short ID of the unit interfaced to the computer.

2.6 OPTIMIZING YOUR SYSTEM
Detailed system engineering is beyond the scope of this manual. However, there are some simple tips that
can be used to optimize performance of a radio based SCADA or telemetry system.
Choose the best protocol Some SCADA devices allow a choice of more than one operating protocol. In
some cases, performance can be improved by selecting a different protocol. Contact Technical Service for
assistance.
Check timer settings Polling protocols issue a poll and wait a certain time for a response. Integra-TR adds a
short amount of delay to each poll and response (typically in the order of 60 to 70 ms). Timer settings that
are too short may cause erroneous indication of missed polls, in which case the application may retry or
continue to cycle, ignoring the missed station. In this case, the response may collide with the next poll,
further increasing errors. Setting an adequate timer margin will avoid problems and maximize performance.
Avoid flow control Set the Com port baud rate to a value less than or equal to the radio network speed (2400,
4800, 9600 or 19200 b/s). In a polling system, this will prevent buffer overflow with possible missed
transmissions. If the port baud rate must be set higher than the radio network speed, you may have to limit
message length to prevent possible buffer overflow. Integra-TR will exert a flow control signal (CTS
dropped) if buffers are almost full, but not all DTE honor such signals.
Use the highest suitable port baud rate (without exceeding the radio network speed) Operating an RTU at
1200 b/s on a 9600 b/s network will increase data transmission delays and reduce system performance.
Evaluate the need for online diagnostics Enabling online diagnostics increases delays by 2.5 to 10 ms
(depending on speed). In critical applications, this extra delay can be eliminated by disabling online
diagnostics. Offline diagnostics (diagnostics on request) remain available.
SECTION 3
MAINTENANCE AND ADJUSTMENTS
3-1
001-4008-101/102
3.1 OVERVIEW AND MAINTENANCE INTERVALS
This chapter outlines the basic tests and adjustments required upon initial installation and thereafter at
annual maintenance intervals or whenever deterioration in performance indicates that adjustment may be
required. Units are delivered from the factory properly aligned and tested on the frequency range specified
at time of order. Adjustment beyond that described in this chapter is not required unless radio modules have
been tampered with or repaired. In such cases, we recommend complete factory re-alignment as special test
equipment is required. This chapter is intended for use by installation and maintenance personnel.
3.2 EQUIPMENT REQUIRED
The adjustments described below require the following equipment:
1. 13.3 VDC / 5A regulated power supply.
2. Radio service monitor (IFR1200 or equiv.).
3. Cable with SMA male connector to connect Integra-TR to the service monitor.
4. Integra Field Programming Software kit.
5. A PC with Windows 95 or later operating system to run the Field Programming Software.
6. Normal radio shop tools.
3.3 TEST POINT
For trouble shooting aid, there is one test point available at pin 4 of the power/analog connector (white
wire). This demodulated signal measurement is half the voltage read at the RSSI bar graph (found in the
Field Programming Software).
Note: the RX-TP mode must be selected (Analog Connector window) using the Integra Field Programming
Software.
3.4 BASIC TESTS / ADJUSTMENTS
Basic tests and adjustments to be performed are:
1. Transmitter power output
2. Transmitter frequency
3. Transmitter deviation
4. Carrier Sense
5. Demodulated signal level
6. 12 dB Sinad
7. Distortion
3-2
Part No. 001-4008-101/102
3.5 PRELIMINARY STEPS
Important Note: Before proceeding make sure that the service monitor has been calibrated recently and has
warmed up for at least the time specified by its manufacturer. Some reported frequency and deviation
problems have actually been erroneous indications from service monitors that have not adequately warmed
up. This is particularly likely when field service is done during winter months.
1. Connect the Integra-TR antenna connector to the radio service monitor RF input using a 023-3410-118 or
equivalent 50-ohm cable. That input should be able to support at least 5 watts.
2. Connect Integra-TR to the power supply and adjust the supply voltage to 13.3 volts.
WARNING: Do not exceed 16 VDC during setting-up for tests and adjustments.
3. Using a 9-conductor straight RS-232 cable, connect the unit's Setup port to the RS-232 port of a PC and
run the Integra Field Programming Software on the PC.
4. Press GET for the unit configuration.
5. From the Settings menu command, click on Radio Settings, set the frequency to be used for testing. Leave
this window open and on top.
6. Follow the steps in Table 7.
3.5.1AFTER ADJUSTMENTS ARE COMPLETED
Adjustments made using the Field Programming Software are temporary and must be made permanent as
follows:
1. After all adjustments are completed satisfactorily, press “PUT” to save the changes permanently
to the unit.
2. Press Station Reset to activate all configuration changes.
WARNING: The frequency band 406 to 406.1 MHz is reserved for use by distress beacons and should not
be programmed into the unit.

NETWORK TROUBLESHOOTING
4-1
001-4008-101/102
4.1 TROUBLESHOOTING OVERVIEW
The Field Programming Software provides help for the user to find problems on individual units within a
network. This program runs (only) from the Integra Setup port.
Here is a list of tests that a user (having network communication problems) can try while using this
software utility:
With user network application's running:
z
Monitor the current network activity by using online diagnostics monitoring feature
z
Gather diagnostics (i.e. local GET Status) from the unit connected to and check that they are within
tolerances
With user network application offline:
z
Check communication link between two units (i.e. Link test)
z
Gather remote diagnostics (i.e. Remote GET Status) from a “suspect” remote unit and check that they are
within tolerances
z
Check RF signal strength of a particular remote unit transmitting a continuous unmodulated test carrier
(i.e. Remote Carrier button)
z
Check RF power output from the connected unit by using the Carrier test button. The RSSI bar graph will
turn to a divided wattmeter (Forward and Reflected power)
z
Check carrier frequency from the unit connected by using the Carrier button and a RF communication
test set
z
Check transmit deviation from the unit connected by using TX Tone button and a RF communication test
set
4.2 INTDIAG
The Field Programming Software is divided into two distinct parts: the Online and Offline diagnostics.
4.2.1 ONLINE DIAGNOSTICS
Online diagnostics may be used for monitoring an operating network with the user’s applications running.
The diagnostics are piggy-backed (carried along with user data transmissions) and do not interfere with
day-to-day operations. Refer to Table 4-1 for diagnostics, descriptions, and tolerances.
Maintaining a registry listing typical diagnostic readings for a network is an effective tool for comparing
test readings and trend monitoring (system history). Variances in the data displayed can alert technicians to
changes in network status. Earlier detection leads to earlier intervention.
4-2
Part No. 001-4008-101/102
4.2.2 OFFLINE DIAGNOSTICS
Offline diagnostics are used for trouble-shooting and test transmissions to remote units or to a local
connected unit. Offline diagnostics are intrusive as they take control of radio channels. User applications
must be offline.
4.3 GET STATUS
The Get Status function allows the user suspecting network communications problems to gather diagnostics
and check tolerances as follows:
z
Local GET Status: gathers diagnostics from the unit connected to the network
z
Remote GET Status: gathers diagnostics from a suspect remote unit connected to the network
Values displayed are taken at the moment the GET Status button is pressed. The GET Status does not
continuously update. Press the Clear button and press GET Status again to update the information.

4.4 OFFLINE LINK TEST
Tests the network data link status by sending a number of transmissions to a remote unit, back from the
remote, computing a ratio of good to bad signals received and displaying the result as a link quality for both
individual links as well as the overall link.
Caution: Shut down your application before pressing “Link Test”.
Before starting a Link Test:
1. Ensure that the Radio Source selected is “Remote”.
2. Click in the active Short ID field and enter the address of the desired remote unit.
3. Press the “Link Test” button to start transmitting blocks of data.
The selected remote decodes and returns data blocks. Transmission will continue until the link test button is
pressed again or after 100 data blocks are transmitted. The sent and received data are compared and the ratio
of good to bad blocks are calculated. The error rate is calculated separately for each direction and for the
link as a whole. The results are displayed on the message screen in the format detailed in Table 4-2.

Table 4-2 Link Test Display Format
4.5 BAR GRAPH
A Received Signal Strength Indicator (RSSI) bar graph is available during continuous test transmissions
(i.e., remote “Tx Tone” and “Carrier”). The appearance of the “Local RSSI” indicator is a single vertical
graph bar with indicated values in “dBm”. The accuracy of the reading is normally better than +/- 3db.
The bar graph changes during user maintenance local test transmissions of “Tx Tone” and “Carrier”. A split
screen of two parallel vertical bars is seen. The “Local TX Pwr” measurements of “Forward power” and
“Reflected power” are in “Watts” (see Figure 4-1).
4.6 CARRIER
To send an unmodulated carrier, press the “Carrier” button. Used mainly to check carrier frequency, RF
power level (local unit) and received signal strength from a remote unit.
Warning: Care must be taken while reading transmit deviation remotely. Over-the-air service monitor
readings may give higher results than expected because of RF noise and interference that superimpose
on the received signal.
z
If Source is “Local”, pressing Carrier transmits until the button is pressed again
z
If Source is “Remote”, the selected unit will send for 30 seconds. Remote transmissions cannot be
interrupted
All buttons are inactive during test transmissions.
4.7 TX TONE
The TX Tone is used mainly to check transmit deviation. To send a modulated carrier, press the “TX Tone”
button (see Figure 4-1).
z
If Source is Local, sends a 1200 Hz sine wave for 30 seconds or until the button is pressed again
z
If Source is Remote, causes the selected ID remote to send a tone for 30 seconds. Remote transmissions
cannot be interrupted. All buttons are inactive during test transmissions. Typical transmit deviation are
network speed dependant and are shown in Table 4-3.

CIRCUIT DESCRIPTION
6-1
001-4008-101/102
6.1 OVERVIEW
Section 6 describes the circuit operation of the logic board. This section is intended for use by engineering
and service personnel.
6.2 CIRCUIT DESCRIPTION
Refer to Figure 6-1 for the block diagram of the Integra-TR Logic Board.
6.2.1 MICROPROCESSOR CIRCUIT
The microprocessor contains two Z84015 CMOS low power Intelligent Peripheral Controllers (IPC). Each
IPC is an 8-bit microprocessor integrated with CTC, SIO, PIO Clock Generator Controller and Watch Dog
Timer.
One of the Z84015s (U17) is used in the normal mode. The other Z84015 (U21) is used in the evaluation
mode and only the CTC, SIO and PIO sections are used. The CPU section is disabled.
The first Z84015 Clock Generator uses a 19.6608 MHz crystal that provides a CPU clock rate of 9.8304
MHz for both Z84015s. The 9.8304 MHz clock is further divided by 2 to feed all 8 CTC (4 in each Z84015).
The 64K-memory space of the Z84015 is divided into two blocks of 32k each. The lower 32K are used for
the firmware program and the upper 32K by the CMOS RAM (U18). The memory IC used for the program
is a CMOS FLASH (U22) with 1024 sectors of 128 bytes each.
The dual Z84015 circuit provides up to 8 Counter Timer Channels (CTC), 4 Serial Input/Output (SIO) and
32 Parallel In-put/Output (PIO) lines.
The CPU also provides the clock for the CPLD modem.
6.2.2 RS232
The RS232 IC (U15) is used to interface the application DE-9 connector to the SIO_B section of U17, and
the set-up DE-9 connector to the SIO_A section of U21. Two receivers remain enabled in sleep mode to
ensure fast wakeup.
6.2.3 MODEM
The modem section is used to interface the serial digital data to the transceiver.
The CPLD modem IC (U16) with a programmable Raise-Cosine filter (U10) operates in DRCMSK mode at
2400, 4800, 9600, and 19200 bits/sec. It incorporates a 7-bit hardware scrambler and uses Differential
(NRZI) encoding in DRCMSK mode to minimize data pattern-sensitivity. An electronic potentiometer U5B
6-2
Part No. 001-4008-101/102
(E-Pot), controlled by CPU U17, is used to set the transmitter deviation by amplitude adjustment of the
baseband signal. Electronic potentiometer U5C is also provided to fine adjust the RF carrier frequency.
6.2.4 TRANSMIT & RECEIVE DATA
Transmit Data from the RS-232 port is level-shifted to TTL by U15 and passed through the CPU for further
processing and conversion from asynchronous to synchronous format. The CPLD modem, U16, takes the
digital data stream from SIO-A of the CPU and synthesizes to the constant-amplitude analog baseband
signal. The synthesized data stream is filtered by U10, buffered by U9B, and applied to radio module TXA
at P1-6.
Received signals are applied to the RXA pin on P1-13 and amplified by U3A. U3A gain is set by the
electronic potentiometer, U5D, and filtered by U10. The same filter circuit is used for transmission and
reception. Two analog multiplexer/demultiplexer gates (U8A and B) controlled by TX_EN line are used for
sharing. The filter U10 cut-off frequency is programmable by the CPLD, based on the data rate. The analog
signal is buffered by U1D and fed to Peak Detectors U3C, U3D, and U3B, and to slicer circuit U1C via
U1B. The raw data is passed to the CPLD modem (U16) for de-scrambling and receive clock recovery. The
resulting synchronous bit stream is fed to CPU SIO-A for further processing and conversion to
asynchronous format before delivery to the RS-232 driver and to the user port.
6.2.5 INTEGRA-TR A/D AND DIGIPOT
An 8 channel, 8-bit successive approximation A/D converter, type ADC0838 (U4), is interfaced to CPU
(U17) and Peripheral (U21).
CH0 and CH1 are connected to the positive and negative peak detector of the modem section. The software
can read the positive or negative value of an RX signal, or using the differential mode, the actual peak-to-
peak RX signal value.
CH3 is used to measure the radio RSSI signal which was amplified by U7A.
CH4 is connected to the radio diagnostic signal (P3-14). This pin is used to output an analog signal
corresponding to the power output and the reflected signal.
CH5 is connected to U6 (LM50), a temperature sensor with a -40 to +125°C range.
CH6 is used to read the SWB+ voltage after proper scaling into the 0-5 V range.
CH7 and CH8 are connected to EXT SIGNAL 1 and 2. A 2:1 divider and protection circuit is inserted
between both external signals and the A/D.
The External Signal (pins 1 and 2) is also connected to U21 at PB6 and PB7 through transistors Q3 and Q4
and can be used for Analog Input or Digital Output.
EXT_SIGNAL 2 is also connected to the Rx test point RX-TP through U8A (74HC4066). Under software
control, the RX-TP (scaled down by 2) is available on the power connector for trouble-shooting purposes.
A 4-channel digital potentiometer type (U5) is used to adjust the RX Signal, TX Modulation, Carrier
Frequency and Carrier Detect Threshold.
6-3
Part No. 001-4008-101/102
An 8 channel, 8-bit successive approximation A/D converter, type AD0838 (U9), is interfaced to CPU
(U18) and Peripheral (U20).
U19 generates a power-on reset for the CPU and U6 is a temperature sensor used by the firmware to
compensate for variations in RSSI.
The RSSI signal from the transceiver is amplified and filtered by U7A. The signal is compared to a
threshold value set by digital potentiometer (U5A). The output of the comparator (U7B) is used to change
the hold time of both peak detectors at the beginning of the receive packet.
6.2.6 WAKE-UP CIRCUIT
The wake-up circuit for the Integra-TR consists of a 50 ms monostable circuit that is triggered by the rising
edge of a Sleep signal from CPU (U17). The falling edge of this 50 ms pulse (end of pulse) is connected to
the NMI of the CPU and will wake up the CPU from Sleep mode after 50 ms.
When exiting SLEEP mode on a \NMI, the CPU firmware will increment a counter, then return to Sleep
until it reaches a limit set by a software parameter. When the programmed count is reached the CPU will
wake up the radio and the RS232 driver, program the synthesizer, and watch for channel activity.
While in sleep mode (during the 50 ms pulse), an active RTS from either communication port will reset
(terminate) the 50 ms pulse so that its falling edge will restart the CPU immediately.
The CPU will check to see if either RTS signal is valid each time it is restarted by the \NMI. The firmware
will only start the sleep timer after checking that all “wakeup” inputs are inactive.
6.2.7 POWER SUPPLY
The 13.3-volt DC power input is protected by a 3-amp fuse and reverse-protected by a diode.
A 5 volt, low voltage regulator (U12) is used to power all digital functions and another 5 volt, low voltage
regulator is used to control the analog +5V_SW voltage in the sleep mode.
