MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMITS
Do not transmit with this basestation and antenna when persons are within the MPE Radius of the antenna. The MPE Radius
is the minimum distance from the antenna axis that ALL persons should maintain in order to avoid RF exposure higher than
the allowable MPE level set by the FCC.
WARNING
FAILURE TO OBSERVE THESE LIMITS MAY ALLOW ALL PERSONS WITHIN
THE MPE RADIUS TO EXPERIENCE RF RADIATION ABSORPTION, WHICH
EXCEEDS THE FCC MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMIT. IT IS
THE RESPONSIBILITY OF THE BASESTATION OPERATOR TO ENSURE THAT
THE MAXIMUM PERMISSIBLE EXPOSURE LIMITS ARE OBSERVED AT ALL
TIMES DURING BASESTATION TRANSMISSION. THE BASESTATION
OPERATOR IS TO ENSURE THAT NO BYSTANDERS COME WITHIN THE
RADIUS OF THE MAXIMUM PERMISSIBLE EXPOSURE LIMITS SHOWN BELOW.
DETERMINING MPE RADIUS
THE MAXIMUM PERMISSIBLE EXPOSURE RADIUS HAS BEEN ESTIMATED TO BE A RADIUS OF 24 FEET
MAXIMUM ASSUMING THE HIGHEST EFFECTIVE RADIATED POWER (ERP) ALLOWABLE UNDER FCC
RULES FOR BASESTATION ANTENNA INSTALLATIONS. THIS ESTIMATE IS MADE ASSUMING
MAXIMUM ALLOWABLE ERP LEVEL BY THE FCC AND 100 PERCENT DUTY CYCLE. THE MPE
CALCULATIONS WERE MADE ASSUMING WORST CASE IN EACH BAND WITH RESPECT TO
FREQUENCY, ERP AND LIMIT. THE MAXIMUM ALLOWABLE ERP WAS DETERMINED FROM THE
APPLICABLE PART 90 RULES REGARDING POWER LIMITATION ( 90.205, 90.309, 90.635 ). THE LIMIT
USED WAS FOR UNCONTROLLED EXPOSURE. THE FORMULA USED WAS DERIVED FROM OET 65,

INTRODUCTION
This manual describes the installation and
connections for a typical MASTR III station combination.
Information provided includes suggested locations and
installation of equipment and hardware, interconnection
and assembly diagrams, alignment instructions, and
troubleshooting suggestions.
The MASTR III cabinet normally includes the
Transmitter/Receiver Shelf, the Transmitter Power
Amplifier, and a Station Power Supply. The assemblies
are mounted in a 37-inch cabinet. Optional 69- inch or
two stacked 37-inch cabinets are available.
CABINET
The system is contained in a 37-inch cabinet with
improved ventilation for greater reliability. The cabinet
can also house optional equipment such as a Duplexer,
Charger, Gell Cell batteries, or Auxiliary Receiver.
STATION POWER SUPPLY
The Station Power Supply provides all necessary
power to run the station. It provides 13.2 volts at 33 amps
to the station from an AC source. The source voltage
depends on the particular area and power sources
available. The power supply is normally mounted beneath
the T/R Shelf.
UNPACKING EQUIPMENT
Unpack the station and carefully inspect each item. If
any damage has occurred to the equipment during
shipment, immediately file a claim with the freight
carrier. AC power adequate to meet system requirements,
environmental control, and digital or voice grade phone
lines must be available at the site prior to installation.
SITE PREPARATION AND
INSTALLATION
CABINET INSTALLATION
The MASTR III station cabinet is designed for
servicing from the front. However, the system may also
be serviced from the rear when adequate space is
available. The cabinet should be mounted on a level, solid
surface.
If rear servicing is desired, cabinets should be setup
with a minimum of 24-inches of clearance in the rear and
between cabinets or wall to permit ventilation and room
for the service-man to move between and behind the
cabinets.
If space is at a premium or if servicing is to be made
from the front only, then cabinets should be setup with a
minimum of 18-inches of clearance in the rear and 12inches between cabinets to permit ventilation. However,
access to the rear of the cabinets may still be necessary in
order to install or repair antenna or power cables.
Single and double stacked 37-inch cabinets must be
securely anchored to the floor according to the footprint
shown in Figure 2 and following single or double stacked
installation instructions.
TRANSMITTER/RECEIVER SHELF
Single 37-inch Cabinet Installation
The MASTR III Transmitter/Receiver (T/R) Shelf
contains the station control electronics for dc/tone remote,
re-mote/repeater, or repeater only applications. The
station control electronics consists of a Backplane board,
Power Module, System Module, and an Interface Board.
The back-plane also connects the RF Section which
consists of the Receiver Synthesizer Module, First IF
Module, Second IF Module, and the Transmit Synthesizer
Module.
The station provides for front and rear door servicing
or front door only servicing in tight space situations. The
front and rear of the station must be kept clear of
obstructions so that the serviceman can easily remove the
front and rear doors for servicing. Also, the front and rear
air vent louvers and rear cable outlets must be free of
obstructions.
TRANSMITTER POWER AMPLIFIER
The Transmitter Power Amplifier is mounted directly
behind the T/R Shelf. Cabling from the output of Power
Amplifier will depend on the system configuration.
10
LBI-38636S
serviceman can easily remove the front and rear doors for
servicing. Also, the front and rear air louvers and rear
cable outlets must be free of obstructions. Leave a
minimum of 12-inches of space on each side of the
cabinets to avoid obstructing the louver air vents. With
the bottom cabinet in position, secure it to the floor as
shown in Figure 2 with 1/2-inch bolts and anchors.
Remove the four plastic plugs in the top surface of the
bottom cabinet (by squeezing the plastic retaining barbs
together from the inside of the cabinet and pushing the
plug up and out).
Position the top cabinet on the bottom cabinet. Align
the fixing holes and bolt the cabinets securely together
using 1/2 inch bolts, washers, and locknuts (supplied in
hardware kit 344A3450G7) as shown in Figure 4.
Figure 2 - 37 Inch Mounting Footprint
It will be necessary to remove the front and rear
covers and some internal components to allow access to
the top and bottom securing holes.
Figure 3 - 37-Inch Cabinet
Using the four holes are provided in the bottom
surface of the cabinet, the cabinet must be securely bolted
to the floor with 1/2" bolts and anchors as shown in
Figures 2 and 3. It will be necessary to remove the front
and rear door covers and some internal components to
allow access to the bottom securing holes.
Double Stacked 37-inch Cabinet installation
For limited floor space situations, two 37-inch
MASTR III cabinets may be stacked one upon the other.
This requires that the bottom cabinet be securely bolted to
the floor surface and the top cabinet securely bolted to the
top surface of the bottom cabinet, as shown in Figure 4.
Figure 4 - Stacked 37-Inch Cabinets
Ensure first that the floor is strong enough to support
the weight of the two cabinet configuration and that
adequate ceiling height is available. Ensure the front and
rear, of the station cabinets are clear of obstructions so
11
LBI-38636S
ELECTRICAL CONNECTIONS
AC Power
The station will be received with the power cord
bundled and stored in the bottom of the cabinet. Remove
the twist tie from the AC power cord, unravel and feed the
cord through one of the rear cable holes. It may be helpful
to remove the grommet from the hole before passing the
cord through and reinstalling it afterwards.
A separate 15 to 20 Ampere, 120 Vac, 60 Hertz
electrical circuit should be provided for the station. A 120
volt grounded AC outlet for the station should be located
within six feet of the lower rear of the cabinet. The power
cord for the 120 Vac Power Supply comes with a
grounded 120 Vac molded plug attached. Check the
electrical code to ensure the power outlet complies with
local ordinances.
TELEPHONE LINE CHARACTERISTICS
Telephone Lines
The type of telephone lines required for the
installation will depend on how the station is controlled
and if it is being used for simplex or duplex operation.
Generally, both 4-wire Audio and E & M Signaling
options are used to interface between the radio and carrier
systems. However, 2-wire Audio can be used in the twoway radio portion of the control system if hybrids are
installed to provide transition between the 2-wire and 4wire connections. Usually the E & M Signaling is
separated from the audio (separate line) in both 2-wire
and 4-wire installations.
If a 240 Vac, 60 Hz source is used for the station, an
external step-down transformer (similar to 19C307148P1)
must be used.
For 230 Vac, 50 Hz applications, the station power
supply is equipped with a power cord, less connector, to
permit connection to an acceptable electric circuit. A plug
meeting local electrical codes must be supplied by the
customer. Make sure the station power supply is
connected to an outlet having the same configuration as
the plug. No adapters should be used in this configuration.
The equipment should be connected to a good earth
ground using a ground wire of adequate size. A ground
stud is provided for a separate cabinet ground. Use No. 14
or larger wire (depending on local ordinances and system
requirements) for connecting the cabinet to a good
building ground. After the ground lead from the power
cable is connected to the building ground, check for
continuity between building ground and the cabinet.
Microphone
The local microphone or utility handset may be
attached to the station through the MIC port on the front
of the T/R Shelf (Figure 6), the connections are shown in
Figure 5.
Antenna
The antenna cable may be routed through the top rear
or bottom rear of the cabinet directly to the appropriate
connector within the station, depending upon the
configuration.

Types Of Voice Grade Lines
Telephone lines are normally obtained from a
communications common carrier ("telephone company"
for our purposes here). When a voice grade (as contrasted
to a "data line") telephone line is requested, there is no
way of knowing just what type of line will be received
from the phone company.
In addition, the telephone company may supply one
type of line first, and later change it to another type
without any notification to the user. One of the following
types of telephone line can be expected:
1. Wire lines with no amplifiers
2.
Wire lines with amplifiers added to compensate
for line loss
3.
Facilities derived from carrier (multiplex)
These lines have different operating characteristics,
and each must be treated differently. In large systems, all
three types of lines can be provided. In long haul
applications, a system can consist of two or three of these
types of lines in tandem (tied together end-to-end).
The first type is WIRE LINE WITH NO
AMPLIFIERS. These are the same lines that have been
used for years to control dc systems. These are the easiest
to work with since they include no problem-causing
electronic equipment. These lines are normally found in
LBI-38636S
less populated areas where the phone company has not yet
switched to carrier systems. These lines have a fixed
amount of loss, which varies with frequency, temperature,
from deterioration of splices, and from moisture getting
into the cables. When these cables get old, the phone
company sometimes applies DC current to improve the
joints and lower the line loss. In this case, the line is not
usable for DC control.
Normally, a +10 dBm test tone can be applied to
these lines. These lines do not normally include any type
of voice limiters.
The second type of line is a WIRE LINE WITH
AMPLIFIERS. These lines are normally supplied when
the loss of available lines is too high. An amplifier or
several amplifiers are added to the line to make up for the
loss.
One commonly used amplifier is the E-6 repeater.
This amplifier will pass DC current and they have been
used on DC lines for years. These amplifiers include
limiters, which start limiting at somewhere around 0 dBm
input to the amplifier. The limiters do not cause any real
problems on DC systems since only the voice peaks are
clipped. However, special care must be used when
applying them to tone remote control systems.
Each amplifier can be adjusted for up to 12 dB of
gain. If the loss is more than 12 dB, one or more
amplifiers may be added. The amplifier(s) can be placed
at any point in the line.
The third type of telephone line is a Derived Facility
using carrier equipment. Since this is the most
complicated, more care is required when connecting radio
equipment. This type of line will be available more often
in the future.
The telephone company supplies two wires at each
end of the circuit. Each two-wire end goes to some point
in the circuit where it is converted to a four-wire circuit
and then connected to the carrier equipment. A four-wire
circuit can be ordered if that is what is required. At the
other end, it is taken out of the carrier equipment and
converted back to the two-wire circuit. The carrier
equipment has a transmit path and a receive path. The
gain is adjustable each way.
Figure 6 - T/R Shelf Connections

LBI-38636S
The telephone company wants to see a maximum
three-second level of -13 dBm at the carrier equipment as
measured on a modified Western Electric 3-type Noise
Measuring Set. The telephone equipment will limit the
audio if the signal is above -13 dBm at the carrier input.
This does not mean that the maximum that can be applied
into the two-wire end is -13 dBm. If the radio equipment
is a good distance from the carrier equipment, there will
be some line loss. If the loss is 5 dB, for instance, then -8
dBm could be applied into the two-wire end. Therefore,
the telephone company will have to be asked in each case
what level is allowed to be applied at the two-wire end.
If the telephone company checks and finds that too
much audio is being applied into the carrier equipment,
they will put a pad into the circuit to cut the audio down.
When the phone company is asked what levels can be
applied to the line, they will either provide a level in
Volume Units (VU) or test tone. VU is average voice,
which is generally considered to be 10 dB below test tone.
Test tone is a 1000 or 1004 Hz tone used to line up the
circuit. Test tone is normally given in dBm. If the radio
installer isn’t careful, he and the phone company will be
talking 10 dB apart. If the phone company says the limit
is 0 VU, use +10 dBm for the line-up.
The two wire ends of these lines are normally
designed to work with a 600 ohm impedance in and out.
The transmit and receive carrier equipment gains are set
up for 600 ohm terminations. If the line to the carrier
equipment is fairly long, the impedance at which at the
two-wire end is not very critical.
If the two-wire end is close to the carrier equipment,
however, then the impedance is critical. If the impedance
is not 600 ohms, it can cause the gain of the carrier
equipment to go up or down. In some cases, feedBack
(oscillations) from the receive path to the transmit path
will be present. A common problem that causes
oscillations in the carrier equipment is gain change,
whether from misalignment or other reasons.
American Telephone and Telegraph Company has
published a reference for Voice Grade Lines entitled,
"Private Line Interconnections, Voice Applications"
(Publication Number 43201). It covers several types of
private line interfaces. There is no publication that covers
radio control alone. However, there are several
parameters provided in the publication that are important
to note.
The 1000 Hz loss design objective is 0 to 10 dB. If
the loss is not specified, there will be a loss of 10 dB at
1000 Hz in most cases. The phone company allows itself
a SHORT-TERM fluctuation of 3 dB and a LONGTERM variation of 4 dB. If a 10 dB loss line at 1000 Hz
is specified, up to 14 dB loss can be expected, and the
phone company would still be within their design limits.
14
The loss between 500 and 2500 Hz can be +2 dB and
-8 dB relative to 1000 Hz loss. Note that the phone man
may refer to this as -2 and +8 in the telephone company
way of talking. The loss between 300 and 3000 Hz can be
+3 dB to -12 dB relative to the 1000 Hz loss. This says
that if there is a line with 10 dB of loss at 1000 Hz, a loss
of as much as 18 dB at 2500 Hz, and 22 dB of loss at
3000 Hz can be expected. A loss 4 dB of long-term
variation should be added to this.
Noise on this type of line is measured at each end
with a Western Electric 3-type Noise Meter. The
allowable level of a line from 0 to 50 miles is 31 dBrnC,
and for a line from 51 to 100 miles is 34 dBrnC. If this
type meter is not available, an AC- VTVM can be used. If
there is a noise reading of -50 dBm or less, generally this
is considered an acceptable circuit.
Tone Remote Control Systems
In contrast with DC systems, where audio level
setting is not as critical, it is important that levels in tone
applications be set properly. Failure to do so results in the
control function not working properly. For example, after
the installation when the user has gained a little
experience, the user may find that they are not always
picking up the function selected. A little extra time spent
at the installation will save many problems of this type
later.
This equipment is designed so that the tone sequence
consists of either two or three parts. The first part is the
"Secur-it" tone (2175 Hz) which is sent at the highest
level for approximately 125 milliseconds. This is
followed by the "Function" tone which is sent at a level
10 dB lower for approximately 40 ms. In the case of a
transmit function, the "Function" tone is followed by
2175 Hz "Hold" tone at a level 30 dB down from the
"Secur-it" tone burst (therefore, it is 20 dB down from the
"Function" tone burst). This tone continues for the
duration of the transmit function. The average voice (0
VU) is sent at the same level as the "Function" tone,
therefore, the test tone for the voice is sent at the same
level as the "Secur-it" tone.
The "Secur-it" tone must arrive at the base station at
no less than -20 dBm. The transmit "Hold" tone must
arrive at the base station at no less than -50 dBm. The test
tone for the voice must arrive at the base station at no less
than -20 dBm. Therefore, the limits of system operation
are usually established by only three things:
1. The maximum level at 2175 Hz that the phone
company will allow to be sent from the most
distant point in the system. Normally this will
not be higher than 0 dBm. In some cases it can
even be less, or on rare occasions it can be +5 or
+10 dBm.
LBI-38636S
2.
The loss of the circuit at 2175 Hz. Do not forget
the long-term variation of up to 4 dB more.
3.
The requirement that the "Secur-it" burst must
arrive at the base station at no less than -20 dBm.
Normally, most systems will not crowd these limits.
However, if the result is a few dB short, consider adding
C-1 conditioning (at an added cost). Resist the natural
desire to just turn up the tone sending level as this will
cause improper system operation.
Increasing the level will cause the "Secur-it" tone
burst to go into limiting in the phone company equipment.
The limited tone causes the "Secur-it" tone filter in the
base station to ring. This will result in picking up or
dropping out functions, which were not selected. NEVER
allow the "Se-cur-it" tone to be in limiting.
There is an easy way to check and see if the "Securit" tone is in limiting. With the phone lines connected to
the equipment at both ends connect an AC voltmeter
across the phone line at the base station. Arrange to send a
burst of "Secur-it" tone long enough to measure the
incoming level on the AC voltmeter. Then arrange to send
a burst of 1950 Hz "Function" tone long enough to
measure the incoming level on the AC voltmeter. If the
1950 Hz tone does not arrive 10 dB (1 dB) less than the
"Secur-it" tone, then the "Secur-it" tone is in limiting. It
will become necessary to lower the sending level at the
remote controller until it is below limiting.
If the audio is high enough to cause the telephone
equipment to go into limiting, it will cause amplitude
distortion. On a high loss line the amplitude distortion
will cause the "Hold" tone (2175 Hz) to vary and the
transmitter to drop out.
On remote systems using tone control, care must be
used when connecting two telephone lines in tandem. For
example, for a base station and two remotes, a phone line
is ordered to connect the station to the first remote, and a
second line to connect the second remote to the first
remote. The loss of each line is now added together and
the tones from the second remote can not operate the base
station. The installer can either specify a low loss on each
line, or run each line directly to the base station.
A check with the phone company can determine
which approach is the least expensive over a period of
time; i. e., an analysis of non-recurring costs versus
recurring costs over the expected length of time the circuit
will be used.
selector 3 dB lower than the 1000 Hz test tone level. Most
telephone lines have a frequency response which
attenuates the 1950 Hz tone with respect to a 1000 Hz test
tone, therefore care should be taken to ensure that the
correct levels are received at the voting selector.
If the telephone company will not allow a continuous
tone as high as -8 dBm to be sent, then a lower loss circuit
should be requested or C-1 conditioning added.
When ordering phone lines for a voting system, if
possible, all lines should be of the same type. Different
telephone line responses will cause the voter to prefer one
signal over others.
It is improper system design to have the received
signal selection biased by a "poorer" telephone circuit.
Many telephone companies will add pads to build out the
lines. If this is considered when the lines are ordered, it
should not be difficult to build all of the lines out to have
the same frequency response.
Ordering Voice Grade Telephone Lines
If a standard voice grade circuit is ordered, and the loss is
not specified, the following will normally result:
1. Loss at 1000 Hz will be 5 to 10 dB; normally 10
dB
2.
Long-term variation 4 dB
3.
Amplitude distortion (frequency response)
Referenced to 1000 Hz; + = more loss 300 to
3000 Hz: -3 to +12 dB 500 to 2500 Hz: -2 to + 8
dB
4.
Noise: 31 dBrnC maximum
5.
Frequency translation error: 5 Hz
6.
Normal impedance: 600 ohms
7.
Maximum permitted signal into the line: -6 dBm
to -13 dBm in-band three second average (the
level arriving at the carrier equipment cannot be
more than -13 dBm).
By adding C-1 conditioning, the loss changes to:
Amplitude distortion (frequency response) Referenced to
1000 Hz; higher frequency = more loss 300 to 2700 Hz: 2 to +6 dB 1000 to 2400 Hz: -1 to +3 dB
One added advantage to C-1 conditioning is that the
voice quality will be improved by boosting the high
frequency components.
Voting System Considerations
A voting system uses a continuous 1950 Hz tone on
the telephone line when the receiver is squelched. This
voting tone is normally sent from the station to the voting

Two-Wire Operation
For two-wire operation, connect the pair to TB101-3
and -4. If the remote control unit at the other end is an
RCN 1000, use J3-3 (red) and -4 (green). Refer to
Methods 1 and 2 in Table 1 and associated illustration for
examples (Figures 8 & 9). Jumpers should be placed on
P104-1 to P104-2 and P105-1 to P105-2 on the Interface

Board connectors and jumpers.
NOTE
Polarity must be maintained, if the metallic
control pair is being used for DC control.

E & M Signaling
E & M lead signaling systems derive their name from
certain historical designations of the signaling leads on
circuit drawings. An "M" lead is associated with the
transMit function or Mouth, while the "E" lead is
associated with the recEive function or Ear. In two-way
radio systems with remote control, E & M Signaling can
be the only type of control offered by the available carrier
circuits.
Generally, both 4-Wire Audio and E & M Signaling
options are used to interface between the radio and carrier
systems. However, 2-Wire Audio can be used in the twoway radio portion of the control system if hybrids are
installed to provide transition between the 2-Wire and 4Wire connections. Usually the E & M Signaling is
separated from the audio (separate line) in both 2-Wire
and 4-Wire installations.
Figure 7 illustrates a typical interface between a twoway radio system and a multiplex/microwave system. The
Remote Control Console and Base Station are equipped
with the E & M Signaling Option and the 4-Wire Audio
Option. The console provides a regulated -48 Vdc output
(or -24 Vdc with minor modifications) to the "M" lead
when the TRANSMIT switch is pressed. This -48 Vdc
activates a tone encoder (usually 3825 Hz) in the
multiplex rack. The tone encoder modulates the carrier
frequency, which is transmitted over the microwave link.
At the station end of the microwave link, the signal is
demodulated and the 3825 Hz tone operates a tone
decoder in the multiplex rack. The output of the decoder
results in a contact closure, which applies +48 Vdc (or
+24 Vdc) to the control shelf. This voltage should be
connected between TB101-1 and TB101-6 on the
Interface board. Jumpers on P104 and P105 of the
Interface Board should also be removed. If +48 Vdc is
being used, resistors R116 and R118 on the Interface
Board should also be removed.
When the system is configured in this manner,
approximately +8 milliamperes flows through the DC
control decode circuitry on the backplane. This will cause
the T/R Shelf to decode a +6mA control current to key the
transmitter and route line audio to the transmitter.

When the control shelf is used with a four wire tone
re-mote/console, the remote control transmit pair (which
modulates the transmitter) should be connected to TB1012 and -5. The remote control receive pair (which listens to
the receiver) should be connected to TB101-3 and TB1014.

When the control shelf is used with a two wire tone
re-mote/console, the remote control pair should be
connected to TB101-3 and TB101-4.

STATION SETUP
The MASTR III station comes pre-programmed and
ready to install, the only adjustments needed are the
required Line Output Level, the Line Input Level
necessary to produce Standard Deviation, and the Line
Cancellation for 2-wire Tone Remote Orientation. These
adjustments can be made using the PC Programming
option TQ-3353, or Utility PC software TQ-0619 with the
Utility Handset SPK9024.
If the system requires control by a remote unit,
the following interconnection must be made.
Connect the wires from the remote unit to the
six-pin terminal block (TB101). Use the
following information when making
connections:
TB101, Pins 3,4 - Line Input/Output for 2-wire
DC and Tone control.
or
Line Output for 4-wire DC and Tone control.
TB101, Pins 2,5 - Line Input for 4-wire DC and
Tone control.

ALIGNMENT PROCEDURE
Alignment of the MASTR III base station was
performed prior to shipment. The factory assumed the
following characteristics:
1. There is no loss or gain for repeated audio
deviation.
2.
3.
If a remote exists, it is connected to the base
station through a telephone line with 10 dB of
loss.
The base station drives the line output at -10
dBm with nominal receive deviation.
The base station should deliver –10 dBm to the line
with a signal applied with 3kHz deviation. A –10 dBm
audio signal applied to the Station Line In should result in
transmitter deviation of 3 kHz.
These values may be altered by following one of the
alignment procedures as provided. For minor adjustments
you may want to adjust only one or two digital
potentiometers or leave the setting as set. In any case, it is
important to carefully examine the ALIGNMENT
DIAGRAM (Figure 15) which follows:

Test Equipment Required
The following test equipment is required to align the
MASTR III base station:
• Audio Oscillator
•
AC Voltmeter
•
RF Signal Generator
•
Deviation Monitor
•
Handset or PC Computer (with diagnostic utility
TQ-0619)
Procedure
Terminate both the Line Input (T101-3,4) and Line
Output (T101-2,5) with a 600 ohm load. This step must be
completed for all parts of the alignment to ensure proper
level setting (Table 4).
1. Line In
• Set Line Input digital potentiometer (Pot) LI
to 0.
Channel Guard (GC)
• If the station is not programmed for CG, set
CG Pot to 0.
For a station programmed with CG encode follow
these steps:
• Execute a REMOTE PTT on the System
Module by flipping the REM PTT switch
on the front panel.
• Adjust the CG Pot as needed (Table 5).

that will be present on the line and must be
10 dB higher than average voice audio level.

below the "maximum system audio level"
even if your actual secur-it tone and function
tone are at the same level.)
Execute a REMOTE PTT on the System
Module by flipping the REM PTT switch on
the front panel.
Adjust the DSP Line In DLI Pot for 60% of
maximum system deviation if operating with
compression. (Table 9).
6.
Line Out
• If not a remote station, set the Line Out LO
Pot to 0.
• If the station is a remote station, apply an
"on Channel" RF signal modulated with a 1
kHz tone at 60% of system deviation to the
receiver. (60% of system deviation is
usually 3 kHz.)
• Adjust the Line Out LO Pot for the desired
output level as measured across 600 ohms.
The line out level must never rise above 7
dBm, as measured across 600 ohms.
• Re-enable Channel Guard decode.
7.
DSP cancellation
• If the station is a 4 wire station, set the DSP
Line Cancellation DC Pot to 0. If the station
is 2 wire, do the following:
Table 9 - Deviation For Setting Line In Pot With
Compression
•
Apply a RF signal to the receiver modulated
by a 1000 Hz tone at 60% of rated system
deviation and monitor the remote’s Line
Out. The level of the Line Out should be
between +7 dBm and -19 dBm.
•
Put the System module on an extender card
and meter TP1 on the DSP board. On
stations with Group 6 or later T/R shelf, the
TPI signal can be observed at J5-28A on the
backplane. An oscilloscope may be more
helpful than an analog meter. Adjust the
DSP Cancellation DC Pot for a null at TP1.

8).
If compression is desired, adjust the DLI Pot
for 60% of maximum system deviation
(Table 8).
Increase the audio input level to the
maximum system audio level. (This level is
the secur-it level, and is usually 0 dBm
across 600 ohms, or 775 mVrms. This level
must be 10 dB higher than the average voice
audio level.)
Adjust the Compressor Threshold CT pot for
desired compression deviation level (Table
10).

Tone Remote timing
You must have PC Programmer for base stations,
version 9.0 or later, to affect the timing of Tone
Remote Decoding.
If you have two wire tone remote, do the
following:
• In the timing screen of the option screen,
ENABLE Timed Tone Remote. The
default values of 100ms and 150ms will
appear for Secur-it minimum time and
Secur-it maximum time. Change these
values as your system requires.

AUDIO ROUTING AND
ADJUSTMENTS
Once the T/R Shelf is installed and programmed
properly, audio level adjustments may be made for proper
system operation. Level adjustments must be made with a
handset (LBI-38599). THERE ARE NO MANUAL
MECHANICAL ADJUSTMENTS IN THE T/R SHELF.
Integrated circuits (IC's) U35 and U36 on the System
Board are dual electronic potentiometers that are
controlled by the microprocessor. IC U15 on the DSP
Board is also a dual electronic potentiometer controlled
by the DSP.
TX AUDIO LEVEL ADJUSTMENT
U36-0 is used to set the transmitter deviation by
adjusting the TX AUDIO output level. Analog switch
26
U15 selects, which audio source is routed to the
transmitter. Possible sources are LOCAL MIC, REPEAT
AUDIO, DSP LINE/TX AUDIO, DSP TX AUDIO,
EXTERNAL High Speed Data, LINE IN AUDIO, OPEN
(used for Morse code ID), and GROUND (used for no
transmission. A battery alarm tone may also be summed
in with whichever source is selected with the exception of
GROUND.
Normally, LOCAL MIC, REPEAT AUDIO, DSP TX
AUDIO, LINE IN AUDIO, OPEN, or GROUND will be
selected. The gains in the circuitry are set such that 100
mVrms in the MIC HI or 1 Vrms (3 kHz deviation) in on
VOL/SQ HI (REPEAT AUDIO) will produce the same
out-put level on TX AUDIO HI. The gains for Morse
code ID and battery alarm are also designed to provide the
proper levels without adjustments. The TX AUDIO HI
output level should be adjusted with a 100 mVrms, 1 kHz
signal in on MIC HI or a 1 Vrms, 1 kHz signal in on
VOL/SQ HI.

REMOTE CONTROLLER TO STATION
CONTROL PANEL ADJUSTMENTS
Although audio levels should be considered on a
system basis, it is appropriate to set the levels of the
remote controller and the control station panel by
themselves with reference to the levels required by the
transmission path and then connect the controller(s) and
station to the path. The transmission path, if it is more
than just a simple twisted pair, is usually set up with a
"test tone". The "average voice" level is defined as being
a certain number of decibels below the test tone. The test
tone is normally the maximum level that can be sent
through the path without clipping or being regulated.
Although there is no definite agreement on the difference
between the test tone and average voice levels, 10 dB is
an appropriate level.
In order to align the RCN 1000 Remote Controller
and T/R Shelf properly, it will be necessary to have some
information on the transmission path. This will help to
determine the levels at each end required by the system.
Specifications needed include:
1. Loss at 1 kHz
2.
Test tone or maximum level
3.
Average voice level (if defined)
4.
Loss at 2175 Hz (if tone remote)
The DSP Board performs tone detection in a tone
remote installation. The "Secur-it" tone Decoder on this
board has a dynamic range of approximately 9 dB. The
system must be set up such that the "Secur-it" tones from
all remotes in the system arrive at the T/R Shelf within
this 9 dB window.
LINE OUT LEVEL ADJUSTMENT
U36-1 is used to set the line out level. Analog switch
U14 selects which audio source is routed to the line.
Possible sources are LOCAL MIC, VOL/SQ, auxiliary
receiver audio, auxiliary receiver audio summed with
VOL/SQ (simultaneous monitor), DSP LINE/TX
AUDIO, MODEM LINE data, OPEN (used for battery
alarm), GROUND (used for no transmission, and LINE
IN audio (used for four wire loop around). A battery
alarm tone and/or VG ALERT tone may also be summed
in with whichever source is selected with the exception of
GROUND. Typically LOCAL MIC, VOL/SQ, DSP
LINE/TX AUDIO, OPEN, GROUND, or LINE IN
AUDIO will be selected.
The gains in the circuitry are set such that 100
mVrms in on MIC HI or 1 Vrms (3 kHz deviation) in on
VOL/SQ HI (REPEAT AUDIO) will produce the same
line output level. The gains for VG ALERT tone and
30
battery alarm are also designed to provide the proper
levels without adjustments. The LINE output level should
be adjusted with a 100 mVrms, 1 kHz signal in on MIC
HI or a 1 Vrms, 1 kHz signal in on VOL/SQ HI.
LINE IN LEVEL ADJUSTMENT
Typically, the TX AUDIO and LINE OUT levels
should be adjusted prior to adjusting the LINE IN level.
DSP TX AUDIO and DSP LINE/TX AUDIO are
typically line audio or VOL/SQ HI audio that has been
processed by the DSP Board.
A DSP Board is always present, this DSP processed
line in audio will normally be selected by analog switches
U14 (DSP LINE/TX AUDIO to line out) and U15 (DSP
TX AUDIO to transmit audio) on the System Module
when line in audio is selected. The level for DSP TX
AUDIO and DSP LINE/TX AUDIO must be adjusted on
the DSP Board.
DSP LEVEL ADJUSTMENTS
The LINE IN level into the DSP must be adjusted
using U15-0 (DSP line cancellation level) and U15-1
(DSP line input level) located on the DSP Board. If twowire audio is used then both electronic pots must be
adjusted. If four-wire audio is used then only U15-1 needs
to be adjusted.
For two wire installations the DSP line cancellation
level pot (U15-0) is used to remove what the T/R Shelf is
transmitting on the line. While the T/R Shelf is
transmitting received audio down the line, the line
cancellation pot should be adjusted to minimize the signal
level at TP1 on the DSP Board. This leaves only what is
received from the remote. This signal is then level
adjusted using the DSP line input level adjust pot (U15-1)
and input into the DSP.
NOTE
System modules 19D902590G2, G3, & G4 must
have their cover removed to gain access to TP1 on
the DSP board. Modules G6 & G7 have TP1
extended to the board edge connector and may be
metered on the MASTR III backplane at J5, Pin
28A.
If four wire audio is used the DSP line cancellation
pot must be set to zero.
The DSP also performs a compressor function on its
line input. The threshold for this compressor must be
adjusted as well. The line level should be adjusted on the
DSP Board prior to setting the compressor threshold.
