Consolette Installation Guidelines
RF Operational Characteristics
Your ASTRO® Spectra® Consolette and ASTRO Spectra Plus Consolette contain a digital mobile wireless two-way
radio. When the Consolette is ON, it receives and transmits radio frequency (RF) energy.

Product Safety and RF Exposure Compliance

!
Caution

Before using this product, read the operating instructions
for safe usage contained in the Product Safety and RF
Exposure booklet enclosed with your radio (Motorola
Publication part number 6881095C99).

Operational Cautions
•

Because of danger of introducing additional hazards, do not install substitute parts or perform any unauthorized
modifications of equipment.

•

DO NOT operate the transmitter of any Consolette unless all RF connectors are secure and all connectors are
properly terminated.

•

All equipment must be properly grounded in accordance with Motorola Standards and Guideline for
Communications Sites “R56” 68P81089E50 and specified installation instructions for safe operation.

•

Slots and openings in the Consolette housing are provided for ventilation. To ensure reliable operation of the
product and to protect if from overheating, these slots and openings must not be blocked or covered.

•

Only an authorized technician familiar with the Consolette should service equipment.

Lightning and Surge Suppression
General
The installation of Transient Voltage Surge Suppression (TVSS) devices is a requirement for all communication sites
and is essential for all facilities where communication-related electronics and electrical equipment are in use. Surges
and transient power anomalies are potentially destructive electrical disturbances, the most damaging being overvoltage occurrences and short duration over-voltage events. Sometimes referred to as “spikes,” high-energy
transient power anomalies can arise from inductive load switching of other events within the power system or
capacitive and inductive coupling from environmental events, such as nearby lightning activity. Environmental and
inductive power anomalies are wideband occurrences with a frequency range from close to DC to well into the RF
high frequency spectrum. It is critical that each point-of-entry (AC, telephone, LAN, signal/control, and RF) into the
equipment area be protected against these anomalies. This protection is essential to reduce the risk of personal
injury, physical equipment damage, and loss of operations (equipment downtime).

Recommendations
To protect your equipment from lightning and surge damage, do the following:
•

Install these TVSS devices as described in Chapter 9, “Transient Voltage Surge Suppression,” of the Motorola
Standards and Guideline for Communications Sites “R56” 68P81089E50 manual.

•

Ground all RF transmission lines from the antenna structure to the shelter or building as described in Chapter 6,
“External Grounding,” of the Motorola Standards and Guideline for Communications Sites “R56” 68P81089E50
manual. Upon entering the building, all RF transmission lines shall route through a coaxial RF-type TVSS (or
Surge Protection Device).

Consolette Installation Guidelines

Safe Handling of CMOS Integrated-Circuit Devices
Introduction
This section will aid you in troubleshooting a malfunctioning Consolette. It is intended to be detailed enough to
localize the malfunctioning circuit and isolate the defective component.

!
Caution

Before using this product, read the operating instructions
for safe usage contained in the Product Safety and RF
Exposure booklet enclosed with your radio (Motorola
Publication part number 6881095C99).

Handling Precautions
Complementary metal-oxide semiconductor (CMOS) devices and other high-technology devices are used in the
Consolette. While the attributes of these devices are many, their characteristics make them susceptible to damage
by electrostatic discharge (ESD) or high-voltage charges.
Damage can be latent, resulting in failures occurring weeks or months later. Therefore, special precautions must be
taken to prevent device damage during disassembly, troubleshooting, and repair. Handling precautions are
mandatory for this radio and are especially important in low humidity conditions. DO NOT attempt to disassemble
the radio without observing the following handling precautions.
1. Eliminate static generators (plastics, Styrofoam, etc.) in the work area.
2. Remove nylon or double-knit polyester jackets, roll up long sleeves, and remove or tie back loose hanging
neckties.
3. Store and transport all static-sensitive devices in ESD-protective containers.
4. Disconnect all power from the unit before ESD-sensitive components are removed or inserted unless otherwise
noted.
5. Use a static-safeguarded workstation, which can be accomplished through the use of an antistatic kit (Motorola
part number 01-80386A82). This kit includes a wrist strap, two ground cords, a static-control table mat and a
static-control floor mat.
6. Always wear a conductive wrist strap when servicing this equipment. The Motorola part number for a
replacement wrist strap that connects to the table mat is 42-80385A59.

Parts Replacement and Substitution
Special care should be taken to ensure that a suspected component is actually the one at fault. This special care
will eliminate unnecessary unsoldering and removal of parts, which could damage or weaken other components or
the printed circuit board (PCB) itself.
When damaged parts are replaced, identical parts should be used. If the identical replacement component is not
locally available, check the parts list for the proper Motorola part number and order the component from the Radio
Products Services Division.

Introduction

General

The information presented in this manual describes the installation, operation,
and maintenance of the ASTRO™ Spectra®/Spectra Plus Consolette. Refer to
the front of this manual for the model/option chart and performance
specifications. For additional information about the ASTRO Spectra/Spectra
Plus radio, refer to the appropriate ASTRO Spectra/Spectra Plus radio user’s
guide and service manual.
The ASTRO Spectra/Spectra Plus Consolette incorporates functional design in
a modern, lightweight plastic housing. This housing was designed using
“design-for-assembly” principles to minimize fasteners, part count, and
assembly time, while improving versatility, assembly ease, and quality.
The Consolette consists of a base plate, onto which the entire Consolette is
assembled. Subassemblies, which “snap-fit” into this base, include the fan,
power supply, audio interface or optional tone remote control board, ASTRO
Spectra/Spectra Plus radio, RF connector, and front panel assembly. The
ASTRO Spectra/Spectra Plus radio, fan, and power supply also have screws
that are used to secure them.
The front panel assembly consists of the ASTRO Spectra/Spectra Plus control
head assembly, speaker, power-on LED, optional VU meter/clock, and optional
keyloading connector. In addition, all internal cabling for the station is
completely connectorized. To complete the assembly, the top cover snaps into
the base plate. See “Diagrams and Parts Lists” on page 51 for the Consolette
exploded view and detailed cable connectorization information.
The ASTRO Spectra/Spectra Plus Consolette allows conventional or trunked
operation, analog or digital operation, SECURENET™ operation, local control,
tone remote control, Digital Remote Control, and a variety of other options. The
Microsoft Windows-based Customer Programming Software (CPS) allows for
field programming for such items as channel frequencies, PL/DPL, etc.
The ASTRO Spectra/Spectra Plus Consolette supports all ASTRO mobile
features except Siren, Vehicular Repeater System, and those requiring the
addition of a direct-entry keyboard (DEK). Refer to the applicable ASTRO
Spectra/Spectra Plus service manual for additional information about ASTRO
features.
NOTE:

6881086C22-B

While SCAN can be enabled on the ASTRO Spectra/Spectra
Plus Consolette, it is advised that this feature not be used in
conjunction with the Tone Remote Control option. This
feature does not indicate to the remote user which channel
the ASTRO transceiver may have scanned to, and thus
might cause confusion.

control head (W7 models) or at the remote control head (W9 models). If the
TRC option L146 is ordered in combination with the G114 option, then the ID
will be made available to the console. The PTT-ID option is not automatically
enabled in the ASTRO Spectra/Spectra Plus Consolette. To enable the G114
option, the ID Display field in the ASTRO Spectra/Spectra Plus Consolette
codeplug will need to be enabled using ASTRO CPS. The ID Display field can
be found in the Radio Configuration –> Display & Menu section of the ASTRO
Spectra/Spectra Plus Consolette codeplug.
NOTE:

Enhanced Stat-Alert
Repeater Access, G101

2

The ASTRO Spectra/Spectra Plus Consolette uses an
ASTRO Spectra/Spectra Plus Mobile subscriber radio as its
transceiver. Therefore, the ASTRO Spectra/Spectra Plus
Consolette will NOT decode an Emergency Alarm generated
by field subscriber units, and it will NOT display the
Emergency Alarm ID locally or at a console station. This
signal is typically generated by the subscriber radio by
pushing the orange alarm button.

This option allows the user to access a specific repeater for voice and data
transmission. This option is NOT available on the ASTRO Spectra Plus
Consolette.

Installation

Planning the
Installation

Since a good installation is important to obtain optimal performance of the
Consolette, carefully plan the installation before the actual work is started.
Location of the Consolette in relation to power, control lines, and antenna, as
well as convenience and access for servicing, should be considered.
NOTE:

The RF transmission line should be kept as short as possible
to minimize line losses; however, the antenna should not be
placed so close as to cause interference with the Consolette.
See “Lightning and Surge Suppression” on page ix of this
manual for additional antenna, RF transmission line, and
control line installation considerations.

Read the entire procedure and the suggestions offered to help plan the
installation. Make sure all necessary equipment and facilities are available
during installation.
The ASTRO Spectra/Spectra Plus Consolette is not recommended for dense
site applications (that is, dense metropolitan areas or “antenna farms”).

Ventilation

The Consolette is designed for wall mount or horizontal flat plane installation
with forced convection cooling on both mountings. For proper cooling, the
Consolette must be kept free of obstructions at its back and sides for at least
4 inches (100 mm), so as not to restrict airflow.
NOTE:

Make certain that the air temperature around the unit does
not exceed the recommended operating temperature range
of –20°C to 50°C.

Station Mounting
Procedures

Refer to the specifications section in the front of this manual for unit
dimensions.

The Consolette may be placed on any solid, flat surface with easy access to
the power source and RF transmission line. Keep in mind the ventilation
requirements as previously described in “Ventilation” on page 5.

Wall Mounting

Ensure that the selected mounting surface is strong enough to support the
Consolette weight of 16 lbs. Mark the location of the four mounting screws. See
Figure 1 on page 6. Use screws suitable for the wall material. The maximum
diameter of the screw and screw head should be 0.25 inches (6.5 mm) and
0.43 inches (11 mm), respectively. Allow the bottom surface of the screw head
to protrude 0.3 inches (7.5 mm) from the wall surface. Hold the station with the

Antenna
Connections

The antenna and transmission lines are not part of the Consolette; therefore,
antenna installation instructions are not included in this section. Refer to the
instructions shipped with the antenna for applicable information.
In its primary application, the Consolette is used for communication with mobile
radios. Therefore, an omni-directional antenna is recommended. However, if
the Consolette is located at the outer perimeter of a communications area, or
if it is to be used for communication with a fixed station, an antenna with
specific directional characteristics may be preferred. Local government
agencies may also dictate the type of antenna to be used.
The coaxial antenna cable connects to an N-type coaxial connector located on
the rear panel of the station. See Figure 2.

Installation: Power and Ground Connection

Power and Ground
Connection
General

All Consolettes should have a separate AC power circuit with proper current
and voltage for Consolette operation. Refer to the specifications section in the
front of this manual for AC requirements of each model. The power lines should
be installed in accordance with local electrical codes. A substantial earth
ground must be provided in a straight line close to the ground terminal provided
on the Consolette. DO NOT consider an electrical output box as a substantial
earth ground. See “Lightning and Surge Suppression” on page ix for additional
grounding recommendations.

!
WARNING

Even if a three-wire grounding AC power source is
available, the radio equipment must be grounded
separately to prevent electrical shock hazards and
provide lightning protection.

The AC power line leading to the selected site for the Consolette may be
installed prior to installation of the Consolette itself.

AC Power Input

!
WARNING

The Consolette is shipped standard from the
factory for operation from a 115 VAC power
source. For 230 VAC operation, remove the
Consolette top cover (see “Disassembly and
Reassembly” on page 38) and slide the AC power
selector switch, located on the Consolette power
supply, to the 230 VAC position. Install the
appropriate AC power connector on the end of the
115 VAC power cord provided with the Consolette.

Installation: DIP Switch and Jumper Settings

1. Install the Consolette as described in “Station Mounting Procedures” on
page 5.
2. Connect the female plug of the AC line cord to the AC input power
connector on the rear panel of the station. See Figure 2 on page 6.
3. Connect the ground terminal on the Consolette in as straight a line as
possible to a substantial earth ground located as close as possible to the
Consolette ground terminal.
4. Make certain the AC power source is of the proper current and voltage
rating for the Consolette. Refer to the specifications section in the front of
this manual for the AC requirement of each model. Then connect the male
plug of the AC line cord to the AC power source.
NOTE:

DC Input Power
(Optional)

The ON/OFF power button located on the ASTRO control
head is disabled before shipment; therefore, the Consolette
is immediately operational when its power cord is plugged
into a live AC outlet. To enable the ON/OFF power button on
the ASTRO control head, refer to the information in “DIP
Switch and Jumper Settings” on page 8. Please note that the
ON/OFF power button on the control head controls the power
to the control head only. For Consolettes containing the
Digital Remote Control feature, W9 models, no control head
is present and the Consolette will always be immediately
operational when its power cord is plugged into a live AC
outlet.

Connection of DC input power to the Consolette is offered as an option. The
battery should be connected to the DC connector (DC IN) on the rear panel of
the Consolette. See Figure 2 on page 6. Note that the top and bottom pins of
DC IN are the negative and positive terminals, respectively.

!
Caution

DIP Switch and
Jumper Settings

The DIP switches and jumpers are used to provide various operating
configurations to the Consolette. The Audio Interface board has a DIP switch
package and three jumpers. The optional Tone Remote Control board has two
DIP switch packages, two jumpers, and two plugs. Refer to the tables below
for detailed descriptions of switch and jumper settings for each board.
NOTE:

8

To prevent damage to the Consolette, be sure to use
a battery that is connected only to the Consolette.
Disconnect both battery terminals from the
Consolette when connecting the battery to any other
equipment, including a battery charger. Be sure to
observe proper polarity when making the DC power
connections.

0Ω chip resistors are used for some jumpers. A low-power
soldering iron must be used to install and remove them.

Theory of Operation

Introduction

This section explains the general operation of the ASTRO Spectra/Spectra
Plus Consolette. For more detailed information about the ASTRO transceiver,
refer to the applicable ASTRO Spectra/Spectra Plus operator’s manual or
service manual.
Provisions have been made for the connection of voice recorders to the
ASTRO Spectra/Spectra Plus Consolette.

General

The ASTRO Spectra/Spectra Plus Consolette consists of three major building
blocks: the ASTRO transceiver, the Audio Interface or optional Tone Remote
Control board, and the power supply. The Audio Interface board is standard for
the Consolette. The Tone Remote Control board replaces the Audio Interface
board when the L146 option is added. All other blocks contained within the
Consolette are served by the three major building blocks shown in bold (see
Figure 5).

Each major building block has its own unique function:

6881086C22-B

•

Modulation, demodulation, and all other RF signal processing are
performed by the ASTRO transceiver.

•

All baseband signals being routed to and from the radio pass through the
Audio Interface board or optional Tone Remote Control board. The board
provides an interface for the ASTRO control head, speaker, accessory
connectors, and other options.

19

Theory of Operation: General

•

The power supply converts AC power into DC power for use by the radio’s
transceiver and the Audio Interface board or optional Tone Remote Control
board.

The ASTRO Spectra/Spectra Plus control head and speaker are present in all
W7 models. W9 Digital Remote Control models do not have a control head or
speaker. Refer to the appropriate ASTRO Spectra/Spectra Plus radio user’s
guide for information regarding the operation of the control head.
The accessory connectors (see Figure 2 on page 6) are used to connect
external equipment to the Consolette. Accessory Connector 3 (top) is currently
used for tape recorder audio out. Tone remote desksets or digital remote
desksets should use Accessory Connector 2 (bottom). Accessory Connector 1
(RJ45) is used to connect to a Gold Series Elite Console via the ACIM.

!
Caution

If any external equipment is inadvertently connected
to the wrong accessory connector, damage to the
equipment may result.

The optional VU meter/clock provides a transmit audio level indicator and a
digital clock display. Power is provided to the VU meter/clock as soon as the
Consolette is plugged into a live AC outlet.
A fan is provided with every Consolette. It circulates the air inside the
Consolette to keep the internal ambient temperature at an acceptable level. It
is important for the fan to be operating at all times to maintain proper
Consolette operation. In addition, it is important to leave the top cover in place
to maintain proper thermal conditions inside the Consolette.
The location of the control head, Power On LED, VU meter/clock, and speaker
are indicated on the front panel of the station shown in Figure 6.

Theory of Operation: Audio Interface Board

Audio Interface
Board
General Description

The TRN7391C Audio Interface board (AIB) serves as the central interface for
all internal and external components of the ASTRO Spectra/Spectra Plus
Consolette. All signals are routed through the AIB where processing may
occur. Most audio paths incorporate some processing, while most control and
data signals are passed unaltered.
Multiple transmit and receive audio paths provide for numerous configurations
of the ASTRO Spectra/Spectra Plus Consolette. All audio signals passing
through the audio interface board are baseband signals in the range of
300-3000 Hz.
Most data and control signals are provided by 0-5V protected CMOS logic
circuitry. PTT* and MONITOR* are provided for external control of transmit and
receive functions. The ASTRO radio Vehicle Interface Ports (VIPS) are also
available at Accessory Connector 2 (W7 models only).

Detailed Description
Receive Audio Paths

Two sources from the ASTRO radio are used for receive audio. Detect audio
(DET_AUD) is located on J1 pin 17, and filtered audio (FILT_AUD) is located
on J1 pins 11 and 36. Both DET_AUD and FILT_AUD are at a fixed level
(approx. 300 mVrms); however, DET_AUD has a DC voltage level associated
with it, while FILT_AUD has no DC voltage. FILT_AUD is also present at
Accessory Connector 2 pin 4 and Accessory Connector 3 pin 4.
Detect audio (DET_AUD) passes to the Audio Interface board via J1 pin 17 at
a level of 300 mVrms, relative to a 1.0 kHz tone at 60% FSD. It is then amplified
by U102 pins 8, 9, and 10 and the level set by potentiometer R111. The level
should be set to attain 1.0 Vrms between RX+ and RX– (Accessory Connector
2 pins 1 and 16, respectively). The audio then passes through an audio
shaping filter (U102 pins 12, 13, and 14), which has unity gain for frequencies
below 3000 Hz. The output of the audio shaping filter (U102 pin 14) is split into
opposing phases by U102 pins 1, 2, 3, 5, 6, and 7 to provide a balanced output.
Q103 and Q104 provide a final amplification stage. The impedance between
RX+ and RX– can be set to 600Ω or 900Ω using S101-4 and 5. See Table 1
on page 9.
When the radio is in an idle state, the DET_AUD line of the ASTRO Digital
transceiver is muted using the U107 op-amp circuit in combination with
multiplexor U106. U107 compares the voltage level of the SPKR_HI line (U107
pin 3) to a fixed DC voltage level of 4V (U107 pin 2). When the mobile radio
routes received audio to the speaker, the SPKR_HI line measures
approximately 6 Vdc. This causes the output of U107 to activate transistor
Q101 connected to control input A of the two-input multiplexor (U106 pin 11).
When Q101 is active, U106 allows DET_AUD to be passed to the receive
audio circuitry. When Q101 is inactive, the receive audio path is muted.
Receive audio is also routed from U106 gate 1 to buffer amplifier U101 opamp 4 (MOB_RX). The output of this buffer drives the TAPE_OUT line at
approximately 190 mVrms, which is used for external recording purposes.

Theory of Operation: Audio Interface Board

Speaker audio is available at Accessory Connector 2, pins 14 and 15
(REMOTE_RX+ and REMOTE_RX–, respectively) for use with Digital Remote
Control models. Speaker audio level is factory set but can be adjusted using
Customer Programming Software. An array of resistors capable of dissipating
10 watts provides a 16Ω impedance for the desksets. To enable this audio
output, S101-7 must be ON.

Caution

Transmit Audio Paths

REMOTE_RX– (SPKR_LO) and REMOTE_RX+
(SPKR_HI) should never be grounded. If they are
grounded, this will damage the radio.

There are three main paths for transmit audio. All of these paths pass through
transmit audio summing amplifiers (U101 pins 8, 9, and 10). The output of the
summing amplifier (U101 pin 8) following AC-coupling capacitor C101 is fed
into the ASTRO radio microphone input at J1 pin 23 and J1 pin 48. The level
of this signal should be 90 mVrms relative to a 1.0 kHz tone at 60% FSD.
Local microphone audio passes through the control head to J2 pin 30. The
microphone audio is biased and passed through the summing amplifier with
unity gain. This path has an impedance of 600Ω.
A differential transmit path is available at Accessory Connector 2 pins 3 and 11
(TX+ and TX–, respectively) with an impedance of 1.0kΩ. This signal is
combined at U101 pins 2 and 3 into a linear signal at U101 pin 1 and then
routed through the transmit audio summing amplifier with a gain of +6 dB.
A linear transmit audio path is provided at Accessory Connector 2 pin 17
(TX_AUD). This transmit path has an impedance of 600Ω and unity gain
through the transmit summing amplifier.
Transmit audio taken from the MIC_HI line is routed to the tape recorder output
based on the jumper position at header J14. TX audio is routed to the tape
recorder output at approximately 90 mVrms when the jumper is in the A-B
position. If the jumper is moved to the B-C position, TX audio is not routed to
the tape recorder output. (The TX and RX audio measurements were made
relative to a 1 kHz tone at 60% FSD.)
Transmit audio is routed to the VU meter/clock (option L114) with a gain of
+14dB.

Control and Data Paths

The Audio Interface board is transparent to all control and data lines except the
data bus lines, MONITOR*, EMER (Emergency), and SPKR_UNMUTE. The
amount of gain developed by U105 is determined by the current requirements
of the remote desksets. Each op-amp on the BUS+, BUS-, and BUSY lines
compares the voltage drop between the + and – inputs. The resulting amplified
signal is further amplified by the transistor following each op-amp.
MONITOR* is presented to the radio with S101-6 OFF. See Table 1 on page 9.
The monitor function is available at the control head.
EMER (Emergency) is available at Accessory Connector 3 pin 13. When
triggered, the radio will broadcast an emergency signal (refer to the ASTRO

22

6881086C22-B

Theory of Operation: Tone Remote Control Board

Spectra/Spectra Plus radio user’s guide). S101-3 determines the method in
which the emergency is triggered.
SPKR_UNMUTE is available at Accessory Connector 2 pin 25 as an output to
provide an indication to accessories when the radio is receiving valid audio and
the speaker is unmuted. This signal is configurable for either active-high or
active-low operation using jumper J15. See Table 2 on page 9. When
configured for active-high, the emitter of Q101 is used to determine the state
of the speaker. (If the voltage of the emitter of Q101 is high, the speaker is
unmuted; if the voltage here is low, the speaker is muted.) Similarly, if activelow is selected, the collector of Q102 is used to determine the state of the
speaker. (If the voltage at the collector of Q102 is high, the speaker is muted;
if the voltage here is low, the speaker is unmuted.) Typically, this signal is
known as COR (Carrier-Operated Relay).

Tone Remote Control
Board

General Description

NOTE:

For the ASTRO Spectra/Spectra Plus Consolette to work
properly with the Tone Remote Control (TRC) option, several
codeplug parameters must be properly set using the ASTRO
mobile CPS. The TRC option must be enabled, and “HUB
defeats PL” must be selected. For instructions on setting
these parameters, see the ASTRO mobile CPS manual.

Tone Remote Control (TRC) allows control of a Consolette from a remote
location using a pair of wires (wireline) which need not have DC continuity.
Control is accomplished using a tone remote control console that sends a
sequence of control tones that are interpreted by the Consolette. A Consolette
function normally corresponds to a function tone (FT) of a predefined
frequency. All function tones must be preceded by a high-level guard tone
(HLGT—usually 2175 Hz), which alerts the Consolette for a sequence of one
or more function tones. On two-wire operation, receiver audio is muted when
HLGT is detected, so there will be no interfering audio signals on the wireline
when the function tones are being received. Upon receipt of the function
tone(s), the appropriate functions (are) executed by the Consolette. An
example might be the monitor function, which disables receiver PL; the monitor
function tone frequency is usually designated 2050 Hz. See Table 12 on
page 24 for function tone descriptions.
Receiver audio is gated through the radio and passed through a guard tone
notch filter on the TRC board. This processed audio is then filtered and applied
to the phone line. Transmit audio passes through a sample-and-hold AGC
circuit, a guard tone notch filter, and then to the radio to transmit. Audio coming
from the wireline is also passed through a bandpass filter that is centered at
the guard tone frequency. This audio is then routed to the microprocessor
(U123) to be decoded.
Figure 8 illustrates the sequence of tones involved in a line push-to-talk (LPTT)
function. In such a case, the function tone must be defined as a transmit
function on a certain mode (that is, 1950 Hz is usually defined as the function
tone for keying on mode 1). If an LPTT function tone is sent, the remote control
console follows the function tone with a continuous low-level guard tone
(LLGT), which is at the same frequency as the HLGT, but at an amplitude 30 dB
lower. LLGT is a pilot tone that is present, along with the transmitted audio, for
the duration of the transmission. At the end of the transmission, the Consolette
dekeys after the LLGT is no longer detected.

During an LPTT function, the LLGT is removed from the transmitted audio path
by a notch filter on the TRC board. This notch filter is tuned to the guard tone
frequency (2175 Hz).
When not in the LPTT mode, the TRC board accepts receiver audio from the
ASTRO radio, passes it through a notch filter (tuned to guard tone), and then
through a line driver for transmission down the wireline to the remote console.
The receive notch filter prevents false HLGT detection due to possible receiver
audio components near the guard tone frequency (since on a two-wire board,
receiver audio output and transmit audio/tone inputs are tied together at the
wireline).

Detailed Description
Control Point Monitor

The ASTRO Spectra/Spectra Plus Consolette with the TRC option (L146)
supports Control Point Monitor as defined by the FCC. The local Consolette
speaker will unmute for remote audio that is being passed from the remote
device to the Consolette to be transmitted. When the local microphone is
keyed, the local speaker will be muted to voice audio. In addition, audio from
the local microphone that is to be transmitted by the Consolette is routed, via
the wireline interface, to the remote device. (This is not needed for FCC
Control Point Monitor and can be disabled by S100-2.)
When the ASTRO Spectra/Spectra Plus Consolette with the TRC option is
being used by both a local and a remote user at the same time, situations arise
in which one user has priority over the other. The following cases describe the
effect of dual interaction:

Receive Audio Path

•

If the remote user performs a push-to-talk (PTT) while the local user is
already keyed, the remote user’s audio will be transmitted with the
encryption state that the local user has selected. This is only the case if
the remote user requested a PTT on the same channel that was selected
by the local user. If the remote user requested a PTT on a different
channel than what was selected by the local user, the Consolette will
dekey and a “bad” alert tone will be heard by both users until both PTTs
are released.

•

If the remote user attempts to change channels while the local user is
keyed, the Consolette will dekey and a “bad” alert tone will be heard until
the local user releases the PTT.

•

All attempts by the remote user to change the state of encryption are
ignored if the local user is already keyed.

•

If the local user performs a PTT while the remote user is already keyed,
the local user’s audio will be transmitted on the channel that the remote
user has selected with the encryption state that the remote user has
selected.

•

If the local user attempts to either change channels or the state of
encryption while the remote user is keyed, the Consolette will dekey and a
“bad” alert tone will be heard until the remote user releases the PTT.

Audio from the receiver, as well as the various tones produced from the mobile
(that is, keyfail tones and button-press “beeps”), are gated through the ASTRO
transceiver and sent to the TRC board via a ribbon cable that plugs into J1 pin
42 (DET_AUD). Audio coming from the transceiver should measure
approximately 300 mVrms.
DET_AUD from the ASTRO transceiver is always passed through U116 gate 2
(S100-1 is always OFF for the Consolette). Audio at U116 pin 14 should
measure approximately 90 Vrms. Receive audio then passes through the
muting gate (U116 gate 1), controlled by RX_MUTE. Receive audio muting is
controlled by the microprocessor (U123 pin 36), which toggles the RX_MUTE
output line. When HLGT is detected or an LPTT is in progress, the receiver
audio will be muted. This gate is also muted for a local PTT in order to block
ASTRO noise at the DET_AUD line from entering the wireline.
The audio is passed through buffer amplifier U105 op amp 3 and then notched
at the guard tone frequency (2175 Hz) by hybrid HY2 filter 1. This hybrid

6881086C22-B

25

Theory of Operation: Tone Remote Control Board

contains an MF10 dual switched capacitor filter and a dual op-amp for
summing purposes. The notch filter is formed by summing together the highpass and low-pass outputs of the filter IC. The MF10s on both HY1 and HY2
require a high-frequency clock input that is derived from a divider circuit (U127
and U129) and the MPU “E” clock. The output of the clock divider circuit
(FILTER CLK) is a 110.4 kHz square wave that is used by the MF10s to create
the filters. The purpose of the notch filter is to notch out the guard tone
frequency area of the voice spectrum prior to transmission across the wireline.
The receive notch filter has a gain of 0 dB at 1 kHz. At the 2175 Hz notch
frequency the response is -35 dB, relative to 1 kHz. To allow the slight drifting
of the guard tone frequency due to wireline translation, the filter must
guarantee 30 dB of attenuation at ±5 Hz from the center frequency. The filter
has a “Q” of 3.8 in order to remove all voice components in the guard tone
frequency range before reaching the wireline. Without this protection, false
guard tone detects by the TRC board would be inevitable, since the audio
leaving the TRC board is up to 20 dB higher than that arriving to make up for
wireline attenuation.
The output of the notch filter passes through another muting gate (U114 gate
2). This audio path is always closed when the Consolette is receiving. Local
microphone audio and trunking tones also share this audio path to the console.
During local PTT this gate can be used to mute local audio on the receive path
(see “Transmit Audio Path” on page 26).
Receive audio is also routed from U116 gate 1 to buffer amplifier U106 op amp
4 (MOB_RX). The output of this buffer drives the TAPE OUT line, which is used
for external recording purposes.
The line-adjust circuit (U111 op amp 3 and R545) allows the notched audio
level to be adjusted via R545. By varying R545, you can adjust the audio level
to the line. This allows you to compensate for line losses to obtain the desired
audio levels. The adjusted audio is then sent through an audio-shaping filter
(U111 op amp 4). This filter is a unity-gain, low-pass filter with a corner
frequency of 3 kHz.
The output of the line audio-shaping filter is split into opposing phases in the
line driver circuit (U111 op amps 1 and 2, Q114 and Q115), where the receiver
audio is applied to the line transformer and the phone line. With two-wire
selected, the line driver audio is also applied to the input of the transmit audio/
tones detection path through T100-6. A portion of the line driver audio is also
fed into the input amplifier of the transmit audio/tone detection path, via U111
op amp 2 and S101-7,8; this audio is approximately 180° out of phase with the
received audio at T100. This is done in order to, at least partially, cancel the
receive audio so that a tone from a control console may be more easily
detected in the presence of receiver audio. With four-wire selected, this
cancellation is not necessary and S101-7 should be open and S101-8 should
be closed.

Transmit Audio Path

26

Wireline audio originating from a console to be transmitted over the air is
applied to the wireline interface network. The wireline interface network
consists of T100 (two-wire operation), T1610 (four-wire operation), U110, and
other discrete components. The purpose of this circuitry is to match the
impedance of the TRC board to that of the wireline (T100, T1610, S101), block
any DC components between the TRC board and the wireline (C502, C501),
and provide protection from surges on the line (E1, E2).

6881086C22-B

Theory of Operation: Tone Remote Control Board

The input from the phone line is applied to U112 op amp 1 pin 2, along with the
line driver audio-canceling voltage (described previously) via S101-7 and
S101-8. The gain of U112 op amp 1 is controlled by FET transistor Q113. The
lower the DC gate voltage on Q113, the higher the gain, since a more negative
gate voltage tends to turn off the FET, creating maximum feedback resistance
across pins 1 and 2 of U112 op amp 1. The AGC potentiometer (R529) sets the
maximum gain point of the AGC. Normally, the potentiometer setting allows
input signals as low as –35 dBm to achieve full deviation. After the AGC circuit,
the audio is amplified by a factor of 20 (U112 op amp 4) and is sent to the
transmit guard-tone notch filter (HY2 filter 2).
The transmit guard-tone notch filter is formed by summing the two outputs of
the hybrid in the same manner as the receive notch filter previously discussed.
This filter notches out the guard-tone frequency area of the voice spectrum
before sending the audio to the radio to be transmitted. The notch filter's high
“Q” of 5.8 ensures removal of the guard-tone frequency component without
affecting the adjacent voice energy in the audio signal being transmitted.
The filtered audio level is adjusted by potentiometer R569 to set the
transmitted deviation. The audio is routed through buffer amplifier U105 op
amp 4 and then (via TX_AUDIO) into amplifier U110 op amp 1, after which it is
sent to the ASTRO transceiver to be transmitted. The audio is also passed to
buffer amplifier U106 op amp 2. The output of this buffer drives the TAPE OUT
line, which is used for external recording purposes.
The filtered audio is also passed to amplifier U106 op amp 1, whose gain is set
by digital potentiometer U107. The audio is passed to the AUX_RX_AUD input
of the radio, where it is then output to the local speaker.
Audio tones associated with trunking operation are generated locally on the
TRC board. They originate from the microprocessor (U132 pin 38) and are
filtered by low-pass filter U106 op amp 3. The filtered tones are then sent to
buffer amplifier U105 op amp 3 to be sent down the wireline to the remote
speaker.
Local microphone audio (MIC_AUDIO) is passed to buffer amplifier U105 op
amp 2. It is then sent down the wireline allowing local transmit audio to be
monitored at the remote unit. If it is desired to prevent local audio (audio not
received by the radio) from being routed to the remote speaker via the wireline,
place S100-2 to the ON position. This will cause microprocessor U123 pin 35
(WL MUTE) to be asserted, opening the wireline path at U114 gate 2 for local
microphone audio, local trunking tones, and locally generated beeps. Local
microphone audio is also passed through buffer amplifier U105 op amp 1 to
TX_AUDIO to the transmitter

Tone Processing Section

Inputs to this section originate from TP1 (the output of U112 op amp 4) in the
wireline transmit audio path. When looking for guard tone (standby operation),
the audio is selected by U114 gate 1 to be routed through the guard tone
bandpass filter and then sent to the filter/limiter. After high-level guard tone
(HLGT) has been detected, U114 gate 1 is toggled to allow audio to bypass the
bandpass filter. This permits unfiltered audio to be decoded and allows for
proper identification of the function tones.
The limiter consists of a gain stage (U112 op amp 3), which also provides some
broadband filtering, followed by a limiter stage that converts the signal to a
square wave. The output of U112 op amp 2 drives transistor Q116. This
transistor provides an input to the microprocessor's Input Capture (U123

6881086C22-B

27

Theory of Operation: Tone Remote Control Board

pin 41). The input to this pin is a 0-5V peak-to-peak square wave. The
frequency of the square wave depends on the particular guard/function tone
being sent. The microprocessor determines which tone is being sent and then
takes the corresponding actions.

AGC Circuit Operation

The output of U112 op amp 4 feeds reference comparators (U117 op amps 2,
3, and 4) of the AGC circuit. If the peak voltage at the input exceeds the
threshold of U117 op amp 4 (+5.8V) in the positive direction, the output of U117
op amp 4 pulses high, causing current to pass through R510 and charge C506
via D1012. Similarly, if the peak minimum voltage at the input dips below the
threshold of U117 op amp 3 (+3.6V), U117 op amp 3 will allow a pulse of
current to pass through R509 to charge C506 via D1013. As C506 charges, the
DC voltage on the gate of Q113 rises. This rise in gate voltage on Q113 will
reduce the drain-source resistance and hence the gain of U112 op amp 1. This
in turn will reduce the output of the AGC circuit. This output is again used to
feed the comparators, and the process continues until the voltage is just equal
to the threshold of U117 op amp 4 minus the threshold of U117 op amp 3, or
2.2V peak-to-peak.
The “sample-and-hold” action of the AGC occurs when a new HLGT is
received. Upon detection of HLGT by the microprocessor (U123 pin 41), the
AGC_RESET* line (which has been low when no LPTT was present) and the
TONE detect line will go high (approximately 5V). This action will cause the
gain of Q113 to rapidly increase (C503 is placed parallel with the smaller C506,
reducing the gate voltage on Q113), and also turns Q110 off to allow a higher
gain in the U112 op amp 1 stage. This action will momentarily cause a rise in
the AC voltage level on TP1 above the usual compression point of 0 dBm.
During the time that the peak voltage on TP1 is more than 0.7V higher than the
1.1V peak (0 dBm) threshold, comparator U112 op amp 2 and Q116 are
actuated to provide faster than normal attack (gain reduction) time. In this
manner, the gain is always reset to maximum at the beginning of a new line
push-to-talk, and then is reduced as required until the HLGT is at 0 dBm (which
is the AGC compression point) as measured on TP1. This ensures full
deviation, regardless of the amplitude of any audio signal on the line just prior
to the line push-to-talk.
During an LPTT function, the Auto Level Control (ALC) action of the AGC
causes the gain to freeze for the duration of LLGT. This will preserve the natural
characteristics of the speech without producing any pumping effects.
In extreme cases where the audio signal received at the Consolette is
unusually low (due to very long lines or other attenuating factors), the AGC
action of the TRC board may be inhibited, yielding slightly more gain. Switch
S100-4, when set to the ON position, will disable the AGC circuitry. Absolute
gain and transmit deviation is then adjustable by potentiometers R529 and
R569, respectively. This option is NOT recommended because the Low-Level
Guard Tone (LLGT) may already be too low to be detected and thus the
Consolette will not transmit.

Power Distribution

28

A+ is routed to the TRC board from the power supply through J11. This
connection provides ignition sense to the control head and the mobile. When
S101-1 is in the ON position, A+ is immediately sourced from the power supply
to the SWB+ connections of the mobile, control head, and TRC board. When
S101-1 is in the OFF position, the user must enable power at the front of the
control head. SWB+ is then sourced from the control head to the mobile and to
the TRC board.

6881086C22-B

Theory of Operation: Tone Remote Control Board

On the TRC board, A+ is converted to regulated 9.6V through U100. From this
9.6V source, several comparator voltages are produced. SWB+ is routed to a
5V regulator (U132) on the TRC board, which provides regulated 5V to all of
the logic ICs.
One exception to the IC power distribution is the Serial I/O IC (U131). This IC
needs to be powered at all times, regardless of the state of S101-1. A+ is
routed to U131, as well as a continuous 5V source from the regulated 9.6V
source.

Input/Output Control
Definitions

AGC_INHIBIT*—This signal is generated by the microprocessor (U123)
through the latch (U124 pin 14). It is used to disable the AGC circuit of the TRC.
TONE_DETECT—This signal is generated by the microprocessor (U123)
through the latch (U124 pin 12). It is toggled from low(0V) to high(5V) when a
guard/function tone is successfully detected. This line provides a discharge
path between C503 and C506, which varies the gain of the AGC circuit.
LPTT*—This signal is generated by the microprocessor (U123) through the
latch (U124 pin 19). It is high during an LPTT to provide additional gain for
LLGT. This additional gain improves the accuracy of the tone decoding
process.
GT/FT*—This signal is generated by the microprocessor (U123) through the
latch (U124 pin 17). During the detection of guard tone, the bandpass filter is
switched into the path of the audio. This allows isolation of the 2175 Hz signal
and provides more accurate decoding. Once the guard tone has been
detected, the signal line goes low. This switches the bandpass filter out of the
path to allow the function tone(s) to pass to the limiter/decoder undisturbed.
RX_MUTE—This signal is generated by the microprocessor (U123 pin 36). It
is used to mute receiver audio (DET_AUD) when an HLGT has been detected
or an LPTT is in progress. DET_AUD is also muted during a local PTT to block
ASTRO noise from entering the wireline.
WL_MUTE—This signal is generated by the microprocessor (U123 pin 35). It
is used to mute the wireline during a remote PTT, and when S100-2 is in the
ON position (mute local audio and local trunking tones).
AGC_RESET*—This signal is generated by the microprocessor (U123)
through the latch (U124 pin 16). It is used to provide an additional discharge
path for C503 and C506 (changing the feedback path of U112A in the AGC
circuit). Upon detection of HLGT by the microprocessor, the AGC_RESET line
will go high. AGC_RESET will go low at the end of LPTT.
SPKR_UNMUTE—This signal is available at Accessory Connector 2 pin 25 as
an output to provide an indication to accessories when the radio is receiving
valid audio and the speaker is unmuted. This signal is configurable for either
active high or active low operation using Plug P102. See Table 6 on page 11.
When configured for active high, the emitter of Q117 is used to determine the
state of the speaker. (If the voltage at Q117's emitter is low, the speaker is
muted, and if the voltage here is high, the speaker is unmuted.) Similarly, if
active low configuration is selected, the collector of Q118 is used to determine
the state of the speaker. (If the voltage at Q118's collector is low, the speaker
is unmuted, and if the voltage here is high, the speaker is muted.)

Smart Modem Protocol
(SMP) Control

The ASTRO Tone Remote Control Board also provides an RS232 port through
which the Consolette communicates with an ASTRO Console Interface
Module (ACIM) using the Smart Modem Protocol (SMP).
NOTE:

For correct operation, the ACIM must be connected to a Gold
Series Console programmed with System 3.0 Conventional
or later.

Depending on the setting of S100-3, the operation of the Tone Remote Control
board can vary as follows:

In this setup, the Consolette can only be controlled remotely by a tone remote
deskset, via the wireline, as described in “General Description” on page 23
under “Tone Remote Control Board.” The Consolette will report both PTT-IDs
and Call Alert IDs, when applicable, to Accessory Connector 1 (J13). See

In this setup, the Consolette can only be controlled remotely by the Gold Series
Console via Accessory Connector 1 (J13). The Consolette will report both
PTT-IDs and Call Alert IDs, when applicable, to Accessory Connector 1. See
Table 13 on page 30. For a list of supported IDs, see Table 14 on page 31.
As with Tone Remote Control, the Gold Series Console (using Smart Modem
Protocol) can command the Consolette to do the following:
•

Change modes (the number depends on console support)

•

Enable/disable encryption

•

Enable/disable monitor

•

PTT with positive mode

Audio routing to and from the Consolette continues to pass down the wireline.
See “Receive Audio Path” on page 25 and “Transmit Audio Path” on page 26
for audio routing details.

Theory of Operation: Power-Up

!
Caution

Power-Up

Do not connect anything to Accessory Connector 1
other than the supported ACIM connection.
Damage could occur to the Consolette and
unsupported external devices.

The ON/OFF power button located on the ASTRO Spectra/Spectra Plus
control head is disabled before shipment. Therefore, the station is immediately
operational when its power cord is plugged into a live AC outlet. To enable the
ON/OFF power button on the control head, refer to the information in “DIP
Switch and Jumper Settings” on page 8 of this manual. Please note that the
ON/OFF power button on the control head controls the power to the control
head only. For W9 model Consolettes (Digital Remote Control), no control
head is present and the station will become immediately operational when its
power cord is plugged into a live AC outlet.
Once the station is powered, the Power On LED should light up, and the station
should be ready to receive or transmit.

Receive

Since there can be various configurations of the Consolette depending upon
the user's requirements, no detailed receive operating instructions will be given
in this section. However, detailed operating instructions can be found in the
ASTRO Spectra/Spectra Plus radio user’s guide. For information regarding
remote control deskset operation, refer to the applicable instruction manual.

Transmit

Since there can be various configurations of the Consolette depending upon
the user's requirements, no detailed transmit operating instructions will be
given in this section. However, detailed operating instructions can be found in
the ASTRO Spectra/Spectra Plus radio user’s guide. For information regarding
the operation of the digital remote deskset, refer to the applicable instruction
manual.
NOTE:

Power-Up Self-Check
Errors

32

Each Consolette is shipped with the Emergency (Emer)
button disabled. Use the current version of the ASTRO CPS
to enable the Emergency button, if desired.

Each time the radio is turned on, the MCU and DSP perform some internal
diagnostics. These diagnostics consist of checking the programmable devices
such as the FLASH ROMs, internal and external EEPROMs, SRAM devices,
and ADSIC configuration bus checksum. At the end of the power-up self-check
routines, if an error exists, the appropriate error code is shown on the display.
Self-test errors are classified as either “fatal” or “non-fatal.” Fatal errors will
inhibit user operation; non-fatal errors will not. For non-display radios, the error
codes may be read using the Customer Programming Software (CPS) from the
universal connector at the rear of the ASTRO Spectra or Spectra Plus
Transceiver.

Maintenance

Alignment

The advanced design and manufacturing techniques eliminate the need for
traditional tuning tasks for the ASTRO Spectra/Spectra Plus transceiver. All
circuits in the transceiver have been aligned at the factory with specialized
equipment. Alignment in the field should not be necessary or attempted.

Programming
Codeplug
Programming

Configuration items for field programming of the ASTRO Spectra/Spectra Plus
Consolette are shown in Table 16 on page 34. It is important to note that the
field programming setup connects directly to the ASTRO transceiver and not
to the accessory connectors on the rear panel of the Consolette. Therefore, the
first step in programming the codeplug of the Consolette is to remove the top
cover. See “Disassembly and Reassembly” on page 38 for cover removal and
replacement instructions. Once the top cover has been removed, the ASTRO
Spectra/Spectra Plus transceiver can be connected to a PC.
There are two different methods by which the ASTRO transceivers are
connected to the PC, based on whether it is an ASTRO Spectra or ASTRO
Spectra Plus model. The ASTRO Spectra transceiver is connected to the PC
using a Smart Radio Interface Box (RLN1015). The Smart Radio Interface Box
is connected to the 15-pin accessory connector on the rear of the ASTRO
Spectra transceiver via the ASTRO Spectra Interface cable (30-80369B73),
and to the PC via an IBM PC-AT Computer Interface Cable (30-80369B72).
See Figure 11 on page 36. The ASTRO Spectra Plus transceiver is connected
directly to the PC using the HKN6155 Programming/Flash cable connected to
the microphone connector on the front panel of the transceiver. See Figure 12
on page 36. Prior to programming, make certain that external equipment is
disconnected from the accessory connectors on the rear of the Consolette.

FLASHport
Programming

Always be sure you are ordering/using the latest version of the software
package. If you are not sure, contact Motorola Product Services or United
States and Canada Aftermarket Products Division at 1-800-422-4210.
In order to FLASH the internally housed ASTRO mobile, the lid must be
removed from the Consolette. Connect the ASTRO mobile programming cable
(HKN6155_) to the microphone connector on the front panel of the ASTRO
mobile and follow the FLASHport instructions.

Appendix A - Cross Patch Configuration

General Description
The Cross Patch provides interoperability between two systems on different bands, analog or digital or trunking. An
interface cable can be built to allow the interconnection of two ASTRO Spectra/Spectra Plus Consolette stations to
form a repeater system. The information received by Consolette 1 will be retransmitted or repeated by Consolette 2.
Similarly, information received by Consolette 2 will be retransmitted on Consolette 1. The system is a first come, first
served system in that one station does not have priority over the other. Moreover, the Consolettes must be located
in different frequency bands to prevent RF interference from occurring from one Consolette to another.

Detailed Description
To enable Cross Patch operation between two Consolettes, build the cable shown in the Cross Patch Cable diagram
below and connect each dB-25 connector to Accessory Connector 2 of the two Consolettes. If you wish to have the
option of enabling/disabling Cross Patch operation, you must include an in-line switch (or switches) to open and
close the connection between SPKR_UNMUTE and PTT, along with the connection between RX+(LINE1+)† and
TX_AUD(AUD_TX)†. To disable the Cross Patch, the connection between SPKR_UNMUTE and PTT must be open.
This will prevent the Consolette that is receiving information from keying the Consolette it is connected to. In
addition, the connection between RX+(LINE1+)† and TX_AUD(AUD_TX)† must also be switched open to prevent
received audio from one Consolette unintentionally mixing into the connected Consolette's microphone audio.
The PTT for Consolette 2 is derived from the SPKR_UMUTE signal of Consolette 1 which is active when
Consolette 1 is receiving information. RX audio from Consolette 1 is routed to the TX Audio of Consolette 2.
Adjusting the potentiometer (R111 on AIB, R545 on TRC) on the RX Audio path of Consolette 1 will enable the user
to match the transmitter audio input sensitivity of Consolette 2. The behavior of the audio path from Consolette 2 to
Consolette 1 is identical to the Consolette 1 to Consolette 2 path just described.
NOTE: In this configuration, the SPKR_UNMUTE jumper (J15 on AIB, P102 on TRC) should be placed
for active low operation. (See Table 2 on page 9 for AIB and Table 6 on page 11 for TRC jumper
location.)

Appendix A - Cross Patch Configuration

Level Settings
Consolette 1 to Consolette 2 Path
1. Connect Consolette 1 to Consolette 2 via the cable described above.
2. Connect a signal generator or communications analyzer to Consolette 1.
3. Connect Consolette 2 to a modulation analyzer or communications analyzer. Set the analyzer up to measure
deviation level.
4. Apply a –47 dBm on channel RF signal modulated with a 1 kHz tone at 60% FSD into Consolette 1. Consolette
1 will now be receiving and Consolette 2 will be transmitting.
5. Adjust the RX Audio path potentiometer (R111 on AIB, R545 on TRC) on Consolette 1 until 60% FSD is
obtained on the Consolette 2 modulation analyzer or communications analyzer.
6. Turn off the –47 dBm RF signal.

Consolette 2 to Consolette 1 Path
1. Connect Consolette 2 to Consolette 1 via the cable described above.
2. Connect a signal generator or communications analyzer to Consolette 2.
3. Connect Consolette 1 to a modulation analyzer or communications analyzer. Set the analyzer up to measure
deviation level.
4. Apply a –47 dBm on channel RF signal modulated with a 1 kHz tone at 60% FSD into Consolette 2. Consolette
2 will now be receiving and Consolette 1 will be transmitting.
5. Adjust the RX Audio path potentiometer (R111 on AIB, R545 on TRC) on Consolette 2 until 60% FSD is
obtained on the Consolette 1 modulation analyzer or communications analyzer.
6. Turn off the –47 dBm RF signal.

Radio-Wide Changes Using CPS
The Cross Patch uses the SPKR_UNMUTE signal from Consolette 1 as a PTT signal to PTT Consolette 2.
Furthermore, the SPKR_UNMUTE signal is derived from voltage changes on the speaker leads. The speaker
voltage changes if voice audio is present or if alert tones are present. Therefore, all the Alert Tones should be
turned OFF using CPS. This will prevent unintended mobile PTTs. For example, if TX Clear Alert Tones are enabled,
when Consolette 1 receives a signal, it PTTs Consolette 2. This sends an alert tone to Consolette 2's speaker, which
then causes Consolette 1 to transmit, etc., causing cyclical keying and unkeying of both Consolettes.
To disable the Alert Tones, disable the following fields in ASTRO Spectra or ASTRO Spectra Plus CPS:
1. Radio Configuration Radio Wide → Alert Tones
-

-

Power Up Self Test Alert Tone

2. Radio Configuration → Secure → Secure Configuration → Advanced
NOTE: These fields will be active only if the “Secure Hardware Equipped” field is enabled in the Radio

Caution

When using the Cross Patch, you may exceed the
duty cycle rating of the Consolette. If this condition
is expected, the customer may want to reduce the
RF power output of the Consolette.

Audio Degradation Issues
The Consolette Cross Patch Interface is a base band audio interface that can be used to interconnect the following:
•

Analog to Analog systems

•

Digital to Analog systems

•

Analog to Digital systems

•

Digital to Digital systems

Analog to analog patch systems should experience no audio degradation since there are no vocoders in the system.
The audio will not be degraded in the digital to analog or analog to digital patches since the voice audio is only
vocoded once. The digital to digital patches will experience degraded audio. The repeated voice will not be as
intelligible as the original digital audio. The voice audio that passes through the patch is vocoded twice, and therefore
isn’t quite as sharp as the original. The small artifacts of the first vocoding are amplified and added to by the second
vocoding. The net result is voice that isn’t as intelligible as the high quality first vocoding. The voice has some audio
aberrations, but mainly it’s harder to understand what is being said. The degree of intelligibility loss varies with the
type of vocoder. Field experience has shown that VSELP is affected more than IMBE, but both are degraded from
the original message.
