Battery Safety
Battery Transportation
Rechargeable lithium batteries are subject to special regulation by U.S. and
International laws, particularly regarding transportation on passenger aircraft.
However, individual batteries installed in consumer electronics are not restricted,
provided there are only the correct numbers and types of batteries as may be needed
to operate the electronic equipment.
Your Tempest Wireless Intercom System includes rechargeable lithium-polymer batteries that power the BeltStations. To
ensure that there is no violation of U.S. or International laws, and to ensure your own safety, always:
•
Transport rechargeable lithium batteries installed in the equipment they are intended to power.
•
Transport spare batteries in a padded case, separated from one another.
•
Never transport your rechargeable lithium batteries bundled together.
•
Never transport more than 12 lithium batteries in a single package.
Lithium-polymer batteries include a chemistry that is intended to overcome the dangers associated with lithium ion
batteries. In addition, the batteries that accompany your Tempest Wireless system include protective circuits to further
reduce the possibility of a dangerous reaction associated with charging or discharging beyond safe limits. With reasonable
care you can expect many years of safe and reliable power from your batteries.
Tempest batteries are not subject to transport regulations of dangerous goods because they fulfill the following regulatory
provisions:
»»
ADR 188
»»
IATA A45
»»
IMDG 188
Battery Storage
Long-term storage of batteries at maximum charge can result in permanent loss of capacity.
For long term storage of batteries, charge/discharge the batteries to approximately 60% of capacity. Batteries stored for
longer than one year should be recharged to 60% annually.
Trickle charging is not recommended due to the very low self discharge rate of the batteries.
As with all batteries:
•
Do not burn.
•
Do not expose batteries to excessive heat such as sunshine, fire or other heat sources.
•
CAUTION – Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type.
•
Properly dispose of used batteries promptly.
•

Maintenance and Care
Cleaning
Generally, the Tempest Wireless hardware should be cleaned only with a dry cloth. A soft cloth with rubbing alcohol may
be used to wipe the units if needed. Never spray solvents or chemicals onto the units.
Because of Tempest’s weather resistant design, it is not highly susceptible to dust or airborne contaminants. However, all
electronic devices can be susceptible to particulate contamination. If exposed to an extremely dusty environment, contact
an authorized Tempest service center for internal cleaning.
Temperature and Humidity
Ideally, all electronics should be stored and used in a controlled environment with moderate temperature and humidity.
Tempest components are designed to be very durable, and can tolerate a wide range of environmental conditions.
Install the BaseStation in a location where it will not be exposed to extreme weather conditions. Protect the unit against
dust or moisture. Always protect any AC power connections from the elements with safety in mind.
For more extreme environmental conditions, the BaseStation can remain in a secure location with antennas for the
BaseStation located remotely and connected by low-loss 50 ohm coax cable, or the optional Remote Transceiver can be
used.
The Tempest Remote Transceiver is weather resistant, with gaskets intended to prevent moisture entry from the top and
sides. The CAT-5 cable connection on the bottom is not water tight. If it is to be used in an environment subject to blowing
rain, snow, fog or high humidity, protect the transceiver with a cover that will not interfere with the RF.
The BeltStations are designed to work wherever people work. While the BeltStation design is weather resistant, the headset
XLR connector on the bottom is not watertight. BeltStations should not be submerged in liquids. Protect the battery
compartment from water when changing batteries. The battery compartment offers a route to the electronic circuitry.

Tempest®900 4-Channel Wireless Intercom System
Theory of Operation
Tempest is a DSP (Digital Signal Processor) based, full duplex, wireless intercom system. It is a digital, point-to-point
communications system, operating in 26 MHz of spectrum in the 900MHz frequency band. This band allows users to
operate with no license requirements in most locations.
The 900MHz band offers many benefits. There are, however, a wide variety of technologies and users competing for clear
spectrum in this limited band. Tempest utilizes patented and proprietary technologies to ensure a robust and reliable RF
link under a wide variety of physical and RF environments. This level of reliability is the most important attribute of any
wireless system.
Tempest utilizes proprietary, Frequency Hopping Spread Spectrum (FHSS) technology that has seven U.S. patents. Multiple
BeltStation access is achieved by implementing Time Domain Multiple Access (TDMA) with Frequency Shift Keying (FSK)
modulation. Tempest uses an Algebraic Code - Excited Linear Prediction (A-CELP) voice compression algorithm to reduce the
bandwidth necessary for transmission and yet maintain the highest possible voice intelligibility. In addition, this algorithm
utilizes advanced lost packet masking technology, which greatly reduces the affect of packet loss, possible in all Digital RF
transmission schemes. The loss of audio packets is managed by the algorithm to reduce the possibility of detecting a loss
of audio.
The incorporation of various diversity techniques provide an RF system that is robust and reliable under greatly varying
operational conditions. Because of this inherent design, Tempest delivers superior operational range and greater levels of
interference and multi path fade rejection. Covering extremely large areas or multiple coverage locations can be problematic
with traditional wireless intercom systems. Tempest utilizes iSelect™ on-command roaming to allow users to move from
one area of coverage to another. iSelect allows Tempest users to easily choose the desired coverage area by selecting
the BaseStation they want to communicate through. The BeltStation (remote) remembers the last 64 BaseStations with
which it has been Paired. When a different BaseStation is selected, the hopping pattern and key code of the BeltStation is
synchronized to the selected BaseStation and the BeltStation logs into the BaseStation.
Audio latency is a critical factor in all digital systems. The hop duration in Tempest is intentionally kept very short - under
5ms. This short hop duration limits the amount of data that may be lost in any one hop. More importantly, it reduces system
latency, which can cause undesirable echo. Total one-way (BeltStation to BaseStation) system latency is less than 50ms.
Even with this short system latency, unwanted and distracting echo will occur when interfacing with hard wired party-line
intercom systems unless echo-reduction technology is implemented. Echo is primarily the result of inefficiencies in the
conversion of the two-wire signal. This condition exists in analog systems as well, but it does not cause unwanted echo
8
Tempest®900 4-Channel Wireless Intercom System
because there is no system latency delay. Tempest uses advanced echo-cancellation algorithms to eliminate this echo.
Wireless intercom systems are often used in high-noise environments that require special design consideration for effective
operation. Tempest operates extremely well even in very high ambient noise levels. This is primarily due to specific design
criteria which allow Tempest to achieve an audio dynamic range of greater than 94dB. This is more than double that of
most other digital wireless communication systems. This design makes Tempest ideal for use at sporting venues, concerts
and other events where unwanted noise levels are high.
Tempest offers a host of features and technology to ensure that it performs well in almost all production environments
virtually anywhere in the world with no licensing requirements or fees.

BaseStation Overview
Front Panel Left
1- Local Headset Connector
The 4-PIN XLR male headset connector is compatible with most Dynamic or Electret headsets that have 4-PIN XLR
female connectors. This headset connector allows a user to communicate on any one of the four intercom channels.
Controls for this connector are located to the immediate right. The mic gain for the Local Headset can be adjusted
from the “Set Mic Gain” menu, under the “BaseStation Settings.” (Note: the headset must be purchased separately.)
2- Talk Button and LED
The Talk button works in conjunction with the Local Headset Connector. The Talk button enables or disables the
microphone for the local headset. A blue “TALK” LED will illuminate when the mic is enabled. Tempest uses an
intelligent latching method for talk buttons. Pressing TALK momentarily will cause the mic button to latch. The blue
“TALK” LED will stay lit and the microphone will remain enabled. Pressing and holding TALK will cause the button to
act in a momentary fashion. The blue “TALK” LED will remain lit and the microphone will remain enabled only as long
as the button is pressed.
3- Call Button
The Call button sends a wired intercom-compatible call signal to any wireless BeltStation and any 2-Wire hard wired
intercom device on the intercom channel currently selected for the Local Headset.
4- Mic Kill Button
The Mic Kill button sends a signal to wireless BeltStations that disables Talk buttons that are enabled. This button is for
the wireless system only. No Mic Kill signal is sent out to the hard wired intercom. Mic Kill signals from the hard wired
intercom are accepted and passed through to the wireless users.
A momentary press and release of the MIC KILL disables any wireless BeltStation Talk button currently enabled on
the selected channel, as well as the BaseStation local headset connector. If the Mic Kill button is pressed and held
for three seconds, all wireless BeltStation Talk buttons on all channels are disabled. A wireless BeltStation user may
enable a Talk button at any time after the Mic Kill button is pressed and released. The “OFF” indicator appears in place
of the “TALK” indicator on the BeltStation display and the user will not hear sidetone if both Talk buttons are OFF.
5- Local Headset Channel LEDs
The four Local Headset Channel LEDs labeled A through D indicate the currently selected intercom channel for
the BaseStation local headset. Only one channel may be selected at a time. Pressing the Volume control while in
Operational Mode cycles the Channel LEDs in order from A through D.
6- Peak LEDs
The four PEAK LEDs indicate when the mic audio from the local headset is reaching a peak level and is about to
enter into limiting. These indicators should not be illuminated during normal use. The mic gain for the Local Headset
connector can be adjusted from the “Set Mic Gain” menu, under “BaseStation Settings.” Setting the mic gain correctly
is critical for quality communication audio.

Tempest is a radio system. Choosing a location for your Tempest BaseStation and the associated antenna is one of the most
important factors to ensure proper system operation and achieve maximum operational range. As covered in the General
Information and Theory of Operation section of this manual, broadcasting and receiving RF signals can be greatly affected by
physical and electromagnetic barriers.
Following the guidelines below for selecting a suitable BaseStation and antenna location will help to ensure that your
system operates properly and achieves the maximum possible operational range.
See the Antenna Configuration section of this manual for details about recommended cable type and other important
information about connecting the antenna to the Tempest BaseStation.
BaseStation Location
The location of the BaseStation is important, but it is the location of the antenna that will ensure maximum system
performance and operational range. Whenever possible, locate the BaseStation in close proximity to the desired coverage
area. If this is not possible consider using the optional Remote Transceiver to achieve optimal antenna positioning. It is
not recommended to use RF coaxial cable lengths longer than 25 feet to remote the antenna, as this will degrade system
performance and operational range.
•
•
•
•
•
•
The BaseStation must have a source of electric power available. This can be either AC or battery (DC) power.
The front panel of the BaseStation must be accessible for configuration.
The front panel may be used as a communication portal.
The rear panel must be accessed for making wired system connections.
The Tempest BaseStation should be in a location that has adequate ventilation and is not subject to extreme
temperatures and humidity.

•
Always use a stable and secure platform or rack mount system.
23
Tempest®900 4-Channel Wireless Intercom System
Power Connections
The Tempest BaseStation can be powered by AC or DC power, and uses an auto-switching power supply; therefore, if both
AC and DC are connected, the BaseStation will automatically switch to DC in the event AC power is interrupted.. The front
panel ON/OFF switch controls AC and DC power coming into the BaseStation. If AC and DC are both connected, the DC will
act as a power supply backup in the event AC power is interrupted.
AC Power Connection
»»
Always connect the power cord to the Tempest BaseStation before connecting to the outlet.
»»
Tempest BaseStations are powered by an internal power supply. The cord to connect the internal power supply
to the mains supply must conform to the following:
»»
»»
»»
»»
The mains power cord shall have an IEC C13 connector at one end and a mains power plug at the other end.
An IEC C 13 plug has three pins, the centre pin carrying the earth/ground. The other two pins carry neutral
and live circuits.
»» The conductors of the mains cords shall have adequate cross-sectional area for rated current consumption of
the equipment.
»» The mains plug that connects to the mains supply must be approved for use in the country where the
equipment is to be used.
»» The mains power cord must be an IEC mains 3-wire grounding power cord complying with standard
IEC60320; IEC320/C13.
Mains power cords used in the US must also comply with standard UL817.
Only use AC power from 85 to 260 VAC at 50 – 60 Hz.
DC Power Connection (Battery)
»»
To power the Tempest BaseStation from DC power, you must provide an appropriate DC power input cable.
»»
The DC power input jack on the BaseStation is a Switchcraft 722RA.
»»
The mating plug is a Switchcraft S760 - 2.1mm x 5.5mm power plug. The connector should be wired as center
positive.
»»
Always use appropriate wire of an acceptable gauge and length for your application. The minimum
recommended wire is 26 gauge at not more than five feet. If 10 feet is required, the minimum gauge would be
24.
»»
Only use DC power from 11 to 32 VDC. The Tempest BaseStation will draw approximately 12 Watts (990mA at
12VDC).
Powering ON the BaseStation
Plug in the BaseStation.
Turn the front panel ON/OFF switch to the ON position.
The BaseStation undergoes an initialization cycle. During this power-up cycle, the LEDs flash and the LCD screen updates.
Approximately 4 seconds after turning ON the power switch, you will see a splash screen showing the installed firmware
version. The splash screen lasts approximately 6 seconds before advancing to the normal Operation screen. If connected to
a Local Area Network, the DHCP settings (IP address, MAC address, etc) will then display until MENU is pressed to escape or
until the normal time out is completed. The system will then display the main Operation screen and will be ready for use.
Note: When connecting/disconnecting a Remote Transceiver to the BaseStation, be sure to power cycle the BaseStation after
re-connecting the Remote Transceiver. (When power cycling, turn off the power to the BaseStation and wait 10 seconds
before turning it back on.) Failure to power cycle may result in erratic operation.
24
Tempest®900 4-Channel Wireless Intercom System
Antenna Location
24”
Proper antenna location is essential for optimum system performance and
maximum range. Antenna positioning is important with all RF systems and in all
applications.
Locate the Tempest BaseStation antenna as high as possible for your application
to maximize line-of-sight RF operation. Positioning the antenna higher than head
level is the minimum acceptable height for most applications. Maintaining line of
sight between the BaseStation antenna and the BeltStation(s) is ideal.
When using multiple BaseStations, keep as much space between the antennas as
possible, but a minimum of 24 inches is recommended. Increasing the distance
between antennas to may help to improve performance.
When rack mounting the Tempest BaseStation or when it is stacked with other equipment, always remote mount antennas or use the Tempest Remote Transceiver to ensure
maximum operational range.
If possible, locate the antenna(s) away from any metal obstructions and away from walls or other significant structures, by
at least 24 inches.
When using omnidirectional (Whip) antennas, always locate the antennas as close to the center of the coverage area as
possible. Omnidirectional antennas have a circular pattern and radiate RF energy equally in all directions at approximately
a 90° angle to the element of the antenna.
Other antenna options are available including directional and higher gain antennas. Please contact your dealer or distributor
for more information on optional antennas. Only use approved antennas. Unauthorized antennas may be illegal.
Using more than one BaseStation permits an increase in the number of wireless BeltStations within an area, or by utilizing
Tempest’s iSelect roaming feature, allows increasing the area covered and even allows for the creation of separate, but
adjacent or overlapping coverage areas. The number of BaseStations that can be utilized in a system is limited by RF
competition between systems and several other RF conditions. Judicious placement of antennas can help facilitate a large
number of wireless BeltStation users on a single system.
25
Tempest®900 4-Channel Wireless Intercom System
Antenna Configurations
Option 1
Install the BaseStation in the center of the area
of communication, with antenna installed on
the back of the BaseStation, having a clear
line of sight in all directions.
When attaching the supplied ½ Wave Omnidirectional Whip antenna directly to the back of the BaseStation, always ensure
that the antenna is firmly seated, is not cross threaded, and is located away from any metal obstructions. Keep the antenna
away from walls or other significant structures by at least 24 inches.
Option 2
Install the BaseStation in an equipment
rack (1 RU) and use an optional LMR195, a 50 ohm coax up to 10 ft to mount
the antenna above the equipment rack.
(5 ft of LMR-195 coax induces about 1
dB of attenuation.)
To remotely locate antenna, always use high quality, low loss, 50 ohm RF cable terminated with an RP-TNC connector for
the BaseStation side connection and the appropriate antenna mating connector on the other end. LMR-195 (or equivalent)
coaxial cables can satisfactorily be used in lengths up to 10 feet. LMR-400 coaxial cables (or equivalent) can be used at
lengths up to 25 feet. Longer RF coaxial cable runs are not recommended due to signal attenuation in the cable.
Option 3
Install the BaseStation in a convenient location and use the Tempest
Remote Transciever connected with CAT 5 cable and RJ-45 connectors to
position antennas in the most suitable location.
When locating the antenna at distances greater than 25 feet, use the optional Tempest Remote Transceiver. The remote
transceiver allows locating antennas up to 1,500 feet away from the BaseStation without the RF signal loss that is associated
with using RF cable. The antenna can be mounted directly to the Tempest Remote Transceiver, or they can be separated
from the remote transceiver using high quality, low loss, 50 ohm RF cable as listed above. See the Tempest Remote Transceiver
section of this manual for more information on the setup and use of the remote transceiver.

The Tempest Remote Transceiver is an optional accessory that allows antennas to be located up to 1,500 feet away from
the BaseStation without the RF signal loss that is associated with using long runs of coaxial cable.
The Tempest Remote Transceiver connects to the rear of the BaseStation with standard CAT-5 wiring with RJ-45 connectors.
Note that there are two RJ-45 connectors on the back of the BaseStation and they are not interchangeable. The second
RJ-45 is for a LAN connection.
»»
Install the BaseStation in a convenient location.
»»
Install CAT-5 cable so that it is protected from electronic interference as much as possible.
»»
Install the Transceiver and antennas in a location that provides the best RF coverage.
»»
Connect the CAT-5 cable to the BaseStation and the Transceiver.
»»
When the BaseStation detects the presence of the Transceiver, there is a brief automatic configuration process
before the Transceiver takes over the radio function from the BaseStation.
There is one RP-TNC antenna connector on the top of the
transceiver, allowing for connection of a half wave antennas
or alternate antenna configurations. Always ensure that the
antenna is securely connected for proper system operation.
The Transceiver antenna connectors are made to be water
resistant, so outdoor use is acceptable. The cable connections
on the bottom of the transceiver are not water tight, so
always protect from immersion. In severely blowing rain, it
may be prudent to protect with an RF transparent cover such
as a Ziploc bag.
Coaxial cable may be used to connect alternative
antenna options.
Power cycle the BaseStation when connecting/
disconnecting the Remote Transceiver. (When
power cycling, turn off the power to the
BaseStation and wait 10 seconds before turning
it back on.) Failure to power cycle may result in
erratic operation.

Tempest®900 4-Channel Wireless Intercom System
Maximizing System Performance and Operational Range
Radio waves can be significantly affected by walls, windows, or other physical barriers. Concrete or metal walls can be
of particular concern. Some tinted windows are also significant barriers to RF. Always position antennas to minimize
interference from all barriers.
A human body can be a barrier to the radio signal, especially when operating near the limit of the signal’s range. If you
experience interference, turn the BeltStation toward the BaseStation antenna.
Electronic equipment can generate radio interference. Install the BaseStation antenna away from sources of electrical
interference. Be aware of the presence of nearby electronic equipment that may cause interference as you move about
while wearing the BeltStation.
Reflected RF signals, called multi path interference can cause inter symbol interference resulting in compromised audio.
Multi path interference should be suspected when audio is imperfect and there is no other obvious cause. Typically,
inter symbol interference requires a reflection path that is at least a few hundred feet. It is most likely to occur in a large
enclosed venue with highly reflective walls or ceiling. If inter symbol interference is suspected, relocate the BaseStation
antenna and/or try a directional antenna to help eliminate received reflected signals.
Line-of-sight operation between the BaseStation antenna and the BeltStations will always produce the maximum system
performance and operational range. Minimize obstructions between the BaseStation antenna and the BeltStations when
possible.
Use an optional directional antenna to improve system performance and operational range. A directional antenna focuses
the RF signal into a smaller area. When the BeltStation is located within this focused area of energy, it will have a more
powerful signal, which will improve range. Note: Directional antennas are currently not available for 900 MHz Tempest models.
Only use approved antennas. Unauthorized antennas may be illegal.

Network Number and Lockout Key
The Network Number determines the RF frequency hopping pattern for the BaseStation and its corresponding BeltStations.
This is a key operational parameter and is represented by a number between 0 and 36.
When using multiple collocated Tempest BaseStations, it is imperative that Network Numbers are properly coordinated.
Synchronized BaseStations must utilize the same Network Number Group for optimal performance to be achieved. Under
ideal conditions, three to five Tempest 900 BaseStations can be utilized in one Network Number Group. For example, a
configuration using three Tempest 900 BaseStations would assign each BaseStation a Network Number (0,1,2) from Group
One. The chart below outlines each Network Number Group and its capacity. However, when collocating more than three
BaseStations, it is highly recommended to contact your Tempest Applications Engineer for assistance with system
implementation.
s
*When collocating more than three BaseStations, it is highly recommended to
contact your Tempest Applications Engineer for assistance.
The Lockout Key prevents systems with the same Network Number from trying to communicate with each other and is
represented by a number between 0 and 255. BaseStations that are collocated within the same installation may have
the same Lockout Key as long as the Network Numbers are different. Lockout keys serve as differentiators for systems
using the same Network Number. Together, the Network Number and Lockout Key represent more than 11,000 possible
combinations to minimize the possibility of inter-system interference.
The Network Numbers and Lockout Keys for Tempest Wireless BaseStations are set to a factory default before leaving the
factory. It is always recommended to adjust the Network Number and Lockout Key upon initial set up out of the box. Failure
to set a unique Network Number and Lockout Key may result in poor system performance caused by interference from
another Tempest Wireless system using the same Network Number and Lockout Key. Because of the requirement to pair
every BeltStation to each BaseStation that it will communicate with, it is not possible to manipulate Network Numbers and
Lockout Keys at a BeltStation to gain unauthorized access to a communication channel
Collocated BaseStations must use Network Numbers from the same Network Number Group;
failure to do so can lead to poor performance.

Tempest®900 4-Channel Wireless Intercom System
Set Display Mode to Static or Dynamic
The Static or Dynamic selection only affects the order that the BaseStation LCD Operational screen displays BeltStation
information. “Static” will be the preferred choice for users who want to ensure that a BeltStation that is logged in will
always appear in the same location (slot) on the BaseStation display and are using only one BaseStation.
Dynamic is the default setting. Dynamic display mode always displays BeltStations in alpha-numeric order by name, so “Dir”
appears before “LitMgr,” which appears before “StgMgr,”. BeltStations can change slots depending on which BeltStations
are logged in at any given moment. Empty slots are always on the right of the Operation screen. Dynamic is the preferred
choice for users utilizing iSelect roaming between multiple BaseStations.
On the BaseStation, under “Tech Menu,” in the “Display Slot Assignments” menu, choose Static or Dynamic.
When selecting Static slot assignments, you must also enter the “Base Slot” section of the “Tech Menu” on each BeltStation
and assign each BeltStation a different slot (1 – 5). If you have a BeltStation that displays the message “Slot Occupied,” it
means two or more BeltStations are assigned to the same slot number.
When operating in Shared Mode, the Tempest BaseStation must be in Dynamic slot
assignment.
Name Each Station
Name the BaseStation with a descriptive name. This is especially helpful when iSelect Roaming will be used to roam
between BaseStation coverage areas. It is also helpful when the BaseStation or T-Desk is used to monitor and manage the
BeltStations. The BaseStation name can include up to 14 characters. Prior to a name being assigned, a hexadecimal serial
number is displayed as a default.
The BaseStation name will appear on the banner (top line of the BaseStation display, with white-on-black lettering), on the
BeltStation display, and in the BeltStation’s menu under “Select Base.”
The BeltStation will accept 14 characters in the name, but only the first six characters of the BeltStation name can be
displayed on the BaseStation Operation screen. If the BeltStation is named “Camera 1,” then “Camera” will be displayed on
the BaseStation slot for that BeltStation because of the six character limit. If the BaseStation will be used to monitor and
manage the BeltStations, the BeltStation name should be limited to six characters. To name each BaseStation:
1. On the BaseStation press MENU and select “BaseStation Settings,” then “Name BaseStation.”
2. Rotate the Volume control to move the underscore “_” to select the character to be changed.
3. Press ENT and notice the underscore changes to a pointer “Λ” under the selected character.
4. Rotate the Volume control to scroll through the character list. Press ENT to select the new character. Characters always
replace and never insert. Repeat as needed.
5. Press ENT to save the new name after all characters are complete. Failure to press ENT to save will clear all changes.
6. Press MENU to escape to the Operation Mode screen.
Naming the BeltStation works the same as naming the BaseStation. On the BeltStation, press MENU and select “Belt
Settings,” then “Name BeltStation.” Use the Volume control and the ENT button to select and change characters. Press ENT
to save the changes.
BeltStation names can be changed wirelessly from the BaseStation’s menu or from T-Desk when the system is on a local
area network.

Tempest®900 4-Channel Wireless Intercom System
BaseStation Headset Connection and Controls
The BaseStation headset connection is a functional user communication point, and may also be used for setup and
troubleshooting. The Front Panel Headset can communicate on any one of the four intercom channels. Controls for this
headset are located just to the right of the connector, and in the menu on the BaseStation Settings screen.
The front panel headset connector is a 4-PIN XLR male. A compatible headset must be provided by the user.
The TALK button enables or disables the microphone for the local headset. A blue LED will backlight the word “TALK” on
the TALK button when the mic is enabled. Always keep the microphone disabled (TALK OFF) when not in use.
Tempest uses an intelligent latching method for TALK buttons. Pressing the TALK button momentarily (less than two
seconds) will latch the mic button. The blue “TALK” LED will remain lit and the microphone will remain enabled. Pressing
and holding the TALK button will cause the button to act in a momentary or push-to-talk fashion, so the blue “TALK” LED
will remain lit and the microphone will remain enabled only as long as the button is pressed.
In Operational Mode, turning the Volume control adjusts the volume of the audio of the local headset. Turning the
Volume control clockwise increases the audio level while turning the control counter clockwise decreases the level. The
Volume control knob is also a push button. Pressing the Volume control cycles the Channel selection and LEDs in order
from A through D.
The four Peak LEDs indicate when the mic audio from the local headset is reaching a peak level and is about to enter into
limiting. These LEDs should normally be OFF.
Set the Mic Gain for the Local Headset
Set the Mic Gain properly to assure the best audio quality. To set the Mic Gain for the Local Headset:
1. Press MENU to enter Menu Mode.
2. From the Main Menu select “BaseStation Settings,” then “Set Mic Gain.”
3. While at the “Set Mic Gain” screen, talk into the local headset microphone in a louder than normal level and adjust the
Volume control until the Peak LED for the selected channel just starts to light at the loudest parts of the audio. Press ENT to
accept the changes.
When the Mic Gain is set too high, it is possible to induce feedback or echo. When set too low, words can be clipped
by the low level noise gate, or may sound too quiet to other listeners. Headsets by different manufacturers or different
models of headsets will require widely varying Mic Gain settings. When setting microphone gain, it is best to err toward
a setting that is too low, rather than too high. This will help reduce unwanted echo in the system when that microphone
is enabled.

Press MENU + ENTER to unlock.
Call Function
On the BaseStation front panel, select a channel by pressing the Volume control. Press and hold CALL for as long as you
want the Call signal to go out on the channel.
A Call signal will be received by users who are listening on the channel that originated the Call signal.
On the BaseStation, an active Talk button is not required to send a Call signal, and the Call signal is routed to the channel selected for monitoring. On the BeltStation, a Call signal is sent only when the Talk button is enabled, and only on the channel(s) selected for Talk.
Stage Announce (SA)
The Stage Announce (SA) function in the Tempest BaseStation is used to send a wireless BeltStation microphone signal to
a dedicated external audio output. When a wireless user presses the STAGE button on the BeltStation, their audio is rerouted from the selected intercom channel(s) and is sent to the BaseStation rear panel SA connector. In addition, a relay
closure contact is available on the RELAY connector on the back of the BaseStation. Pressing the STAGE button enables the
headset microphone, regardless of the status of the Talk buttons. If enabled, all BeltStations can access this feature.
The Stage Announce output connector is an XLR-3M. The Stage Announce connector is balanced and transformer isolated
and outputs nominal line level audio from -12 to +12 dBu. The Stage Announce connector output level can be adjusted at
the “Stage Announce” menu screen, under “Wired Intercom Settings.”
In addition, the Stage button may be configured to also control an additional relay assigned to the users BeltStation. See
the GPO Relay section for more details.
35
Tempest®900 4-Channel Wireless Intercom System
GPO Relay Contacts
Tempest Wireless provides six General Purpose Output (GPO) contact closures. These GPO contact closures can be used
for interfacing with other external devices. The Stage Announce (SA) Relay and the five other GPO Relays, enough for each
BeltStation to control one, are available through the DA-15 Relay Connector on the back of the Tempest BaseStation. These
relays can only be triggered from the wireless BeltStations.
The SA Relay function in the Tempest BaseStation is activated by the STAGE button on the BeltStation. The SA Relay remains
closed as long as the STAGE button is pressed.
The user can reassign the following BeltStation buttons and features to control an individual relay uniquely assigned to that
BeltStation:

The relay is made when the assigned button is pressed and remains closed for as long as the button is pressed. The
individual GPO relay can also be triggered by the low battery level alert of the BeltStation. In this case, the relay is made
when the battery level of the BeltStation reaches 10% and remains closed until the battery is replaced or the BeltStation is
turned OFF.
All relay contacts can support 1 Amp at 30 VDC. The relay completes a circuit. Tempest does not supply any power to the
circuit. Since every user will require a custom application, cables for your RELAY connections will require some bench work.

Active Channel Relay
This mode of relay operation can control how all BeltStations on a particular BaseStation function with respect to relays.
When active, any TALK button pressed for a respective channel will close the corresponding relay on the BaseStation. For
example, if any TALK button on “Ch A” is pressed then “Relay 1” will close. If TALK is pressed on “CH B” then “Relay 2” is
closed, “CH C” for “Relay 3” and “CH D for Relay 4.”
BaseStation “Relay 5” may be assigned to any of the existing relay triggers from any or all BeltStations, and the Stage Relay
operates normally. It is not possible to exclude any BeltStation(s) from this mode of relay operation once the BaseStation
has been set into this mode.

Tempest®900 4-Channel Wireless Intercom System
Auxiliary Output
Audio from the Auxiliary OUT Connector can be assigned from any combination of the four intercom channels with Volume
control at the “Aux Out Assignment/Levels” menu. Audio from the Auxiliary OUT connector comes only from the wireless
users and no audio from the hard wired intercom channels is routed to Auxiliary OUT.
While in the “Aux Out Assignment/Level” menu, the front panel Channel Select (SEL) button is used to advance through the
channels and the OUT level control is used to adjust the Aux OUT volume. Adjust to OFF to restrict audio from a channel.
Audio levels are expressed in Decibels (dB). The audio range for Aux OUT are:
»»
Aux Out: -12 dB to +12
The Aux IN and OUT connectors are ¼” Tip/Ring/Sleeve jacks that accept standard ¼” TRS plugs. The Aux IN and OUT
connections are balanced and transformer isolated and operate at a nominal line level audio of - 4 to + 8 dBu.
Reset Memory
There are three options to reset memory: Restore Factory Default, Clear Memory, and Reset Radio Settings. Both the
BaseStation and each BeltStation have a “Factory Default” option in the “Tech Menu.” Browse to the “Tech Menu,” select
“Factory Default,” and choose any of the three options. From the BaseStation, “Restore Factory Defaults” only resets
BaseStation defaults. BeltStation factory defaults can be reset in each BeltStation and changes are relayed wirelessly to the
BaseStation.
Restore Factory Default
This option will restore all settings to factory defaults except pairings and names.
Be aware that restoring factory defaults will have an immediate effect on volume, sidetone, relay selection, Aux In/Out levels, hard wired intercom levels, and Shared Slot settings, among others.
Clear Memory
Occasionally, it may be desirable to remove all previous settings and user defined names, such as when equipment is
transferred to a new project or work site. Clear Memory on a BeltStation will require re-pairing of BeltStations. It may
be necessary to select a Frequency Band due to country specific RF requirements, on the BaseStation.
This option will restore all settings to factory defaults and will delete all user defined names. All entries will be deleted and there is no “undo”.
Reset Radio Settings
This is a BaseStation feature only. Selecting this option will only reset the Frequency Band to “1,” the Network
Number to “0’” and the Lockout Key to “255.” The BeltStation radio settings are determined by the BaseStation.

the BeltStation. Turning the Volume control clockwise increases the audio level while turning the control counter clockwise
decreases the level.
Pressing the “CH A/B or “CH C/D” changes the selected intercom between A or B and C or D respectively. The intercom
channel selected is indicated by the Channel Indicator LEDs located on the outer edge of each talk button, “TALK A/B” and
“TALK C/D.”
In Menu Mode, turning either Volume control allows the user to scroll through the menu options of the current menu
screen. Pressing either control selects the current menu option and is the same as pressing ENTER. A menu item is not
selected and will not take affect until the control, or ENTER, is pressed.
For example, to adjust the Sidetone setting:
•
•
•
•
•
Connect a headset to the BeltStation.
Press MENU to enter Menu Mode.
Rotate the Volume knob and scroll to “Set Controls.”
Press ENTER to select, and scroll to “Sidetone.”
Press ENTER to select the “Sidetone” adjustment.
Sidetone is expressed in Decibels (dB). You will see a level indicator with a numeric value between -30dB to -6dB. You should
speak into the headset microphone at a normal speaking level and adjust the sound of your own voice to a comfortable
level by rotating either volume knob to adjust the Sidetone level. When satisfied, press ENTER to save the adjustment. Press
MENU to move up one level in the menu tree. Press MENU repeatedly to exit Menu Mode and return to Operational Mode.

Battery Selection and Installation
The Tempest BeltStation Battery Compartment holds either one Tempest Lithium-Polymer rechargeable battery or three
standard alkaline AA cells. Lithium-Polymer batteries are the primary power source. High quality alkaline AA cells may be
used in situations where Lithium-Polymer batteries are not available or are not charged. One Lithium-Polymer battery
comes standard with each Tempest BeltStation. Additional Lithium-Polymer batteries may be purchased. Contact your
dealer or distributor to purchase additional batteries. The Lithium-Polymer batteries supplied with your Tempest Wireless
system are warranted for 12 months from the date of purchase.
Lithium-Polymer batteries offer up to nine hours of battery life and recharge in
approximately 2¾ hours.
Lithium-Polymer batteries ship from the factory with approximately 50% charge. It
will not damage the Lithium-Polymer batteries to use them without charging them
first. This will, however result in shorter run time until the Lithium-Polymer battery
is fully charged. When possible, charge Lithium-Polymer batteries to full capacity to
ensure full battery life prior to use.
Using (3) alkaline AA batteries can provide up to four hours of battery life. Use
only high quality alkaline AA cells. This will provide enough time to fully charge the
Lithium-Polymer battery.
To remove the battery door, press down on the thumb markings and pull the battery door toward the bottom of the
BeltStation.
To remove batteries from the battery compartment, turn the BeltStation battery side down and tap the bottom of the
BeltStation on the palm of your other hand.
Please be careful to insert alkaline AA batteries according to the marked polarity. All of the alkaline AA cells must be
oriented the same direction.
If the battery cover does not close properly, the battery may not be inserted correctly.
40
Tempest®900 4-Channel Wireless Intercom System
Charging the Lithium-Polymer Battery
With the Lithium-Polymer batteries installed in the battery compartment, plug the AC
end of the supplied 5VDC Charger/Power Supply into a standard AC wall outlet. Open
the rubberized access cover on the side of the BeltStation and plug the USB end of the
Charger/Power Supply into the USB connector. The Lithium-Polymer batteries will take
approximately 2¾ hours to charge from completely empty to completely full. This time is
the same with the BeltStation turned ON or OFF. A new, fully charged battery should power
a Tempest BeltStation for approximately nine hours.
Fast charging with the supplied fast charger requires a temperature range of 32° – 113° F.
Batteries can receive more than 500 charge cycles, and continue to maintain more than
70% of their power rating. The Tempest battery indicator will maintain its accuracy as
battery life decreases.
Alternatively, remove the Lithium-Polymer rechargeable battery from the BeltStation
and insert it into the optional 5-Bay Battery Charger. The Lithium-Polymer batteries
will take approximately 2½ hours to charge from completely empty to completely full.
See the battery charger manual for additional details.
Power Options
The Tempest BeltStation can be powered by:
»»
Supplied Lithium-Polymer battery.
»»
AA batteries; it is safe to connect a power supply to a BeltStation with AA batteries installed. It will not harm the

Tempest®900 4-Channel Wireless Intercom System
Pairing with a BaseStation
Pair BeltStation to BaseStation:
Confirm that the BaseStation is powered ON and in Operational Mode (not
in Menu Mode) and that the BeltStation is powered OFF. Confirm that the
BaseStation’s Network Number and Lockout Key are adjusted as needed. See the
section on Set Network Number and Lockout Key.
Plug one end of the pairing cable into the BaseStation and the other end into the
BeltStation.
The pairing cable is a standard 3.5mm
(1/8 in.) male to male stereo patch cord.
Turn the BeltStation power ON by pressing and holding the BeltStation Power ON/OFF button for two seconds. The pairing
process will begin automatically. Watch for the message “Pairing Complete” to appear briefly on the BeltStation display.
The BeltStation will automatically re-initialize.
4-channel and 2-channel BeltStations may be paired to either model
BaseStation(s); When a 4-channel BeltStation is paired with a 2-channel
BaseStation operation of that BeltStation is limited to channels A/B and can
only hear one channel at a time.
Adjust BeltStation Slot
The BaseStation Slot Assignment only affects the order that the BaseStation Operational screen displays the BeltStation
information when the BaseStation is in the Static display mode. If the BaseStation is routinely used as a communication port
or for monitoring BeltStations, it may be more convenient to always have the same user appear in the same position on the
BaseStation display. This is a personal preference setting.
In the BaseStation “Tech Menu,” choose Static or Dynamic from the “Display Slot Assignments” screen. Dynamic, the default,
will work without any adjustment, and always displays BeltStations in alpha-numeric order by name.
Static will be the preferred choice for users who are using only one BaseStation and want to ensure that a BeltStation that is
logged in will always appear in the same location (slot) on the BaseStation display. When selecting Static slot assignments,
you must also enter the Tech Menu for each BeltStation and assign each BeltStation a different slot (1 – 5).
The BaseStation default is for Dynamic Slot Assignment. This means that when BeltStations log in to a base, the information
about the BeltStations is displayed on the BaseStation LCD screen in alpha-numeric order according to the name of
the BeltStation. For example, “Dir” appears before “Light1,” which appears before “StgMgr,” but they can change slots
depending on which BeltStations are turned ON. If the default settings are used, nothing is necessary. If the BaseStation
is located in an equipment room and is not routinely used as a communication port or to manage BeltStations, nothing is
necessary. Adjusting so that each BeltStation always appears in the same position of the BaseStation display is a two step
process:
1. Advance to the BaseStation’s “Display Slot Assignment” section of the “Tech Menu” and select Static.
2. In each BeltStation, advance to the “Base Slot” section of the “Tech Menu” and adjust each BeltStation to a different
slot (1 – 5). The BeltStation designated to slot 1 will always appear on the far left of the BaseStation display, with slot 2
appearing in the next position to the right, and so on.
42
Tempest®900 4-Channel Wireless Intercom System
In Static Mode, if a BeltStation is not turned ON, or is logged out due to being out of range, the BaseStation LCD will
display a very obvious “X,” making it easy to see at a glance which BeltStations are currently active.
A Multiple BaseStation system that uses iSelect Roaming must choose to use “Dynamic” slots to ensure that BeltStations
can move from BaseStation to BaseStation when roaming.
Name Equipment
Name the BaseStation with a descriptive name which will appear on the BeltStation LCD display. This is most helpful when
iSelect Roaming will be used to roam between BaseStation coverage areas. The BaseStation name can include up to 14
characters.
Name each BeltStation with a descriptive name. Until the name is changed, a hexadecimal serial number is displayed.
The first six characters of the BeltStation name will be displayed on the BaseStation LCD display. Naming is a personal
preference option and is not essential.
Personal Preferences
To configure each BeltStation, adjust any of the following to suit individual needs. None of these adjustments are required.
Note that more options are available under the “Set Controls” menu and become visible by scrolling.
•
“Lock Keys” to prevent inadvertent changes.
•
“Menu Lock” allows you to lock individual users out of their respective BeltStation menu. Access can only be
regained by entering a 3-digit security key code initially set at the BaseStation.
•
“Switch Base” is a feature under “Lock Keys” that, when enabled, will allow you to manually select a different
BaseStation, even when “Menu Lock” is active.
•
Disable “Battery Alert” to prevent the battery alert tone in the headset.
•
Dim the LCD and LEDs to be less conspicuous in a dark environment.
•
Limit talking to push-to-talk mode by selecting Momentary. Latch is the default.
•
Disable the ability to talk on any channel, but allow listening.
•
Disable the ability to access any channel not required.
•
Adjust minimum and maximum volume levels. In loud environments a higher minimum volume may be desirable,
while in quiet environments a lower maximum volume may be preferable.
•
Volume controls can be set to “Volume Press” which requires a “press and turn” action to adjust the volume levels.
This helps prevent inadvertent adjustments.
•
When Stage Announce functionality is enabled in the BaseStation, the STAGE button can be disabled for individual
BeltStations.
•
The CALL alert can be set to Audible, Vibrate, Both or Disable. The default is Both. A call signal can be initiated by the
CALL button or the TALK button, depending on your preference.
•
When relay functionality is enabled in the BaseStation, select the relay to be activated by the BeltStation. Then
select the BeltStation trigger that will activate the relay.
•
Wireless ISO can be disabled, if desired.
•
Disable “Shared Audio” to eliminate the return audio of a “Shared” BeltStation. When Shared Audio is OFF and the
BeltStation user presses Talk, they will not hear any other audio. When Shared Audio is ON and the Beltstation user
presses Talk, they will hear an echo of themselves, as well as any other listeners on that channel.
43
Tempest®900 4-Channel Wireless Intercom System
Call Function
There are two call methods available in Tempest. The first uses the CALL button to send call signals to any BeltStation or
hard wired user on the active channel. The second method is referred to as “Call On Talk” and uses the BeltStation TALK
button to initiate a call signal. However, the “Call On Talk” feature works independently from all other BaseStation call
settings and can be used to send call signals through intercom channels to attached radios or matrix.
To enable the CALL button, press MENU, select “Set Controls,” select “Call Button,” and select Enable. This is the default
setting.
To set the “Call Alert” preference, press MENU, select “Set Controls,” and select “Call Alert.” Choose to receive a call signal
alert with an Audible tone in the headset, or with a vibration of the BeltStation or Both. The default setting is Both.
To initiate a call, select a channel for talking with the CH A/B or CH C/D buttons and activate the TALK button. Press and hold
CALL for as long as you want the call signal to go out on the channel. A call signal will be received by users who are listening
on the same channel that originates the call signal.
To enable the “Call on Talk” feature, press MENU, select “Set Controls”, then “Talk Buttons”, then “HW Call on Talk”, and
select Enable. The default setting is Disable.
A call signal from the CALL button is sent only when the Talk button is
enabled, and only on the channel selected for Talk.
Program Volume Control
Auxiliary IN can be used to bring program or other audio into the Tempest BaseStation. Audio from the Aux IN port is routed
only to wireless users and is not routed out to the hard wired system.
Program Volume allows each BeltStation to control the mix of program audio (Aux IN) it receives from the BaseStation.
To enable “Program Volume”, press MENU, then “Set Controls”, then “Program Volume” and select one of three options:
1. Off - the BeltStation receives no program audio.
2. Absolute - the BeltStation receives program audio at a level independent of the intercom levels.
3. Relative - the BeltStation receives program audio at a level relative to the maximum intercom volume setting, regardless of
channel. Scroll to the option that applies to your application and press ENTER to save. Your selection will be indicated
with a check mark to the left of the selection.
To adjust the Program Volume on the BeltStation, hold the ENTER button and then turn either of the volume knobs. The
display screen will display “Program Vol” and the numeric level of the volume.
When “Relative” is selected, the program volume is relative to the highest
level intercom channel on the BeltStation. Thus, when listening to program
audio when intercom volume on channel A was at 15 and channel C was at
10, the program volume would be 15. If that intercom level is lowered
below 10, then your new program volume would then correspond to
channel C’s volume level (10).

Set Mic Gain
Set the Mic Gain properly to ensure the best audio quality. To set the Mic Gain for the BeltStation Headset:
1. Press MENU to enter Menu Mode. From the Main Menu, select “Set Controls,” then “Mic Gain.”
2. While at the Mic Gain screen, talk into the headset microphone at a louder than normal level and adjust the Volume control
until the PEAK LEDs just start to light at the loudest parts of the audio. Press ENT to accept the changes.
Mic Gain can be set in the BeltStation without activating the Talk button. This allows private mic gain adjustment during live
events. The Mic Gain can be set for each BeltStation from the T-Desk application.
When the Mic Gain is set too high, it is possible to induce feedback or echo. When set too low, words can be clipped by
the low level noise gate or sound too quiet to other listeners. Headsets by different manufacturers or different models
of headsets will require widely varying Mic Gain settings. When setting microphone gain, it is best to err toward a setting
that is too low, rather than too high. This will help reduce unwanted echo in the system when that microphone is enabled.
Single Channel Mode
Single Channel is a setting that disables the inherent dual-listen nature of a BeltStation and allows a BeltStation to listen/
talk on a single selected intercom channel at a time, without disabling other channels on the BeltStation.
When enabled, select the channel you wish to listen/talk by pressing the channel knob A/B or C/D the same as you would
in dual-listen mode. However, when in “Single Channel” mode pressing A/B or C/D will cycle from one channel to another
and allow for listen/talk only on the selected channel. For example, if the BeltStation is on channel A and the C/D knob is
pressed the unit will change from channel A to either channel C or channel D (whichever was the last accessed.) Pressing
the channel A/B knob would return you to channel A since it was the previous channel. Pressing the channel A/B knob
again would then access channel B.
To enable “Single Channel” mode, press MENU, then “Set Controls”, then “CH Select”, then “Single Channel”, and then
Enable. The default setting is Disable.

iSelect Roaming – Selecting a BaseStation
Installations with multiple BaseStation coverage zones often require users to move from one work zone to another
throughout the day. One of the ways Tempest handles these transitions is with iSelect™ On-Command Roaming. Using
iSelect, a user can easily change their communication from one BaseStation to another BaseStation in just a few seconds.
•
Confirm that the BeltStation has been paired with all required BaseStations.
•
Confirm that there is an available slot on the desired BaseStation. If no slot is open, power OFF one of the
connected BeltStations, wait for 15 seconds, and proceed.
•
Press MENU and select “Select Base.” Scroll to the desired BaseStation and press ENTER. Press MENU to exit.
Tempest Wireless BeltStations remember the last 64 BaseStations to which they have been paired.
Wireless ISO
Wireless ISO (isolate), sometimes referred to as wireless talk-around is a wireless-only intercom feature that allows
communication among wireless BeltStations only. When a wired intercom system is connected, Wireless ISO communicates
through the wireless portion of the system only. The BaseStation front panel headset does not receive ISO audio.
Wireless ISO is enabled by default and is available only on channel A. It is activated by pressing and holding ENTER. ENTER
enables the headset mic regardless of the “TALK A” button.
Wireless ISO only operates in Operational mode. It does not operate in Menu mode.

Wired Intercom Interface to the BaseStation
Each of Tempest’s hard wired intercom channels can interface with a 4-Wire matrix intercom or a 2-Wire party-line intercom.
Tempest supports a 4-Wire intercom interface to most major digital matrix intercom systems and other intercom 4-Wire
devices. Tempest also interfaces with 2-Wire intercom systems including Clear-Com, RTS, and AudioCom (BAL) systems,
as well as compatible brands. Each Tempest intercom channel can interface with one intercom system at any given time.
While it is possible that both 2-Wire and 4-Wire systems may be connected to the same intercom channel simultaneously,
they cannot function at the same time, and this arrangement has the potential to cause undesirable operational
complications, so is not recommended.

Controls
The two 2-Wire Intercom Type Select Switches determine the type of 2-Wire intercom that may
be connected to the corresponding 2-Wire connectors on the rear panel of the BaseStation. ClearCom, RTS, or BAL (AudioCom) can be selected. These switches only affect 2-Wire operation and do
not control 4-Wire operation. The CHAN A&B switch selects the 2-Wire system type for both the A
and the B intercom channels. The CHAN C&D switch selects the 2-Wire system type for both the
C and the D intercom channels.
Always set the 2-Wire Intercom Type Select Switches prior to connecting the 2-Wire intercom to
the back of the Tempest BaseStation. Never change the switch setting while connected to a
wired intercom system. Failure to follow this procedure could damage the Tempest BaseStation
or the 2-Wire hard wired system.
The Intercom Channel Select (SEL) button selects one of the four intercom channels to allow
selection of 2-Wire or 4-Wire functionality and to allow the intercom audio IN and OUT levels
to be adjusted.
Pressing the Intercom Channel Select button once selects Menu Mode on the BaseStation and
displays the Intercom Levels screen on the LCD display. A second press selects channel A. The
intercom channel selected is indicated by one of the four CHAN LEDs located to the right of the
CHAN SEL button and on the LCD screen. Additional presses of the CHAN SEL button advances
through the remaining intercom channels. The next press of the CHAN SEL button will exit
Menu Mode and will cause all of the LEDs to be illuminated.
The 2-Wire/4-Wire Select (SEL) button selects the connection mode for operation of
each of the four intercom channels. Pressing the 2-Wire/4-Wire Select (SEL) button
changes the selected intercom mode between 2-Wire, 4-Wire or no wired connection.

4-Wire (Matrix) Intercom Interface
4-Wire intercom systems use two pairs of wires to carry one full duplex channel of intercom audio - one pair for send and
the second pair for receive. In addition to intercom audio, most systems have separate data lines that carry system data
from the matrix to the remote devices. The Tempest 4-Wire connection is an audio-only interface to 4-Wire systems. Data
can be present on the input cable but no data is utilized in the Tempest BaseStation.
Steps to Configure a 4-Wire Intercom Connection
•
Select 4-Wire connection for the appropriate channels.
•
Make the physical connections with RJ-45s to the Tempest BaseStation and the 4-Wire system.
•
Configure the 4-Wire system to recognize the Tempest Wireless system.
•
Adjust IN/OUT volume levels between the Tempest Wireless System and the 4-Wire system as needed.
Connect the 4-Wire intercom system to the desired channel RJ-45 jack on the rear panel of the Tempest BaseStation. Select
the 4-Wire setting as described in “Wired Intercom Configuration Controls.” That is all that is necessary for Tempest to be
ready to communicate with the 4-Wire system. Perform any necessary configuration for the 4-Wire intercom System and
the communication link should be complete.
RJ-45 Jacks
The top RJ-45 jack is for Channel A and the bottom RJ-45 jack is for Channel B.
You may choose to adjust the IN/OUT levels on the front of the BaseStation if the volume level between the systems is not
acceptable.
Wiring schemes vary and it is important to ensure that the cable is wired correctly for proper system operation. Tempest
utilizes RJ-45 jacks for 4-Wire connection to the BaseStation. Only two pairs of wires are utilized - one to send audio and
one to receive audio. A standard CAT-5 patch cable can be used to connect between the matrix and the Tempest system.

2-Wire (Party-Line) Interface
2-Wire party-line intercom systems carry one or two (depending on the system type) channels of full duplex intercom audio, plus
system power and other information on a single XLR-3M cable (2 wires and a ground). Each 2-Wire intercom type has a different
wiring scheme and unique line characteristics. It is imperative to have the rear panel connections and the front panel settings
adjusted correctly for audio to pass correctly between the systems.
Steps to Configure a 2-Wire Intercom Connection
•
Adjust the Intercom Type Slide Switches to appropriate manufacturer compatible setting- RTS, Clear-Com, Bal.
•
Select 2-Wire connection for the appropriate channels.
•
Make the 3-pin XLR physical connections to the Tempest BaseStation and the 2-Wire system.
•
Null the system.
•
Adjust IN/OUT volume levels between the Tempest Wireless System and the 2-Wire system.
Always confirm that the 2-Wire intercom system is functioning properly before connecting the Tempest Wireless system.
Test each wired communication station before connecting the wireless system. Confirm operation of the wireless system
before connecting to the wired system.
After the slide switch is set correctly, the appropriate channels are set for 2-Wire operation, the XLR cable connections are
made, and power is provided by the 2-Wire system or Master Mode, then audio will pass between Tempest and the wired
system.
Audio may develop an echo that is heard in the wireless BeltStations until the system is nulled. The echo should not prevent
communication but is undesirable. The volume levels into or out from Tempest may need adjusting so that relative volumes
are the same.
Echo Cancellation Menu
In the BaseStation’s Tech Menu is a selection for “Echo Cancellation” (ECAN). This refers to software that assists in removing echo
from 2-Wire intercom connections. Hardware connections need to be optimized with the null procedure to minimize echo in the
physical link so that the software can remove any residual echo.
In the Tech menu, “Echo Cancellation” is “ON” by default, but is only enabled for channels that are selected for operation with a
2-Wire intercom and have a physical connection to a 2-Wire system. See “Nulling” Section of this manual.
If a 2-Wire intercom is never utilized in a system, ECAN can be turned “OFF” to ensure that it cannot create undesirable effects.
This should not be necessary, though, and it is recommended that you keep ECAN “ON” at all times.
ECAN is disabled while the BaseStation’s Auto-Null or Manual Null menu screens are active, to ensure that the hardware is
optimized for echo reduction. When ECAN is enabled, it requires up to 10 seconds of active audio to achieve maximum efficiency.
Brief loud active audio can help accelerate efficiency.
51
Tempest®900 4-Channel Wireless Intercom System
Auto-Null Explained
In 2-Wire intercom systems, inefficiencies in the hybrid circuitries that combine or separate the send and receive audio signals
onto the same pair of wires inherently cause echo. Within analog systems the echo is not noticeable, but when connected to an
extremely sensitive digital system, the echo becomes more problematic.
In order to minimize echo resulting from connection to an external 2-Wire system, it is necessary to optimize the hardware of the
hybrid circuitry in the Tempest BaseStation. Tempest provides a user initiated AUTO-NULL feature that automatically optimizes
the 2-Wire interface. Nulling only impacts 2-Wire hard wired intercom connections.
Auto-Null sends a tone to each of the 2-Wire intercom channel connections. The Tempest Wireless BaseStation DSP monitors the
echo and adjusts the line characteristics (Resistance and Capacitance) to optimize the interface to the external 2-Wire system.
When Auto-Null is initiated, all of the functions of the BaseStation including communication are interrupted. The Auto-Null
process takes approximately 10 seconds. Intercom levels may need to be adjusted after the 2-Wire intercom lines have been
nulled.
During Auto-Null, wired intercom users will hear the nulling tones and communication will
be interrupted. It is recommended that this feature should be used only during setup and
not during live events.
Auto-Null Procedure
Turn OFF all TALK buttons on both the wired and wireless systems. Since Tempest monitors a self generated tone to adjust
the null characteristics, any sounds entering through either the wired or wireless intercom systems will interfere with the
nulling process. When the Auto-Null or Manual Null menu screens are accessed, Tempest sends a Mic Kill signal to all
wireless BeltStations, but the wired communication stations will need to be turned OFF individually, or a hard wired Mic
Kill signal will need to be initiated.
On the Tempest BaseStation press MENU to open the Main Menu. Rotate the Volume Control to scroll through the menu
options to the “Wired Intercom Settings” and select “Auto-Null.” Select “Null Now” to start the Auto-Null process. Normal
functions will be interrupted for about 10 seconds during the Auto-Null process. Progress of the null process can be
observed on the BaseStation LCD display.
The BaseStation display will indicate “Auto-Null Complete” once the Auto-Null process is completed. Press MENU to escape
to the Operational screen.
Activate Auto-Null for new connections or whenever the 2-Wire system changes significantly, such as when additional
wired BeltStations are added or removed, or when cable lengths are changed significantly.
Test for Echo
Talk into the wireless system for at least 10 seconds to test for echo. Echo Cancellation (ECAN) software is disabled in the
Auto-Null and Manual Null screens to ensure the best hardware null. Press MENU to exit the nulling menu screen, and to
enable ECAN. When ECAN is first enabled, it requires up to 10 seconds for it to achieve convergence. There will usually be
some noticeable echo during the first few seconds of testing, but it will diminish over time as the ECAN software converges
to an inaudible level. Brief louder active audio can help accelerate efficiency.
If multiple BaseStations are connected by 2-Wire intercom connections, each BaseStation
must be nulled separately. Null one BaseStation at a time.
52
Tempest®900 4-Channel Wireless Intercom System
Manual Null
Generally, Auto-Null will adequately control the inherent echo caused by the 2-wire hybrid circuitry. However, “Manual
Null” is available if there is residual echo.
If echo persists after testing for at least 30 seconds:
1. Turn OFF all TALK buttons on wireless and wired equipment. Since Tempest analyzes a tone to adjust the Null characteristics,
any sounds entering through the wired or wireless systems will interfere with the nulling process.
2. Press MENU and advance to the “Manual Null” screen.
3. Press CHAN SEL to advance to the desired channel.
4. Rotate the “IN” knob to adjust the “RBAL” null value until the “Amplitude” is minimized.
5. Rotate the “OUT” knob to adjust the “CBAL” value until the “Amplitude” is minimized.
6. Repeat the “RBAL” and “CBAL” adjustment. The repeat process and order of adjustment of the process is important because
the “CBAL” adjustment is most effective when the “RBAL” is close to its absolute minimum.
7. Once the best null is achieved, turn the “IN” knob clockwise to add six to the “RBAL” value. For example, if the minimum
“RBAL” value is 123, adjust to 133.
8. Exit the Manual Null screen. Test for echo for at least 10 seconds. It will take up to 10 seconds for echo cancellation software
to achieve maximum efficiency.
If the echo is not acceptable, use the IN knob to adjust the “RBAL” null value up one and test again. If necessary, turn the
“RBAL” value down two and test again. Continue with this trial and error method until the echo is minimized.
Manual Null requires each channel to be nulled individually. Return to the Null Screen and press CHAN SEL to advance to
the next channel. Repeat for all channels.
Other Causes of Echo
Please be aware that echo can be cause by several sources. A type of echo referred to as acoustic echo can be caused by
another user’s headset, but is inaudible to that user. Have other users turn OFF their TALK button and determine if the echo
stops. Acoustic echo is minimized by software resident in each BeltStation. Acoustic echo may be mitigated by decreasing
the mic gain, sidetone or volume on the headset causing the echo. Occasionally, it is necessary to replace headsets that
continually cause unacceptable echo.
If a user removes his headset, the Mic may detect and repeat the sound from the earpiece. Whenever a headset is removed,
always turn OFF the Talk function.

Tempest®900 4-Channel Wireless Intercom System
2-Wire Wiring Schemes
Wiring schemes vary, and it is important to ensure that the cables are wired correctly for proper system operation. When
Tempest is configured for a particular manufacturer’s system, Tempest routes the signal to internal circuitry that conforms
to the requirements of that system. The 3-pin XLR connectors on the back of the Tempest BaseStation can have very
different characteristics depending on the setting of the slide switch, as can be seen in the table below.

Note for 2-Wire RTS Users: RTS TW (2-Wire) systems support two intercom channels on a single XLR cable. When connecting
an RTS TW system, only one cable is required for two intercom channels. When set to RTS mode, both of the 3-PIN XLR
connectors (2 male and 2 female) for channels A&B and C&D are paralleled together. RTS intercom channel 1 is placed on
Tempest intercom channel A, and RTS channel 2 is placed on channel B.; RTS intercom channel 1 is placed on channel C and
RTS channel 2 is placed on channel D.
Note for 2-Wire Clear-Com and Balanced (Audiocom) Users: For Clear-Com and Balanced 2-Wire intercoms, use the A, B, C,
and D male or female 3-pin (XLR-3M/F) connectors on the rear panel to connect up to four intercom channels. The male and
female connectors for each channel are loop-through connections and are the same point electrically. Each channel of a ClearCom or Balanced 2-Wire system requires one separate cable for connection to one Tempest channel.

Tempest®900 4-Channel Wireless Intercom System
Connecting Multiple BaseStations
Tempest BaseStations may be used together to form large wireless
systems, and may include external wired intercom systems. Intercom
audio for any or all channels can be linked across multiple BaseStations.
Audio from one BaseStation can be passed via a 2-Wire connection
to another BaseStation, if they are to share a single channel of audio.
Through this method, many complex combinations of intercom channels
can be achieved.
All RF devices have the potential to cause interference. Therefore,
Tempest offers a synchronization option, Accu-Sync™, that is designed
to minimize potential interference when using multiple BaseStations.
Accu-Sync is included with every Tempest BaseStation and uses the
Accu-Sync connections on the back of the BaseStation to synchronize
multiple BaseStations together. See the Accu-Sync section on for more
information on using Accu-Sync.
Tempest includes a Master Mode which provides required audio power when only Tempest BaseStations are linked without
external intercom. See the Master Mode section.
If intercom channels are connected across multiple BaseStations without connection to an
active 2-Wire intercom, one of the BaseStations must be placed into Master Mode.
A multi-base system will generally utilize Tempest Remote Transceivers to distribute the wireless signal, sometimes
extending the number of users by overlapping the wireless coverage area, and sometimes extending the wireless range
with the iSelect Roaming feature. In this application, always try to separate antennas by at least 10 feet whenever possible.
If multiple BaseStations are linked on a common audio channel, each BaseStation must be nulled separately. Null one BaseStation at a time.
A 4-Wire matrix intercom system may be configured to connect to multiple Tempest BaseStations so that all share the
same channels. Configure each BaseStation individually as described in 4-Wire (Matrix) Intercom Interface. The following
information relates to multiple BaseStation configurations without a matrix system.
57
Tempest®900 4-Channel Wireless Intercom System
Steps to Configure a Multiple BaseStation System
•
Locate and configure antennas to minimize RF interference.
•
Make Accu-Sync connections.
•
Make 2-Wire Connections.
•
Configure for the appropriate 2-Wire connections.
•
Null each BaseStation.
•
Adjust IN/OUT levels if necessary.
Audio Connections for Multiple BaseStations
When using multiple Tempest BaseStations, it is often desirable to share the same communication channels across some or
all BaseStations. To accomplish this, 2-Wire intercom connections must be made between the BaseStations.
It is advisable to configure the Accu-Sync option prior to making the audio connections.
There are two specific modes of operation when using this feature.
When an external hard wired intercom system is NOT present:
Tempest is designed to use any connected 2-Wire intercom system’s power source and termination to power the
BaseStation’s internal hybrid circuitry. When no hard wired system is present, Tempest uses a feature called Master
Mode to power and terminate this circuitry. Audio will not be shared among the BaseStations until one of the linked
BaseStations is set to Master Mode.
Master Mode only functions when there is no 2-Wire hard wired intercom system connected. If there is a hard wired
intercom connected to any channel of any of the shared Tempest BaseStations, Master Mode will automatically
disengage and only channels connected to the hard wired intercom system will continue to be shared.
In Master Mode, the number of Tempest BaseStations that can be linked is only limited by RF factors, which is
impacted by antenna location and other environmental factors. Widely distributed antennas may permit up to 5
BaseStations to be linked.
The 2-Wire Intercom Type Select Switch on the Tempest BaseStation front panel
must be set to “ClearCom” for Master Mode to function.
Using the 3-PIN XLR male or female connectors on the back of the BaseStation, connect the intercom channels of each
BaseStation that will share audio.
Set any one of the BaseStations to Master Mode “On.” It is only necessary to set one BaseStation to Master Mode.
Master Mode settings are found at the “Set Base as Master” screen under the “Multi-Base Settings” of the Main
Menu.
Once one BaseStation is in Master Mode, audio will be shared among all BaseStations that are connected to that
intercom channel. Lines must be nulled for proper operation.
58
Tempest®900 4-Channel Wireless Intercom System
When an external 2-Wire hard wired intercom system IS present:
Set the 2-Wire Intercom Type Select Switch to the proper type and select 2-Wire mode. Connect the hard wired
intercom to the BaseStation. In this configuration, each connected Tempest BaseStation intercom channel will receive
power and termination from the wired intercom system. The Tempest BaseStation functions as an additional wired
BeltStation from the perspective of the connected 2-Wire system.
Connect either male or female (male and female connectors are electrically identical) 3 pin XLR from the 2-Wire
intercom channel to be shared, to the BaseStation that will use the intercom channel. Loop to other BaseStations
as needed. Repeat for all channels to be shared. See the Wired Intercom Interface section in this manual for more
information about connecting to external wired intercom systems.
When using an external 2-Wire hard wired connection, only channels that are
connected to a wired intercom will be able to share audio between BaseStations.

Tempest®900 4-Channel Wireless Intercom System
Accu-Sync
Three BaseStations Accu-Synced
Accu-Sync provides a common timing signal between connected BaseStations. This signal ensures that transmission cycles
for all Accu-Synced BaseStations occur simultaneously. This synchronized transmission eliminates the negative RF effect
called desensing. See the following section, “Special RF Considerations for Multiple BaseStations,” for more information
on connecting multiple BaseStations.
When two or more Tempest BaseStations are to be operated in the same location, connecting the BaseStations via the
BaseSync connector on the back of the BaseStation, minimizes potential RF interference between BaseStations. The more
BaseStations there are in close proximity to each other, the more important it is to use Accu-Sync.
One BaseStation must always act as the sync source when using Accu-Sync. The sync source is any BaseStation that does
not have a BaseSync cable plugged into the BaseSync IN connector. Always ensure that one, and only one BaseStation has
an open (no connection) BaseSync IN connector.
When a BaseStation does not have a BaseSync cable plugged into the BaseSync IN connector, that BaseStation uses an
internally generated timing pulse to control its own transmission cycle.
When a BaseStation has a BaseSync cable plugged into the BaseSync IN connector, that BaseStation uses the external sync
signal (timing pulse) to control its transmission cycle.
The BaseSync cable is a DE-9F To DE-9M wired straight through on pins 1-5. The maximum distance a BaseSync cable can
be is 1,500 feet (457.2 m).
Never connect Accu-Sync cables between 2.4GHZ and 900MHz Tempest models.

Tempest®900 4-Channel Wireless Intercom System
Master Mode
Master Mode is a Tempest BaseStation function that allows multiple BaseStations to share audio without the presence of
an external hardwired intercom system.
It is necessary to use Master Mode when two or more BaseStations are connected with the 2-Wire interface, and no
external power source is present. Master Mode provides necessary system power to the 2-Wire hybrid circuiting in each
of the connected Tempest BaseStations. When an external 2-Wire intercom system is connected to Tempest, the external
2-Wire intercom system provides the required power and system termination and Master Mode is automatically disabled.
On the BaseStation that will be set to Master Mode, set the 2-Wire Intercom Type Select slide switches to the Clear-Com
position. Master Mode only works in Clear-Com mode. If “RTS” or “BAL” is selected, an attempt to set the BaseStation as
master will result in an error message. If the slide switch is changed from Clear-Com to RTS or BAL, Master Mode will turn
OFF, and it will be necessary to return to the “Multi-Base Setting” menu to re-enable Master Mode.
On slave BaseStations, set the slide switches to Clear-Com.
On each BaseStation, set the shared intercom channel(s) to the 2-Wire mode. Master Mode only works for channels
selected for 2-Wire connection.
Connect the appropriate intercom channel(s) of each BaseStation that will share audio using the 3-pin XLR male and female
connectors on the back of the BaseStation.
Complete all settings and connections before activating Master Mode. Set one BaseStation to Master Mode. Master Mode
settings are found at the “Set Base as Master” screen under the “Multi-Base Settings” main menu selection. It is only
possible to set one BaseStation as Master. The letter “M” will appear in the top line of the BaseStation display, to the right
of the BaseStation name, when Master Mode is active. An attempt to set a second BaseStation as master, will result in an
error message. It does not matter which BaseStation in a linked series is set to Master Mode. Note: previous versions of
Tempest firmware displayed Master Mode with the word “Master” in the top line.
Slave BaseStations – those not set as master – detect the master BaseStation as a Clear-Com connection.
An attempt to set a BaseStation to Master Mode while connected to a 2-Wire system, will result in an error message. If a
BaseStation has “Set Base As Master” first turned ON, and an external hard wired intercom system is connected later, the
Tempest BaseStation will turn OFF Master Mode.
The “Set Base As Master” setting will remain ON through a power cycle.

Tempest®900 4-Channel Wireless Intercom System
Special RF Considerations with Multiple BaseStations
Whenever multiple Tempest BaseStations are operated together in close proximity, special consideration must be taken to
ensure proper system operation and maximize operational range.
See the Antenna Location section of this manual for more information on antenna placement.
See the Antenna Configuration section of this manual for details about recommended cable type and other important
information about connecting your antennas to your Tempest BaseStation.
See the Accu-Sync section for more information on using synchronizing multiple Tempest BaseStations.
Up to 3-5 BaseStations may be used in simultaneous operation in close proximity to each other with proper synchronization
and antenna placement, under ideal conditions. Closely spaced antennas will cause adverse system performance and will
reduce operational range.
When two or more Tempest BaseStations are to be operated in the same location,
utilizing the Accu-Sync can significantly increase system performance and operational
range.
Never Sync between 2.4GHz and 900MHz Tempest models
Using Link Quality with Collocated Systems
Tempest provides a diagnostic tool to measure the link quality (LQ) between a BaseStation/Remote Transceiver and
corresponding BeltStations. LQ is a useful metric that can assist users in troubleshooting poor audio quality and system
performance. It can also be very helpful when collocating BaseStations and monitoring their performance. Users can view
LQ at the BaseStation or the BeltStation.
From the BaseStation, users can view the LQ for all corresponding BeltStations that are operating in Normal Mode. The
LQ for Shared BeltStations is not viewable at the BaseStation. To view, press Menu button, and select: Tech Menu>ENT
thru Warning!>Diagnostics>Reset Radio. From this screen you will see the LQ for all Normal BeltStations currently logged
into that BaseStation. Their corresponding slot number will be displayed above the LQ value. Note: The LQ value being
displayed on-screen is provided in real-time and utilizes the same data stream as the audio you hear; therefore, while
viewing LQ in this menu, audio quality between the BaseStation and BeltStations will likely be impacted. It is recommended
that this tool only be used during set-up and pre-production troubleshooting, and that you back out of this menu before
assessing system audio quality.
From the BeltStation, users can enable the LQ indicator by pressing the Menu button and selecting: Belt Settings>Tech
Menu>ENT thru Warning!>Diagnostics>Show Scan Debug. Once shown, the numerical LQ indicator will appear below the
battery indicator on the BeltStation’s main operational screen.
When collocating BaseStations, the LQ tool can be used to ensure each system is maintaining adequate link quality with
corresponding BeltStations and synchronization between systems is properly working. For more information on using Link
Quality when collocating systems, contact your Tempest Applications Engineer.
62
Tempest®900 4-Channel Wireless Intercom System
Maximum Number of Collocated Systems
Factors that affect the maximum number of systems that may be collocated in any given location include:
•
The existence and extent of harmful interference caused by in-band external radiators.
•
Number of BaseStations.
•
Number of BeltStations per BaseStation.
•
Whether or not synchronization is being employed.
•
Physical location of BaseStation antennas (either on BaseStations or on Transceivers).
•
Physical location of the BeltStations.
•
Specific hopping patterns selected.
•
Environment (wide open, reflective, through walls…).
Favorable system conditions include:
•
Locations with little or no interference from other 900MHz devices will provide the best opportunity for a large
number of collocated systems.
•
Proper use of synchronization resolves potential desensing issues.
•
Antennas of any particular system should be separated from every other system’s antennas by at least 10 feet (3
meters) for best collocated system performance.
•
BeltStations operating at similar distances from their respective BaseStation antennas provide the best opportunity
for satisfactory performance of a large number of collocated systems.
•
Network Number configuration should be set up to ensure each system’s hopping patterns are configured properly.
See the section on Network Number for more information.
•
Environment can play a big role in RF system performance. Every location is different and has its own unique set
of challenges. Generally speaking, locations with very long paths to very reflective surfaces tend to be the most
difficult for digital wireless communication systems due to the prevalence of inter-symbol interference.
With all factors listed above being favorable, three to five Tempest systems (each with five BeltStations in Normal Mode),
may be collocated with minimal or no user-perceived impact on system range or performance. It is highly recommended
to contact your Tempest Applications Engineer for assistance when collocating more than three BaseStations.
Adverse conditions will limit the number, effectiveness, and range of collocated systems in any given environment.

Tempest®900 4-Channel Wireless Intercom System
Troubleshooting
BaseStation
Limited RF range
BaseStation antennas or transceiver should be located as high as possible. Locating the BaseStation antennas above
head level is critical for optimizing performance and range.
•
Confirm that BaseStation antenna or transceiver are in an appropriate location and orientation.
•
Confirm that antennas or transceiver are not close to any metal structures or racks; locate the BaseStation and
BaseStation antenna or transceiver away from potentially interfering devices.
•
Ensure that antenna connections are securely made. If using coaxial cable to remotely locate antennas, the cable
must be a low loss 50 ohm coax, not more than 25 feet long.
•
If you are using multiple Tempest BaseStations in close proximity to each other, Accu-Sync should be used to
achieve maximum performance; in addition, set the Network Number for each BaseStation at least four numbers
apart.
Cannot hear one or more channels of hard wired intercom
•
Set the Front panel headset to monitor the intercom channel in question. Ensure that the Talk button is enabled
for the front panel headset. Turn the headset volume up to a comfortable listening level to hear your own voice
in your headset.

Tempest®900 4-Channel Wireless Intercom System
Glossary
2-Wire or TW: A type of intercom system characterized by audio signals transmitted and received on the same pair of wires
at the same time. The connector usually associated with 2-Wire or TW is a 3-pin XLR.
4-Wire: A type of intercom system characterized by audio signals transmitted on one pair of wires and received on a
different pair of wires.
Accu-Sync: Tempest Wireless technology that synchronizes transmission timing for up to 10 BaseStations to prevent
interference.
Auto-Null: A process that automatically optimizes the BaseStation 2-Wire, intercom interface hybrid to match the line
characteristics of the external 2-Wire system.
AUX IN: Inputs program or other audio sources into the Tempest BaseStation to one or more intercom channels. The
Auxiliary IN connector is a ¼” Tip/Ring/Sleeve jack that accepts a standard ¼” TRS plug.
AUX OUT: Outputs intercom audio from one or more intercom channels to an external system. The Auxiliary OUT connector
is a ¼” Tip/Ring/Sleeve jack that accepts a standard ¼” TRS plug.
Banner: The top line of the BaseStation display, with white-on-black lettering. Usually the banner is the title of a menu
screen.
Call Alert: A feature of intercom BeltStations intended to visually and/or audibly alert users to a communication transmission.
Channel: A duplex communication path to transmit and receive voice communication.
Desensing or receiver desensitization: Desensing occurs when a transmitter is operating in close, physical proximity to a
receiver, even if that transmitter is not on or near the receiver’s operating frequency.
Receiver desensitization occurs because receivers must maintain critical voltage and current levels throughout the frontend stages and a strong (i.e. physically close) transmitter can cause these levels to vary greatly. As these levels widely
fluctuate, the receiver performance will be greatly degraded. Increasing the physical distance between transmitter and
receiver will decrease desensing. The greater the frequency separation between the two, the less the receiver performance
will be affected.
Dual Listen: This BeltStation feature permits an operator to simultaneously listen to two channels.
Frequency Hopping, Spread Spectrum (FHSS): Radio technology that utilizes many frequencies in quick succession,
intended to minimize the probability of radio frequency interference.
79
Tempest®900 4-Channel Wireless Intercom System
Full Duplex: Simultaneous two-way conversations (i.e. telephone communication).
GPIO: General Purpose Input Output – a simple device control method.
Half Duplex: Two-way conversations, one-way at a time, such that one person cannot interrupt the other (i.e. walkie-talkie).
IFB: Interrupted Feedback, or Interrupted Fold-Back - The IFB system connects control room personnel such as the director,
or producer with the performers or “talent.” The performer wears a small earpiece that carries the program sound unless
the director or another member of the production team interrupts the program sound with special instructions through
the IFB.
iSelect On-Command Roaming: Permits the BeltStation user to select the BaseStation appropriate for the current location
or activity.
License Free: The 900 MHz band is approved for non-licensed use in virtually every country. It is the responsibility of the
user to ensure that the system is operated in accordance with local laws and regulations.
Lithium-polymer battery: A rechargeable battery that provides long lasting, reliable power, with a minimum of space and
weight, utilizing lithium based chemistry in a stable polymer.
Loop -Thru Connectors: Allow multiple BaseStations to share a common channel.
Master BaseStation: A Tempest BaseStation that powers the 2-Wire Hybrid circuitry in itself and up to 9 additional
BaseStations across the looped-thru shared channel. The Master BaseStation provides power and line termination.
Mix Minus Signal: A mix of all audio that the BeltStation user needs to hear, minus the audio coming from the BeltStation
itself.
Pairing: A programming process that allows a BaseStation and BeltStation to recognize each other.
Slot: One of five time intervals in the FHSS TDMA RF schema. Each BeltStation occupies a slot. Also, one of the five display
locations on the BaseStation LCD screen.
Stage Announce: A Tempest system feature that permits connection of the BaseStation to a public address system (PA),
and allows a BeltStation user to be heard through the PA. The option includes a relay that can be used to activate the PA
system.
Status Screen: Normal operational mode screen on the BaseStation or BeltStation LCD display.
T-Desk Software: Software, used to configure and monitor the Tempest Intercom System with a computer over a Local Area
Network.
