CHAPTER 1

Introduction

General Description

RTS Wireless BTR-30N UHF Synthesized Wireless Intercom system offers reliable, high-performance, high-fidelity fullduplex communications delivered with minimum spectrum usage.

The BTR-30N system includes the BTR-30N frequency agile base station and up to four (4) TR-30N or TR-32N frequency agile beltpacks operating in full-duplex communications. An almost unlimited number of beltpacks may be used with a base station if the beltpacks are in Push-To TX mode (half- duplex).

The BTR-30N system incorporates two (2) audio channel operation, permitting the beltpack operator to choose between two (2) separate audio channels of communication, with the base station tracking the beltpack selection. This allows the user the flexibility to create a party line and a private line within the same beltpack.

The BTR-30N system is perfectly suited for standalone operation and can also interface with other RTS wired intercom systems. In addition to the external intercom systems interfaces, the system provides connections for auxiliary balanced audio input and output, as well as wireless talk-around (WTA) and stage announce (SA) features.

The BTR-30N system has been designed for reliable, efficient operation. Operating in the VHF spectrum, 174 to 216 MHz, and the UHF spectrum 482 to 572 MHz range, the units perform reliable at line-of-sight distances of 300 feet. With available antenna systems from RTS, the effective operating range can be extended. The high-efficiency beltpacks provide between 8 and 11 hours of uninterrupted operation using NiMH rechargeable battery packs.

System Features

• Base RX and Beltpack TX is in the VHF range, greatly

reducing the system’s footprint in the congested UHF spectrum.

• Frequency-agile base station and beltpacks. No external

computer/device required to select frequencies.

• Backlit base-station LCD allows the user to easily monitor

the beltpack’s status and change base station frequencies.

• Squelch adjust on the BTR-30N, TR-30N, and TR-32N

beltpacks.

• Beltpack’s battery level displayed on the base station and in

beltpack’s menus.

• ClearScan function on base station and beltpack to

automatically find the best channels on which to operate.

• Full-duplex (simultaneous talk and listen) or Push-to-Tx

(half duplex) operation.

• Compatible with Audiocom (Telex), RTS TW and Clear-

Com wired intercoms.

• Two (2) independent channels of intercom audio with the

ability to operate party line and RTS matrix on the same intercom channel at the same time.

• WTA (Wireless Talk-Around) beltpack control. This feature

allows beltpacks to talk to each other, but their audio is lifted from any wired system connected to the base station.

• SA (Stage Announce) beltpack control. Allows the user to

direct their audio to a jack on the back of the base for P.A. systems or other external audio systems.

• Relay contact closure on the base when the SA button is

pressed.

• TR-32N features two (2) audio channel binaural operation in

either stereo or mono mode.

• TR-32N has a 1/8-inch (3.5mm) jack for auxiliary input

from another audio source, such as an IFB, iPod, or other similar device.

• Beltpack units contained in a weather and shock resistant die

cast magnesium case.

• Convenient IEC power connector on the base station so the

unit can plug directly to outlets. No in-line or wall plug power supply.

• Dark mode configurable on TR-30N and TR-32N beltpacks.

This shuts down all LEDs.

Distance between Antennas

The distance between the base station’s receive and transmit antennas is not adjustable when the antennas are connected directly on the back of the unit.

The antennas can be remotely moun An RTS coax assembly with remote antennas may be required. See “Accessory” section for ordering information.

NOTE: If

your base station is to be located in a shielded rack mount enclosure or other poor RF locations, you must remotely mount the antennas with coax assemblies. See “Accessories and Replacement Parts, for remote mounting hardware.

ted for a better signal path.

Antenna Placement

Proper antenna placement probably has the most effect on your RTS Wireless Intercom System’s overall performance. The following suggestions result in optimum performance.

Keep the distance between the base station and the beltpacks as short as possible. The greater the distance, the weaker the signal. Make sure the “signal paths” between the base station and beltpacks are unobstructed. You should be able to visibly locate the base station antennas at all times for best performance.

Proper placement of the beltpack can be critical. The antennas should be in the open. Bending the antennas up and placing the beltpack in a pocket, etc., reduces the system’s distance. The unit should be worn on the belt with both antennas vertical for best operating range and performance.

FIGURE 14. Distance Between Base Station and Beltpack

FIGURE 13. Proper Dressing of the Antenna

FIGURE 15. Keeping Site Clear to Antenna

Attempting to operate the wireless intercom system through or around walls, ceilings, metal objects, etc. reduces system range and performance.

FIGURE 16. Operating System Near Obstructions

IMPORTANT: DO NOT mount the base station antennas

on or next to: metal, such as beams; walls with metal studs; or equipment racks, etc. This also applies to antennas assembled directly to the Base Station. Mounting antennas near metal detunes the antennas, which can result in noise or loss of RF signal at the Base Station. See Figure 17.

FIGURE 17. Antenna Placement

Improving Reception and Increasing Range

Keeping the distance from the base station and beltpack as short and unobstructed as possible produces the most reliable antenna performance.

The base station is supplied with two (2) antennas. This provides satisfactory system performance in most applications. System range can be enhanced by remotely mounting the antennas. The antennas are ground plane independent, so a ground plane is not required for good performance.

Operation

BTR-30N

Operation

This section discusses the operation and features of the BTR30N base station, opening with base operation and quick system setup. It then discusses basic interfacing and setup of a base station, then ends with the connection of multiple base stations and discussion of the links between them.

Basic Operational Description

The BTR-30N narrow band wireless intercom system offers the most comprehensive, user-friendly, and versatile set of features available in wireless intercom systems anywhere in the world.

The base station accommodates up to four (4) full-duplex TR30N or TR-32N beltpacks, and can be used with an unlimited number of beltpacks in push-to-TX (half-duplex) operation. In push-to-TX mode, the unit provides a First On Latch Out feature which allows only one beltpack transmitter to be active at a time when multiple users are on a single base receive channel.

The base station, via the beltpacks or it’s local headset, allows communications with other wireless or wired users. The  2-wire and 4-wire intercoms may even be used at the same time. The wired audio interfaces to the base are:

• 2-Wire (Telex, RTS, Clear-Com) - 2 intercom channels

• 4-Wire - 2 audio channels

• Auxiliary (both input and output)

• SA (Stage Announce) (output)

• WTA (Wireless Talk-Around)/ 2 channels of private 

2-wire intercom among TR-30N and TR-32N beltpacks

• Local base station headset

The base station also features:

• A relay closure activated when the SA button is pressed at

any beltpack

• Four (4) easily accessible portable connect buttons on the

front panel. Use the buttons to turn off the audio from any of the four (4) base receivers while at the same time killing the talk/transmitter at the associated beltpack

• 36 engineering selected, intermodulation avoiding, factory-

defined groups

• The ability for users to enter frequencies of their own via 12

user-defined groups

System Quick Start

The following is a list to quickly get a base station and beltpacks operating.

1. Unpack the base.

2. Connect the power cord and antennas.

3. Connect the base to audio interfaces, such as: 2-wire, 

4-wire, SA, Auxiliary, or local headset.

4. Press and hold MENU while powering up the base station.

5. When the base station displays FACTORY SETUP, release

MENU.

6. Unpack the beltpacks.

7. Press MENU while powering up the beltpack(s).

8. Using the UP and DOWN arrow buttons, change the

beltpack channel to an unoccupied receive channel on the base station.

9. Press SET twice to set channel and group.

The base should now display the audio channel of the beltpack and a battery symbol appears shortly.

10. Plug a headset into each beltpack.

11. Adjust the microphone gain in the software menu so the

overmodulation light flashes only on some of the words at normal speech levels.

FIGURE 20. Loop-through of two base stations connected with

Telex/Audiocom or Clear-Com Intercoms

If multiple base stations are connected via 2 -wire intercom and no 2-wire power supply is involved to terminate the  2-wire, then termination plugs for the type of 2-wire system used must be at one end of each intercom line.

Since RTS-TW carries both channels of audio on one (1) cable, the four (4) intercom XLR connectors are connected in parallel when RTS is selected. Thus any one (1) of the four (4) intercom XLRs may be used for RTS input. Looping through of the audio, shown in Figure 21, may also be accomplished via any of the rear panel XLRs when in FTS mode. For a description of how to set up the 2-wire ports, refer to Intercom Settings in this section. The 2-wire intercom may be used at the same time as the 4-wire intercom.

The BTR-30N can connect to two (2) 4-wire audio intercom systems. These 8-pin modular jacks (RJ-45) are designated 4wire under intercom 1 and 2 titles on the rear panel. (See Figure 22). The jack’s pinout is shown in Figure 23.

FIGURE 23. Pinout of the 4-Wire Jack

The 4-wire intercom may be used at the same time as the  2-wire intercom.

Auxiliary Input/Output

The auxiliary input jack is a combination jack. It accepts either a 3-pin XLR or a 1/4” (6.3mm) plug. The expected input is a balanced line level input. Shown in Figure 24, the XLR plug and 1/4” plug are wired in parallel

FIGURE 24. Auxiliary Input XLR and 6.3mm Jack Pinouts

The auxiliary output jack is a 3-pin XLR jack. It produces a line level balanced output. Please refer to Figure 25.

FIGURE 25. Pinout of the Auxiliary Output Jack

The auxiliary input/output can be set to local, global, or off. (See the Aux Settings menu in the base). The output level is configured in the software.

• Local Aux Input - The input audio is only heard at the base

station’s local headset and beltpacks.

• Local Aux Output - The output audio is only heard at the

base station’s local headset and beltpacks.

• Global Aux Input - The input audio is heard at the base

station’s local headset and beltpacks and is placed on the 2wire/4-wire intercom.

• Global Aux Output - The output audio is heard at the base

station’s local headset and beltpacks and is placed on the 2wire/4-wire intercom.

• Off - the auxiliary input and output is off.

Base Station Link Jack

WTA 1 and WTA 2 in the BTR-30N are two (2) independent 2wire intercom channels. Up to 16 base stations may be connected together to share WTA audio. Do not confuse WTA audio with CAN bus data, as only eight (8) bases may be connected to share CAN bus data. Not only does the WTA Link cable pass both channels of WTA audio, it passes a logic level so the 1st base station in the chain is the only one providing a termination of the WTA intercom channels. Care must be taken to connect cables between base stations from the OUT of base one (1) to the IN of base two (2) and so forth. If the WTA link cable is passed from OUT to OUT or IN to IN, the WTA audio may terminate in multiple places and cause the WTA audio level to be greatly reduced.

The base station link jacks can interface with other base stations via two (2) different types of cables:

• Base Link Cable (BLC)

– Straight through cable. Passes CAN data, WTA

audio, and WTA termination signal.

• CAN Bus Termination Cable (CTC)

– Passes WTA audio and WTA termination signal, but

does not pass CAN data. Acts as a termination of the CAN networks on either side of it.

Detailed information on the pinout and operation of these cables

be found in “Connection of Multiple Base Stations with the

can Link Cables” on page 40.

Program Jack

This jack is only used for updating the internal software of the base station. It is typically used only by the manufacturer and service centers.

Connection of Multiple Base Stations with the Link Cables

This section discusses various configurations of multiple base stations using link cables. Multiple base stations may be

connected via standard 2-wire and 4-wire intercoms without additional link cables between them. They still transmit and receive intercom 1 and intercom 2 audio normally from the beltpacks.

FIGURE 56. Multiple base stations with only 2-wire intercom

channels 1 and 2 connected between them

However, by connecting multiple bases together via link cables, in addition to any 2-wire or 4-wire audio connections in use, the feature set of a single base becomes available to the whole system. This feature set also includes base stations that have their transmitters off in order to conserve RF spectrum.

These features are:

• (WTA) Wireless talk-around channels 1 and 2 shared

between base stations.

• First-On-Latch-Out of beltpacks extended to base stations

with their TXs off (when beltpacks are in push-to-transmit mode).

• Automatic beltpack TX power control extended to base

station with their TXs off.

• Automatic beltpack user ID assignment extending to base

stations with their TXs off.

• Beltpack TX and Talk shutdown via the base front panel

extended to base stations with their TXs off (when beltpacks are in push-to-transmit mode).

• Beltpack Talk shutdown via the base front panel extended to

base stations with their TXs off (when beltpacks are in pushto-talk mode).

BTR-30N, TR-30N, TR-32N Operation 41

Before presenting the configurations, we believe an explanation of RF data links plus master and servant base stations helps in understanding the multiple base arrangements.

Over-the-Air Data Links

There are two (2) RF data communication links within a BTR30N system.

• Beltpack-to-base conveys:

– Current button(s) selected

– Battery level

– Beltpack ID set confirmation

• Base-to-beltpack conveys

– Beltpack User ID

– Beltpack TX power level

– Beltpack TX and/or Talk Shutdown

– First-On-Latch-Out

FIGURE 57. Base-To-Beltpack and Beltpack-To-Base RF Data Links

These two (2) data paths are intact when there is only one (1) base communicating to beltpacks. They are also intact when many base stations on different TX and RX frequencies are communicating to their beltpacks.

However, in a system with one (1) or more base stations with their transmitters off, the base-to-beltpack data link is lost for those beltpacks

A wired data link is needed to communicate the base-tobeltpack information from the base stations with their transmitters off to the base with its transmitters on.

Master and Servant Base Stations

A master base station is one that the user has set its base number to 01(Master) and has its transmitters on. A master base conveys base-to-beltpack data to its beltpacks and via a base station link cable, relays the base-to-beltpack data from

base stations that have their base transmitters off. A master may support up to seven (7) additional base stations with their transmitters off.

IMPORTANT: There can be only one (1) master base

station in a network of base stations.

A master base automatically sets a 09 (default) base to a unique 02 to 08 servant number. If a base is already a servant the master leaves it at that same number.

FIGURE 59. Status screen of a master designated base

station

NOTE: Any time base

stations are changed to be a master base station, it must be power cycled for the change to take affect.

A servant base station is one that has its transmitters

off and is connected to a master base. Since servant base stations have their transmitters off, base-to-beltpack information can only get to beltpacks via link cables connected to a master base station.

FIGURE 61. How to get to the master/servant

selection screen

From the factory, base station are set to base number 09. This is an unassigned base. The base

can be left as 09 if not in a linked

system. It works as normal with all features.

If the unassigned base is connected to a master base station, the master automatically assign a valid, unique, servant ID to it the first time the networked system is powered-up.

The master base must always power-up after the servant bases in order to detect servant units to control. If all the units are on a common power strip, this is controlled by a built in delay on master base station. The master base station always boots slower than servant units.

CAN bus

A CAN (Controlled Area Network) bus is the data protocol used over the BTR-30N’s base station link cable. This balanced protocol is a robust standard used the world over in high noise, extreme environments. It requires the use of 120 Ohm terminators at the beginning and end of a CAN bus network.

Base Station Link Configurations

Multiple base station networks may be connected in different ways. Using the rear panel base station link jacks, a user has three (3) different connection options.

These options are:

Wireless Talk-Around Audio Only

These base stations are connected to share WTA channel 1 and WTA channel 2 audio but do not share the CAN bus data.

Link Overview

WTA 1 and WTA 2 in the BTR-30N are two (2) independent 2wire

intercom channels. The WTA intercom channels are very similar to AudioCom types of intercom channels except they are dry and are meant to only pass audio between BTR-30N base stations.

Up to 16 base stations may be connected together with base link cables (BLC) The BLC passes both channels of WTA audio. It also passes a logic level so the 1st base station in the chain is the only one that provides a termination of the WTA intercom channels. This pin is labeled “TERM CONT” on the RJ-45 plug pinouts in this section.

Care must be taken to connect cables between base stations from the OUT of base one (1) to the IN of base two (2) and so forth, unit to unit.

depending on cable length and conductor size.

If the WTA link cable passes from OUT to OUT or IN to IN, the WTA audio terminates in multiple places and causes the WTA audio levels to be greatly reduced/distorted.

FIGURE 64. BLC (Base Link Cable) and pin functions. 

(Not Supplied)

If base stations are farther apart than the 12” (30.48cm) BLC, then 568-A or 568-B Ethernet cables of CAT-5E or above may be used to connect base stations up to 300 feet apart. These Ethernet cables contain four (4) twisted pairs like the BLC cable.

FIGURE 65. Multiple base stations connected via 2-wire

audio cable and WTA through via BLCs

BTR-30N, TR-30N, TR-32N Operation 47

Do not set base stations to the base number 01 (Master), because CAN bus is connected to the other base stations with a BLC, as seen in Figure 65. If there are no masters on the CAN bus system, there is no activity on the CAN bus line and no need for terminations.

IMPORTANT: The master base must always 

power-up after the servant bases 

in order to detect servant units to control. If all units are on a common power strip, this is controlled by a



built in delay on the master base station. The master base station always boots slower than servant units.

WTA and a SINGLE CAN Bus Network

These base stations connect via 2-wire and/or 4-wire audio links and also by the Base Link Cable (BLC). The BLC cable passes WTA audio and CAN bus data information. The CAN bus connected base stations form a Network.

Link Overview

There are two (2) RF data communication links with a BTR30N system. The beltpack-to-base links convey information such as current button(s) selected, battery level, etc. The baseto-beltpack links convey beltpack user ID, beltpack TX shutdown, beltpack talk shutdown, and other information.

The two (2) paths are intact when there is only one (1) base communicating to beltpacks and when many base stations on different TX and RX frequencies communicate to the beltpacks. However, when one (1) or more base stations with their transmitters off are connected to a base station with its transmitters on, the base-to-beltpack data link is lost for those beltpacks.

NOTE: This may be 2-wire intercom. This could also be 4-

wire intercom via a matrix type wired system.

4. Connect the Base Link Cable between base stations.

NOTE: Verify the OUT of the first base station connects to

the IN of second base station and follow the same connection pattern forward.

As each beltpack is set to its group and channel, an hourglass symbol appears on the base display in the location normally occupied by the battery symbol. A beltpack is assigned an ID number by the base in this time. Finally, a normal battery symbol is displayed, indicated the beltpack has been assigned its ID number.

Care must be taken to connect cables between base stations from the Out of base one (1) to the IN of base two (2) and so forth.If the WTA link cable is passed from OUT to OUT or IN to IN, the WTA audio terminates in multiple places and causes the WTA levels to be greatly reduced/distorted.

Setting Beltpack ID

Several functions require the beltpack to know which base and channel it is associated with.

1. Auto Power Setting: The beltpack reduces its TX power

when close to the base. Beltpack transmit power must be set to Auto.

2. Portable Station Deselect: The base can disable the TALK

button of a beltpack. This shuts off the mic in PTT mode and turns off the transmitter in PT TR mode.

3. First-On-Latch-Out: This locks a base receive channel so

only one beltpack can transmit on the frequency at a time. A beltpack user attempting to talk on top of another beltpack on the same frequency hears a double beep in their headset.

A beltpack tries to establish its ID auto channel changes. The base must be on for this to work.

To check or set beltpack ID manually, do the following:

1. Press and hold UP for two (2) seconds. 

The LCD displays ID Base# - Receiver#.

For example: ID 1-3 means Base 1, Receiver 3.

If the LCD displ

There are 48 groups in a BTR-30N system. The 48 groups are divided up into 36 factory-defined groups and 12 user-defined groups. A group referenced to a base station is comprised of two TX channels and up to 12 RX channels.

User-defined groups are bl enter their own frequencies.

Factory-defined groups are composed of frequencies that cannot be modified by the user. The 36 groups are composed of the following:

Nine (9) Triplet Groups

ank initially and allow the user to

– Groups 1a to 9c

Nine (9) Single Groups

– Groups 10-18

The factory groups are organized i flexibility to the user on selecting frequencies. A groups is composed of intermodulation free frequencies. The triplet groups may be used together for up to three (3) systems that are intermodulation coordinated. For example, three intermodulation coordinated systems may be set up by using the following groups and channels:

n different ways to provide

• System A = Group 1a, channels: 1, 2, 3, 4

• System B = Groups 1b, channels: 5, 6, 7, 8

• System C = Group 1c, channels: 9, 10, 11, 12

A group also contains frequencies within different combinations of the TV channels. The user can select a group clear of broadcast Tv channels in the area by selecting a group(s) not using those channels.

Figure 81 indicates how the factory-defined groups used the three (3) TV channels for TX and three (3) TV channels for receive. These plans are based upon US broadcast TV channels. A darkened TV channel indicates the group has frequencies in the channel. The white TV channel indicates the group has no frequencies in the channel. For example, Group 1A uses at least one (1) frequency from each of the three (3) TV channels for RX and only the 1st TV channel for TX. However, group 18 uses only the 3rd TV channel for TX and RX.

Troubleshooting

PROBLEM SOLUTION

DISTORTION - System’s audio quality seems distorted at

medium to high input levels

HISS - System seems to produce a hiss which is undesirable.

LOW OUTPUT - System produces a low output level. Check the gain setting on both the beltpacks and the base.

FEEDBACK - Moving around are of use produces squeal

or howl in various locations using the ext. speakers.

DROPUOUTS - When moving around the area of use there seem to be locations where the signal swooshes or completely disappears.

INTERFERENCE - System picks up signals other than wireless intercoms.

NO AUDIO - from base of beltpack headsets. Check transmitter setting on base and beltpack. Check talk

BASE and BELTPACK’S Frequencies Don’t Match - In

the display frequencies screen of the base and the menu of the beltpack the frequencies don’t match.

Reduce microphone gain by adjusting microphone gain control in software.

Check the gain setting on all beltpacks and the base. They may be too low or too high. Check to make sure you are still well within range of the base station.

They may be too low.

Reduce the gain settings on both the beltpacks and the base. They may be too high. If in 2-wire mode, the intercom channel you are on may be unloaded.

Make sure both antennas on the base and beltpack are connected and follow the location suggestions. Change the location of the base unit and antennas or avoid the bad areas with the remote beltpacks.

Make sure the beltpack(s) are on. If there are any unused receivers at the base, turn the audio off from those receivers by deselecting the appropriate Portable Station Connect button.

If problems persist with the beltpack on, you will probably need to change the group. Make sure the base and beltpack match after any Group/Channel change.

LED to ensure it is on. Make sure beltpack batteries are OK.

Ensure the units are on the correct Group and Channels.

IMPORTANT: Reread the sections of this manual to make sure you completed system set-up properly.

If you are unable to solve the problem, assistance

contact the dealer from whom you purchased the system for

Battery Information

Improper battery selection, use, installation, and care are the cause of numerous wireless systems failures.

Alkaline Batteries: Alkaline batteries such as Eveready’s ENERGIZER and ENERGIZER INDUSTRIAL provide the most reliable operation in wireless transceivers.

The use of low cost carbon-zinc batteries is NOT recommended.

Nickel-Metal Hydride Batteries: These batteries can save you

money in the long run, as they can be recharged. Typical battery life is a little less than the length of time alkaline batteries last.

Battery Warnings

• Do not place alkaline battery packs in any battery charger.

Severe charger and battery pack damage may occur!

• Batteries that have been dropped, or otherwise damaged,

should not be used and should be discarded properly. Dropping batteries can crack the internal casing causing leakage or rupture resulting in personal injury or property damage!

• Insert batteries properly, with the plus (+) and minus (-)

terminals aligned correctly!

• Do not mix old and new batteries, batteries of different

types, or batteries of different brands. This can cause leakage or rupture, resulting in personal injury or property damage!

• Immediately remove exhausted batteries from the battery

pack and dispose of properly.

• Replace all used batteries in your device at the same time.

• Do not put batteries or battery-powered devices in very

warm places. Extreme temperatures reduce battery performance and may also lead to leakage.

• Use only high quality AA sized alkaline batteries in the

battery packs.

• When not in use, disconnect battery pack, remove and store

batteries in a cool, dry place at normal room temperature until ready to use.

• Keep battery contact surfaces clean by gently rubbing with a

clean pencil eraser or cloth.

Battery Life

TR-30N

Alkaline, 11-13 hours typical

Nickel-Metal Hybrid, 10-12 hours typical

TR-32N

Alkaline, 8-10 hours typical

Nickel-Metal Hybrid, 7-9 hours typical

Energizer® is a registered trademark of Union Carbide Corporation

Cold Temperatures and Batteries

The battery life times listed in this section are at room temperature. Alkaline and Nickel-Metal Hydride battery service hours fall off significantly at low temperature due to battery chemistry. Alkaline batteries typically have less than half their room temperature service life if used at freezing 32° F (0° C). If you use Alkaline and Nickel-Metal Hybrid batteries at low temperatures, you need to change them more often.

Another solution is using Lithium AA cells if beltpacks are to be used in very cold temperatures. Lithium batteries, like the Energizer ultimate Lithium AA cells, are excellent batteries for cold temperatures. At 15° F (-9° C), Lithium AA cells will last about seven (7) times longer than Alkaline batteries. This equates to two (2) hours for Alkaline vs. 14 hours for Lithium. However, the trade off is Lithium batteries cost more and are less environmentally-friendly than Alkaline batteries.
