General Description

Telex RadioCom™ BTR-80N UHF Synthesized Wireless In- tercom system offers reliable, high-performance, high-fidelity full-duplex communications delivered with minimum spec- trum usage.

The BTR-80N system includes the BTR-80N frequency agile base station, working with up to four TR-80N or TR-82N fre- quency agile beltpacks operating in full-duplex communica- tions. 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-80N system incorporates two audio channel opera- tion, permitting the beltpack operator to choose between two separate audio channels of communication, with the base sta- tion 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-80N system is perfectly suited for stand-alone oper- ation and can also interface with Audiocom® (Telex), RTS® TW, Clear-Com®, as well as RTS®, Matrix systems and other 4-wire intercom systems. In addition to the external intercom systems interfaces listed above, the system provides connec- tions for auxiliary balanced audio input and output, as well as wireless talk-around (WTA) and stage announce (SA) fea- tures.

The RadioCom™ BTR-80N system has been designed for re- liable, efficient operation. Operating in the 482 to 722 MHz range the units operate reliably at line-of-sight distances of 1,000 feet. With available antenna systems from Telex, the ef- fective operating range can be extended. The high-efficiency beltpacks provide between 8 and 11 hours of uninterrupted op- eration using NiMH rechargeable battery packs.

Attaching Transmit 1/2-Wave Antenna

Attach the receive 1/2-wave antenna to the antenna input re- ceptacle labeled “Receive” on the left side of the rear panel. The antenna should be vertically aligned.

Distance between Antennas

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

The antennas can be remotely mounted for a better signal path. A Telex coax assembly with remote antennas may be re- quired. 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 location, you must remotely mount the 1/2-wave antennas with coax assemblies. See "Ac- cessories and Replacement Parts" section for remote mounting hardware.

Antenna Placement

Proper antenna placement probably has the most effect on your TELEX Wireless Intercom System’s overall perfor- mance. The following suggestions will result in optimum per- formance.

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., will reduce system distance.

It is suggested that the unit be worn on the belt with both an- tennas vertical for best operating range and performance.

Antenna Polarization

The Telex Wireless Intercom System is “Vertically Polarized”.

This means both the transmitting and receiving antennas

should operate in the vertical position.

Proper Dressing of the Antennas

5-2

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 perfor- mance.

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

DO NOT - mount the base station 1/2-wave antennas on, or next to metal, such as beams, walls with metal studs, equip- ment racks, etc. This also applies to the antennas when assem- bled directly to the Base Station. This will “detune” the antennas which can result in noise or loss of RF signal at the Base Station, see Figure 5-8.

Improving Reception and Increasing

Range

Keeping the distance from the base station and beltpack as short, and unobstructed as possible will produce the most reli- able performance.

The base station is supplied with two antennas. This should provide satisfactory system performance in most applications. System range can be enhanced by remotely mounting the 1/2-wave antennas. The ½ wave antennas are ground plane in- dependent, so a ground plane is not required for good perfor- mance.

BTR-80N Operation

BTR-80N Operation

This Section will discuss the operation and features of the BTR-80N base station. The section will open with the base operation and quick system setup of a BTR-80N system. It will then discuss basic interfacing and setup of a base station. Finally it will end with the connection of multiple base stations and discussion of the links between them.

Basic Operational Description

The BTR-80N 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 can accommodate up to 4 full duplex TR-80N or TR-82N beltpacks. A base may 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. This feature allows only one beltpack transmitter 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 communication 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 a private 2-wire intercom just among TR-80N and TR-82N

beltpacks.

for the user to enter frequencies of their own via 12 user de-

fined groups.

System Quick Start

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

1.Unpack the base and connect the power cord and antennas.

2.Connect base to audio interfaces. For example; 2-wire, 4-wire, SA, Auxiliary local headset.

3.Press and hold [MENU] as powering-up the base station. Release button when base station displays "...FACTORY SETUP...".

4.Press [MENU] as powering-up the beltpacks(s)

5.Use the [UP] and [DOWN] arrow button to change the channel to an unoccupied receive channel on the base station. Then press [SET] twice to set channel and group.

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

7.Plug a headset into each beltpack. Adjust the software menu for microphone gain so the overmodulation light flashes only on some of the words at normal speech levels.

•Local base station headset

The base also has a relay closure available that is activated when the SA is pressed at any beltpack. There are 4 easily accessible portable connect buttons on the front panel. The buttons may be used to turn off the audio from any of the four base receivers while at the same time killing the talk/transmitter at the associated beltpack.

The base station comes with 36 engineering selected, intermodulation-avoiding groups of channels, plus the ability

Pin Outs of RTS, Telex and Clear-Com Intercoms

The base station does not require "wet" intercom lines for op- eration. Wet intercom lines are those with D.C. voltages on them for powering 2-wire devices. The base will loop thru wet intercom lines with currents up to 2 Amps.

Warning! Do not loop thru more than 2 Amps of current.

Damage to the base station may result.

Figure 6-3

Loop-thru of Two Base Stations connected with

Telex/Audiocom or Clear-Com Intercoms

Since RTS-TW carries both channels of audio on one cable, the four intercom XLR connectors are connected in parallel when RTS is selected. Thus any one of the four intercom XLRs may be used for RTS input. As shown in Figure 6-4, looping thru of the audio may also be accomplished via any of the rear panel XLRs when in RTS mode. For a description of how to set up the 2-wire ports refer to "Intercom Settings" in this section.

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 settable in 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 from the local headset and beltpacks.

•Global Aux Input = The input audio is heard at the base station's local headset, beltpacks and placed on the

2-wire/ 4-wire intercom.

•Global Aux Output = The output audio is from the base station's local headset, beltpacks and 2-wire/4-wire

intercom.

•Off = The auxiliary input and output is off.
