CHAPTER 1 Introduction General Description System Features RTS Wireless BTR-30N UHF Synthesized Wireless Intercom system offers reliable, high-performance, high-fidelity fullduplex communications delivered with minimum spectrum usage. • Base RX and Beltpack TX is in the VHF range, greatly 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.
10 Introduction BTR-30N, TR-30N, TR-32N Controls and Connections BTR-30N – Front Panel FIGURE 1. BTR-30N - Front Panel 1. Power Switch - Do not power up a base station within three (3) seconds of the unit being turned off. Voltages within the unit need to drop below a threshold before being repowered. If powered-up in less than three (3) seconds, the unit may boot as the wrong frequency band. Even with the unit powered down via the power switch, some circuits within the base remain energized.

CHAPTER 2 Installation Unpacking Unpack your RTS System. Below are the items that should come with your base station and each beltpack. Contact the shipper or your dealer immediately if anything is damaged or missing.
20 Installation BTR-30N, TR-30N, TR-32N Antenna Connection The base station is supplied with two (2) antennas. One 1/2wave antenna for UHF transmit and one end-fed 1/2-wave for VHF receive. The antennas have TNC male connectors. The frequency range of the antennas should match the receiver and transmitter of the base station. Match the color code on the antenna with the color code on the base station.
BTR-30N, TR-30N, TR-32N 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. Installation 21 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.
22 Installation BTR-30N, TR-30N, TR-32N 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.
BTR-30N, TR-30N, TR-32N FIGURE 17. Installation 23 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.

CHAPTER 3 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.
26 Operation BTR-30N, TR-30N, TR-32N FIGURE 18. BTR-30N Rear View Transmit and Receive Antennas The TNC transmit jack and receiver jack are both labeled on the rear of the unit. The base station comes with two (2) antennas. Always match the color dot on the rear panel of the base station with the colored band on the antenna. The base station does not require wet intercom lines for operation. Wet intercom lines are those with D.C. voltages on them for powering 2-wire devices.
BTR-30N, TR-30N, TR-32N Loop-through of two base stations connected with Telex/Audiocom or Clear-Com Intercoms FIGURE 20. 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.
28 Operation FIGURE 22. BTR-30N, TR-30N, TR-32N BTR-30N Rear View 4-Wire Intercom Ports 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 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 23.
