RTS Model TR-240 Beltpack

Owners / Users Manual

(Preliminary Information)

General Description

The RTS model TR-240 beltpack transceiver is intended for use as a wireless full-duplex intercom radio to be worn on a belt. Multiple TR-240 beltpacks can be used with a BTR-240 base station transceiver or a

BTR-24 access point to communicate with each other over-the-air.

The TR-240 uses the IEEE 802.11b technology to transmit / receive within one channel of the 1 – 11 (2.412 to 2.462 GHz) allowable channels of the 2.4 GHz ISM band. Its operation is license free.

The typical line-of-sight distances for the system may be 300 feet.

The transmit and receive antennas are internal to the beltpack so the unit has a smaller profile. The outer case also provides extra protection against possible damage to the antennas.

The TR-240 is powered via an internal Li-

Ion battery that will provide up to 8 hours of run time at room temperature.

Operation

Once a BTR-240 or BTR-24 is running, the TR-

240 may be switched on at anytime. The TR-

240 has key features that can be set during boot and after the unit has booted. These settings include the following:

• Mode of Operation

• Local Headset Configuration

1 Setting the Beltpack Mode

The TR-240 has three different and selectable modes of operation: “wireless” mode, “wired” mode, and “master wireless” mode. The normal mode is “wireless”.

A TR-240 beltpack is configured to boot in one of these modes by holding a specific button sequence while the unit is booting.

NOTE : Once the TR-240 mode is set, it will continue to boot in that mode until different mode is selected on startup.

1.1 “Wireless” (Normal) Mode

In this configuration, a base station or access point provides wireless coverage over the area in which the beltpacks will be used.

1.

Ensure that a BTR-240 base station or

BTR-24 access point is configured and running the in the desired coverage area of use.

2.

Turn on the TR-240. The battery light will turn green immediately indicating power.

3.

To place the TR-240 in “wireless” mode, if not already set, press and hold the

<Talk> button as the beltpack boots.

4.

After 20 seconds boot time, a voice prompt “wireless” will be heard in the headphone and the “Channel 1” button

TR-240 Users Manual - Preliminary

Rev D – 3 / 09 / 2011 light will activate indicating the unit is running.

5.

Release the <Talk> button if it is being pressed.

6.

Use as normal.

NOTE: In “wireless” mode, the wired Ethernet port is disabled.

Beltpacks are directly connected to each other via an Ethernet cable or through a building’s

Ethernet infrastructure. In “wired” mode, the wireless transmitter is disabled.

1.

Connect the TR-240 to an existing wired network or computer using a standard

Ethernet cable.

2.

Turn on the beltpack. The battery light will turn green immediately indicating power.

3.

To place the TR-240 in “wired” mode, if not already set, press and hold the <2>

(blue) button as the beltpack boots.

4.

After 20 seconds boot time, a voice prompt “wired” will be heard in the headphone, followed by the current software version.

5.

Release the <2> button if it is being pressed.

6.

Use as normal.

NOTE: In “wired” mode, the wireless transmitter is disabled.

1.3 “Master

A beltpack can be configured to act as a base station and eliminate the need to have an actual

BTR-240 base station or BTR-24 access point.

This “master” beltpack may still be used for audio just as a normal beltpack. In “master wireless” mode, the wired Ethernet port is disabled.

1.

Turn on the TR-240. The battery light will turn green immediately indicating power.

2.

To place the TR-240 in “master wireless” mode, if not already set, press and hold the <1> (green) button as the beltpack boots.

3.

After 20 seconds boot time, a voice prompt “master wireless” will be heard in the headphone, followed by the current RF channel (“channel xx”) of operation.

4.

Release the <1> button after the voice prompt indicates the RF channel.

5.

Use as normal.

NOTE: In “master wireless” mode, the wired

Ethernet port is disabled.

1.3.1 Setting the RF Channel

For a beltpack that is in “master wireless” mode, the RF channel of operation can be selected.

1.

Boot the TR-240 in “master wireless” mode by holding the <1> (green) button as the beltpack boots.

2.

Once the TR-240 has successfully booted, the unit will give voice prompts indicating “master wireless” and

“channel xx”.

3.

To change the RF channel of operation, continue to press the <1> button after the

RF channel has been indicated by the voice prompt. Another voice prompt

“RF Selection” will be heard to notify the user that the RF channel can now be changed.

4.

After the “RF Selection” voice prompt is heard, release all the buttons, and four options can be made. a.

Press the <1> button to decrease the RF channel of operation. b.

Press the <2> button to increase the RF channel of operation.

TR-240 Users Manual - Preliminary

Rev D – 3 / 09 / 2011 c.

Press the <Talk> button to perform a ClearScan ™ and select the clearest RF channel that for the current environment. d.

Press <1> + <2> simultaneously to make the selection and exit the

RF selection mode.

5. Once the master beltpack is configured and running, the other TR-240 beltpacks should be booted in “wireless” (normal)

2 mode.

NOTE : Once an RF channel has been selected, the unit will continue to boot and operate on that channel until the user sets it to a different channel.

Local Headset Configuration

There are several ways to configure the local headset at the base station front panel. Settings for the local headset include the following:

• Talk Button

• Channel Select Button

• Local Headset Volume

• Microphone and Sidetone Levels

Button

Pressing the <Talk> button on the front panel will enable and disable the audio path from the headset microphone. The green talk light will be illuminated when the microphone path is enabled. The green talk light will blink when the microphone path is disabled.

There are two different modes that dictate how the <Talk> button behaves when pressed: Pushto-Latch and Momentary. The talk mode can be toggled by pressing the <1> + <2> + <Talk> buttons simultaneously for approx. 3 seconds followed by a corresponding voice prompt.

2.1.1

Push-to-Latch (default)

Tap the <Talk> button for less than ½ second and the microphone path will latch and remain enabled. Tap the <Talk> button again to turn off the latch and disable the microphone path.

Press and hold the <Talk> button for longer than ½ second and the microphone path will continue to be enabled while the <Talk> button is pressed. The microphone path will be disabled when the <Talk> button is released.

2.1.2

Momentary

The microphone path will not latch when the

<Talk> button is tapped. The microphone path will only be activated when the <Talk> button is pressed.

2.2 Channel Select Button

Pressing the <1> button will activate the audio from Intercom Channel 1 in the local headset.

Pressing the <2> button will activate the audio from Intercom Channel 2 in the local headset.

Pressing the <1> + <2> buttons simultaneously will activate both Intercom Channel 1 and

Channel 2 in the local headset.

The LEDs above each intercom channel button will be illuminated when active. If the microphone path is disabled from the talk button, then the active intercom channel LEDs will blink.

2.3 Local Headset Volume

The local headset volume can be controlled from the front panel by turning the <Volume> knob clockwise and counterclockwise to increase and decrease the volume, respectively.
