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

The top panel provides on/off/volume
control, channel select buttons and lights,
talk button and battery status light.

Operation

light will activate indicating the unit is
running.

Once a BTR-240 or BTR-24 is running, the TR­240 may be switched on at anytime. The TR­240 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

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

pressed.

6. Use as normal.

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

1.2 “Wired” Mode

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 Wireless” Mode

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.
