SECTION 1: INTRODUCTION

LAON Technology („LAON‟) is a leading-edge technology developer and innovative solutions provider in Digital Wireless Audio
Communications and Wireless Intercom Systems.
LOAN‟s digital wireless Intercom System, LT250 operates in license-free 5GHz UNII band securing high performance wireless
coverage and scalability. And LAON‟s technologies such as non-compressed audio transmissions, triple diversity (3D), noise
cancelling and automatic interference avoidance realized to enable our high standard intercom users to experience break-up free
audio communications. LT250 provides a full flexibility on grouping allowing up to three (3) communication group channels to be
allocated with up to nine (9) full-duplex audio paths – eight (8) channels for Belt Pack and 1 (one) channel for Base Station. It also
maintains the audio clarity high in quality even in noisy environments and guarantees private and secured communications by AES
256bit Level-3 encryption. More details to be followed;

Up to 32 Belt Packs can be paired up with each Base Station in the normal mode and additional 96 Belt Packs can be paired up
under the shared mode. Those Belt Packs under the shared mode operate only in „Push-to-Talk‟ mode. 32 Belt Packs with which
have been paired up with Base Station in the normal mode can be monitored, and additional 96 Belt Packs with which have been
paired up in the shared mode cannot be monitored at the Base Station.

Up to three (3) communication groups, single or multiple, can be allocated and configured flexibly to the Base Station, Belt Pack
and Auxiliary input/output. The communication group allocation to Belt Packs, Auxiliary input/output and the Base Station itself can
be set each by the Base Station operator using the Base Station menus.
As shown from the figure, „Communication group allocation‟ of the System Usage Example below, for instance, you may allocate
only one group to Belt Pack # 1 (Group # 1 for BP1), two groups to Belt Pack # 3 (Group # 1 & 2 for BP3) and all the three (3)
groups to Base Station (Group # 1, 2 & 3 for Base Station).
Belt Packs and other devices in the same communication group can talk with others in the designated group. The selected
communication group is displayed on the NORMAL menu of the Belt Pack as “1” through “3”.
Base Station and Auxiliary devices can communicate at the same time with all the groups allocated up to three (3). The selected
communication group is displayed on the NORMAL menu of the Base Station as “1” through “3” and “A”.

Remote Base Station (RBS) can be connected to the Base Station through LAN, composing customized and continuous coverage,
and enabling automatic roaming between coverage zones. The Remote Base Station supports the communications with Belt Packs
in remote area from the Base Station and shares up to nine (9) full duplex audio paths with the Base Station within the coverage
area. Standard CAT-5 cable is used to connect the Remote Base Station either directly to the LAN port on the rear panel of the
Base Station, or via network switch. Remote Base Station can be powered by local electricity or network switching devices which
has the Power-over-Ethernet (POE) function. Due to network traffic delay, audio breakups might occur in communications between
Belt Packs in the Remote Base Station coverage, or in communications with Belt Packs which are connected to the Base Station. In
that case, it is recommended to compose the network exclusively.

OLED displays on the front panel of the Base Station and Belt Pack are for setting up operations and monitoring. The Base Station
can monitor connectivity status among the Base Station, Remote Base Station and Belt Packs. Moreover, the Base Station can
monitor each Belt Pack‟s Received Signal Strength Indication (RSSI) level, battery level and microphone gain.

The USB port on the rear panel of the Base Station is supposed to be used for communication with PC to exchange data and
update programs.

5

Audio latency is one of the most critical factors in all digital wireless system. LT250 realized low latency, less than 23msec for total
one-way system latency from the Belt Pack to the Base Station.

Up to five Belt Packs and two Belt Pack Batteries can be charged at the same time by Battery Charger (BATCHG125). You can use
rechargeable Battery Pack (BAT50) or two AA 1.5V alkaline batteries in the Belt Pack.

LT250 Digital Wireless Intercom System powered by LAON‟s leading edge technology provides not only high quality audio
performance but reliable coverage, diverse functions and flexibilities.

BS250 BASE STATION SETUP

Following descriptions are stand-alone LT250 system configuration. Using additional devices such as Remote Base Station,
auxiliary input/outputs and 8ohm speaker will be explained later.

Step 1: Put two enclosed antennas to the antenna connectors (#1 and #5) on the rear panel of the Base Station. Turn the sleeve on

each of the antenna connectors clockwise to tighten them, and ensure that the antennas are connected firmly.

NOTE 1: These two antennas must be positioned vertically and be folded completely as 90 degree. Otherwise, it will be

caused to weaken the signal.

NOTE 2: While attaching the antennas directly to the rear panel of the Base Station, the Base Station should be away

from any metal obstructions, walls, and electronic equipments that can create radio interference. It is highly
recommended to place the antenna as high as possible in the center of the coverage and away from
obstructions. The antenna extension cable enables an antenna to be mounted away from the Base Station to
extend coverage.

Step 2: Plug the DC cable from the enclosed wall-adapter power supply into the 12VDC POWER connector (#9) on the rear of the

Base Station. Plug the large female connector at the end of the AC power cord into the power supply. Plug the other end of

BP250 BELT PACK SETUP AND PAIRING UP

When you operate each Belt Pack for the first time with the Base Station, you must pair up the Belt Pack with a Base Station. This
pairing process allows a Base Station and a Belt Pack to recognize each other. The Base Station will identify all Belt Packs that
paired up before and will recognize the difference between the Belt Packs. If a Belt Pack is added or replaced later, the new one is
necessarily to be paired up with the Base Station. If the previous Belt Pack will not be in use, turn off the Belt Pack or do the paring
process again with a different label.

A maximum of 32 Belt Packs can be paired up with each Base Station in the normal mode. If you need to pair up more than 32 Belt
Packs with the Base Station, additional 96 Belt Packs can be paired and those additional Belt Packs can be used in shared mode.
Belt Packs with which have been paired up in the shared mode operate in the „Push-to-Talk‟ mode and are allocated to
Communication Group “3” automatically. Base Station monitors the status for 32 Belt Packs in the normal mode and does not
monitor for additional 96 Belt Packs in shared mode.

NOTE: BP250 can also be paired up with the Base Station, MS150 and can connect with either Base Station that is lastly paired up.

BELT PACK SETUP

Before pairing up the Belt Pack with the Base Station, set up all Belt Packs as following steps:

Slide the cover down to open the battery cover (#10), and put a fully charged rechargeable battery pack (BAT50) or battery sled
with two fresh AA 1.5V alkaline batteries. Make sure the position of polarity (+, -) is correct. Close the battery cover.

RBS25 REMOTE BASE STATION SETUP

A Remote Base Station (RBS) can be connected to the Base Station through LAN, composing customized and continuous
coverage, and enabling automatic roaming between coverage zones. The Remote Base Station supports the communication with
Belt Packs in remote area from the Base Station. Standard CAT-5 cable is used to connect the Remote Base Station either directly
to the LAN port on the rear panel of the Base Station or via the Network Switch. Remote Base Station can be powered by a local
electricity or network switching device which has the Power-over-Ethernet (POE) function. Remote Base Station shares up to nine
(9) full duplex audio paths with the Base Station within the coverage area. Due to network traffic delay, audio breakups might occur
in communications between Belt Packs in the Remote Base Station, or in communications with Belt Packs which are paired up with
the Base Station. In that case, it is recommended to compose the network exclusively.

Figure 3-27. Connections example

Figure 3-26. RBS menu

34

NOTE: Not using dedicated network between the Base Station and the Remote Base Station, there would be delays due
to network traffic. When there are audio breakups due to the delays, it is highly recommended to compose a dedicated

network. „Dedicated Network‟ means LAN is used only by the Base Station and Remote Base Station without any other

devices connected.

STATUS LIGHTS ON THE FRONT PANEL OF THE REMOTE BASE STATION

RF ALERT light

When there are audio breakups seriously for each received frames, RF ALERT light will go on.

BS LINK light

When the Remote Base Station is connected to the Base Station, BS LINK light will go on.

BS ACTIVE light

When the Remote Base Station exchanges data with the Base Station, BS ACTIVE light will be flashing.

Step 4: Perform the coverage test

After installing the Remote Base Station initially, you can test the coverage areas to find optimal locations of the Remote

Base Stations.

TESTING COVERAGE AREAS

Checking Received Signal Strength Indication Level

Once the Base Station and Remote Base Station are properly connected and the pairing is done, turn on the Belt Pack
power and check the coverage area while walking around the Base Station or Remote Base Station. While talking and
moving around, check audio breakups and Received Signal Strength Indication („RSSI‟)(„A’) level on the Belt Pack‟s
NORMAL menu, as shown in Figure 3-28:

If RSSI Graphic bar is less than one and audio breakups start, that is the limit of coverage zone.

Mapping coverage zones

Draw a map of the coverage zone for the antenna of the Base Station and Remote Base Station as shown in Figure 3­29: While repeating this process, see if the Base Station and Remote Base Station cover the area enough.

Relocation of the Base Station and Remote Base Station

In a certain environment, audio breakups could occur even though high signal strength is observed.
There might be two reasons as followings:

 A Belt Pack is within 6.5 feet (2 meter) from the antenna that of the Base Station or the Remote Base Station.
 RF signals reflection could occur in an environment where there are a number of reflective surfaces, such as

metal obstructions, walls or other large structures and electronic equipments that can create radio interference.
You can relocate the Base Station or Remote Base Station antenna to avoid reflective surface. It is highly
recommended to relocate the antenna as high as possible in the center of the coverage and away from obstructions.
The antenna extension cable allows an antenna to be mounted away from the Remote Base Station for improved
antenna coverage.

Testing antenna Handoff

After testing the coverage zones of the antennas that of the Base Station and Remote Base Station, you should
continue to test handoff between the coverage zones. When your Belt Pack is out of coverage while walking through
coverage zones, the Belt Pack searches to find another antenna of the Base Station or Remote Base Station and
automatically roam to the antenna with the stronger signals. When the automatic roaming is performed smooth while
walking through Zone A and Zone B, the distance between the antenna locations of the Base Station and Remote
Base Station maybe ideal. In order to check the Belt Pack is connected to which of the Base Station or Remote Base

Stations, look at Belt Pack‟s NORMAL menu, („B’), as shown in Figure 3-28: If the Belt Pack is connected to the Base
Station, “BS” will appear. If a Belt Pack is connected to the Remote Base Station, “R1” will appear. You can also check
the status on the Base Station‟s MONITOR menu, as shown in Figure 3-30: The MONITOR menu shows each Belt

Pack is connected to which of the Remote Base Station or the Base Stations.

When the overlapping area is wide between coverage zones or depending on the site environments, automatic
roaming may not executed though the signal strength became weak and audio breakups occur. In that case, the Belt
Pack needs to be totally out of coverage first for an automatic roaming. Otherwise, the user can manually execute the
hand-off by double click the power(PWR) button of the front panel of the Belt Pack or, by quickly pressing group(GRP)
button while pressing the power(PWR) button and release both buttons. Expect a beep sound upon the new link to a
Base Station or Remote Base Station.

NOTE: When manually roaming, do not press PWR button longer than 2 second otherwise, the Belt Pack will be turned
off. In case of manual roaming, depending on the site environment and condition of installation, the Belt Pack could be
out of coverage with a voice message from headset with the red LED blinking and then roamed to the other coverage
zone with the green LED on.

SECTION 5: FAQS AND TROUBLESHOOTING

BASE STATION

Limited RF coverage

 Ensure that the antennas are properly connected and tightened on the Base Station.
 Confirm the antennas are positioned vertically and be folded completely as 90 degree.
 Check around the Base Station‟s line-of-sight and ensure that there are no physical obstructions around. While attaching

the antennas directly to the rear panel of the Base Station, the Base Station should be away from any metal obstructions,
walls, and electronic equipments that can create radio interference. If possible, the antenna should be located as high as
possible and away from obstructions and select location to the center of the coverage. The antenna extension cable
enables an antenna to be mounted away from the Base Station to improve antenna coverage.

TALK light on the Base Station does not come on

 Make sure that the power cords are properly plugged to the Base Station and standard wall outlet.
 Confirm that the POWER switch on the rear panel of the Base Station is turned on.
