This document describes the physical installation and basic configuration of the
Location Sensor product. The site design is detailed in the D0406 Location Sensor
Placement Guide.
2 PRODUCT DESCRIPTION AND FEATURES
The Location Sensor receives the signals transmitted by the WhereTags, which are
attached to the tracked assets. The decoded tag information is time stamped and
routed to a PC for additional processing. The locate algorithm running on the PC
calculates the tag position based on the time stamps of multiple Location Sensors,
and reports that position to the database where it is displayed by Resource
Manager.
There are two separate Location Sensor models:
• LOS-4100 (802.3 Wired Ethernet)
• LAP-4200 (with 802.11b Wireless LAN Access Point, also known as a
Locating Access Point)
The difference between the two models is that the LAP-4200 contains an Access
Point, while the LOS-4100 does not. These units are identical in appearance; the
only way to distinguish them is by the model number on the housing. Note that
both units have a wired Ethernet port; the LAP-4200 has a can function as either a
client bridge or an access point.
Both units also include a low power transmitter which is used to distribute
configuration data, and timing signals to other Location Sensor units. This
transmitter has the same transmitter characteristics as a tag.
Features include:
• Outdoor weatherproof housing
• Wireless data transport capability
• Wireless Timing capability
There are three separate antenna options for the Location Sensor. In addition,
there is an optional high gain Wireless LAN Access Point directional antenna for
installati ons in which the standard antennas do not proved the range required to
communicate with the base access point. The available antennas are listed in
section 4 below.
Antenna: MCX (female)
DC Power: 2.5 ID/ 5.5 OD mm (female)
Opt. Access Point Antenna: RP-TNC (male)
Ethernet RJ45 (female)
Timing RJH (4 wire telephone handset, female)
4 PARTS AND TOOLS
The parts and tools indicated below are required to complete the installation of the
Location Sensor. Ordering information is supplied where applicable.
• Hyperterminal (or any terminal emulation software) via serial port
For the LAP-4200, both the Location Sensor and the embedded Access Point must
be independently configured. That is, both units must have their IP addresses
correctly specified. The communication connection can be switched between the
Location Sensor and the Access Point by typing ctrl-w.
5.1 Location Sensor Configuration
Location Sensors communicate over an Ethernet interface using TCP/IP. Each
Location sensor must be configured with a unique IP address. The IP address of
each LS must be recoded and entered into the WhereNet site file, which contains
the configuration information for each LS, including its location.
Each Location Sensor is shipped with a label set containing one label (Figure 9)
with the bar coded MAC address of the Location Sensor (and of the Access Point
if so equipped) and three labels with the last six characters of the Location
Sensor’s MAC address in large type. Ensure that the label is correct by matching
the MAC address(es) on the loose label set with the MAC address(es) listed on the
back of the Location Sensor. Place the loose bar code label in the site design
document where indicated, and place one or more of the large type, six character
labels on the exterior of the Location Sensor in positions that are visible after
installation.

Like other network equipment, the Location Sensor IP address(es) must be set to a
predetermined address. While there is no restriction to the IP address, it must
match the address in the Site file for that particular Location Sensor. The IP
address(es) can be static assigned, or dynamically assigned via DHCP. If assigned
though DHCP, the DHCP server must contain the MAC address and
corresponding IP address for each of the Location Sensors (and Access Points).
The Outdoor Omni antenna must be mounted to the Location Sensor housing; the
Indoor Office Omni antenna and the Flat Panel Directional antennas are mounted
separately to the appropriate wall or ceiling. Follow the specific instructions
included with the antennas.
The left and right antenna must be correctly oriented per the site design.

8 MOUNTING OVERVIEW
The site design specifies the location of the Location Sensor(s) to provide
optimum system performance. It is critical that the Location Sensor is mounted in
a position which provides good RF visibility to the tracked assets. Thus the
Location Sensor must be mounted exactly in the position specified in the site
design document.
Failure to mount the Location Sensor in the exact position specified in the site
design will result in erroneous or non-locates of the tracked assets.
The Location Sensor can be mounted to a wall using the integral keyhole mounting
slots. An attachment hole is also provided to accept a 3/8 in (10 mm) threaded
rod. A pole mount hardware kit is available separately.
8.1 Wall Mount
The Location Sensor may be mounted directly against a non-metallic wall using
the standard AK-210 All Weather Omni-directional antennas. For a metallic wall,
Location Sensor must be mounted 12 inches (305 mm) away from the wall for the
antennas to operate properly. Alternately, the AK-120 Flat Panel antennas may
utilized as they may be mounted directly to a metallic wall.
The Location Sensor can be mounted to a wall using the four key hole mounting
slots per the following instructions:
• Determine the preferred screw/ anchor type (not supplied) for the particular
wall material. The Location Sensor requires a #6 or 3.5 mm mounting
screw.
• Mark and drill holes in the wall to match the keyholes on the Location
Sensor (Figure 10).
• Mount the Location Sensor and securely tighten the screws.
If the Location Sensor is in a position in which it could be ripped off the wall
by industrial equipment, it should be secured to the building infrastructure
with a safety cable through the 3/8 inch (10 mm) hole in the housing.
The Location Sensor can be hung via a 3/8 inch (10 mm) threaded rod per the
following instructions. The required supports, threaded rod, nuts, etc., are not
included.
• Cut the threaded rod to the desired length and install it directly above the
desired Location Sensor position.
• Thread one nut up 2 inches (50 mm) from the bottom of the threaded rod.
• Place the Location Sensor onto the threaded rod and install the second nut.
• Tighten the upper nut down on top of the Location Sensor housing.
8.3 Pole Mount
The required pole mount kit, catalog number RM-410-00, must be ordered
separately. The Location Sensor can be mounted to a pole per the following
instructions:
Figure 11 below shows the connections which must be made to the Location
Sensor in normal operation. The connector types and recommended cable types
are detailed in section 4 above.

9.1 Power
The customer must provide 120 Vac power to the specified Location Sensor
position. The Location Sensor utilizes an external power supply to convert 120
Vac to the required +18 to 36 Vdc. The recommended power supply has a 6 foot
(2 m) AC cable and a 6 foot (2 m) dc cable. The electrician should verify that the
AC power is available within 3 feet (1 m) of the position of the Location Sensor.
This allows a 9 foot (3 m) “service loop” margin if the Location Sensor position
must be readjusted after the AC power is installed.
For outdoor installations the power supply must be installed within a suitable
waterproof housing. Follow local and national building codes.

9.2 Timing
______________
For most indoor and some outdoor applications the Location Sensor requires at
least one timing cable to be connected to other nearby Location Sensor units. The
site design document will specify which Location Sensors will be connected
together. Each of the three timing ports on the Location Sensor is an identical bidirectional link. The cable and connector types are specified in section 4 above.
For a reliable system operation, the jacket of the timing cable must be
securely crimped inside the RJH connector. Standard eight conductor cat 5
cable is too large for crimping in the 4 wire connector; the recommended 4
wire cable must be utilized to ensure a proper crimp.
The following rules must be applied when connecting timing cables between the
Location Sensors:
• Do not connect the timing cable from one Location Sensor back to the
same Location Sensor.
• Do not connect two timing cables between the same two Location Sensors.
• The maximum timing cable length is 1000 feet (310 m).
Install the Location Sensor timing cables from one unit to the next, as specified in
the site design document, using the specified 2 pair Cat 3 cable and RJH
______________
(telephone handset) connectors.
Incorrect routing of the timing cables between the Location Sensors may
result in decreased location accuracy.
9.3 Ethernet
The Location Sensor utilizes standard 10/100 802.3 Ethernet connectivity via cat 5
cables. The Location Sensor must be wired to a nearby hub, which is in turn
connected to the network containing the database cpu. The maximum Ethernet
cable run is 328 feet (100 m). If additional distance is required, hubs, repeaters,
and fiber (with 10baseT converters) can be used to extend the distance. Refer to
IEEE guidelines for Ethernet cabling.
Do not exceed the maximum Ethernet cabling length of 328 ft (100 m).
9.4 Access Point Antenna Cabling (Optional)
In many installations, the Access Point antenna must have omni directional RF
coverage to support communication from nearby 802.11 wireless terminals. Thus,
in the standard configuration the Access Point shares the same antennas as the
Location Sensor.
However, in some installations the distance between the Location Sensor and the
receiving Access Point is beyond the maximum **TBD** range supported by the
omni directional antennas. In that case the optional high gain antenna must be
utilized to permit the embedded Access Point to communicate with the receiving
Access Point. The high gain Access Point antenna will increase the
communication range to approximately 2000 feet (620 m) (US Only), at a bit rate
of 1 MB/s, when used in conjunction with a receiving omni directional antenna.
The range in Europe will be less due to regulatory output power restrictions.
The installation of each Location Sensor must be verified by the Account Manager
to ensure that it was correctly installed at the location specified in the Site Design
document. The Account Manager should also record the MAC and IP addresses of
each Location Sensor. After verifying these items the Account Manager should
initial and date the table at the end of this section.
q Location Sensor mounted within +/-1 foot (0.3 m) of position specified in
Site Design document. After measuring the installed position,
documenting it on the following form, and comparing it to the position
specified in the Site Design document, the Account Manager should place

10.2 Location Sensor Operational Verification
Prior to optimizing locate performance, the operation of the Location Sensor must
be verified. The checklist below specifies the verification of the configuration and
basic operation.
q Confirm that the site LS channel assignment is correct by running “display
locate” from the LP Manager tool with a tag placed directly under each LS.
Verify that the nearest LS, as indicated by a “0” in the display locate
report, is that LS nearest the tag.
q Verify that detects are received on the channel by using either LP Manager
Detect History, or WT LPHealth APC detects when a tag is placed at a
distance from each LA equivalent to the maximum required range from
that LA. Typical tag to LA range is 1000 ft (305 m) (Unobstructed/
outdoor), 350 ft (107 m) Minimally Obstructed (indoor office/ light
commercial), 250 feet (76 m) Significantly Obstructed (heavy industrial).
