InTouch Care User Manual
Introduction
InTouch Care is an Active RFID tracking system. The system is comprised of four basic
elements:
1. TAGS – The TAGs are battery operated and are comprised of an RF Transceiver
and a few peripheral components. The TAGs are small devices with about 1” X
2” foot print. They are typically attached to assets or people that need to be
tracked.
2. Spiders – The Spiders are also battery operated and are equipped with similar to
the TAG RF transceiver and other peripheral components. Unlike TAGs, Spiders
are not mobile. They are typically attached to either ceilings or walls. Their
function is to improve the localization capability of the system.
3. STARs – The STARs are operated either using an external power supply or a
POE power supply within the device. STARs are also equipped with essentially
identical RF section to both the TAGs and the Spiders. The STARs are also
equipped with a LAN chip for communication with the server.
4. Server – The servers can be either local or can be connected directly to any
Internet server. The Servers are in direct communication with the STARs.

STAR Installation and Operation
Installation
Stars should be installed as high as possible. It is preferred to attach them to the ceiling
upside down such that the antennas point downward. The antennas should be positioned
at 90 degrees to each other and perpendicular to each other. Stars can be fed through one
of two methods:
1. Power Over Ethernet (POE) or
2. External 3.3 volts power supply.
The STAR must be connected to the LOCAL AREA Network (LAN) which must be
connected to InTouch Server.
Operation
The STAR communicates with all InTouch Components and is responsible to
communicate information it receives to and from InTouch server. InTouch network can
support up to 128 STARs
Maintenance
STAR malfunction is immediately sensed by the InTouch Server. The Network needs to
be tested for before it is determined that the SART fails. In case, a STAR malfunctions it
should be replaced with one in inventory.
FCC NOTICE:
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio
communications. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Consult the dealer or an experienced radio/TV technician for help.
• The carrier frequency is 904MHz – 926MHz.
• The RF output power (or field strength and measurement distance) is less than one
milliwatt.
TAG Operation
Installation
In order to initiate a TAG the user must install a battery in the TAG. The preferred
battery is CR 2335 that is enclosed in the TAG package. Other alternatives are CR2330
and CR2032. Both of the alternate batteries need a plastic shim that is included in the
package. There is no on/off button on the TAG and it will start operation as soon as the
