Unitech RM100 UHF RFID Reader Module
Introducing the RM100 UHF RFID Reader Module
Unitech’s RM100 is a high-performance UHF RFID reader module based on the Impinj R2000 chip. It is compliant with EPC C1 Gen2 / ISO 18000-6C. RM100 has one (Ipex) antenna connector. It also supports dense reader mode (DRM), anti- collision, and Listen-Before-Talk (LBT) features. RM100 has a long operating distance of up to 9 meters when its adjustable TX power is set to 33 dBm with a 4 dBi antenna. RM100 is small (55 mm 35 mm x 4.3 mm) and ideal for adding UHF RFID read/write capabilities to a wide range of products and solutions, such as RFID handheld PDAs, label printers, and stationary readers. RM100 uses Serial and USB interfaces to connect to an external processor board or PC host.

Tour of the RM100 UHF RFID Reader Module
This section describes the main components and features of the interface
board.
Installing the IndyTool
First of all, install the IndyTool before connecting the interface board to a PC. It is possible for multiple versions of IndyTool to co-exist on a single system, so long as a unique install path is used for each, such as the default installation directory.
Installation Procedure
- Double-click the IndyTool installer file, IndyTool v2.6.msi, to launch the installation wizard.
- When prompted, designate the desired installation directory. The default is: [Program Files]\IMPINJ\IndyTool v2.6
- Installation includes the C++ runtime libraries and adds a desktop shortcut to the IndyTool application.
- To Start the IndyTool application:
- Double-click the desktop shortcut, or
- Use the Start Menu. For example, if installed to the default directory:
- Click Start, select All Programs, IMPINJ, Impinj IndyTool v2.6, and click IndyTool.
- Open the IndyTool installation folder and double-click IndyTool.exe.
Connecting the RM100 to a PC
Before operating the Indy tool software for the development of the RFID
device, follow the steps made below to connect the RM100 to a PC.
- Install the Indy tool on your PC.
- Mount the UHF RFID Module onto the interface board.
- Connect the interface board to a PC by using a micro USB cable.
- Insert the power connector into the power inlet on the interface board, and then plug the power adapter into an electrical socket.
- Insert the connector of the antenna into the antenna port of the RM100 UHF RFID Reader Module.
- Open the IndyTool. Click Start to scan RFID tags by using the RM100 UHF RFID Reader module.
FCC
Federal Communication Commission Interference Statement
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. However,
there is no guarantee that interference will not occur in a particular
installation. 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 of the
following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and the receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: To assure continued compliance, any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. (Example – use only shielded interface cables when connecting to computer or peripheral devices).
End Product Labeling
This transmitter module is authorized only for use in devices where the
antenna may be installed such that 20 cm may be maintained between the antenna
and users. The final end product must be labeled in a visible area with the
following: “Contains FCC ID: HLERM100U”
End Product Manual Information
The user manual for end users must include the following information in a
prominent location “IMPORTANT NOTE: To comply with FCC RF exposure compliance
requirements, the antenna used for this transmitter must be installed to
provide a separation distance of at least 20cm from all persons and must not
be co-located or operating in conjunction with any other antenna or
transmitter.” This device complies with part 15 of the FCC rules. Operation is
subject to the following two conditions (1) This device may not cause harmful
interference and (2) This device must accept any interference received,
including interference that may cause undesired operation.
IMPORTANT NOTE
In the event that these conditions can not be met (for example certain laptop
configurations or colocation with another transmitter), then the FCC
authorization is no longer considered valid and the FCC ID can not be used on
the final product. In these circumstances, the OEM integrator will be
responsible for re-evaluating the end product (including the transmitter) and
obtaining a separate FCC authorization. This device is intended only for OEM
integrators under the following conditions: The antenna must be installed such
that 20 cm is maintained between the antenna and users. As long as the
condition above is met, further transmitter test will not be required.
However, the OEM integrator is still responsible for testing their end product
for any additional compliance requirements required with this module installed
(for example, digital device emissions, PC peripheral requirements, etc.).
