IH21
Bluetooth® UHF RFID Reader
Quick Start Guide
IH21-EN-QS REV A
08/18

Introduction
The IH21 Bluetooth® UHF RFID Reader provides Ultra High Fre-
quency (UHF) Radio Frequency Identification (RFID), with
optional barcode scanning functionality. The unit can be used in
batch mode using an optional Micro SD card, or can be con-
nected via USB through the ePop-Loq® socket, or connected to a
host device via Bluetooth. The IH21 can read and write to EPC
Global Class 1 Gen 2 UHF RFID transponders.

Battery Installation
The battery is charged using a docking station and is therefore
unlikely to need to be changed once installed. To access the bat-
tery compartment the grip handle must first be removed.
Step 1. Push the handle release latch upwards and slide the
trigger handle off the main body.
Step 2. Remove the battery cover.

Step 3. Insert the battery, ensuring contacts align with the
contacts on the Main Body.
Step 4. Re-attach the battery cover and trigger handle.

Charging
To comply with international shipping regulations, batteries
included with the product are discharged to less than 30% of
their maximum capacity when shipped. It is therefore important
that the unit is fully charged before using the IH21 UHF Reader
for the first time.
The IH21 UHF Reader can be charged using the dedicated IH21
Docking Station. The Docking Station has an input for power
and mini USB connector for data communications.
Button Operation
The IH21 UHF Reader has a Primary button action, which can be
initiated by single click of the Trigger Button. The Single click
button options are also programmable for custom applications.

Reading Transponders
The IH21 UHF Reader can read and write to UHF RFID tran-
sponders when they are in range of the antenna. The antenna is
located on the front of the IH21 UHF Reader and the read zone
is in front of the antenna.
The range at which a transponder can be read depends on the
transponder type and size, and the number of transponders in
the field.

Attaching Devices
The IH21 UHF RFID Reader has an ePop-Loq mount which
allows mobile terminals to be physically attached to the IH21
UHF Reader. Custom ePop-Loq cases allow compatible devices
with custom applications to communicate with the reader via
USB instead of Bluetooth.

Fitting an ePop-Loq case
Step 1. Ensure the mobile terminal is fitted into its ePop-Loq
case before attaching the case to the IH21 UHF RFID
Reader.This prevents over-flexing of the case.
Step 2. Make sure all of the contacts - on both the ePop- Loq
socket and stud - are clean and free from dirt or debris.
Step 3. Align the ePop-Loq stud with the ePop-Loq socket -
ensuring that the front of the host device is pointing
towards the antenna - and press thetwo parts together
until they click into place.
Step 4. Toremove the ePop-Loq case, pull in the opposite
direction. Do not twist the devices whenseparating.

USB Connection
The ePop-Loq USB connection on the IH21 can be configured in
one of two modes – Charge-Only or Charge-and-Data. Please
ensure the mode required is correctly configured.
• Charge-Only mode: Both the IH21 UHF Reader and the
mounted device will be charged when docked in the charging
cradle, but will never use the USB data connection.
• Charge-and-Data mode:Compatible devices will use the USB
data connection when not in the charging cradle. Note that
USB data connection to the IH21 requires a custom
application that supports the TSL
® ASCII protocol over USB.
Bluetooth Connection
The IH21 Bluetooth Handheld UHF RFID Reader is compatible
with many Bluetooth wireless technology enabled host devices
including Android and Xamarin.
The Bluetooth version is BT4.2 and supports both Bluetooth Low
Energy and Bluetooth Classic.
To pair with a Bluetooth host device
Squeeze the Trigger Button to wake up the IH21 UHF Reader
and wait for the blue LED to start flashing (if it does not flash,
please check the battery is charged and properly installed).
In your host device’s ‘Bluetooth® Settings’ page, search for and
pair with the IH21 UHF Reader. In the list of Bluetooth® devices,
the IH21 UHF Reader will be identified by its serial number
(xxxxxx-IH21). (Make sure the Reader has not ‘timed-out’ and
gone to sleep, as it will not be discoverable).

Once a Bluetooth® connection has been successfully established,
the blue LED will stop flashing and stay on continuously.
Install a compatible application (such as TSL®’s RFID Explorer
App) on your mobile terminal. RFID Explorer can be downloaded
from the App Store or Google Play.
Open your compatible application and select the IH21 UHF
Reader
from the list of available devices. The IH21 UHF Reader should
now be ready to use!
Bluetooth Operating Mode
Note: The UHF RFID Bluetooth Readers support two different
modes of operation over Bluetooth.
Bluetooth SPPMode
By default, the IH21 UHF Reader is set to SPP Mode. In this
mode, the IH21 UHF Reader will only work with Apps that have
been written with specific support for the IH21 UHF Reader. SPP
Mode allows access to the full range of features available on the
IH21 UHF Reader.
The IH21 UHF Reader must be set to SPP mode in order to work
with RFID Explorer or any of the other free TSL
® Apps
(www.tsl.com/apps).

Bluetooth HID Mode
In HID mode, the IH21 UHF Reader appears as a Bluetooth Key-
board, making it compatible with the majority of Apps or Web
Apps.Apps receive input as key strokes from the Reader. HID
mode is better suited to reading UHF tags one at a time.
Further Information
For a detailed comparison between Bluetooth HID and SPP
modes - and instructions on how to switch between these
modes - download the ‘Comparison of Bluetooth Modes for TSL
®
UHF Readers’ document from the IH21 Downloads Page
(www.tsl.com/IH21-downloads).
For information and examples on configuring HID mode, down-
load the ‘Bluetooth HID mode’ application note (www.tsl.com/
IH21-downloads).
