TSL 2128L bluetooth® RAIN RFID UHF reader with high gain linear antenna and ePop-Loq

Overview of the TSL 2128L

The TSL 2128L bluetooth UHF RFID RAIN reader is one of the most powerful handheld RFID readers developed by Technology Solutions UK Ltd (TSL) – a global leader in radio frequency identification technology.

Equipped with a high-gain linear antenna, the TSL 2128L delivers outstanding long-range performance of up to 15 meters (49 feet) – the farthest read range in TSL’s entire handheld RFID lineup.

This makes it the ideal choice for operations requiring simultaneous tag reading, long-range scanning, and high precision, such as warehouse management, supply chain tracking, asset management, and garment logistics.

Rugged, durable, and ergonomic design

The TSL 2128L is designed for comfortable handheld use, featuring an ergonomic pistol grip that allows operators to work efficiently during long shifts.

Its rugged housing is built from impact-resistant materials, ensuring durability in harsh industrial or outdoor environments.

TSL’s patented ePop-Loq® technology provides a secure mechanical and data connection between the reader and a mobile device (such as a smartphone or PDA), while automatically detaching safely if dropped — protecting both devices from damage.

Additionally, the TSL 2128L supports simultaneous charging of both the reader and connected mobile device via a dedicated docking station, optimizing workflow efficiency and convenience.

Exceptional read performance with a high-gain linear antenna

The standout feature of the TSL 2128L is its high-gain linear polarized antenna.

Unlike circularly polarized antennas, which split RF power between two polarization directions, a linear antenna concentrates all radio frequency energy into a single direction — enabling dramatically extended read ranges, up to 15 meters (49 feet).

The antenna’s design is optimized for consistent scanning performance both in front of and to the sides, making it ideal for environments with dense tag populations or applications requiring long-range, directional reading.

Key advantages:

• Longest read range in TSL’s handheld series – up to 15m (49ft)

• Superior tag sensitivity with minimal signal interference

• Consistent scanning performance across multiple angles

• Ideal for applications requiring directional and focused tag reading

Note: Linear antennas depend on tag orientation. Therefore, the 2128L performs best in environments where tag alignment can be controlled, such as garment tracking, conveyor systems, or items with fixed label placement.

Flexible Bluetooth® connectivity – multi-platform compatibility

The TSL 2128L supports both bluetooth classic and bluetooth low energy (BLE), allowing seamless connectivity with major operating systems:

• Android

• iOS (Apple)

• Windows

• macOS

It can operate in multiple modes:

• SPP (Serial port profile): for high-speed data transfer

• HID (Human interface device): acts as a keyboard input

• iApp2 (Apple): optimized for iPhone and iPad integration

The auto-reconnect feature maintains stable communication, ensuring uninterrupted scanning even when the connection is temporarily lost during movement or range shifts.

Massive data storage – up to 250 Million tags

With an integrated 16GB MicroSD card, the TSL 2128L can store up to 250 million EPC tag records, each with precise timestamp information.

Its Batch Mode enables offline data collection – perfect for situations without Bluetooth or Wi-Fi connectivity. Data can later be synchronized easily with a PC or management system via Dock or USB cable.

Storage capabilities:

• Over 1 million tag reads handled efficiently

• Up to 50,000 unique tags processed directly within the reader

• 250 million tags storable on the extended memory card

• Real-time clock for accurate timestamp recording

Advanced tag search and smart user feedback

The TSL 2128L is not only powerful but also intelligent.

It features LED indicators, audio beeps, and vibration feedback, providing clear, real-time signals during scanning. These cues help users quickly confirm successful reads and locate specific tags with ease.

The Search & find mode allows precise identification of individual tags among thousands, making it perfect for asset tracking, warehouse auditing, and locating misplaced items.

Enhanced data security – wired communication option

Thanks to ePop-Loq® technology, the TSL 2128L can establish a direct wired connection with the host device, ensuring maximum data security without relying on wireless transmission.

This feature is especially valuable in sensitive or high-security environments, such as banking, healthcare, or defense, where wireless data transfer may pose risks.

In addition, the 2128L supports batch data collection, allowing information to be securely stored and later synchronized even when wireless networks are unavailable.

Smart charging and synchronization solution

TSL provides a dedicated docking station for the 2128L, allowing both the reader and an attached smartphone to charge simultaneously via the ePop-Loq® mount.

Each docking station Kit includes:

• Docking station

• Power supply unit

• USB data cable

The flexible design is compatible with a wide range of smartphones and handheld devices, allowing easy integration into existing workflows without infrastructure changes.

Powerful software development tools – ASCII 2 protocol

A major advantage of the TSL 2128L is its flexible software integration.

The reader uses TSL’s proprietary ASCII 2 protocol, enabling developers to send complex RFID commands through simple text-based instructions.

This approach simplifies software development, shortens integration time, and ensures full compatibility with other TSL models, such as 1128, 2128P, 1153, 1166, and 2166.

Benefits of ASCII 2 protocol:

• Faster software development and deployment

• Simplified command structure using ASCII strings

• Seamless integration with existing RFID applications

• Easy scalability for future upgrades

Key applications of the TSL 2128L

With its long read range, high accuracy, and massive storage capacity, the TSL 2128L is perfectly suited for multiple industries and use cases:
