  • Field Service

  • Manufacturing

Unitech’s RM300 series is a high-performance UHF RFID reader module based on Impinj R2000 chip and compliant with EPC C1 Gen2 / ISO 18000-6C and FCC modular approval requirements.  System Integrators, RFID device makers could use RM300 to develop their own products with the benefits of cost-efficiency and high-performance.

 

Features

• Support for EPC C1 Gen2 / ISO 18000-6C tag protocol with anti-collision, DRM and Listen-Before-Talk features
• International operation with global frequency coverage over 860-960 MHz band
• Offer two kinds of models with two or four (MMCX) antenna connectors for choice
• Adjustable transmit output level control from 5 dBm to 30 dBm in 1 dB step
• Maximum tag read rate of over 900 tags per second

• Maximum tag read distance of over 27 feet (9 m) with 6 dBi antenna
• Easy to use Starter Kit to shorten product development time

Unitech’s RM300 series is a high-performance UHF RFID reader module based on Impinj R2000 chip and compliant with EPC C1 Gen2 / ISO 18000-6C and FCC modular approval requirements.  System Integrators, RFID device makers could use RM300 to develop their own products with the benefits of cost-efficiency and high-performance.

RM300 series has two models, one is named RM300-2port with two (MMCX) antenna connectors and the other one is RM300-4port with four (MMCX) antenna connectors. The antenna connectors of  RM300-2port that can be configured as one bi-static antenna or two mono-static antennas.  It also supports dense reader mode (DRM), anti-collision, and Listen-Before-Talk (LBT) features. RM300 has an operating distance up to 9 meters when its adjustable TX power is set to 30 dBm with a 6 dBi antenna. In addition, RM300 is small and ideal for adding UHF RFID read/write capabilities to a wide range of products and solutions such as handheld PDA, label printers, stationary readers, or any other device for UHF RFID applications. RM300 uses Serial and USB interfaces to connect to an external processor board or PC host.

Unitech offers a starter kit to enable you to design RM300 into your products quickly and easily. This kit includes SDK, demo code, driver, and documentation. With its tiny size, excellent operating range, and high quality UHF RFID technology, RM300 is the perfect solution for embedded RFID applications.
