PRM240-R2

Overview
Ezurio’s PRM240-R2 is a
hardware-compatible replacement for our LT1110 and PRM240 proprietary 915 MHz
FHSS module. It carries a new set of certifications and provides a continued
availability for those already designed in with our previous 915 MHz modules.
Based on proprietary FlexRF™ technology, this globally accepted module will
exceed most OEM application and performance requirements.
Embedded with Ezurio’s robust
server-client protocol, the PRM240-R2 permits an unlimited number of clients to
synchronize to a single server for low latency communications. The server and
all clients in a network can communicate with any radio in range via either
addressed or broadcast packets. The configuration and test software allow OEMs
to design and test networks to suit their applications.
The enhanced API commands provide packet routing control and network intelligence. With its field proven proprietary FHSS RF protocol and increased penetration at 915 MHz, the PRM240-R2 rejects RF noise, excels in multipath scenarios, allows for co-located systems, and provides an extremely reliable communication link.

Can the PRM240-R2 communicate over the air with existing AC4490 or AC4790 modules?
No. The PRM240-R2 operates on our Server-Client FlexRF™ FHSS protocol (up to 230 kbps) rather than the legacy AC4x90 protocol. Legacy networks cannot communicate directly over-the-air with PRM nodes, and host software/framing must be updated to match the PRM protocol. The Peer-to-Peer protocol supported on the AC4790 is not supported.
For additional information please reference the User Guide - PRM240-R2.
Is the PRM240-R2 a direct pin-for-pin drop-in replacement for AC4490 modules?
No. The PRM240-R2 uses a different physical footprint and interface pinout than the AC4490 series. While it is a direct drop-in replacement for legacy LT1110/PRM240 pluggable U.FL designs, AC4490 customer layouts will require board-level hardware redesign or interface adaptation. Please reference the PRM240-R2 Datasheet for additional information.
With the end-of-life (EOL) of the AC4x90 series, what 900 MHz alternative does Ezurio offer?
Ezurio has released the PRM240-R2 proprietary 900 MHz FHSS module publicly to provide an available 900 MHz option for customers affected by the AC4x90 EOL who need to maintain supply for their applications.
What antenna options and modular certifications apply to the PRM240-R2?
The PRM240-R2 features an onboard U.FL connector for external antenna integration. Modular certifications cover a specific list of approved antennas. Using high-gain directional antennas (such as Yagi antennas) or custom antenna setups outside the approved list will require end-system regulatory testing. Certification documentation and antenna lists are available in section 8 of the PRM240-R2 Datasheet.
Are all antenna and form factor variants of the LT1110 / PRM240 supported by the PRM240-R2?
No. The PRM240-R2 is available exclusively as a pluggable module with an onboard U.FL connector (Part Number: 453-00418). While it is a direct drop-in replacement for pluggable U.FL LT1110/PRM240 designs, legacy variants with integrated chip/trace antennas or surface-mount (SMD) packaging are not directly replaced by this part number.
For a full list of antennas certified with the PRM240-R2 please reference section 8.2 of the PRM240-R2 Datasheet.
How do I obtain a Development Kit (DVK) or samples to evaluate the PRM240-R2?
To ensure seamless design support, Development Kits and sample hardware are allocated directly through our sales team. Please reach out to your Ezurio Sales Representative or submit a request through our Sales & Product Information Portal on the Contact Us page of our Website, to request a DVK and sample units for your qualification process.
Are there any protocol or host software changes required when dropping in a PRM240-R2 to replace an LT1110/PRM240 module?
No. The PRM240-R2 utilizes the same robust Server-Client FHSS wireless protocol (up to 230 kbps RF data rate). It supports the standard UART interface and configures seamlessly via Ezurio’s Configuration and Test Utility Software, as explained in the Configuration and Test Utility Software User Guide- RAMP Modules
Do I need to re-certify my end product when updating to the PRM240-R2?
The PRM240-R2 carries updated regulatory certifications, including FCC modular approval. Depending on your end-system integration, you may be able to leverage our modular grant filings to simplify your compliance updates. Complete certification details and test reports are available. Contact support@ezurio.com for details.
Is the PRM240-R2 a direct drop-in replacement for my current LT1110 / PRM240 layout?
Yes, for pluggable U.FL configurations. The PRM240-R2 (Part Number: 453-00418) features the exact same pluggable form factor (4 mm x 39 mm x 25 mm) and pinout as the legacy pluggable LT1110/PRM240 U.FL variants. If your design utilizes an surface-mount (SMD) or integrated trace/chip antenna variant, please contact our engineering team to review pinout and mechanical adaptation options for the pluggable U.FL unit.
What is the PRM240-R2, and how does it relate to the LT1110 / PRM240 series?
The PRM240-R2 is an updated, hardware-compatible redesign of our legacy LT1110 and PRM240 proprietary 915 MHz FHSS modules. It provides extended supply availability and updated regulatory certifications for customers with existing 915 MHz FlexRF™ designs.
