The Sargas 4-Port is a networked tracking device operating on UHF/RAIN. Priced over $1500, compare its legacy middleware requirements to Nextwaves.
Technical verdict
Do not evaluate Sargas (4-Port) by list price alone. Its strongest fit is a project that already uses Ethernet, USB, Micro SD, 8 GPIO, has time for RF tuning, and accepts extra middleware work. If the engineering team needs open APIs, realtime data, and faster edge-to-cloud deployment, Nextwaves NR155 is the stronger replacement path to evaluate.

Deployment review
Fixed UHF RFID projects that already use Ethernet, USB, Micro SD, 8 GPIO and have time for RF tuning.
Do not compare device price only; total cost depends on accessories, software, and integration.
IP52, PoE or 5V DC, 87 x 80 x 23 mm, and 0.3 kg must match the site layout.
Plan for middleware, SDK work, duplicate filtering, and business-event mapping.
Alternative architecture
The ThingMagic (JADAK) Sargas (4-Port) is an industrial-grade RFID device. It operates within the UHF/RAIN (global) range and supports the EPC Gen2V2, ISO 18000-63, Gen2X standard, making it widely deployed across enterprise logistics applications.
With an IP rating of IP52, it offers protection against specific environmental conditions typical in warehouses or retail backrooms. The reader utilizes PoE or 5V DC for continuous performance, while its stated maximum read rate peaks at 750.
In modern deployments, network integration is the most significant hurdle. This model offers Ethernet, USB, Micro SD, 8 GPIO options for transferring data back to central systems.
However, a major bottleneck with legacy ThingMagic (JADAK) hardware is the heavy reliance on proprietary SDKs (like LLRP) or expensive third-party IoT middleware to process raw tag data into meaningful business intelligence.
If your engineering team is evaluating the ThingMagic (JADAK) Sargas (4-Port), the Nextwaves NR155 presents a vastly superior cloud-native architecture. Legacy systems inherently drive high capital expenditure through vendor lock-in and proprietary software ecosystems.
Nextwaves completely eliminates this barrier by providing a standard MQTT REST API directly on the device. Your software developers can integrate tag reading directly into your custom ERP or WMS backend in days instead of months, completely bypassing recurring middleware licensing fees.

The ThingMagic (JADAK) Sargas 4-Port is a high-performance, networked RFID reader. Designed around the ThingMagic M6e Micro module, it supports EPC Gen2V2, ISO 18000-63, Gen2X over UHF/RAIN (global) frequencies for edge computing deployments.
The base unit is commonly priced around $1500. A comprehensive bill of materials also requires budgeting for 4 external antennas, RF cabling, and establishing a stable PoE or 5V DC power environment.
Nextwaves provides embedded REST API and MQTT endpoints directly in the hardware stack. Consequently, software engineering teams can bypass expensive custom IoT middleware and integrate RFID events directly to internal webhooks.
The compact aluminum housing weighs approximately 0.3 kg and measures 87 x 80 x 23 mm. It features an IP52 rating, making it robust against dust and light drip exposure, but unsuitable for direct outdoor weathering.
Corporate network integration routes through its Ethernet, USB, Micro SD, 8 GPIO interfaces. The extensive 8-pin GPIO allows direct logic interactions with stack lights, programmable logic controllers, and motion sensors.
Physical cabinet mounting uses the integrated flange holes. Optimizing RF performance often requires utilizing the Mercury API to properly configure read/write parameters for the specific Gen2X subset tags in your facility.
Under laboratory test conditions, the reader is capable of processing up to 750 tags per second. Extensive device configuration utilizes the proprietary JADAK Universal Reader Assistant (URA) utility.
Most enterprise deployments require custom C# or Java applications utilizing the Mercury API to interface effectively with the Ethernet, USB, Micro SD, 8 GPIO ports, adding significant software lifecycle maintenance.
The manufacturer typically provides a standard one-year hardware warranty. Complex factory deployments usually benefit from purchasing extended support SLAs and integration consultancy.
External RP-SMA connected antennas are strictly required. Careful calibration of these RF ports across the UHF/RAIN (global) frequency bands ensures maximum range without violating local ETSI/FCC regulations.
