NEDAP UPASS TARGET: LONG-RANGE VEHICLE & DRIVER ACCESS SYSTEM

The Nedap uPass Target is a high-end, long-range UHF RFID Antenna specifically designed for automatic vehicle identification (AV), traffic flow monitoring, and access systems in demanding industrial environments.

Unlike standard proximity readers that require a card swipe from a few inches away, the uPass Target utilizes Ultra-High Frequency (UHF) technology to identify moving vehicles, rolling stock, and heavy equipment seamlessly from a distance.

BENEFITS & KEY ADVANTAGES

Long-Range Performance

Basically, it can automatically identify vehicles from a distance of up to 50 feet (15 meters), with select specialized tags (like the UHF Heavy Duty Tag) being read up to 60 feet (18 meters) away.

Cost-Efficient Passive Technology

Additionally, the reader operates using battery-free UHF tags (EPC Gen 2), meaning the tracking solution is highly cost-effective and the credentials require zero maintenance.

Tag Orientation Freedom

Also, it features and integrated circular polarized antenna, ensuring that credentials can be read at any angle as long as they are within the direct line of sight.

Versatile Tracking Capabilities

Beyond primary vehicle identifications, it is versatile enough to be used for tracking people or rolling stock.

Simplified Power Over Ethernet (PoE+)

The device can be powered directly through its TCP-IP interface using PoE+, which eliminates the need for installing separate power supply wiring.

Advanced OSDP Security

By supporting Open Supervised Protocol (OSDP v2), it establishes highly secure, advanced channel communication between the reader and the controller.

Flexible Systems Integration

It supports a wide array of industry-standard communication interfaces (RS485, RS422, Ethernet, and Wiegand) and protocols (such as Magstripe/Clock &Data), enabling seamless integration into new or pre-existing access system and parking infrastructure.

Heavy-Duty Industrial Design

Certainly, it features a durable, IP66-rated weather-proof enclosure that operates solidly under tough outdoor conditions and extreme temperatures ranging from -22°F to +150°F (-30°C to +66°C). It also utilizes high-quality, Industry-standard M12 connectors for stable terminal connections.

Extendable Coverage with an External Antenna

It includes a dedicated TNC antenna input to support an optional external uPass Target Antenna. This allows operators to easily extend the read range scope or monitor both vehicle entry and exit lanes using a single reader configuration.

Easy Installation & Calibration

A standard wall mounting set is included, making it simple to adjust the reader to the exact angle required for reliable reading. It also features an adjustable read range to fit specific site designs.

Clear User Feedback

Built-in high-intensity blue, green, and red LEDs provide quick, immediate visual feedback to indicate when the reader is active, or when a tag has been read or authorized.

HOW DOES IT WORK?

The system of this Nedap Antenna operates through a combination of long-range Ultra-High Frequency (UHF) rafio waves, passive tag activation, and automated communication with an access system panel.

The Reader Emits a UHF Signal

The uPass Target reader continuously transmits an Ultra-High Frequency radio signal at 865–868 MHz or 902–928 MHz, depending on the region. Furthermore, its integrated antenna uses circular polarization, so it sends radio waves in a rotating circular pattern instead of a single straight line.

The Tag Enters the Field and Powers Up

When a vehicle approaches the secure perimeter, its credential enters the reader’s adjustable transmission field. Also, the credential may use a windshield sticker, rearview mirror hangtag, or heavy-duty exterior tag.

Passive tags do not contain a battery.
The tag’s internal antenna captures energy from the reader’s incoming UHF radio waves and powers the microchip.
The reader’s circularly polarized antenna lets the tag communicate at horizontal, vertical, or angled positions.

Data Transmission (Up to 15-18 Meters Away)

Once energized, the tag sends a modified radio signal back to the reader through a process called backscatter. Basically, this signal contains unique credential data, such as a Wiegand, Magstripe, or Nedap XS formatted ID.

Standard windshield tags and hangtags support automatic transactions at distances up to 50 feet (15 meters).
Specialized Heavy Duty Tags mounted on metal surfaces extend the read range to 60 feet (18 meters).

Optional Dual-Lane Expansion

If the site requires monitoring both an entry and an exit lane (or an exceptionally wide driveway), an optional external uPass Target Antenna can be connected to the main reader via its TNC input. Additionally, when a vehicle passes the secondary antenna, it captures the tag’s data and channels it directly back through the single primary uPass Target unit.

Authentication and Panel Communication

The reader interprets the incoming signal and sends the tag’s data to the facility’s access control system or parking controller.

Standard setups use interfaces such as Wiegand, Magstripe, RS422, or RS485.
Modern high-security setups transmit data through Ethernet or serial connections with the OSDP v2 protocol. OSDP creates a Secure Channel that encrypts data between the reader and the control panel to prevent wiretapping or skimming.
Nedap-formatted credentials include security protections that prevent unauthorized tag copying and vehicle tracking fraud.

Action and Visual Feedback

After the access system panel verifies the credential data, it opens the gate or barrier. At the same time, the uPass Target provides immediate feedback:

Visual LED Feedback: Built-in blue, green, and red LEDs change color instantly to confirm that the system detected and authorized a tag. The reader can control the LEDs automatically, or the access control panel can control them through active-low digital inputs.
Relay Output: The reader includes a built-in relay output that supports 24 VDC 2A. This relay can directly trigger external hardware or signaling systems after a valid read.
