1Introduction
The uPASS Access is an ultra-small UHF RFID reader for handsfree door access.
Based passive UHF technology, people are identified up to 2 meters (6.5 feet).
Typical applications include hands-free door access in hospitals, office buildings, gated communities, care homes
and universities.
The uPASS Access is ideal for door post mounting at a height of about 1.5 meters (5 feet). It can be installed directly
onto a wall next to a door, without requiring additional mounting accessories. The reader is IP65 rated, so it can be
used indoors as well as outdoors. Installation cable 5 meter (15 feet) is included.
The uPASS Access supports a variety of industry-standard communication interfaces and protocols, such as RS485,
Wiegand, Magstripe (clock & data) and the Open Supervised Device Protocol (OSDP). This enables seamless integration
into any existing or new access control or parking system.
1.1 Firmware versions
The uPASS Access reader supports different firmware versions. Below an overview of the available firmware versions
and their key features.
Standard firmware
•STANDARD ASCII (CR/LF) protocol.
•Wiegand.
•Magstripe ISO7811/2 (clock & data).
OSDP firmware
•OSDP according to the SIA OSDP v2.1.7 standard.
•Secure channel protocol supported.
•LED and buzzer control through OSDP commands.
•General purpose input (3x) and outputs (2x).
OSDP (Open Supervised Device Protocol) is an access control communications standard developed by the Security
Industry Association (SIA). The OSDP protocol specification can be obtained from the website;

1.2 Supported tags
Any EPC Class 1 Gen 2 tag is supported by the uPASS Access.
NEDAP formatted UHF tags can have the following formats:
•NEDAP UHF Wiegand tags
These tags will contain all Wiegand information including facility code and parity bits. All Wiegand formats can be
supported. The reader transparently sends this information via the Wiegand outputs. There is no need to change
any DIP-switches or configuration settings. See chapter 3.2.3 for wiring details.
•NEDAP UHF Magstripe tags
These tags will contain all magstripe information. The reader transparently sends this information onto the
magstripe interface. There is no need to change any DIP-switches or configuration settings. See chapter 3.2.4 for
wiring details.
•NEDAP UHF XS tags
These tags are especially programmed in the same format as our TRANSIT tags (Compact-Tag, Window-Button
and Heavy-Duty-Tag). The tags will have a customer-code and id-number.
The reader will modulate the tag-info onto the Nedap antenna interface output, which can be connected to NEDAP
AEOS access control hardware such as the AP1001.

1.3 Tag security
EPC (Electronic Product Code) tags were introduced as a possible successor to the barcode with added functionalities.
The tag emits its EPC in plain text. This makes the tags vulnerable to cloning and counterfeiting attacks.
There are a few security measures possible against tag cloning.
TID check *
EPC tags contain a data field known as the Tag Identifier (TID). At the discretion of the EPC tag/card manufacturer, the
value is be factory programmed and locked, ensuring that tags have a unique identity and cannot be cross-copied.
NEDAP UHF tags support a locked serialized TID and the uPASS reader can be configured to read the TID data field.
EPC passwords **
EPC tags have 2 passwords. NEDAP has implemented a two-way authentication anti-cloning method using these 2
passwords. This feature is supported in combination with all NEDAP UHF tags.
EPC Gen2 V2 secure authentication ***
The EPC Gen2 V2 tags support a secure authentication method.
This is the best possible anti-cloning measure available.
The authentication data transmitted between tag and reader are enciphered using AES128 bit encryption. The
encryption keys are diversified using the programmed EPC number to ensure that the keys are different for each tag.
Required is that the tags contain an EPC Gen2 V2 compliant RFID chip. Refer to NEDAP uPASS how to order guide for
product numbers.
* Possible for any UHF tag.
** Possible for all NEDAP UHF tags.
*** Possible for all EPC Gen2 V2 tags.
Tag security is not evaluated by UL.

Default baud rate is 9600. This can be changed using the UHFTOOL software.
OSDP firmware
The uPASS Access reader has implemented the OSDP protocol including the Secure Channel Protocol.
Default baud rate is 9600. This may be changed using the OSDP_COMSET command.
Perform a firmware update to change from STANDARD to OSDP (or vice versa).
The firmware update procedure is described in chapter 5.4.
RS485 point-to-point communication
Termination resistors (120 Ω) are recommended to prevent unwanted signal reflections on long RS485 communication
lines. The resistors should be installed at both ends of the communication line.
Figure 4: RS485 point-to-point communication (uPASS Access Rev. C)
The uPASS Access reader models before 2020 (Rev. A/B) have a fixed termination resistor. This means you don’t need
to install a separate termination resistor. See Figure 5.
Figure 5: RS485 point-to-point communication (uPASS Access Rev. A/B)
Notes
•Use shielded twisted pair cable when extending the RS485 wiring beyond the standard 5 meter cable.
•Maximum RS485 cable length 1200 meters (6000 feet).

4UHF frequencies
4.1 Radio regulations
The uPASS Access reader operates on the 860 – 960 MHz band. Regulations in this band are not standardized world-
wide. Generally the regulations can be divided into several regions.
Per region a specific frequency band is available. This frequency band is divided into frequency channels. If local radio
regulations require frequency hopping (FHSS), then the uPASS Access automatically selects and uses the available
channels.
4.2 Frequency channel selection
If no frequency hopping is required, you should select an available frequency channel manually. This can be realized as
described below. Select an available frequency channel to achieve the best performance and to avoid interference from
other readers or equipment.
Use UHFTOOL to setup the frequency channel selection. See for more details chapter 5.3.4.
