1. Introduction 
The AY-U920BT is a UHF and Bluetooth reader that is available with versions in 
both UHF frequencies (865-868 and 902-928 MHz) and supports Bluetooth 
BLE frequencies and protocols. Two associated apps for iOS and Android 
smartphones made by Rosslare can be used with the reader – BLE-ID credential 
app and BLE-Admin configuration app – for programming operational settings. 
The reader is waterproof (IP65) and is suitable for use in a wide range of RFID 
applications, such as transport management, vehicle management, car 
parking, production process control, and access control. 
The reader supports the following functions: 
 Reading UHF hard credential 
 Reading BLE soft credential 
 Transmitting credential ID to the controller 
 Acting based on controller’s input (allowing access or not) 
 Self-update 
 Reconfiguration provided by credential (soft or hard) or by PC SW 
The AY-U920BT series includes the following models: 
 AY-U920BT-US: 902–928 MHz (America) 
 AY-U920BT-EU: 865–868 MHz (Europe)

3. Mounting 
Installing an RFID reader adjacent to metallic surfaces might alter the reader’s 
specifications. To diminish this interference, use a plastic spacer when mounting 
the reader. 
3.1 General 
There are two methods that can be used when installing the reader. 
 1-Shaped Stand Bracket Side-Loaded 
 L-Shaped Stand Bracket Top-Loaded 
Each installation method is selected based on application requirements and 
actual location. 
3.1.1 1-Shaped Stand Bracket Side-Loaded 
In this method, the stand pole should have a diameter of between 50 and 
60 mm (2 to 2.4 in.) and a height of 2.2 m. The pole should be made of 
stainless steel with a thickness of at least 1.2 mm (0.05 in.). 
Use the bracket contained in the package box to mount the AY-U920BT reader 
to the top of the stand pole depending on actual vehicle type (mainly large car 
and small car) (Figure 1). 
Figure 1: 1-shaped Stand Bracket Side-Loaded 
Adjust the height from the center of AY-U920BT reader to lane level to be 
around 2.0 m (6.5 ft).

3.1.2 L-Shaped Stand Bracket Top-Loaded 
In this method, the L-shaped stand pole should have a diameter of between 60 
to 80 mm (2.4 to 3.1 in.) and a height of 4.2 m (13.8 ft). The pole should be 
made of stainless steel with the thickness of at least 1.2 mm (0.05 in.). 
Use the bracket contained in package box to mount the AY-U920BT reader to 
the rail near the center of the lane (Figure 2). 
Figure 2: L-shaped Stand Bracket Loaded 
Adjust the height between the rail and the ground to between 3.5 to 4.0 m 
(11.5 to 13 ft), depending on the height of vehicle.

3.1.3 Adjusting the Azimuth Angle of Antenna 
The angle of inclination with the ground plane of the antenna should be 
approximately 60° to 75° (Figure 3), while the deviation angle of the antenna 
should be biased towards the lane direction (Figure 4).

Wiring 
12  AY-U920BT-US Installation and User Manual 
4. Wiring 
The units are supplied with a 5 m (16.4 ft) 10-conductor pigtail with exposed 
wires coated with solder (see Figure 5). 
Figure 5: Wiring Colors 
To connect the unit as a reader to an access control unit: 
1. Select the appropriate connections according to Table 1. 
2. Prepare the controller cable by cutting its jacket back about 3 cm (1¼") 
and strip the insulation from the wires about 1.3 cm (½"). 
3. Splice the reader’s pigtail wires to the corresponding controller wires and 
cover each joint with insulating tape.

AY-U920BT-US Installation and User Manual 13 
4. Trim and insulate the ends of all unused conductors individually. Do not 
short any unused wires together. 
• The individual wires from the reader are color coded according the Wiegand 
standard. 
• When using a separate power supply for the reader, this supply and that of 
the controller must have a common ground. 
• The reader’s cable shield wire should be preferably attached to an earth 
ground, or a signal ground connection at the panel, or the power supply end 
of the cable. This configuration is best for shielding the reader cable from 
external interference. 

Operation Instructions 
14  AY-U920BT-US Installation and User Manual 
5. Operation Instructions 
After wiring the unit to a controller (POWER, GND, D0, D1), you should test 
the reader. 
To test the reader: 
1. Power up the reader. One beep is emitted and then it begins an auto-
calibration procedure. After 2 seconds, the reader enters working mode. 
2. Present the appropriate type of credential to the reader. A short beep is 
emitted, indicating that the credential is read properly.
