1.1
Functions & Applications
ONE-900 long range reader is a high performance integrated reader. It can read EPC G2
C1 passive tags at up to 10m, but with moderate size and weight. The reader is
unique at working with not only EPC G2 C1 passive tags, but also our BGC series 2.4GHz
active tags.
The reader aims at providing an efficient and cost-effective solution for automatic vehicle
identification. The dual-frequency reader resolves reading problems through car window
tint/film by using active tags; also it enables most clients to use the lower cost passive
tags.

QUICK CONFIGURATION GUIDE
2.1
Start to Read
ONE-900 can work on three reading modes. By factory default, once a ONE-900 is
connected to the appropriate power supply, it will begin to read tags continuously.
Also
the reader can be triggered to read by a loop detector or infrared detector.
As shown on the left, clients can switch between constant and
trigger mode easily on the reader’s panel.
Notes: after switching the reading mode, the reader should
restart to make the change takes effect.
Otherwise, clients can also program the interrogator to read in response to commands.
3

Trigger Reading
To enable this mode, the reader needs to be wired to a trigger (typically a loop detector or
infrared detector) via its general inputs.
There are two pairs of signal inputs on the reader: IN1+/IN1-, and IN2+/IN2-. Only IN1
ports are applicable for this function. For testing purposes, you may short IN1+ with IN1-,
which will generate a valid trigger signal. Notes: when trigger signals varnish, ONE-900
will continue to read for 2 seconds.
Installers can pull out the terminal blocks on the reader’s interfaces for easy wiring with
external devices, and then insert back the terminal blocks to complete connection with the
reader (shown below).
Pull out terminal blocks

Command Mode
In this mode, ONE-900 will remain on standby until it receives a command from PC.
For example, the PC sent a read command to a ONE-900, and then the reader will start
to read and make a return to the PC. The command mode is to facilitate clients to
integrate the reader.
When a reader is working, it should emit LED and audio signals according to its operation
status.

Turn On/Off 2.4G
ONE-900 is a hybrid reader. But the 2.4G reading function can be turned on or off by
pushing the toggle switch 2 on the reader’s panel.
Notes: after push the switch, the reader should be restarted to allow the new
settings to take effect.

2.2
Setup Frequency
ONE-900 can operate on either fixed frequency or FHSS mode.
As shown above, switch 3, 6, 7, and 8 on the reader’s panel is to set the operating
frequency of the reader. There are eight frequency channels available on the reader. It
can be set to operate on any of the channels or automatically hops between channels. By
default, the reader should operate on 922.625MHz.

Transmit Data
ONE-900 can transmit data to a controller via wiegand (26/34), or to a PC via RS232 or
RS485 interface. By default, ONE-900 should upload data via wiegand 26. Clients can
set to use other interfaces in the example software provided by the manufacturer.
Once the settings have been saved to the reader, the reader should be restarted to
activate the settings.


Wiegand 26
There are clear interface definitions on the reader’s panel to enable connection with a
controller.

Wiegand 34
There are clear interface definitions on the reader’s panel to enable connection with a
controller.

RS232
If the reader is set to transmit data via RS232, it will upload data actively to an external
device when it reads a tag.

RS485
The reader can be set to upload data actively or passively via RS232 to external devices.
With built-in RS485 protocols, a reader can connect to a controller or PC directly. Also
multiple readers can be used to build a network.
For more details about protocols and data formats, please refer to part 6.
Please note that the maximum data transmission distances of the interfaces are different.

Adjust Reading Ranges
A standard ONE-900 reader can work with both EPC G2 C1 passive tags and active
tags. With a passive tag, its reading range can be up to 10m, depending on tags and/or
change the output power of the antenna. Its reading distances are more flexible on active
tags.
As there are more tag models selectable, also clients can adjust the ranges for
2.4G on the hardware easily. Below are further explanations on setting the reading ranges
for 2.4G active tags.
As mentioned in 1.3, each of our major active tag models has several sub-models, shown
by suffix e.g. -12, -70.
These sub-models enable a reader to have variable minimum and
maximum adjustable ranges. For example, to present both BGC-S-12 and BGC-S-70
tags in front of a BG-245-K, the min. adjustable range for BGC-S-12, should be around
3-5m, while the min. adjustable range for BGC-S-40 can reach 20-30m. The maximum
adjustable range on a -12 tag can be 15-20m, while on a -40 tag, it can make 40m and
more. For parking applications, however, -12 series tags should fit for most systems.
6
On the same tag, clients can still set different reading ranges by rotating the embedded
potentiometer in the reader.
Potentiometer
Clients can use a small screwdriver to rotate the potentiometer clockwise or counter
clockwise, accordingly the reading range becomes longer or shorter. At the adjustable
extreme, you can hear a low spring-like sound, after that, further rotation in the same
direction would not change the reading range any more. There are around five valid
rounds between the minimum and maximum adjustable position.

QUICK INSTALLATION GUIDE
3.1
Mount Reader
ONE-900 can be mounted on either a pole or wall. The reader is equipped with a linear
horizontal antenna with limited readable angle. It should be installed at a suitable height
and angle towards the ground, so as to give the optimal performance.
A series of factors can affect the reader installation height and angles, including the
reading distance, width of the lane, types of vehicles, etc. The figure below shows a
typical installation for your reference.

Control Peripherals via GPIOs
ONE-900 has 1 pair of relay outputs. Clients can program the reader to send close or
open signals to the contact point when it reads a valid tag. In this way the reader is able to
control a peripheral directly, e.g. barrier, alarm.

Notes: the relay output can only control an equipment powered by maximum
110V/0.5A AC or 24V/1A DC power supply. To control a 220V equipment, an external
relay should be used.

TROUBLE SHOORTING AND MAINTENANCE
4.1

Troubleshooting
I push the switches on the reader but it does not work. Why is that? For example, I’ve
switched off the 2.4G function, but it continues to read active tags.
You must restart the reader after pushing a switch, so that the new settings can take
effects.

Why the blue LEDs on my reader never flash and the reader cannot read tags?
Please check with its reading mode settings. Only at the constant mode, the reader will
read tags automatically. At the trigger mode, however, the reader should receive a
triggering signal to start reading.

My reader can hardly read a tag or the distance shorter than expected, what is the
reason?
The reader is equipped with a linear horizontal polarization antenna. So tags should be
placed in a way where its polarization direction is in line with that of the reader’s antenna.
If you consider the reading ranges not so well on a tag, please rotate the tag by 90º and
try again.
Also in one of following situations, the reading distance can be shortened even there is no
problem on the reader: tags are close to or have direct contact with human body, metal
8
screen, or liquid obstruct between reader and tags.

Why the reading distance of my reader on windshield tags is so short in the open air?
Windshield tags, as the name suggested, should be attached on window so as to get
optimal reading effects. For simulation, you can fix a tag on a piece of glass with crystal
tapes, and try again with the reader.
4.2
Maintenance
There are a few tips to get the optimal performance out of the reader.

Always use the power adaptor provided by the manufacturer, or consult the supplier
for a compliant power adaptor from a third source.

DO NOT disassemble the reader. If there is any problem on the device, please return
the supplier for repairing.

COMMUNICATION PROTOCOLS AND DATA FORMATS
Here we’ll explain further about the protocols that clients can use on a ONE-900 for
data transmission and relevant data formats.
6.1
Wiegand
Wiegand protocols are used to connect a reader with a wiegand controller. This interface
supports one-way data transmission, namely, the reader can send data to the controller,
but cannot receive data via wiegand ports. Wiegand interface contains two data lines and
one ground line.
For any binary data, e.g. 01010101B, the protocols send out 0 or 1 in separate lines. That
is to say, the W0 line sends 0 only, and the W1 always sends 1. According to the data bits
transmitted per frame, wiegand protocols have two types: wiegand 26 and wiegand 34.
To ensure a controller to receive data via wiegand, the ground line of the reader should
always be connected to the ground port of the controller, or the negative electrode of the
power supply of the reader.

Output Waveform
The default pulse width time is 100us, pulse interval time is 1.0ms, and frame interval is
no less than 800ms.The output waveforms can be changed in software.

Data Formats
Wiegand 26
This protocol transmits 26-bits data per frame, and only 24 bits among which are valid
data. We define the 24 bits to correspond to the last three bytes of a tag ID. Details are as
below:

6.2
RS485
RS485 protocol enables a reader to communicate with a remote controller or PC. It
supports two-way communication between the reader and external devices, or the reader
can be set to transmit data one-way to an external device.

Upload
Here upload refers to data transmission from the reader to an external device.
Upload includes data upload and command upload. Data upload is to deliver the tag ID or
antenna data to a controller or PC, while command upload deals with the command and
response between a reader and external devices.
