2.4. Adjust Reading Ranges
This function is for active tag only. A standard BU-900R-K reader can work with both
ECOMPUTER 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.
Each of our major active tag models has several sub-models, shown by suffix e.g. -12, -40 and
-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 BU-900R-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
12m, while on a -40 tag, it can make 40m and more.
On the same tag, clients can still set different reading ranges by rotating the embedded
potentiometer in the reader.
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.
2.5. Switch Board
BU-900R-K can work on three reading modes. By factory default, when a BU-900R-K 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.
Users 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.
2.5.1. 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 input. For testing purposes, you may short IN+ with IN-, which
will generate a valid trigger signal. Notes: when trigger signals received, BU-900R-K will
continue to make reading for 2 seconds.

Users can pull out the terminal block on the reader’s interfaces for easy wiring with external
devices, and then put it back to complete connection with the reader (shown below).
2.5.2. Command Mode
In this mode, BU-900R-K will remain on standby until it receives a command from
COMPUTER. For example, the reader will start to make readings when the COMPUTER sent
a read command to a BU-900R-K, meanwhile, the reader will return a confirm data to
computer as confirmation. 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
Notes: after the switch, please restart the reader.
3. READING INSTALLTAION
A BU-900R-K can be fixed in sites in any way they see fit. Installers are recommended to order
a standard pole mounted bracket from the manufacturer to install the reader. Below is our
mounted bracket.
The reader 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.

4.2. Reader & EPC Card Alignment
The following criteria must be satisfied to achieve the optimum read reliability:
Polarization of the tag and BU-900R-K must be aligned in the same direction.
The installed tag must be in a direct, unobstructed line of sight to BU-900R-K. All the
materials reduce the RF signal. Metal and water can cause the significant problem by
reflect and absorb single.

5. TROUBLSHOTTING AND MAINTENANCE
5.1. Troubleshooting
Q: Why the blue LED on my reader never flash and the reader cannot read tags?
A: 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.
Q: My reader can hardly read a tag or the distance shorter than expected, what is the
reason?
A: 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 screen,
or liquid obstruct between reader and tags.
Q: Why the reading distance of my reader on windshield tags is so short in the open
air?
A: 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.
5.2. Maintenance
There are a few tips to get the optimal performance out of the reader.
9
1. Always use the power adaptor provided by the manufacturer, or consult the supplier for a
compliant power adaptor from a third source.
2. DO NOT disassemble the reader. If there is any problem on the device, please return the
supplier for repairing.
