Notes:
a.
The black wire of the BG-245/W must connect with the GND port of the
Wiegand controller
; otherwise, the reader would not upload data to the controller.
b. By default, the white wire and green lines are welded together to enable the reader
to read tag.
c. To enable reader to work in a trigger mode, i.e. begin to read only when a car
arrives, user can set apart the white and green lines, and connects them separately to
the N/O and COMMON ports of the same channel in a loop detector.
2.2 Adjust Reading Ranges
The reading range is adjustable from 1 to 170 meters and depends on the types of tags.
This can be done by adjusting the potentiometer at the bottom of the antenna (refer to
the picture).

Encoder
By default, BG-245/w reader should transfer every tag ID immediately once it reads a
tag. In some cases the system needs to avoid repeated tag IDs, so as to ensure the
operation of the system. BG-245/w can be set to meet the requirements.
There is an embedded encoder in the bottom of the reader. Clients can shift the
decoder to define a specific interval, so that within the interval the reader would only
transfer unique tag IDs they read.
The encoder provides ten options of intervals. Standard options are from the shortest
0.8s, to the longest 70s. Details of the options are as below:
Option
0 1 2 3 4 5 6 7 8 9
Interval
0.8S
5S 10S 15S 20S 30S 40S 50S 60S 70S
