interface of the PC machine, in the condition of using RS232, KS485 changer for changing, RS485
interface supports all functions that RS232 supports, besides, RS485 a interface for tag data output,
when using theRS485 to upload tag data, it can choose three kinds of modes for transmission.
Active uploading: Uploading data at once when reader read tag
Passive uploading: Non-uploading data when reader read tag, and waiting for mainframe’s order
to read data
Responding transmission: when reader read a tag, reader will upload tag data again and again in
a 10 second space, until receive mainframe orders
Reader RS485 uploading data format as follows:
Frame head
Address
Address
Antenna
Tag data
Frame stern
Checkout
0x02
High byte
Low byte
One byte
8 byte
（
ASCII
）
0x03
One byte
There into, the method of checkout is for the difference checkout of all the frontal bytes
The mainframe to get the order frame format of data is like the following table showing:
Frame head
Identification
Module
Address
Order No.
Frame stern
0x09
0x5B
One byte
One byte
0x83
0x0D
The mainframe to get the response frame is like the following table showing:
Frame
Identification
Module
Address
Order No.
Frame stern
0x09
0x5B

Wiegand interface
Reader supply one Wiegand data interface,, users can choose Wiegand26 or Wiegand34
communication agreement, the data format of these two kinds of agreement is like the following table
showing:
Table one Wiegand26 format
P0
The formal 12 digits
The latter 12 digits
P1
Thereinto, P0 is the even of the formal 12 digits, P1 is the odd of the latter 12 digits 34 format
Table 2 Wiegand34 format
P0
The formal 16 digits
The latter 16 digits
P1
There into, P0 is the even of the formal 16 digits, P1 is the odd of the latter 16 digits
Wiegand interface is composed of 3 lines, the negative pulse of the first line indicates “0”,anothere line
indicates”1”,and the third one is ground electrode. The typical format of every data is like the following
picture showing. Of course, users can settle the data formal of the Wiegand interface according the
special demand of the controller machine
Picture 2 Weigand Signal Shows
In order to improve the of the reliability of data transmission ,the reader supply multi-transmission
function, namely when reading one tag, the Wiegand interface will be multi-transmission in interval in
some time. The transmission times can be 1 to 3, the transmission interval can be set in display
