2.2.1 RS232
The reader provide RS232 communication interface for cooncting communication with control
nainframe((commonly the PC machine),the data format of the RS232 interface is 8 data bits, a
star bit and a stop bit, without parity bit; 9600，19200，38400，57600 and 115200 are the choices
for data modulus..RS232 communication interface support the fitting parameter ,demonstration
program, all the second exploitation bag function of the single communication of the reader.
2.2.2 RS485
MR series provide RS485 communication interface,, which can connect with interface of the PC
machine, in the condition of using RS232,RS485 changer for changing,,RS485 interface supports
all functions that KS232 supports,besides,KS485 a interface for tag data output, when using
theRS485 to upload tag data,,it can choose three kins of modes for transmission.
Initiative uploading: Upload data immediately when reader reads the tag.
Passivity uploading: It doesn’t upload data when treader reads the tag,but wait until the
mainframe to fetch data.
Reaponsion transmission:After reader reads aon tag, it will upload data repeatedlyuntil receives
the response velemen from the mainframe t
How RS485 uploads data format is like the following tables:
frame
head
address address entenna Tag data frame stern checkout
0x02 High
byte
Low byte One
byte
octor（ASCII）
0x03 One byte
Thereinto,the method of checkout is for the difference checkoutt of all the frontal bytes
The mainframe to get the orderframe format of data is like the following table showing:
Rame head Identification module address Order No. framestern
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 Oreer NO. frame stern
0x09 0x5B One byte One byte 0x82 0x0D
2.2.3 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
P0 The formal 16 digits The latter 16 digits P1
Thereinto,“ P0” is the even of the formal 16digits,“ P1” is the odd of the latter 16 digits
Wiegand interface is composed of 3 lines, the negative pulse of the first line indicates
