RS485 :
RS485 can be connected with PC interface using the RS232-RS485 converter.
With this mode, RS485 interface supports all the functions as RS232 .
GPIO Port :
This reader support 4 output port （0-3）, user can set it to high or low level :
(when power up default is high level output）

Tag operate
ISO18000-6B Tag :
 Multi-tag identification: search all the tags in the detection range and read the
UID of 8 bytes.
 Multi-tag reading: search all the tags in the detection range and read the 8
bytes data of the appointed address
 Single tag writing: write one byte data in the appointed tag address.
 Single tag locking: lock the data of the appointed tag address. After that, it
can not rewrite.
 Single tag locking and inquiring: inquiry the locking state of the appointed
address.
EPC GEN2（ISO18000-6C）tag
 Multi-tag identification: search all the tags in the detection range and read the
EPC. (supports 96 bits EPC)
 Single tag initialization: define the length of EPC, generally 96 bits.
 Single tag writing: write the EPC of tag, one block (16 bits) one time.
 Single tag locking: lock the EPC of tag. After that, the EPC of tag can not be
rewrite.
 Single tag killing: kill tag. After that, the tag can not be used again.
Operation mode
Command operation mode:
The reader and the controller can communicate through RS232, RS485 or Ethernet.
This working mode supports all the functions that secondary development provides.
