How to Use

Operating Reader via Demo Software

  • Once connected with the host, open the COM port. If reader connects the COM port we can see the port display in the place.
  • After the demonstration software goes to 57600 bps by connecting the port and written communication, the connected port will be in the open state. The baud will be automatically select from 115200bps, 57600bps, 38400bps, 19200bps, 9600bps if success or error message will pop up.
  • The Reader defaults to setting the address as a hexadecimal; the output power is between 0 to 30db
  • Reader’s default baud rate is 57600bps. After changing the baud rate, the reader uses the new baud rate until power off.
  • The process of each maximum Inventory scan time is 10*100ms. If demo software sends the inventory order, it will wait 30*10ms for the reader to response and exit. Only when inventory completed, the reader can respond to the other new command.
  • Frequency: In different places, the radio requires the different rule. Users can follow the local situation and choose to read tags which have more sensitive frequency range. In single frequency operation, user set the two frequencies to the same value. By frequency hopping operation, user set the two frequencies to the different value.
  • Users can monitor the internal temperature via the built-in temperature sensor to avoid reader overheating.
  • Each time when the reader identifies a Tag’s UID, the buzzer will sound a short beep. When the reader successfully reads or writes to a label, it will have prompt.
  • Four Antennas are used in the GAO216022. The user can select multiple antennae to work together to sense the tag.
  • Two tag protocols ISO18000-6B and EPCC1G2 are used in the GAO216022. EPCCIG2 has 4 memory spaces and can store different manufacturer’s details such as Electronic product code, unique tag ID, user area and Password on each card’s IC. ISO18000-6B has only one memory space which holds a unique tag id.

Communication Interface

  • RS232, RS485, TCPIP and Digital Input/output are the four interfaces used for communication.
  • GPIO Port: It has 8 general purpose output pins. Other pins are used as GND for ground terminal, NO for normally open terminal for relay, NC for normally closed terminal for Relay, CM for common terminal for relay, TGIN for trigger input and R+ and R- is used for RS485 interface
  • RS232 Port: This has several pins. GND is used for Ground Terminal. TXD terminal used for Data to be transmitted over the communication link. RXD terminal used for data that has been received from the communication link.

LED Indicators: LED indicators indicate the Power LED is ON, Tag detection LED is ON if sense the tag, Device LED is ON if the device is connected and the working indicator of four Antennas.

 Active mode Operation

  • In active mode, default to settings pulse Interval, EAS accuracy and trigger time.
  • When the Reader reads the tag if EAS alarm detects the unknown user the Relay action releases in 3s.
  • When in active mode, communication succeeds through protocol and interface.

EPCC1-G2 Operation

  • Select Query is executed first before doing any operation to tags. The query command will be sent every 50ms.
  • We can read the data of tag, write the data of tag, block and erase the data, set the read and write protection, modify the password and block the user of the tag. To read the data and write the data, a maximum distance is in effect.

ISO18000-6B Operation

  • Access operation only for the selected tag.
  • It can read the data of tag, write the data of tag and permanently write protect. We can lock designated byte.

If the reader is connected via TCP/IP, you need to operate these following steps,

  • Ensure that an RJ45 Ethernet Card has been installed in the PC.
  • Ensure that PC and reader in the same network segment.
  • Once the device is connected, Login by entering the default username and password.
  • Enable the Serial Port for the connection protocol TCP.
  • Default settings of Network as follows:

IP addresses:


HTTP Server Port.: 80

To change Reader’s network

  • Get the 216022 reader connected directly to a server PC via the default serial cable.
  • Run the demo utility.
  • Make sure the “COM” is being checked, then  “Open Com Port”
  • In the “TCPIP Serial Config” at Mode Change operation if we click GOTO, make sure the “GOTO: Successfully” is shown on the status bar.
  • In the GET operation, the current network parameters stored in the reader will be displayed.
  • Change reader’s network parameters such as port number, IP address, gateway address, etc. Set operation set the parameters and   “Set:  Successfully” is shown on the status bar.
  • Save and Restart the device to take new settings effect.
