8.4 Configuring the reader
When the reader is in autonomous mode, the following configs can be done: Communication type; Read or standalone (idle); Read power; Read time; Standalone time; Tag EPC id decodification type; Read operation of the tag memory bank; EPC Gen2 protocol parameters BLF; Tari; Encoding; Session; Target; Q (collision avoidance); Access password; Character that separates the fields of the result string; String result end of line type; Keyboard emulation digitation speed; RSSI filter; Show or not the RSSI value of the read tag; Show or not the amount of reading of the read tag; Read tag warning sound; Check the internal temperature; Decodification type of the PA tag read; Show or not which antenna read the tag.
8.4.1 How to set up the reader?
The reader in Autonomous mode must be configured through ASCII commands sent through the port serial created in the Operating System when the reader is turned on.

NOTE:

To know which serial port the reader will respond to, please consult 7.1 Turning on the reader.

8.4.1.1 Operating logic
Reader configuration via ASCII messages works with the Message/Response structure: A. The external host send a command for the reader; B. The reader interprets and execute the command in the message received; C. The reader answers the external host;
Messages and replies use ASCII characters with a carriage return terminator. Messages can be in uppercase, lowercase, or both.

The reader echoes each character typed into the serial terminal and each newline the NOTE: reader sends the character “>” to indicate the cursor.

8.4.1.2 Messages and answers sintaxe
Below is the syntax of the messages from the Host to the Reader:

COMMAND VALUE COMMAND

Change the command/parameter value. Reads the command/parameter value.

WARNING:

Only one value must be passed to each command, the reader does not will accept more than one value per command.

Below is the syntax of the response messages from the Reader to the Host:

RESULT

Returns the result of the last execution command sent to the reader.

8.4.1.3 How to send the commands to the reader? (Windows)
Reader settings in Autonomous mode can be performed through a software terminal emulation. The best known free and open-source code is Putty whose Download link see below. https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html To config the Putty follow the steps:
1. Open the Putty and select “Connection type:” “Serial”, “Serial line” the port that the reader generated and “Speed” 115200.

2. Click in “Open” to open the terminal screen for typing commands.

8.4.1.4 How to send the commands to the reader? (Linux and Mac OS)
On Linux operating systems you can also use Putty as explained above for the Windows. For Mac OS and Linux you can use the “screen” program as shown below.

NOTE:

To know which serial port the reader will respond to, please consult 7.1 Turning on the reader.

(Mac OS) $ screen /dev/tty.usbmodemXXXXXX 115200 Where “XXXXXX” is a unique identifier number generated by the operating system.

(Linux) using screen.

NOTE:

On linux to have permission to use the serial port, run the command with permission of super user (sudo) or add your user to the dialout group using the following command: $ sudo usermod -a -G dialout $USER To take effect, you must restart the system.

To connect using the screen: $ screen /dev/ttyACMx

8.5 Configuration commands
8.5.1 Important tip
It’s not always easy to remember the command name or accepted values, that’s why there is the command help which if executed with no value lists all commands supported by the reader and to get details of a specific command just type help command, this is a quick way to access the scanner’s configuration information. Below are images of the help command.

8.6 Changing from Autonomous mode for Transparent and vice versa.
To change the reader’s operating mode, the following options can be used: A. Use the readmode command, examples: a. The reader is in Autonomous mode and the command “readmode transparent” is sent,in this way the reader enters the Transparent mode of operation. b. The reader is in transparent mode and the $ off command is sent, so the reader enters Autonomous mode of operation with hid interface.

NOTE:

When in transparent mode, the reader does not echo characters typed into the serial terminal.

B. Use the “Caps Lock” key (Windows and Linux only), for example: a. Close any serial communication with the reader; b. To switch between one operating mode and another, just quickly click 5 times in sequence the CapsLock key and check the reader LEDs to see the change.

WARNING:

The Caps Lock shortcut for changing the operating mode only works if and only if the reader’s serial port is not connected (not being used by any Software).

NOTE:

When the reader’s communication interface is RS-232, switching the operating mode must be done exclusively by the “readmode” command.

8.7 Same tag read rate
The same tag read rate can be controlled by the following commands: gen2session gen2target rfon rfoff
The commands mentioned above change the parameters of the UHF EPC Gen2 protocol and have an effect on the communication between the tag and the reader. Combinations of values for the Tag’s Session and Target reflect how often a tag that has already responded to an inventory will respond again, in other words, how fast is the replay reading a tag. Examples:
A. I would like to read only once the EPC id of a tag and that the same EPC id is not repeat while the tag is in the reader’s reading field. Configure as follows: gen2session s2 gen2target a
B. I would like to repeatedly read the same tag while it is in the reader’s reading field. Configure as follows: gen2session s0 gen2target ab
In this case, what will determine the read repetition rate are the rfon and rfoff commands, i.e. the sum of the times will dictate the repetition rate. Highest repeat read rate possible is every 50ms: rfon 50 rfoff 0

WARNING:

The tag read rate can be much faster than the tag read rate. sending the results by keyboard emulation (hid), that is, if the rate chosen is high and the chosen interface is the emulation of the keyboard, the reader will store the reading result and keep sending even after the tag is removed from the reading field.

With the AcuPad-50 Mux reader it is possible to read any memory bank of the EPC gen2 tag, (reserved, epc,tid and user), just configure the tagop command in which bank you want to read together with the initial position and size of the data (in word) that you want to read. The syntax of the tagop command is explained in detail in 8.5.4.13 tagop – Tag read operation Examples:
A. Read the tag’s entire TID bank plus the EPC id in hex: tagop tid:0:0 epcdecode none Example of reading two tags with different TID bank sizes:

B. Read from the TID bank 4 words a skipping the first 2 words and decode the EPC id from the table ASCII: tagop tid:2:4 epcdecode ascii Example of reading two tags:

In addition to the TID bank, the RESERVED, USER and EPC banks can also be read together with the EPC tag id.

NOTE:

The unit of count in the EPC Gen2 standard is word, which is equivalent to 2 bytes or 16 bits.

NOTE:

For the Reserved bank, if the tag has an access password recorded other than 0x00000000, the tag password must be configured in the reader by the command gen2accesspassword.

NOTE: More details on the commands in 8.5 Configuration commands.
