Rev 09 1 Introduction This document describes the RFID-reading device ARE DT1 LF and the set-up procedure.
Rev 09 2 Startup and testing the reader • Connect the reader with the USB interface from your notebook or pc • The reader is supplied via the USB interface. The supply differs depending on the used port. To reach the maximal reading distance a powerfull supply is essential. A USB hub with its own power supply can deliver this. • In the device manager there will appear a new device (AEG ID Communications Port) • In the brackets you see the port number of the device (e.g.
Rev 09 3.1.1 Entering instructions The protocol format is as follows Command parameter The space character separates commands from parameters and the character acts as command line terminator. For commands without parameter values (e.g. GT ) the character and parameter values are omitted. The command line is as short as this: Command 3.1.2 Output format Generally, every input terminated by is acknowledged by the reader.
Rev 09 3.1.2.3 Output at parameter query Parameter settings can be queried by sending the command without adding a parameter value. Example: Command: MD Output: 2 3.1.3 Blank instuction If a single is input, the reader answers with a single . Example: Command: Output: 3.1.
Rev 09 3.1.5 Upper and lower case The instruction set isn’t case-sensitiv. 3.1.6 Linefeed The reader does never send a linefeed. If you use a terminal program it can add the linefeed. You have to choose the option “displace CR with CR LF”.
Rev 09 3.2 Instructions for the hardware settings 3.2.1 BD – baudrate The command BD enables the change of the baud rate. The settings are directly effective. Input format: BD parameter Output (example): 2 Parameter: PARAMETER FUNCTION 0 4800 baud 1 9600 baud 2 19200 baud 3 38400 baud 3.2.2 EC – Echo The EC command allows to change the echo function.
Rev 09 3.2.3 LED – LED control With the command LED you can control the LED ring of the ARE DT1. Input format: LED parameter Output (example): 1 Parameter: PARAMETER FUNCTION 0 off 1 on 2 Buzzer beeps, LEDs flash final state =initial state 3.2.4 RST – reset With the command RST the reader does a warmstart and loads the saved settings from the internal EEPROM. The antenna field is off after the reset.
Rev 09 3.2.5 HF – Antenna field With the command HF, the antenna field can be set or reset manually. Input format: HF parameter Parameter: PARAMETER FUNCTION 0 Switch off antenna field (this stops automatic mode) 1 Switch on antenna field (this stops automatic mode) 2 Automaticmode, the antenne field is activated by reader to comunicate with the transponder, afterwards it is switched off automatically. Therefore it is not compatible with the password mode.
Rev 09 3.2.6 HID – human interface device/keyboard The command switches the interface ether to HID or RS232 emulation. Input format: HID parameter Output (example): 0 Parameter: PARAMETER FUNCTION 0 RS232 emulation, COM port 1 HID interface, keyboard You have to unplug the device and plug the device in again to use the new setting. Don’t forget to use the command VSAVE to save the new setting. If the reader is in HID mode, you can not send any commands to the device.
Rev 09 3.2.7 KL – keyboard language With the command KL you can configure the language of the keyboard in HID mode. Input format: KL parameter Output (example): 07 Parameter: PARAMETER FUNCTION 07 german 09 englisch 0A spanish 0C french 10 italien 13 dutch 16 portuguese 4B canadian 3.2.8 VER – version With the command VER the reader sends the actual firmware version. Input format: VER Output (example): AEG ID V1.
Rev 09 3.3 Instructions for reading settings 3.3.1 CID – suppression of ID Codes In the MD0 mode with CID=1 only the first of in succession identical transponder numbers is output on the serial interface. The possibly following identical transponder numbers are suppressed, as long as no new valid transponder number is received, processed and output. The get tag command is not influenced by this command. NoReads do not influence the data filtering. The leds are not influenced by this command.
Rev 09 • after a warm start (command line RST ) • after entering the command line CID 1 This causes that the next transponder code is output definitely. Note: The filter function CID picks up the results of the complete reading cycles, while the parameter NID proceeds from the results of single readings! The filter function CID has effect on the serial interface only. 3.3.
Rev 09 3.3.3 NID – Failure Protection NID specifies the number of identical transponder numbers, which have to appear for the result “successful reading“ within a reading cycle. In the setting NID = 1, two successive readings have to show the same transponder number.
Rev 09 3.3.5 LAA – LED automatic activity The leds can be controlled by the reader or over the interface. You can set it up with the command LAA. If the reading settings CN=1, CID=1, CE=1 (when SI=0), MD=0 and LAA=0 are set, the reader beeps and flashes after successful reading. This setting makes sense when reader is used with HID setting.
Rev 09 3.3.7 TOR – maximum reading time TOR is the timeout time for the reader. TOR is used in operation mode 2 as maximum gating time for a reading process. The length of the maximum gating time results from the equation gating_time = TOR * TB. The time constant TB (time base) has always the default value 100ms. Input format: TOR parameter Output (example): 05 Parameter: PARAMETER FUNCTION 00h limits the reading process duration of exactly one reading cycle 01h..
Rev 09 3.3.9 VS – variables show With the command VS the reader shows the settings of the following parameters: BD, CID, CN, EC, MD, NID, TOR Input format: VS Output (example): BD 0 … 3.3.10 SA – algorithm selection With the command SA the algorithm can be selected. Depending on the algorithm, the reader adapts its communication to the transponder suitable for the chip type respectively data format that shall be used.
Rev 09 3.4 General reading instructions 3.4.1 GT – get tag The instruction GT executes one reading and sends back the transponder code of a transponder or the No Read error code (e.g. „FFFFFFFFFF“ oder „XXXXXXXXXX“). Input format: GT Output (example): 0420212E5F 3.4.2 MD – mode of operation There a two modes of operation available. It is possible, that the reader reads constantly or triggered by an instruction.
Rev 09 3.4.4 RD – read page • Start the reader with the command RD plus parameters (plus ). You can read out just one block (with one parameter) or several blocks (with two parameters, first and last block number). • Wait for the answer • Analyse the received answer: 8 characters plus . Allowed characters 0 to F. The NoRead code is set to ( „XXXXXXXX“). The result of the reading process may also be seen at the LED’s. • LED L2 lit, if there was a successful read.
Rev 09 3.4.5 WD – write page The memory of the transponder is organised in blocks, containing 32 bits. The data’s of every single block must be changed separately. • Start the reader with the command WD plus parameters ( plus ). The sent parameter consists of the block address and writing data’s (8 ASCII characters). • Wait for the answer • Analyse the received answer: 3 characters plus . ACK Writing process was successful NAK Writing process was not successful.
Rev 09 4 Operating modes of the reader In the AEG instruction set there are two operational modes defined: • MD 0 - continuous mode • MD 2 - the reading process is triggered by the serial interface In the next capters can you find a detailed functional description. The default mode is MD 2. 4.1 MD 2 - triggered by an software command The master sends the command to read a transponder code. The reader answers with the code or an error code.
Rev 09 TOR exciter processor interface reading cycle reading cycle reading cycle GT NoRead reading process Figure 10: Software triggered reading operation with TOR>0 Please note: The TOR parameter is only active, if the GT-Command is applied. Within the time span defined by the value of TOR no NoRead will be output on the interface! 4.2 MD 0 - continuous reading When operating continuously the exciter is switched on permanently. The reading cycles are initiated periodically.
Rev 09 5 Instructions To avoid any reduction of the reading distance of the reader, the reader must not be brought next to a metal surface (e.g. don’t put metallic sticker to the reader). This could lead to a significant change of the properties of the antenna circuit, which in turn reduces the reading range considerably or causes reading holes! To get reliable readings, the distance between reader and transponder must be within the specified reading volume.
