instruction can be used to check the current parameter value for instructions that carry a parameter.

• Input Instruction Answer: Parameter

BD

BD
Baudrate parameter sets the baudrate for ARE i2.0x. Please Note: Standard parameter is 19.200 baud.

Input format: BD Parameter e.g. BD2

Output (example): Baudrate 38.400 baud

Parameter:

VER

• VER – Reader firmware version
• VER is used to get the actual reader firmware version.

Input format: VER

TOR

TOR – Timeout Reading
After a read is triggered by GT, TOR is a time during which ARE i2.0x HF continuously tries to read a transponder UID without the need to be triggered by the host again. This limits bus traffic considerably. Once a successful read is performed, continuous reading stops immediately regardless of time and the transponder UID is transmitted to the host. If reading is not successful, a no read (XXXXXXXX) is sent to the host after TOR time has expired. The chosen parameter for TOR is sent as acknowledgement.

Input format: TOR Time parameter e.g. TOR50

Output (example): 50

Parameter:

• A TOR value of 50 equals 50 x 100ms = 5000ms = 5 sec.
• It is recommended to set the TOR value to the amount of time it takes in a dynamic situation for the transponder to travel over ARE i2.0 HF. This maximizes the number of possible reads, to compensate for EMV noise in the vicinity.

GT

GT – Get Tag
GT is used to retrieve the transponder UID. GT uses the TOR parameter to define the time during which the reader continuously looks for a transponder without the need for the host to get involved.

Input format: GT

Output (example in case of a successful read): E0080100002B3706

Output (example in case of no transponder in the field): XXXXXXXX

RD

RD – Read the transponder memory page
RD is used to read an individual memory page from a transponder in the field. RD uses the TOR parameter during which the reader continuously looks for a transponder without the need for the host to get involved. Please see the datasheet of the transponder for sa pecific memory map. Page is input as a hex number.

Input format:

• RDpage
• RD 1

Output (example in case of a successful read): 1234567812345678

Output (example in case of no transponder in the field): XXXXXXXX

WD

• WD – Write transponder memory page
• WD is used to write to individual memory pages of a transponder in the field. WD uses a TOR parameter during which the reader continuously looks for a transponder without the need for the host to get involved.

Please see the datasheet of the transponder for a specific memory map. Page is input as a hex number.

Input format:

• WDpagedata
• WD 5 12345678ABCDEF78

Output (example in case of a successful write): ACK

Output (example in case of no transponder in the field): XXXXXXXX

MD

MD – Read mode
MD is used to either read the chip UID once per trigger by the host (e.g GT command) or read the chip UID continuously after a trigger by the host until the mode is switched back to a single read

Parameters:

Input format:

• MDparameterCR>
• MD 0

Output (example): 0x1

CID

• CID – Filter same UID numbers to transmit only once via interface
• CID is used to filter multiple read transponder UID to transmit only once via the interface. There needs to be one different Transponder UID read before the same number will be transmitted again.

Example error #02 (wrong parameter)

The error code is comprised of a two-digit ASCII-coded number.

The following table displays possible error messages:

LED instruction set

• Is i2.0 HF employing a multi-colour LED to signal different modes?
• Basically below colors can be created:

The user can choose any colour apart from white. This color is reserved for setup help functionality as described below.

The following modes use a distinct colour each.

• Standby (LSTB)
• Reading (LGT)
• Transponder number successfully read (LRD)
• No Read (LNRD)
• Error (LERR)
• Process active (LPA)
• Process status (LPS)
• In addition, the user can choose to switch on the LED permanently or flashing.

The following instruction set is used:

ModeRGBFX

• R – Red
• G – Green
• B – Blue
• F – Flash
• X – LED functionality ON or OFF for this mode

Allowed parameters are 1 (on) or 0 (off)

Default colours are shown with the instructions.

LED Standby (LSTB)
The standby colour is Cyan, no flash.

Input format: LSTB 01101

Output: 01101

Standby mode is active if no other instructions are carried out.

If the Standby LED is switched off, the LED will be active for 10 seconds after reboot in its last colour scheme and then it will be switched off.

LED Reading (LGT)
The reading colour is Cyan, flashing

Input format: LGT 01111

Output: 01111

Reading mode is active for the duration of the TOR parameter. It will stop prematurely only to show a successful read using the respective colour. At the end of the TOR parameter, it will show the no-read mode LED colour.

LED Transponder number successfully read (LRD)
Successful read colour is green, no flash

Input format: LRD 01001

Output: 01001

Successful read mode is active for LRT seconds, after which the standby mode will be active again.

LED No Read (LNRD)
No Read colour is red, no flash

Input format: LNRD 10001

Output: 10001

No Read mode is active after TOR seconds for LRT seconds, after which the standby mode will be active again.

LED Return to standby (LRT)
Some modes require ARE i9 to go back to standby. The time until this happens is set by using the LRT command.

Input format: LRT time

Hex:| 4C| 52| 54| 20| 33| 30| 0D|  |
---|---|---|---|---|---|---|---|---|---
ASCII:| ‘L’| ‘R’| ‘T’| | ‘3’| ‘0’| |  |

Output: 30

LRT30 sets approx. 3 seconds as time for a return to standby (30x100ms)

LED Error (LERR)
The error color is red, flashing

Input format: LERR 10011

Output: 10011

Error mode is triggered by an error of ARE i9 and is active until a correct instruction is received.

LED Process active
In case of multiple commands being sent to the chip (e.g. rd and wd instructions), it may be necessary to control LED functionality manually. The LED Process active instruction sets the LED to a defined colour and mode. This colour and mode stay on as long as the LED Process active parameter is switched on. Normal LED functionality is discontinued during the activity of this parameter. LED functionality returns to normal only when the LED Process active is switched off via its X parameter.

Activating Process active
LED colour is yellow, flashing

Input format: LPA 11011

Output: 11011

Deactivating Process active
LED colour doesn’t care, because the parameter is switched off using the X parameter

Input format: LPA 11010

Output: 11010

LED Process status
LED Process status is used to indicate the status of a process after it is performed.

Successful Process
LED colour is green, not flashing

Input format: LPS 01001

Output: 01001

Not Successful Process
LED colour is red, not flashing

Input format: LPS 10001

Output: 10001

LPS stays on for LRT seconds and then returns to standby.

LED Setup help (FLED)

• To locate the respective ARE i2.0 HF hooked up to a particular RS 232 port, the instruction FLED is used.
• This instruction flashes the LED in white for 10 seconds. The colour can not be changed.

Input format: FLED

Output: FLED

After flashing for 10 seconds ARE i9 returns to standby mode.

LED (De)activate LED functionality (LED)
To deactivate (or activate) the LED functionality, LED instruction is used.

Input format: LED Parameter

Output: 0

• LED 0 deactivates LED functionality.
• LED 1 activates LED functionality (default).
• The above examples represent ARE i2.0 HF default values.

System Implementation

Power supply

• HF industry uses hdx LF RFID technology. This particular method relies on field gaps, where the RFID field is switched off. In this gap, the transponder answers with its code. This method has the advantage of a high read range in laboratory conditions. However, in an EMV-polluted environment, the read range of hdx transponders is significantly reduced as even low noise signals have a direct impact on read range.
• Therefore system integration must make sure that the power supply for ARE i2.0x HF is stable and clean with no noise. It is recommended to use linear power supplies rather than switching power supplies. All other applications benefit from this as well.

Grounding

• Please make sure that ARE i2.0x HF is properly grounded. This ensures proper functionality of the entire system comprising ARE i2.0x HF and AAN Xi9F. Please see Chapter 2.1.4 for details on grounding.
• Grounding can be achieved by grounding the DIN hat rail, as the clamp on the backside of ARE i2.0x HF is connected to the ground. Alternatively, the grounding pin on the front side of ARE i2.0x HF can be used to achieve this.

Mounting on metal

• ARE i2.0x HF typically mounted on a metal DIN hat rail in a metal electrical cabinet? There is no influence of metal on the performance of ARE i2.0x HF and therefore nothing to watch out for.
• It is recommended to mount AAN Xi9F HF onto a non-conductive surface. However, AAAN Xi9F HF is designed to work when mounted on metal as well. There is a slight decrease in read/write range when compared to mounting on non-conductive surfaces, but in most cases the read/write range will still be plenty for the application.

Frequency converters
Frequency converters used in electronic motors are a source of significant EMV noise. Make sure to stay away as far as possible from those frequency converters when designing spots where ARE i2.0x HF is to be used. Noise from frequency converters significantly reduces the read range of ARE i2.0x HF.
