Introduction
ARE i2.0x SEMI is a compact industrial reader based on an RS-232 interface.
This version is compatible with SEMI
applications. ARE i2.0x SEMI uses an external antenna for communication to the
transponder. There are various antenna form factors available.
Typical system structure
Manual ARE i2.0x SEMI release V2.docx
ARE i2.0x SEMI
ARE i2.0x SEMI works with LF hdx transponders that comply to SEMI standard 144-0312.
2.1 ARE i2.0x SEMI hardware
2.1.1 Dimensions ARE i2.0x SEMI
2.1.2 Protection Class
Protection Class is IP 67, assuming cable or dummy cap is mounted.
2.1.3 AAN Xi9F dimensions
2.1.4 Mounting and grounding
Mounting is recommended via the top hat rail connector on the back of the
unit.
Note: Grounding of the unit can be achieved by grounding the top hat rail. The
top hat rail connector is hooked up to
internal system ground. Alternatively mounting straps are optionally
available.
2.1.5 Connectivity:
ARE i2.0x SEMI is connected via its M12, 5-Pin male A-coded plug. Power supply
as well as communication is provided by user. Do only use specified cables.
ARE i2.0x SEMI uses a LED lit RFID symbol on its front side to visually
communicate its various states (standby, reading, successful read, no read,
error, and so on…). When ARE i2.0x SEMI is hooked up to power, the internal
LED is switched to standby color. LED colors can be set by the user.
The antenna AAN Xi9F is connected via a 3-pin connector on top of ARE i2.0x SEMI.
ARE i2.0x SEMI uses an external antenna AAN Xi9F. There are air core coil
transponders like disks and ferrite core coil transponders like glass tube
transponders. It is important to understand the impact of orientation of
transponders relative to AAN Xi9F. Optimum orientation is parallel to the top
side of the antenna for glass tube transponders. In this orientation, the
highest read range can be achieved.
If it is not possible to ensure such orientation, glass tube transponders can
be oriented perpendicular on the outside of the antenna. This will result in
some decrease of read range, but in most cases this is acceptable.
Reading distance depends a lot on the particular installation. Absolute values
only make sense based on a particular
transponder. Absolute values make no sense for transponder types, because the
values will vary too much. Above are the guiding principles to achieve the
best possible read range.
2.1.6 Read Range for SEMI Applications using AAN Xi9F
Glass transponder acc. to SEMI E144-0312 standard
Glass transponder parallel (recommended)
The highest read range is achieved right above the center of AAN Xi9F front side.
Glass transponder 90° perpendicular
The highest read range is achieved right at the perimeter of the antenna
housing.
*note: only one transponder in the field at a time. Above illustration only shows possible read ranges.
2.2 Firmware ARE i2.0x SEMI
2.2.1 Instruction Set
Communication with ARE i2.0x SEMI is based on a simple ASCII text based protocol. The host sends text based telegrams to ARE i2.0x SEMI and receives text based telegrams back containing the answer to the query. Communication to ARE i2.0x SEMI is always triggered by the host.
2.2.2 General format of instruction set
The protocol format is as follows
2.2.3 BD
BD – Baudrate parameter sets the baudrate for ARE i2.0x. Please Note: Standard parameter is 38.400 baud.
2.2.4 VER
VER – Reader firmware version
VER is used to get the actual reader firmware version.
2.2.5 TOR
TOR – Timeout Reading
After a read is triggered by GT, TOR is a time during which ARE i2.0x SEMI
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 (XXXXXXXXXXXXXXXX) is sent to the host
after TOR time has expired.
The chosen parameter for TOR is sent as acknowledgement.
A TOR value of 50 equals 50 x 100ms = 5000ms = 5 sec.
It is recommended to set TOR value to the amount of time it takes in a dynamic
situation for the transponder to travel over ARE i2.0x SEMI. This maximizes
the number of possible reads, in order to compensate for EMV noise in the
vicinity.
2.2.6 GT
GT – Get Tag
GT is used to retrieve the transponder UID. GT uses TOR parameter to define
the time during which the reader continuously looks for a transponder without
the need for the host to get involved.
In SEMI application this command can be used to retrieve the carrier ID stored
in memory block 1 of SEMI compatible transponder.
2.2.7 RD
RD – Read transponder memory page
RD is used to read an individual memory page from a transponder in the field.
RD uses TOR parameter during which the reader continuously looks for a
transponder without the need for the host to get involved.
Please see datasheet of transponder for specific memory map. Page is input as
decimal.
2.2.8 WD
WD – Write transponder memory page
WD is used to write to individual memory page of a transponder in the field.
WD uses TOR parameter during which the reader continuously looks for a
transponder without the need for the host to get involved.
Please see datasheet of transponder for specific memory map. Page is input as
decimal.
2.2.9 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
mode is switched back to single read
2.2.10 NID
NID – Double reading of UID to ensure consistency in EMV polluted environment.
NID is used to double read a transponder UID to ensure consistency in an EMV polluted environment. The transponder UID is transmitted only after two consecutive reads of the same UID
2.2.11 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
interface. There needs to be one different Transponder UID read before the
same number will be transmitted again.
2.2.12 CN
CN – Filter no read from being transmitted via interface.
CN is used in those cases, where no read information ‘XXXXXXXXXXXXXXXX’ is not
to appear on the interface. Only valid transponder UID will be transmitted.
2.2.13 LD
LD – lock memory page
LD is used to lock a particular memory page from a transponder in the field.
If there is an error during locking, the answer will be XXXXXXXXXXXXXXXX
2.2.14 VSAVE
VSAVE – Save parameter permanently in ARE i2.0 SEMI flash memory
VSAVE is used to save parameters permanently in flash memory of ARE i2.0 SEMI
to be available after power on.
2.2.15 INIT
INIT – Restore standard parameters. Command needs to be followed up by VSAVE
in order to permanently store the parameters.
Input format: INIT
2.2.16 Error messages
Error messages and protocol errors are acknowledged by ARE i2.0x SEMI using an
error code. The format is described below:
2.3 LED instruction set
ARE i2.0 SEMI employs a multi-color LED to signal different modes.
Basically below colors can be created:
The user can choose any color apart from white. This color is reserved for
setup help functionality as described below.
The following modes use a distinct color 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:
Mode
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 colors are shown with the instructions.
2.3.1 LED Standby (LSTB)
Standby color is Cyan, no flash.
Standby mode is active if no other instructions are carried out.
If Standby LED is switched off, the LED will be active for 10 seconds after
reboot in its last color scheme and then it will be switched off.
2.3.2 LED Reading (LGT)
Reading color is Cyan, flashing
Reading mode is active for the duration of the TOR parameter. It will stop prematurely only to show a successful read using the respective color. At the end of the TOR parameter it will show the no read mode LED color.
2.3.3 LED Transponder number successfully read (LRD)
Successful read color is green, no flash
Successful read mode is active for LRT seconds, after which the standby mode will be active again.
2.3.4 LED No Read (LNRD)
No Read color is red, no flash
No Read mode is active after TOR seconds for LRT seconds, after which the standby mode will be active again.
2.3.5 LED Return to standby (LRT)
Some modes require ARE i2.0x SEMI to go back to standby. The time until this
happens is set by using the LRT command.
LRT
2.3.6 LED Error (LERR)
Error color is red, flashing
Error mode is triggered by an error of ARE i2.0x SEMI and is active until a correct instruction is received.
2.3.7 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 color and mode. This
color and mode stays 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 LED Process
active is switched off via its X parameter.
Activating Process active
LED color is yellow, flashing
Deactivating Process active
LED color doesn’t care, because parameter is switched off using X parameter
2.3.8 LED Process status
LED Process status is used to indicate the status of a process, after it is
performed.
Successful Process
LED color is green, not flashing
Not Successful Process
LED color is red, not flashing
LPS stays on for LRT seconds and then returns to standby.
2.3.9 LED Setup help (FLED)
In order to locate the respective ARE i2.0 SEMI hooked up to a particular RS
232 port, the instruction FLED is used.
This instruction flashes the LED in white for 10 seconds. The color can not be
changed.
After flashing for 10 seconds ARE i2.0x SEMI returns to standby mode.
2.3.10 LED (De)activate LED functionality (LED)
In order to deactivate (or activate) the LED functionality, LED instruction is
used.

System implementation
3.1 Power supply
SEMI 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 high read range in laboratory
conditions. However, in a EMV polluted environment, read range of hdx
transponders is significantly reduced as even low noise signals have a direct
impact on read range.
Therefore it is absolutely mandatory for system integration to make sure that
power supply for ARE i2.0x SEMI is absolutely 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.
3.2 Grounding
Please make absolutely sure that ARE i2.0x SEMI is properly grounded. This
ensures proper functionality of the entire system comprising of ARE i2.0x SEMI
and AAN Xi9F. Please see chapter 2.1.4 for details on grounding.
Grounding can be achieved by grounding DIN hat rail, as clamp on backside of
ARE i2.0x SEMI is connected to ground.
Alternatively, the grounding pin on the frontside of ARE i2.0x SEMI can be
used to achieve this.
3.3 Mounting on metal
ARE i2.0x SEMI is typically mounted on a metal DIN hat rail in a metal
electrical cabinet. There is no influence of metal on performance of ARE i2.0x
SEMI and therefore nothing to watch out for.
It is recommended to mount AAN Xi9F onto a non-conductive surface. However,
AAAN Xi9F 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.
3.4 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 SEMI to be used. Noise from
frequency converters significantly reduce read range of ARE i2.0x SEMI.
