1. General Information
1.1 Characteristics and Performance
H‘IPERXTM is a multi-tag dynamic identification system usmg microwaves. A ‘reader’ emits
microwaves up to a distance of one or more meters, depending on model When a tag enters this
zone. it modulates this radiation, thereby sending its code back to the reader. which then processes
the received signal and extracts the code.
The readers LML_3013 . LML_3033 and LVM_4033 are modular readers comprising of electronic
modules assembled within a chassis The antenna is external to the chassis. connected with two
coaxial cables The principal characteristics are :
- Hands-free Reader LML_3013, range 2 m (7 feet) and passing speeds up to 20 Kmlh (15 mph),
- Hands-free Reader LML_3033, range 8 m (25 feet) and passing speeds up to 20 Kth (15 mph).
- Hands-free Reader LVM_4033, range 5 m (16 feet) and passing speeds up to 100 Km/h (60 mph).
- Range adjustment by potentiometer
- Directive Microwave beam :
0 Virtually insensitive to environmental interference
0 Can be pointed to illuminate a particular area
0 installation on metallic surface with no performance reduction
- Simultaneous identification of5 tags in 1 second
0 Several tags can be present in identification zone. intentionally or not
- Identification in nearly all tag positions:
0 Back I Front
0 Horizontal/Vertical.
- Coexistence of 31 readers in same zone
0 access with successive access
0 acess points close together
0 Precautions
0 Human bodies and metallic objects between tag and antenna can obstruct identification
0 Close contact (<5 mm) between tag and body or with metallic surface can reduce reading
range

For the readers LML_3013, LML_3033 and LVM_4033, this cable must be equipped with a ferrite
bead. located on the cable portion inside the enclosure (ref Steward : 2882029-0A0 or equivalent)
1.5.3 Line Termination
For a simplex |Ink, the termination (if present) should be placed at the receiving end of the line.
For a duplex link, the termination (if present) should be placed at the each end of the line,
For baud rates less than 1200 bauds, no termination is necessary. For baud rates greater than 9600
bauds and line lengths greater than 1000 metres, a resistor equal to the line impedance (120 ohms) is
usually necessary. For cases ln-between, there is no clear-cut rule and depends on individual
installations (combination of baud-rate. line-length, cable quality, emitter/receiver characteristics).
1.5.4 Electrical connections
For an RS«232 link, wiring up is straightforward, the TX and RX lines of both equipments are
connected together.
For a differential link (RS-422 or RS4BS), the polarities are not always clearly defined. Normally the
“Ir" line is at a high level at rest and is active low, For the “—" line. the opposite is true, This is the case
for the differential interface for the HYPERX readers However if the differential signals are generated
by a converter acting on RS-232 signals. then the “+" line can be at a low level at rest and active high.
In this case, the “+“ line of one equipment must be connected to the “-‘ line of the other equipment.
Connection at 0V
Whether this is necessary or not, depends on the installation. lf host and reader are distant with
different local ground potentials, then an RS-232 link may not work if the CV references are not
connected. However connecting them will cause ground currents to circulate. In general, for large link
lengths, a differential link should be used This also tolerates a large common-mode voltage
difference,

2.1.5 Antenna AT1 (LML_3013)
The antenna AT1 has a two—coloured lamp in the upper right corner. When the reader box is closed,
this is the only visible signal that the user perceives. The lamp is under reader-software control, either
in automatic mode or controlled by the host via the serial link.
Normal operation is a slow blink (0 5 s on, 0.5 5 off) with the lamp remaining ofl for 1 second when a
tag is first detected.
The state diagram below shows the different possible states during power-up (or after a processor
rest) and their meaning.

Notes :
1. The LED behavrour and the timeout duration depend on the nature of the fault. In the case of a
faulty configuration, the reset is immediate and the LED stays red. For a hardware fault, reset takes
place after 4 seconds.
rid = not defined
x = don't care
This state only exists for the modular readers.
51115?!“
This state is not shown in order not too overload the diagram. it lasts for 1 second. then normal
operation resumes
2.2 Buzzer
The buzzer is located on the SPI module and is under reader software control. It sounds at power-up
and on processor reset (for about 2 seconds).
When enabled, the buzzer emits a short sound (duration 50 ms) each time a tag is read. Thus, for a
tag that remains in the reading area, the buzzer will sound continuously. This is independent of issuer-
code filtering (see §3.6).
Buzzing on tag detection can be disabled by user switches (see §3.5).
2.3 Reset button
The reset button is on the front panel of the SFl module. Pushing it causes a processor reset (the
button does not need to be held in) which lasts about 2 seconds. During this time, both 'CPU' and
BURST lamps light up. Upon reset. any user settings loaded by the host via the serial link are lost.

3.3 Message mode
The mode is chosen using positions 1 and 2 on JJ , The mode determines in what cases the detection
of a tag causes a message to be transmitted to the host.
Type 0 , Each time a tag is detected, a timer Is armed (nominal value = 15) Tag detection only
causes a message to be transmitted if this timer is not active. Each tag detected has a
timer associated with it.
Type 1 - This mode ls no longer supported
Type 2- At each tag detection. a message is transmitted to host. During message transmission,
microwave emission is switched oflE Oniy availabie for the 1502 interface and the
asynchronous start/stop interface in the interrupt mode
Type 3- When a tag “disappears" (is removed from internal memory). an extra message is
transmitted to host which includes the tag‘s code as wait as the number of times that the
badge was detected. This number cannot be greater than 99. Not avaiiable for the
Vihegand interface. Otherwise identicai to type 0.

The reader can operate using 31 different channeis. Each channel corresponds to a separate
microwave frequency band, This is useful when several readers must be positioned close together.
Using different channeis on each reader eliminates mutual interference. The SHF module has 6 small
switches on the lront panel aliowing a selection of 31 different channels (switch 6 is not used and 2
channels - 0 and 9 - are identical and use the same frequency)

5. Annexe B : Special Modes (Test Mode And Minitel Model
Test Mode
This mode is configured using switch 8 of J3 (see 324)
The |nformation transmitted from the reader to the host normally uses a JBUS frame format“ During
system installation, the host computer may not yet be connected or available For this reason , an ASCII
transmission mode exists, allowing the connection of a dumb terminal in order to visualise the messages
sent and thus to verify correct system operation. This is called test mode and is enabled using a board
jumper configuration
This mode has the following characteristics ‘
o interrupt mode is used (the tag-code is sent immediately)
- tag persistence = 1 second
- frame structure = 24H / status tag I 20H / code / ODH / OAH
- transmission characteristics (baud rate and character format) must be configured
Exaine:
During system installation, the reader is put into test mode. A terminal is connected to the reader via an
RS-232 linki Transmission characteristics of reader and terminal are matched, and tags are held in front of
antenna The terminal will display messages of the type:
$0 001AECDEF-100
$2 XYZHYPER X.007
The messages have the foliowrng structure .
$ (space}  
where status badge : O = antenna 1, tag battery good
i = antenna 1. tag battery low
2 = antenna 2, tag battery good
3 = antenna 2, tag battery low
distributor code: nnn where n is a digit (0 a 9)
user code : lrom 1 to 30 characters

Mode Minitel
This mode ls configured using switches i to 4 of J4 (see §3.2.1)
This mode is similar to test mode, in that the messages sent have the same format (see above), yet it
takes the specific nature of minitel operation into account. On a reader reset, special codes are sent which
- clear the screen
0 position the cursor in the upper left corner
- configure the minitel in scroll mode
Additionally, transmission characteristics are fixed independently of switches 5 to 8 of J4 : 1200 baud‘ 7
. bits data, even parity, Only switches 1 to 4 of J4 need to be set.
This is a simplex link, reader to minitel, and needs switch 2 of J1 to be ON.

1 . GENERAL INFORMATION
1.1. Description of the HYPERX readers
HYPERX‘“ is a multi-tag dynamic identification system using microwaves. A ‘reader‘ emits microwaves up to a
distance of one or more meters. depending on model. When a tag enters this zone, it modulates this radiation,
thereby sending its code back to the reader, which then processes the received signal and extracts the code.
There are two types of readers. modular (different modules assembled in a rack) and compact. For the modular
readers, SPI is the reader module which provides the host interface. SPI performs digital processing of the
signal received from the microwave receiver module (SAM or LAM) and communication functions with a host.
It plugs into a custom rack for single-Europe size boards. taking up a slot of width SE. A custom backplane
provides interconnection between the modules. The compact reader is a compact version of the basic modular
reader in the form of a single box. It performs basically the same functions as the modular reader, with
differences in performance (see the appropriate product specifications).
Basic functions performed are :
- tag detection
- relay 24V/1A for external circuit-switching (controlled via host).
- communication interfaces:
- asynchronous serial link (RS 232. RS 422 or R8 485) using JBUS’M / MODBUSW' protocol (polled or
interrupt)
or
- compatible magnetic stripe card format "180-7811/2"
or
- compatible WIEGAND tags
Certain functions described in this document are only relevant to recent firmware versions, Identify the version
you are equipped with and make sure the desired function is supported.
1.2. Basic operation
Tags are encoded with a HYPEFtX‘M programming device. They can contain a user code of up to 30 characters
(digits, uppercase letters and some punctuation symbols) They also contain a 3-character distributor code.
When a tag is first detected. it is stored in an internal buffer and remains present for a time Tr. After this time,
the tag is removed from memory, At first detection, a message for the host interface is generated and the relay
is activated. In most cases (ISOZ. Wiegand, asynch link interrupt mode) this message is immediately sent. in
one case (asynch link polling mode) the message isonly sent on request by the host. If a tag is detected by the
reader and it is still in memory (two detections of same tag within the time Tr). a new message is not normally
generated (exception is message mode 2. see chapter 3.3). The timer associated with this tag is then reset so
that the tag remains present for a further time Tr. Thus, for a tag which is presented to the reader and remains
there, only one message is generated after the initial detection. The tag must be removed for a time greater
than Tr in order for a second message to be generated.
In the case of an asynchronous link to the host. the default value for Tr is 1 second, however this value can be
changed via a JBUS command. In the case of an [$02 or Wiegand interface. the value is determined by board
iumper settings. The time Tr is hereafter referred to as the tag persistence time.

Once a second. the status ol the reader is monitored. This information is available to a host connected by a
serial JBUS link. It also affects the flashing rate 0! the CPU led on the front panel and the colour and tlashing
rate of the antenna indicator lamp (see chapter 23).
In the case at the modular reader, an SPl module can accommodate up to two receivers, each with its own
antenna. In this case, all modules making up the two receivers are present in the same wide bay. This is known
as a Double Fleader. When a tag is detected, status information in the message to the host indicates at which
antenna the tag was detected. This inlormation is only available it an asynchronous serial link connects the
readerto the host.
For the Double Reader. in some cases signal teed-through on the antenna cables can cause a tag detected by
one antenna to be “seen" by both receivers. This produces two detection messages, one corresponding to each
antenna. in order to counter this effect, it it occurs, a special switching mode of operation can be used whereby
only one of the two receivers is active at a time. switching taking place every 150ms. This means however that
during the 150ms. one oi the antennas will not detect tags that may be present and this may reduce its reading
efficiency, especially for high-speed or multi-tag applications.
1.3. Power Supply
The acceptable input voltage range for both types of readers is 10VDC to 25VDC. The compact reader
consumption is roughly 250 mA at 12 VDC. The consumption tor modular readers depends on their
composition
WARNING : Live insertion or withdrawal of the SPl module can cause irreversible damage !

2. OVERVIEW
2.1 , Connectors
There are several PHOENIX - type connectors:
. The S-pin connector is for the serial link to a host.
- The 3—pin connector allows switching (using the internal relay) of an external circuit
- Forthe compact reader only, a 2-pin conneclor is for the DC power supply
(See chapter 7 for the wiring instructions)
For the modular reader, the connectors are accessible on the lront panel of the SPI module. For the compact
reader, the connectors are éccessible from the back at the top.

3. CONFIGURING THE MODULAR READER
There are two versions of the module currently available, for simplicity hereafter referred to as the old version
and the new version. The old version consists of a mother board and a smaller daughter board using traditional
through-hole technology. Configuring is done using jumpers. The new version consists of a single board using
surface-mount technology, Oonliguring is done using miniature switches. In order to correctly configure the
module, you must identify the version you are installing. In lhe following paragraphs, text in [mics refers to the
old version.
For old versions only - some jumpers do not change position :
J1 - must be in position 2-3
J6 - must be present
J7 - must be absent ‘
J13 - must be present in position 2-3
These four jumpers no longer exist on the new version.
The different operating modes are selected using switches/jumpers which are either :
- ON (present) or
- OFF (absent)
They are identified by their positions on four connectors:
c Jt (8 positions 1 to 8)/J3 (toposiiions 1 to 10)
. J2 (4 positions 9 to 12) /JB (2 positions 17 to 12)
- J4 (a positionst to 5) /J4 (5 positions 1 to 8)
- J3 (8 positions 1 to 8) /J5 (Eposrtions 9 to 16)

5.1.2. Message format
A message consists of a preamble of 15 zeros (for receiver synchronisation), the data frame as described
below, and a postamble of 10 zeros.The data (digits 0 to 9 only) are formatted into characters of 5 bits - 4 bits
fora BOD coding plus one bit for odd parity. The data is framed as shown below.
1 Character 1 Character 1 character

START character = OBH
END character = tFH.
The contents of the data field depend upon the message mode chosen and the length. For a variable length
frame, this field begins with a three-character distributor code, if no distributor-code filtering is enabled,
followed by the usercode. For the fixed length frame, this field contains exactly 37 characters, the characters
after the user-code, ifthere are less than 37, are all equal to ODH.
In the case of message mode 3, the data also contains the number of times the tag was detected, a two-
character field. The special separation character OOH precedes this number.
The order of bit transmission for each character is LSB lirst.
Typical examples of the data field for a user code of length 11 digits :
message mode 0. length variable
distributor code user code length = 3 + n
message mode 3, length variable
d butor code user code -mm length = 3 + n + 3
message mode 3, length variable, distributorcode filtering

5.1 .3. Tag persistence
The tag persistence (the time that a tag is stored in internal memory) can be set to one of four values using the
board configuration (see 3.1.3) : 1 s, 2 s, 5 s and 10 seconds.
5.1 A. Tag code transmission

5.2. Wiegand compatible interface
5.2.1, Description
Using this intertace allows the reader to take the place of a Wiegand-effect card reader. This interface
comprises two signals, DATA “0" and DATA “1". A logical 0 produces a negative pulse on the DATA_O line
and a logical one produces a negative pulse on the DATA_1 line. The timing is given in figure 5 below. The
data is transmitted synchronously in a frame format at a rate of roughly 2000 bits/s

5.2.3, Distributor code auto-learn mode
This facility is automatically enabled if the Wiegand interface is selected. However, it can also be enabled for
the other interfaces if desired.
As well as the user data field, which for Wiegand corresponds to the 26 bit frame described above, the
HYPEHX tag contains a three character distributor code which is unique for each installation. This code is
automatically added when the tag is first programmed.
The distributor code contained in the first tag which is detected after a processor reset becomes the reference
distributor code. it is memorized, and the distributor codes of all succeeding tags are compared to this
reference. If they are the same, the tag is allowed, if not the tag is rejected. In the former case, the message
transmitted to the host does not contain this distributor code.
The distributorcode consists of three ASCII digits, 0 - 9, allowing 1 000 combinations.
5.2.4, Tag persistence
The tag persistence (the time that a tag is stored in internal memory) can be set to one of four values using the
board configuration (see 3.1.3) 1 s, 2 s, 5 s and 10 seconds.

6. COMMUNICATION PROTOCOL FOR ASYNCHRONOUS INTERFACE
61. Introduction
Readers can be connected to a host using either a point-to-point configuration or a multipoint (bus)
configuration. Furthermore, two types of protocol are possible : polling by host or interrupt.
The interrupt protocol uses either the JBUSW frame format or the test mode format,
NB :
(1) The interrupt protocol can only be used on a point to point link.
(2) JBUSTM is registered by APRIL . MODBUSWI is registered by GOULD MODICON
A multipoint or network configuration using the standards for differential data transmission HS-485 (2-wire, 2-
way) or R57422 (4-wire, 2 for each way), is used it several readers are to be interconnected In this case the
polled JBUS protocol is implemented
(fl
HOST

it only one reader is to be connected. either of the three standards can be used. In this case either of the two
protocols, polled (see chapter 6.3) or interrupt (see chapter 5.5). are possible.

6.2. Transmission characteristics
All protocols are character-oriented. The character formats are :
o 7 bits even parity/ 1 stop bit
. 7 bits odd parity /1 stop bit
- 6 hits no parity /1 stop bit
Four baud-rates are possible :
1 200 bauds
0 4 800 bauds
- 9 600 bauds.
o 19 200 bauds
Choices are configured by user (see chapter 3.2.2).
NB : In practice, the JBUS protocol requires 8 bits / no parity. The other formats are used for special situations.
63. Reader in Polled Mode
This is a master/slave protocol. Each exchange is initiated by the master and consists, except in one case
(broadcast message), an exchange of two frames - a command issued by the master and a reply from the
slave. All frames have the following structure :
Slave no. function code| data l control
NB : A HVPEFl X reader is a JBUSTM slave.
The commands issued by the master are either addressed to one slave (identified by its number or address) or
to all slaves on the network (broadcast).
The four fields have the following meanings :
- Slave number (1 byte) :
Specifies the destination, from 1 to 12. It the number is 0, it is a broadcast message. In this case there is no
reply,
o function code (1 byte) .
Command : Determines the type of action to be performed (read, write, bit, word).
Reply : Result (success or error),
- data field (n bytes):
Contains the parameters associated with the function : command code, number of bytes, values.

- control field (2 bytes):
For error detection (CFlC 16) - See chapter 12.
The JBUSWI protocol defines 12 functions (second field in frame). The following tour of them are implemented
on the HYPEth readers:
- function 3 : read n words
- function 5 : write one bit
a function 6 : write one word
- function 16 : write n words
The main difference between the reader‘s reply and the host‘s command is the content of the data field,
lf the message is received with errors (CRC incorrect), the reader does not reply. It the message is received
correctly but the reader cannot process it, an error message is sent. This error message has its function oode
field modified, (the msb is set to 1) and the data field contains one byte, an error code with the following
values :
Error code
S stem non read
Execution failure
Example :
PC 7> reader 01 03 00 39 00 01 54 07 (incorrect command)
reader —> PC 01 B3 02 00 F1
The maximum time allowable between the reception of two characters is a protocol parameter which allows a
slave to resynchronise to a lrame-start, if transmission is interrupted. if this time is exceeded, the slave rejects
the frame currently being received, For the HYPERX reader. this time is equal to 20 ms except in the case of a
baud-rate of 1200 bauds for which it is 30 ms

(f) Command 13 is only available (or the compact reader
(1) Command 4 is onlyavailable for the modular reader
ln order to read a tag (in polled mode), the host must first issue the command get reader status The status
word informs the host it a tag has been read, and if so, the length of the tag-code in bytes (see 6.43 below), In
the latter case, the host then issues a second command get tag, indicating the number at words to be read.
NB : In interrupt mode, the command get tag is not used, since all tag-codes are sent immediately.
The words status_l, status7m, status), led, emis, time, version, channel and config are 16 bit words
arranged as two bytes, msb first, lsb last.
604.1. Get reader status
This is a command of type read n words. code = 0040H. It the command parameter nb words is not equal to
1, the reader replies with the JBUS error 3 (Data incurred).
The reader returns one word statusJ (two bytes, MSby‘te first),

64.9. Ftetransmit previous tag
This is a command of type read n words, code : 0046H, If the number at words to be read (chapter 64.1) is
different trorn the number of words available the reader replies with the JEUS error 8 (execution failure). This
error is also produced if no tags are present.
This command makes the reader retransmit the previous tag code, providing no other transmission has
occurred since. It is used in polling mode it the reader's reply contains errors and the host wishes a
retransmission. In such a case, repeating the command read tag is of no use, this command must be used.
The number at words to be read must be the same as that used in the previous read tag command.
Example :
PC —> reader 01 03 00 42 00 03 AS OF (read 3 words)
reader —> PC 01 03 06 01 02 03 04 05 16 SB BS (CFiC incorrect)

6.4.10. Get lnit Errors
This is a command of type read n words. code = 004FH. If the command parameter nb words is not equal to
1, the reader replies with the JEUS error 3 (Data incorrect)
The reader returns one word statuswe (two bytes, MSbyte first).
After a manual reset, the reader performs an internal test of its major hardware elements. If an error is
detected. the MS bit in the reader status word is set (see 6.4.1) and the reader resets itself after 4 seconds and
continues to do so until the fault disappears, This command, it sent after the end of the test (the buzzer sounds
while the test is in progress), will determine the nature of the fault. One word status_e is to be read:
Only the 5 bits D0 to D4 are used :
status_e
D15 D8D7 DO
|x|x|x x x xlxlxlx x xlscclsce SCA RAM ROM
ROM : EPFlOM checksum is incorrect
RAM :RAM failure
SCA :SCC channel A failure

SCC : SCC bus access failure
The bits are active at 1.
Example :
PC —> reader 01 03 00 4F 00 01 BS DD
reader —> PC 01 03 02 00 00 BE 44 (no errors)
6.4.11. Get EPROM version
This is a command of type read n words, code = 0049H, if the command parameter nb words is not equal to

The reader returns one word version (two bytes, MSbyte first).
version

DIS om rm 012 on 010 D9 Delmlcsloslm D3 oz m col
For the modular reader, the identifier has a fixed value equal to 0. For the compact reader, this value is equal
to 5,
Thus, version = 0401 H indicates a modular reader with EPROM version 4.01.
Version = 5403H indicates a compact reader with EPROM version 4.03.

6.5. Reader in interrupt Mode
In this mode, as soon as a reader has a message to send to the host (Le. a tag that has been detected), it
sends it, rather than waiting for an invitation, as is the case in the polled mode. The host replies with an ACK or
a NAK. The message sent has the following structure:
1 byte nbms
STX L— 04| nbcharacters values |CH016 J
This structure is the same as that of a ‘reply’ frame to the command read it words. The first field, the reader
number, is fixed at 2 and the second field, the code function, is fixed at 4.
Example :
11 bfles
| ozl 04] DB 3041424333343536373839| onc1s|
Here, the badge status = ‘0‘, the code read is ‘A803456789'
The data field contains 11 bytes.
See chapter 6.4.3 for details of the structure of the data field.
The same message is retransmitted up to three times in case an ACK is not received. If a NAK is received the
message is sent again immediately, it no reply is received the message is sent after a 100ms timeout. After
three tailed attempts, transmission for that message is abandoned.
This protocol is enabled using reader configuration (See chapter 3.2.3.)
NB :
In this mode of operation, the host can send all of the normal commands using the JBUS protocol (as defined
in chapter 6.4 above), except for the one command read tag which would make no sense. The reader sends a
reply just as if it were in polled mode However, the reader cannot send a reply straight away if it has just
detected a tag and has started to send this message, and vice versa. The host must decide if and when it can
safely interrogate the reader.

For baud rates less than 1200 bauds. no termination is necessary. For baud rates greater than 9600 bauds and
line lengths greater than 1000 metres, a resistor equal to the line impedance (120 ohms) is usually necessary.
For cases in-between, there is no clear-cut rule and depends on individual installations (combination of baud-
rate, line-length. cable quality, emitter/receiver characteristics).
7.3.4. Electrical connections
For an FlS-232 link , wiring up is straightforward, the TX and RX lines of both equipments are connected
together.
For a differential link (RS-422 or RS-ABS), lhe polarities are not always clearly defined. Normally the “+" line is
at a high level at rest and is active low. For the line, the opposite is true. Ihis is the case for the differential
interface for the HYPERX readers. However if the differential signals are generated by a converter acting on
RS-232 signals, then the "+" line can be at a low level at rest and active high. In this case, the “+‘ line of one
equipment must be connected to the “-" line of the other equipment.
Connection of UV
Whether this is necessary or not, depends on the installation. If host and reader are distant with different local
ground potentials, then an HS-232 link may not work if the CV references are not connected. However
connecting them will cause ground currents to circulate. In general, for large link lengths, a differential link
should be used. This also tolerates a large common-mode voltage difference.
7.3.5. Networking

11. APPENDIX D : DESCRIPTION OF TEST MODE
The information transmitted from the reader to the host normally uses a JBUS frame lonnat.. During system
installation, the host computer may not yet be connected or available. For this reason , an ASCII transmission
mode exists. allowing the connection of a dumb terminal in order to visualize the messages sent and thus to
verify correct system operation. This is called test mode and is enabled using a board iumper configuration
This mode has the following characteristics :
- interrupt mode is used (the tag-code is sent immediately )
~ tag persistence = 1 second
- frame structure = 24H / status tag I 20H / code / ODH IOAH
0 transmission characteristics (baud rate and character format) must be configured
Example
During system installation, the reader is put into test mode. A terminal is connected to the reader via an RS-
232 link. Transmission characteristics of reader and terminal are matched, and tags are held in front of
antenna. The terminal will display messages of the type :
$0 OO1ABCDEF-100
$2 XYZHYPER X.0l)7
The messages have the following structure :
$ (space)  
where status badge : 0 = antenna 1, tag battery good
1 = antenna 1, tag battery low
2 = antenna 2, tag battery good
3 = antenna 2, tag battery low
distributor code : nnn where n is a digit (0 a 9)
user code : from 1 to 30 characters. see chapter 6.4.3.
