8 Introduction
MICHOSCAN is an easy to use transponder read/write device. The TIFIIS version reads all TIRIS
transponders and writes data into all r/w TIFiIS transponders. Since MICHOSCAN is driven by a
simple ASCII protocol it is easy to integrate the device into any existing or new application.
Please refer to our Internet Web Site at MIME I0! latest information on our products.
Before using the MICROSCAN,
read this manual oareIulnyrom the beginning.
It contains important inlormationl
Getting started
7 Getting Started
In order to prepare the MICROSCAN tor the first use carry out all of the following steps:
1. unpack all components
2. switch on your personal computer (PC). connect the MICHOSCAN to the serial interface of the
PC using the FtS-232 interface cable and switch on the PC
3. plug In the mains adapter and connect it to the MICROSCAN. Observe mains voltage!
4. start working with your MICROSCAN
7.1 Quick Start
Stan aterminal program on your PC (Telix, Procomm, Hyperterm, or similar).
Choose the serial interface to which you connected the MICROSCAN. Set the parameters as follows:
9600 baud
1 start bit
B data hits
no parity
1 stop bit
Start a reading cycle on the MICHOSCAN using the [STAH'H key. MICROSCAN tries to read a
transponder within a certain time frame. it a transponder has been read successfully, its data will be
sent to the PC and the reading cycle will stop.
8 When MICROSCAN "hangs”
In certain situation, e.g. when there is a configuration error. the pocket MICROSCAN may stop its
work. There are two ways or resetting the system:
8.1 Disconnect supply voltage
Simply disconnect the system from the supply voltage and wait for 30 seconds. Connect the
MICHSCAN to the supply voltage again.
The system will reset itself and will be operational Immediately. Parameters previously set through
serial commands will not get lost.
8.2 Send RESET command
It the MICHOSCAN produces abnormal results this may have been caused by wrong parameter
combinations. You may reset the default parameters anytime with the RESET command (see 10.2.9)
through the serial interface.

10.1 Introduction
Software
MICROSCAN is equipped with a powerful interpreter that is controlled by serial ASCII commands.
Ail commands have to be sent With trailing CFl LF (0x00, OXOA) characters. MICROSCAN answers
with trailing CH LF as Well.
it a command contains values between 0 and 255, these parameters have to be sent in hexadecimal
lorrnat with a leading \ and a trailing \ character. For example, if you want to transfer a horizontal TAB
(0x09), you should send \09\ to the MICROSCAN.
MCROSCAN will answer in one of these ways:
[ACK] (0x06)
Acknowledge; the command was successful
Ignore; the command was invalid
Error; there was an error in the command

1.2
General
The Micro-reader is an intelligent module providing RF and Control functions to read
and program TIRIS transponders. it is equipped with a Serial Communications Inter-
face (SCI) which may be directly connected to commonly used system controllers.
The Micro-reader works together with e 47 pHenry, low-Q antenna, and therefore the
system does not need tuning.
Figure 1: Micro—reader Module
lili
Product Description
The Micro-reader module is a plug-in module which can be plugged into or soldered
onto an application specific adapter board. it supports serial data communications
between a PC and TlRIS transponders. With its Serial Communications Interface
(SCI) the Micro-reader supports TTL data communications. which with the addition
of a communications driver (for example: R3282 or RSAZZ) allows communication to
a standard interface.
The Micro-reader can be controlled remotely by either providing certain inputs with
the corresponding voltage level or sending commands to the SCI. It can be driven
either with or without synchronization - the synchronization can be either wireless or
wired to enable reliable operation in multi—reader environments. Two outputs show
the reader status and inform the user about a successful command execution. The
Micro-reader supports all available TIRIS LF transponders.
May ‘00 Chapter 1. Product Description
1.2.1 Power Supply
There are two separate 5V supplies to the Micro»reader, one for the output stage
(VSP) and the other forthe logic (VSL). On power up VSL should rise faster than 0.1
Vlms to ensure a reliable operation. The Micro-reader has an on-boerd reset circuit
which will reset it should the supply fall below 4 V (i 0.2 V).
In orderto avoid problems with noise conducted via the supply lines, we recommend
that it a single supply is used. separate connections from a common de-coupling ca-
pacitor are used to teed the Micro-reader.
Note:
g The RF Module must not be supplied by Switched Mode Power Sup-
plies (SMPS). This is because most SMPS operate at frequencies
around 50 kHz. The harmonics of the generated field can interfere
with the TIRIS receiver. Theretore only use lineer regulated power
supplies. or SMPS with a fundamental operating frequency of 200
kHz or higher,
1.2.2 Antenna
The Micro-reader has been designed for use with a 47 pH antenna with a Q ol10to
20 to generate the exciter frequency of 134.2 kHz. Because of the low Q the system
does not need to be tuned.
WARNING:
CARE MUST BE TAKEN WHEN HANDLING THE MICRO-READER AS
HIGH VOLTAGES ACROSS THE ANTENNA PINS COULD BE HARMFUL
TO YOUR HEALTH.
1.2.3 Synchronization
There are two possible methods of wired synchronization:
1. Connect a pulse waveform to all RDEN- input pins of the Micro-readers to be
synchronized. The pulse would normally be at VSL. dropping to GND for 100 us
every 200 ms.
2, Connect all SYNC outputs to an 'Or‘ and then connect this as an input to RDEN~
of each Micro-reader to be synchronized.
Wireless synchronization of the Micro-reader is very effective at synchronizing to ad-
jacent readers. however problems may occur if the antennas are positioned such that
a transponder can be within range of two readers at the same time. in thls situation
one reader could synchronize with the transponder instead of the other reader.
When the WLSC input is active the Micro-reader is in wireless synchronization mode.
Wireless synchronization can also be switched on/off by a corresponding command
via the serial interface, During execution of this command it has priority over the
WLSC input. After the command execution the status of the WLSC input will be con-
sidered again.
1.2.4
1.2.5
1.2.6
Micro-reader - Reference Guide May ’00
Note:
@ It is not recommended to have both wired and wireless synchroniza-
tion switched on as synchronization could be unreliable.
We recommend the use of bus drivers for wired synchronization with
other Micro-readers and to prevent ESD damage.
Wired or wireless synchronization prolongs the cycle time by typically
20 ms.

When the Micro-reader is in idle mode it is possible to trigger a single charge-only
read with a power burst duration of 50 ms by taking the RDEN- pin to logic high for
100 us. The single read will start on the falling edge of the 100 its pulse.
it e transponder command is sent to the Micro-reader via the sol while RDEN- is in
a logic high state (waiting position), a falling edge would trigger execution of the com-
mand In waiting posltion the Micro-reader can only store one commend. This means
that it two commands were to be sent to the Micro-reader while It Is in the waiting po-
sition the second command will oven/vrite the first one.
Continuous Mode
When the CRDM input is active the Micro-reader goes into continuous charge~oniy
read mode using a power burst duration of 50 ms. The serial data input takes priority
over the CRDM input such that if a serial command is received It will be executed
regardless of the state ofthe CRDM input. After the execution of the serial data com-
mand the Micro-reader continues with the previous read mode.
In the default continuous read mode, only those valid R0, R/W or MPT IDs that differ
from the previously read ID; or valid IDs read after a “NO READ", are transferred via
the SCI (Normal Mode). The Micro-reader can be set to transfer all valid IDs that are
read (Line Mode) by means eta corresponding serial data command
Without synchronization the Micro-reader has a reading frequency of approximately
10 readouts per second using a power burst duration of 50 ms. Timing is given in
more detail in section 3.2,
Serial Communication
The two serial I/O pins are configured for 9600 Baud, 1 start bit, 3 data hits, no parity
and 1 stop bit; they can be connected directly to a communications driver to allow a
half duplex communication with a PC via its serial communications interface (for ex—
ample: R3232 or RS422).
The communications protocol is specified in Chapter 2.
Handshake
The Micro—reader accepts handshake commands Xnnlxo". When it receives an Xoff
(13m) the Micro»reeder stops its current operation and stops transmitting data via
the serial port. It stays in idle mode until Xon (t t nax) is received when it continues with
the previous mode/command. During this idle period the Micro-reader accepts com-
mands via the serial port. however, it welts tor its execution until X0" is received In
this idle period the Micro-reader can store only one command.

until the complete reading, programming or locking cycle is finished.
Input ior wired synchronization. Taking this pin to VSL acts as a
hold—oft for the Micro-reader‘s output stage preventing it from
transmitting until the input returns to GND. The Micro-reader only
samples this input at the start oi its own reading. programming or
looking cycle, this means that it the input goes to VSL after a cycle
is started, the cycle is not interrupted. RDEN is a high impedance
input and must be tied to GND via a suitable resistor (27 kOhm)
when It is not being used.
When the Mioro-reederis idle it is possible to trigger a single read by
taking the RDEN-pin logic high for 100 ms. The single read will start
on the falling edge ofthe 100 ms pulse.

Antenna pin for the connection of 47 pH, low Q antennas,
It is posSible to use antennas of lower inductance by connecting a
suitable capacitor between ANT1 and ANTCAP. This additional
capacitor (ceramic, 100 VDC) will be in parallel wlth the 30 nf
resonance capacitor on board the Micro-reader (see Figure 4 and
Appendix C).

Pin 21 is ground for the output stage.
Pin 22 is for connecting the positive supply voltage (5 V) for the
output stage.
Pin 24 is for connecting the positive supply voltage (5 V) for the logic
part.
Supplying pin 26 with a logic high signal causes the Micro-reader to
run in a continuous charge-only read mode (see section 1.2.5 for
more information}.
When Ihe CRDM pin istied to logic low, the Micro-reader is in an idle
state waiting for commands via the serial interlace or (or a trigger
signal (RDEN-) to start a single read out cycle. CRDM is a high
impedance input and must be tied to either VSL or GND via a
suitable resistor (27 kOhm).
Pin 27 enables or disables wireless synchronization. To enable the
wireless synchronization, pin 27 must be taken to VSL. When
wireless synchronization is enabled, the Micro-reader will try to
synchronize its transmit signals with any other readers in range. To
disable wireless synchronization pin 27 must be taken to GND, Pin
27 is a high impedance input and must be tied to either VSL or GND
via a suitable resistor (27 kOhm).
Wireless synchronization can also be switched on/olf by a
corresponding command via the serial interface. During execution of
this command it has priority over the WLSC input.
This output is set to logic high tor approx. 60 ms if a valid
transponder was read. It can be connected to an LED externally to
indicate the result of the read cycle.
Pin 30 is set to logic low when the RF-transrnitter is activated.
Supplying an external LED with this signal makes the status of the
Micro—reader Visible.

The 'Command FieId(s)‘ defines the mode in which the Micro-reader operales and
determines the operation that is to be carried out in the transponder. Depending on
the settlng of lhe relevenl bits, the corresponding information specified in the Date
Fields will be sent to the lransponder or not. Thus all functions of each particular tran-
sponder type can be executed (see 2.1.4 for further information).

Antenna Design
C.1 Introduction
This appendix gives an example of how you could construct an antenna to work with
the micro-reader, It also provides information about calculating the 0 factor and
adapting the inductance range.
The antenna properties should be:
0 factor less than 20
Inductance between 46 and 4B uH
Recommended maximum size 200 mm x 200 mm
(2.2 Antenna Construction
Item List:
, ”Will?“
1 Enamelled solid copper wire. 0.2 mm 21 g
2 Tape‘ 10 mm wide 20 mm
3 Block cloth tape, 12 mm wide 0.12 m
4 Spiroband, 3 mm diameter (124 m
5 Screened antenna lead 1 m
Method:
- Wind 15 turns of item 1 with a diameter of 75 mm.
- Leave about 50 mm tree at the ends, cross the wires (at the +/- 50 mm point)
and secure them together using the tape (item 2).
- twist the spriband (item 4) onto the coil that you haveiust made. leaving the
start and finish ends free,
— Strip the insulating braid back at the end of the antenna lead (item 5)4 Wrap
the start and finish ends at least three times around the bared ends and solder
the joints (the polarity is not important),
~ Tightly bind the soldered joints to the spriband using the cloth tape (item 3).
This method should result in a 47 pH antenna with a quality factor of
approximately 17 - 18,

Mlcro»reader - Reference Guide May ’00
6.3 Q Factor
If the antenna’s Q factor exceeds 20:
l. The output capacitors will be overloaded and long term damage could result.
2. The antenna may still be resonating when the response from the transponder is
received. Without built-in damping the data will not be correctly received.
3. The antenna may be detuned it there is any metal in the area.
The following formula provides an approximate method of calculating the Q factor of
the antenna;
Where: f = 13A200 Hz (Frequency = 1342 kHz)
L = Inductance (henry)
R = Series resistance (ohm)
Example.
The inductance (L) = 47pH
The resistance (R) = 22 Ohm.
Q _ z x n x134200 x 0.000047
‘ 2,2
= 39.636
2.2
=18
0.4 Adapting the Inductance Range
If your antenna is outside of the required inductance range of 46 to 48 pH, you can
adapt it to work with the micro-reader by adding an external capacitor to it, either in
series or in parallel. You can use this external capacitor to change the inductance
range by 1 5 pH.
You can work out the total resonance capacity using the following formula:
2 \
Ifthe antenna inductance is less than 46.1 pH you can add an extra capacitor (exter-
nally) to the antenna between pin 16 (ANTt) and pin 17 (ANTCAP). The formula to
work out the value of this capacitor is:
Cext = Cruz—301117
Ifthe antenna inductance is more than 479 uH you can add an extra capacitor in se-
ries with the antenna between pin 19 (ANTZ) and the antenna. The formula to work
out the value of this capacitor is:
Cw; 30nF
