Chapter 1
Introduction
This chapter describes Transponders and their functions, the purpose of the Postal
RFID System and its uses. It also gives information on the 95 Series RFID System
configuration principles.
Transponder Identification System
The purpose of a data capture or identification system that uses a Transponder as an
identification token is:
•
To automatically identify animate or inanimate objects having attached a
Transponder with an unique identifier
•
To ensure that information is available in a format that can be readily accepted by
a computer
•
To minimize the possibility of errors in the identification process.
The concept of Radio Frequency Identification (RFID) is presented in Figure 1-1.

RFID Specific Terms
RFID Specific Terms
Transponder
Transponders are devices that receive an excitation signal, and respond by
transmitting back a message. Transponders that are used in identification systems
are sometimes referred to as electronic tags or tags.
Excitation Signal
The excitation signal may be in the form of electromagnetic energy and can operate
anywhere in the RF spectrum from a low-radio frequency to infra-red light. It can also
have a special signature (pattern, coding, etc.) to avoid false or unwanted excitations.
When there is no excitation signal, the Transponder is dormant (in sleep mode).
Transponders do not transmit information involuntarily.
Response Signal
The Transponder’s response can be a separate RF transmission or a supplementary
modulation of the excitation signal. The response signal contains information that
allows you to identify each Transponder and the object to which it is attached. Some
or all of this information may be stored in memory that can either be pre-coded and
unalterable, or reprogrammable.
Reading Points
Reading Points are installed at strategic areas on the site where you want to identify
objects that are passing within a specified range. Reading Points generate the
excitation signal and receive signals transmitted by the Transponders. Data captured
from the Transponders is then transferred to the main computer. In so doing, the
Reading Point functions as a relay or an interface that transfers data from the
Transponders to the main computer and vice-versa.
Communication Links
When using Transponders and Reading Points, two wireless communication links
exist. They are: Uplink - from the Reading Point to the Transponder, and Downlink from the Transponder to the Reading Point.
RFID System
Automatic identification systems vary in their complexity. An example of a simple
system is a car-park barrier that provides automatic vehicular-access control. A more
complex example is a network of on-line Readers and Exciters that communicate with
a host computer that is managing an automated industrial facility.
Postal RFID System
The International Postal Corporation (IPC) required international end-to-end mail
performance monitoring to implement new management and financial control
systems. This monitoring and controlling is supported by an international agreement
known as REIMS (Remunerating Exchanges of International Mails).
The Postal RFID System was developed in response to the IPC’s requirements.
The main objective of the Postal RFID System is:
•
•
•
1-2 Introduction
To monitor the movement of the probe letters at key points in the system
To supply evidence of mailing system performance
To highlight problem areas.
95 Series RFID System Configuration Principles
By using a RFID system comprising of a population of Transponders and strategically
placed Readers and Exciters, you can electronically monitor the path of test letters
through the collection and delivery process, particularly at points between Postal
administrations and their agents.
Each probe letter includes a RFID Transponder bearing a unique identification. The
probe letters are posted, sorted, and delivered in the same way as normal letters. As
they pass pre-determined points en-route (Reading Points/identification zones), the
Transponders are identified. The collected information is then read and stored on
local computers. This information is downloaded on demand to a Central
Management System (CMS).
The Postal RFID System includes the following main specific equipment:
IMPORTANT
•
Transponders T95 carrying the identification data
•
Exciters E95 to generate an electromagnetic field that excites the Transponder
T95
•
Readers R95 to receive data transmitted by the Transponder T95 and to relay this
information via the RS-485 interface to the main computer
•
Power Supply TRM95 to power Readers R95 and Exciters E95 from the local AC
main supply.
Each piece of equipment can have different commercial models (Transponders T95B,
T95C, TRD95, and TBC95, PT21), but they behave similarly. This manual refers to
them as a generic T95 model.
95 Series RFID System Configuration Principles
The RFID System is highly configurable, allowing you to setup operational
parameters for the optimum performance of the System. The sections that follow give
some basic information regarding the 95 Series RFID System configuration. A
detailed description of the configuration, with a focus on an IPC implementation, is
given in Chapter 5, Configuration and Operation.
Communication Links
System Parameters
There are several communication links between the components of the 95 Series RFID
System. As a general rule, all equipment attached to a particular link must have the
same parameters settings to communicate. Some communication links can be
configured, others, however, have fixed configurations, as follows:
•
Reader-to-Transponder: excitation (LF=125.0 kHz) - configurable;
writing (infrared) - fixed configuration.
•
Transponder-to-Reader (UHF-433.92 MHz) - configurable.
•
Reader-to-Exciter and Exciter-to-Reader (RS485_COM, RS485_SGN) - fixed
configuration.
•
Reader- to-Main PC and Main PC-to-Reader (RS-232 or RS-485) - configurable.
Parameters controlling the 95 Series RFID System’s configuration are logically
organized in groups. For a detailed explanation on the meaning and usage of the
parameters, refer to the 95 Series RFID System Reference Guide. The parameters
Introduction 1-3
95 Series RFID System Configuration Principles
settings that control the hardware configuration, is described in Chapter 3, Theory of
Operation in the 95 Series RFID System Technical Guide. This chapter gives reasons
for using certain parameters for configuring the hardware.
System Code
A Reader R95 needs a System Code to function properly. You use the ISC parameter
to set the System Code the first time. The System Code is a specially encoded number
that distinguishes the RFID System from all other similar systems in use. By
obtaining your System Code from Kasten Chase, you are guaranteed a unique System
Code.
Reader Address
When a Reader is part of a network, it must have a unique address. The address is set
by the IAD parameter. Once the Reader has an address assigned, it will only process
commands with the address field matching the Reader’s address. In this way, you can
direct commands over the network to a specific Reader.
Real Time Clock
The Reader R95 has an on board Real Time Clock. Make sure that the date and time
is correctly set. The time can be queried and set using the IUT parameter. The time
must be adjusted on Jan. 1st and Feb. 29th.
Receiving UHF Data
The Reader needs to know the data format in which the Transponder is transmitting
information to properly receive and interpret the information. The Reader’s setting
can be checked and modified by the Group R parameters.
A simple method of matching an unknown Transponder with the Reader’s parameters
setting is given below:
1. Use the programming setup described in Chapter 6, Programming and Testing
the Transponder T95.
2. Query the Transponder. (See the Q command).
3. Check the Transponder’s parameters using the Group T parameters.
4.
Set an identical set of parameters for the Reader using the Group R parameters.
Reader Data Handling
Data that is captured from the Transponder is usually stored in an internal buffer. It
is then sent to the monitoring equipment either voluntarily (if DAR=Y), or in response
to a query command. You can customize the format and the fields using the Group D
parameters. By setting appropriate values, you can greatly simplify the
implementation of the monitoring software.
Reader Serial Port
When setting the serial port parameters, remember that communication with the
monitoring equipment can result in a bottleneck in the RFID System. We recommend,
therefore, using the highest baud-rate available. Also, the line turn-around delay
(STD parameter) can greatly degrade the RFID System’s performance. This
parameter must be set to 0, unless required otherwise. For more information on the
Group S parameters, refer to the 95 Series RFID System Reference Guide.
Reader Reset
There are two main ways to reset the Reader:
•
•
Hardware reset
Software reset.
For the hardware reset, switch off the Reader’s power supply for a least 5 seconds.
1-4 Introduction
95 Series RFID System Configuration Principles
For the software reset, press the RESET button on the Motherboard MBD95 twice, or
type the command:
:RESET
The software reset resets the Microcontroller. The hardware reset resets the
Microcontroller and runs a complete memory test.
Exciter Address
When an Exciter E95 is part of a network, it must have an unique address. You can
set the Exciter’s address in a binary format between 0001 and 1110, using the S1
switch on the EXT95SC board.
Once an address is assigned, the Exciter will only process commands with a matching
address field. In this way, you can direct commands in the network to a specific
Exciter E95.
Note
Addresses 0000 and 1111 are reserved for special modes of operation.

Mechanical Assembling
To assemble the Exciter E95, refer to the assembly drawing (M900121), and then
complete the following steps.
Assembling the LF
Antenna for E95
The antenna frame consists of five separate segments, each with the following
dimensions: two pieces - 0.4m long, two pieces - 2.0m long, and one piece - 1.0m long.
Each segment includes an aluminum tube with an internal rubber hose. The
segments are joined together using plastic corners. The antenna cable (7-wire cable)
runs through the rubber hoses inside the aluminum tubes.
To assemble the antenna, do the following:
1. Starting with one side of the antenna frame that is beside the plastic enclosure
(0.4 m segment), place the corresponding rubber hose inside the aluminum tube,
and run the antenna cable through the rubber hose. Run the cable through a
plastic corner, and secure the plastic corner inside the aluminum tube using a
rubber mallet.
2. Repeat Step 1 for each side of the frame, finishing with the last short segment
(0.4m). You should have a 1x2m rectangular aluminum frame with the antenna
cable inside.
3. Terminate the antenna frame with the plastic base connectors.
4. Place the 90° brackets on each ends of the frame, and secure the frame against the
plastic enclosure using M6 screws, washers and nuts.
5. Connect the antenna frame to the ground lead on the board, by securing the
terminal lug of the ground lead on the EXT95SC electronic board with one of the
M6 screws, as shown on the assembly drawing 600406.
Note
Always ensure that the ends of the antenna cable inside the plastic enclosure have the
following dimensions: one - 110mm long and the other - 360mm long. For more
information, see the drawing 600406.

Reader’s Power-up Sequence
Reader’s Power-up Sequence
To verify the Reader’s power-up sequence, do the following:
1. Turn on the power supply to the Reader.
2. Referring to Figure 5-1, check whether the relay on the MBD95 board
immediately clicks, and the green POWER LED is on.
3.
Check whether the Reader performs the following power-on test sequence: the red
DATA LED on the MBD95 board remains ON for 6-7 seconds. Afterwards, the
following sign-on message is displayed on the PC’s screen:

Notes
(c)Copyright DISYS Corporation
1989-1996.
1. If you did not assign a System Code identification number (SC) to the Reader, the
DATA LED will flash On and Off at a rate of 1.4 Hz. To set the System Code, type:
ISC=[your SC] 
2.
If a string of unrecognizable characters appears on the PC’s screen, it means that
the communication link between the Reader and the PC is not set properly. Run
the Learning Procedure, as described below, to establish the correct settings.
Learning Procedure (Optional)
This a special mode of operation, specifically designed to allow a Reader to
communicate with the PC to which it is attached, by adapting itself to the serial frame
format that the PC is using.
To force the Reader into the learning mode, follow the steps below. (See Figure 5-1).
1. Press the RESET button once.
2. Verify whether the DATA LED flashes at a rate of 2 Hz. This means that the
Reader is in the learning mode, and is waiting to determine the frame format sent
by the PC.
3. Send a few characters to the Reader, for example, LYNGSOE.
4. When the learning process is finished, the DATA LED will start flashing at 1.4 Hz
rate and the following message will be displayed on the PC:
Learned: rate, parity, bits
where:
rate: is the serial data rate (baud) expressed as a numeric value, for example,19200.
parity: is a single character that reports the parity bit: N for no parity, Y for parity.
bits: is a single digit (7 or 8) that reports the number of bits per character.
5. Check the values of the Reader’s current serial communication configuration by
Configuration and Operation 5-3
Resetting the Reader
using Group S parameters. You can change the settings for the PC or Reader so
that the settings match each other. If you modify the Reader’s parameters, you
must save them before leaving the learning mode. For more information on this
procedure, see Storing the Reader’s Configuration on page 5-13.
6. Press the RESET button again to exit from the learning mode.
7.
Notes
The DATA LED will stop flashing.
1. The serial communication configuration for an IPC application has the default
values of the Group S parameters. For more information on the Group S
parameters, refer to the 95 Series RFID System Reference Guide.
2.
If the noise and interference level on the UHF channel exceeds the carrier
threshold or a Transponder is transmitting information, the DATA LED will start
flashing at a faster rate.
Resetting the Reader
There are 2 ways to reset the Reader (see Figure 5-1):
•

IVN 
The response should be:
IVN=CRM95 V_.__, BUILT: __/__/__ __:__:__.
Note
5-4 Configuration and Operation
You can upgrade the Reader software, if necessary. For more information on
upgrading the software, refer to Appendix D, Reader Software Upgrade Procedure.
Setting Up the Exciter’s Address
2. Check the System Code (SC), by typing:
ISC 
The response should be:
ISC= [your SC]
If the displayed System Code is not identical with the application system code
number, replace the Reader and report the problem to Lyngsoe.
3. Check the Receiver’s Serial Number (SN), by typing:
ISN [your SN]
If the displayed serial number is not equal to the serial number on the Receiver’s
CRM95 board, set it to the correct value. For example, if the SN is U123456, then
type:
ISN=U123456
4. Store the new SN and/or SC parameter values, by typing:
:CONFIG:STORE 
:RESET 
5. Check the correct values of the IVN, ISC, and ISN parameters, by repeating
Steps 1 to 3.
6.
Switch off the LF field, by typing:
C
Setting Up the Exciter’s Address
Your next step is to setup an address for each Exciter by using the S1 slide switch on
the EXT95SC board, as shown in Figure 5-2 below.

Figure 5-2: Setting Up the Exciter’s Address
Configuration and Operation 5-5
LF Transmitter Output
The addresses must be sequential between 1 and 14. For example, if there are 4
Exciters, they must be assigned addresses 1, 2, 3, and 4. Use the S1 switch to set the
address to binary format. For example, in binary format:
•
•
•
•
address 1 is 0001 2
address 2 is 0010 2
address 3 is 00112
address 4 is 0100 2
If the switch is in the ON position, the bit is set to 1. Otherwise, the bit is set to 0.
Note
Addresses 00002 and 11112 are reserved for special modes of operation.

1. Connect the power to the Exciter.
2. Check the current parameter settings for the excitation mode and write down the
value of the following parameters: RCS, RES, REM, RET, HCC, HCS, HE0, and
HE1.
Note
To determine the value of a parameter, for example, HE1, type the command:
HE1 
5-6 Configuration and Operation
LF Transmitter Output
The Reader will respond with the parameter value, for example,
HE1=6
where 6 is the value for the HE1 parameter.
3. Set the Continuous DC Mode type of execution, by typing:
RCS=N 
RES=N 
REM=C 
RET=D 
Note
If a parameter already has the wanted value (determined in Step 2), you do not have
to reset it.
4. Turn on the excitation field, by typing:
B 
Check the TAP voltage [VTAP] at the terminal block TB2 on the EXT95SC board
(see Figure 5-3) using an oscilloscope. The signal must be a continuous
unmodulated carrier of 128.25 kHz with a peak-to-peak amplitude of
VTAP = 100 ± 20 V pp.
Note
When more than one Exciter 95 is used to create a wider excitation zone, a magnetic
coupling can appear. The phenomenon is explained in Chapter 4, Setup Guidelines in
the 95 Series RFID System Technical Guide. The coupling generates an unwanted
amplitude modulation with a frequency of several Hertz, the modulation depth
depending directly on the coupling. The installer has to monitor the TAP signal and
adjust the position of the E95 frames to obtain a minimum unwanted modulation
depth. The installer can increase the distance between frames, level the frames in the
same plane, or place the frames with the shorter sides (1m) in parallel. The minimum
amplitude of VTAP due to unwanted modulation must be larger than 60Vpp.
5. Turn off the excitation field, by typing:
C
The TAP voltage amplitude should be zero.
6. Turn on the LF field again, by typing:
B 
The TAP voltage signal should have the same value as measured in Step 4.
7. Set the wanted excitation mode.
To set a specific excitation mode, refer to Appendix C, Excitation Modes. If you
want to return to the initial excitation mode as determined in Step 2, you have to
restore the values of the parameters modified in Step 3.
Configuration and Operation 5-7
Configuring the Reader
For example, Lyngsoe recommends the following parameter values for the
Conditional Switching AC mode (CSAC) for the IPC installation:
RCS=Y; RES=Y; REM=C; RET=A; HCC=8; HCS=7; HE0=18; HE1=6
These parameters all have the default values.
8. Check the excitation field pattern as set in Step 7, by monitoring the TAP voltage.
For example, if the IPC’s CSAC mode was set and the Reader did not receive a
valid message, the TAP voltage has the following repetitive pattern: a carrier of
128.25 kHz modulated ON/OFF with 610Hz for 60 ms, followed by no signal for
180 ms.
9. Save the excitation mode set in Step 7, by typing:
:CONFIG:STORE 
:RESET 
10. Check the parameter values set in Step 7 again.
11. Check the auto-diagnostic feature, by typing:
:DAR=Y 
:TEST:EXCITER k 
where k is the decimal address (1, 2, 3, ...) of the Exciter that you want to test.
The response should be 00, followed by a number (between IP-2 and IP) of
messages from the Test Tag.
12. Turn off the excitation field again, by typing:
C
13. Check the auto-diagnostic feature, by typing:
:TEST:EXCITER k 
The response should be C9.
14. Repeat Steps 1 to 13 (inclusive) for each Exciter that is connected to the Reader.
Configuring the Reader
The Reader’s basic configuration covers the following group of parameters:
•
•
•
•
Data buffering/reporting configuration Hardware configuration
Instrument generic configuration
Tag data reading configuration
Group D parameters
Group H parameters
Group I parameters
Group R parameters
For more information on these parameters, see the 95 Series RFID System Reference

5-8 Configuration and Operation
Setting Up the Carrier Threshold
Note
You can set these parameters for each particular application to optimize the
functionality of the Reader and the RFID System.
Setting Up the Carrier Threshold
Warning
Before starting this procedure, you have to enable the auto-report and set the data
report in ASCII format, by typing the following:
DAR=Y
DHX=N
To setup the Reader’s carrier threshold, do the following:
1. Switch off the excitation field, by typing:
C
2. Set the Receiver’s signal-to-noise ratio, by typing:
RSS=10
Note
You can set other values for the RSS parameter. Lyngsoe recommends using a value
between 10 and 20 for the RSS parameter.
3. If you are using Diversity, enable it by typing:
HAD=Y
Ensure that both UHF antennas are connected. If you are not using Diversity,
disable it by typing:
HAD=N
Ensure that only the right UHF antenna is selected (see the HAS parameter).
4. Check the noise level on the UHF channel, by typing:
HNL
The HNL value should be between -107 to -95dBm.
If the HNL value is higher than -95dBm, check if there are unwanted
transmissions on the UHF channel (433.9 MHz). Pay special attention to
Transponders or Exciters in close proximity to the Reader; these can accidentally
transmit data that can be received by the Reader.
If the HNL value is lower than -105dBm, check its value without the UHF
antennas attached. The difference between these two readings must be greater
than 3dB.
Configuration and Operation 5-9
Setting Up the Carrier Threshold
5. Set the carrier threshold, by typing:
S 
or
:CONFIG:THRESHOLD
Note
If the Reader resets itself, repeat the procedure from Step 1.
6. Monitor the DATA LED for at least 10 seconds. The LED must not flicker. If it
does flicker occasionally, increment the RSS parameter value by one. Go to Step 5.
IMPORTANT
For a normal setup, the value of (HNL+RSS) must be less than - 85 dBm.
If the noise level is higher than -95 dBm, disconnect the UHF antennas from the
Reader, and check whether the HNL value drops below -107 dBm. If this occurs, it
means that there is unwanted transmission on the UHF channel. To correct this
situation, refer to Chapter 4, Setup Guidelines in the 95 Series RFID System
Technical Guide.
7. Place your Test Transponder T95 1-2 m away from an Exciter that is controlled by
the Reader you are configuring. For more information about identification zones
and the Test Transponders, refer to Chapter 4, Setup Guidelines in the 95 Series
RFID System Technical Guide.
8. Start the excitation field, by typing:
B
9. Verify that the DATA LED is flickering, and check whether the Test Transponder’s
messages are displayed on the PC’s screen.
If data is not displayed, check the Reader’s parameter configuration, and follows
the troubleshooting instructions in Chapter 7, Troubleshooting.
If the number of displayed messages is below n=IP-2, check the carrier threshold
and try to adjust it again. Go to Step 1.
10. Remove the Test Transponder from the field and make sure that it is no longer
transmitting by ensuring that the DATA LED is not flickering.

rr is the Reader’s address. If Reader’s address is 1, rr = 01.
kk is the Exciter’s address. If the Exciter’s address is 1, kk = 01.
2. Turn off the LF field, by typing:
C
3. Program the Exciter Test-Tag, by typing:
:TAG:MATCH:EXCITER k
where k is the address of the Exciter you want to program.
If the response is not 00, the Exciter is not programmed. Repeat this command
several times, waiting at least 3 seconds between retries.
Note

The Carrier Threshold level setting is correct if the new HNL level displayed is
smaller than or equal to the level displayed in Step c. If not, check for unwanted
transmission on the UHF channel. You should also refer to Chapter 4, Setup
Guidelines in the 95 Series RFID System Technical Guide.
3. Verify that an Exciter that is controlled by a Reader communicates with the Main
PC:
a) Delete all Tag records from the Reader’s buffer, by typing:
@r :DATA:PURGE
b) Confirm that the Reader’s buffer is empty, by typing:
@r D
or
@r :DATA:REPORT
The Reader must report a Null value.
Note
For an IPC application, the data structure conforms to the ANS.1 standard. If the
Reader’s buffer is empty, the Reader sends a Null value of $0500. In ASCII format,
the Null value is { }.
c)
Switch on the LF field, by typing:
@r B
d) Send a Test Exciter command, by typing:
@r :TEST:EXCITER k
where r is the Reader’s address and k is the Exciter’s address. The correct
Exciter’s response is 00.

Preventive Maintenance
Chapter 7
Troubleshooting
This chapter describes maintenance and troubleshooting procedures that you must
follow when using the 95 Series RFID System. These procedures complete the
troubleshooting information given in Chapter 5, Configuration and Operation, for the
initial system installation and configuration.
Preventive Maintenance
By using special commands, built-in Self Diagnostic circuits can check any part of the
system and report an error code, if necessary. Depending on the error code received,
the service technician will know the piece of hardware that is malfunctioning, and can
immediately take corrective action to remedy the situation.
All units have a warranty seal placed on their enclosures. Removal of this
seal will void the warranty.
General Guidelines
Below is a list of some assumptions and guidelines:
1. The chapter assumes that repairs for any electronic assemblies are not made on
site. Unless otherwise stated, if a specified condition cannot be met, the electronic
assembly must replaced and returned to the manufacturer for repairs.
2. For a complete technical description of the 95 Series RFID System, refer to the
95 Series RFID System Technical Guide. For a detailed description of the
commands and parameters used to configure or to control the 95 Series RFID
System, refer to the 95 Series RFID System Reference Guide.
3. Information regarding the 95 Series RFID System’s configuration and operation is
described in Chapter 5, Configuration and Operation.
4. The locations of the DATA LED, the POWER LED, and the RESET button are
shown in Figure 5-1.
5. All the reference to commands are made assuming that the Reader’s address is 0.
Troubleshooting 7-1
General Guidelines
The following table describes several possible failures for the 95 Series RFID System,
and the troubleshooting steps to correct them.
Problem
No communication
with a Reader.
Symptom
Reader does not
respond to any
command.
Probable Cause
1. Reader has an
incorrect address.
Solution
1. Check whether the Reader responds
to commands using different
addresses, by typing the following:
@1 IVN, @2 IVN,
@3 IVN. When a correct
address is sent, the Reader will
respond with its version number.
2. If, by using a specific address, you
are able to communicate with
Reader, use this address or change
the address to another value.
3. If after checking all possible
addresses (up to 31), you still cannot
communicate with the Reader, check
Probable Cause 2.
2. Faulty communication
line between the
Reader and PC.
1. Open the Reader’s enclosure and
connect the PC directly to the
Reader using the RS-232
communication line. See Connecting
the RS-232 Communication Line on
page 2-2.
2. Switch off the Reader’s power supply
for at least 5 seconds, then perform
the steps in the Reader’s Power-up
Sequence on page 5-3.
3. If the Reader performs the power-on
test successfully, press the RESET
button once. Check whether the
DATA LED starts flashing at the
rate of 2 Hz.
4. Press the RESET button again.
Check whether the DATA LED stops
flashing.
5. Check whether the Reader is
responding to local commands by
typing: @r IVN, and pressing
, where r is the Reader’s
address. The Reader must respond
with its version number.

page 2-2.
2. Switch off the Reader’s power
supply for at least 5 seconds, then
perform the steps in the Reader’s
Power-up Sequence on page 5-3.
3. If the power-on test is successful,
the DATA LED should start flashing
continuously at the rate of 1.4 Hz.
4. Check the System Code number by
typing: ISC, and pressing .
If the Reader responds with ISC =
0, setup the Reader’s System code
again by typing: ISC = your SC, and
pressing .
5. If the Reader restored one of its
parameters to the default value, all
other parameters are also reset to
their default values. Check and
reset all the application- specific
parameters to their original values.
6. Check the HV0 and HV1 parameter
values. If these parameters have
default values 73 and 105
respectively, you must set them
again using the correct values from
Lyngsoe’s database.

Step 2 - Set up the Carrier Threshold
for the Reader.
4. If the Reader reports a channel noise
level below -95dBm, but you are still
not receiving the Transponders’
messages, check the noise level
reported by the Reader with and
without UHF antennas connected. If
the noise level is identical or varies
slightly (±1 dBm), replace the
Reader.
5. If the Reader reports a noise level
(HNL) above -95 dBm, the unwanted
transmission is on the UHF channel.

capability of each Reader R95.
Object Sensor
Monitoring
An external object sensor device can switch the excitation field On and Off.
Driving Output
A Single Pole Double Throw (SPDT) relay contact is available to drive external
devices. The relay is activated each time the Reader receives a correct message.

Transmit System Code
After a valid excitation, the T95 transmits the initial number of messages defined by
the IP parameter, followed by an extra number of messages (up to the RC) for as long
as the excitation exists. Then it goes to sleep.
There is a random delay called InterMsgDelay that occurs between two consecutive
messages. This is implemented to ensure that the delay time does not repeat itself
before 32 messages have occurred.

Message Format
The following is the method of evaluating the maximum transmission time for the
T95:
Number of bytes per message: TXBytes = SC + UD + CRC + Flag + Key
Number of bits per byte: BitsPerByte = 12 for DR4, and = 11 for DR3
Number of bits per message: TXBits = Sync + BitsPerByte*TXBytes
Bit duration: BitLen = 1/DR
Message length: MsLen = 0.0007 +TXBit*BitLen
Intermessage constant: InterMsgUnit =
(UD + Flag)*0.0003066, for DR4;
(UD + Flag)*0.0005657), for DR3
Intermessage delay: InterMsgDelay = [SD +RND(0…31)]*InterMsgUnit;
(RND - random value)
Maximum number of transmitted messages: NM = IP +RC; if LT = N
Total transmission time: TXTime = NM (MsLen +(NM-1) (InterMsgDelay)
The following tables present the maximum number of messages (NM) that can be
transmitted in five seconds, using different sets of parameters for the T95.

Upgrading the Firmware
Appendix D
Reader Software Upgrade Procedure
This appendix describes the procedures for upgrading the Reader R95 (P/N 600405)
main software using the serial interface RS232 or RS485. This software controls the
functionality of the Microcontroller placed on the Receiver assembly CRM95
(P/N 500056). This procedure refers particularly to the upgrading process for software
version 1.68.02.
Upgrading the Firmware
Upgrading the firmware involve the following steps:
1. Setting the Reader’s Address to 0
2. Saving parameters: HV0, HV1, ISC, ISN
3. Upgrading the firmware itself by using:
a) The RS232 interface
or
b) The RS485 interface: 4-wire communication line or 2-wire communication line
3. Restoring parameters: HV0, HV1, ISC, ISN
4. Setting the Reader’s Network Configuration
5.
Setting the Reader’s
Address
Final instructions
To set the Reader’s address, do the following:
1. If the Reader already has an address, for example r, then set this address to 0 by
typing the following commands:
@r IAD=0
@r :CONFIG:STORE
@r :RESET
For more information, refer to Storing the Reader’s Configuration on page 5-13.
2.
Check whether the Reader’s address is 0, by typing the following command:
IVN
The Reader must respond with its software version number. If not, repeat Step 1.
Reader Software Upgrade Procedure D-1
Upgrading the Firmware
Follow these steps:
Saving Parameters
1. Write down the values of the following parameters: HV0, HV1, ISC, ISN.
To determine a parameter’s value, for example, HV1, type the following command:
Note
HV1
For example, the Reader responds:
HV1=125
where 125 is the parameter value.
2.
If the Reader was already configured, write down all parameters whose values
differ from the set default values. For more information, refer to Chapter 1, Quick
Reference in the 95 Series RFID System Reference Guide.
For example, for an IPC installation, write down the values for the following
parameters: DCI, DRI, HTL, RCC, RSS.
Using the RS232
Interface
Follow these steps:
1. Connect your PC (COM port) to the Reader R95 (RS232 interface) using a
standard RS232 cable. For more information, refer to Setting Up the Reader/PC
Connection on page 5-2.
2. Start the upgrading procedure by typing the following command:
:CONFIG:FIRMWARE:LOAD
or type the following shortcut:
F
3. Start XMODEM, send protocol on the PC, and then send the new firmware file.
Lyngsoe recommends having the new file on your hard drive and not on a floppy
disk.
4. Wait until the transfer process is complete. If the 95 Series RFID System aborted
the transfer process, repeat Step 2.
5. If the downloading process was successful, wait for the Reader to reset - it takes
about 5-7 seconds. For more information on the Reader’s power-up sequence, refer
to Reader’s Power-up Sequence on page 5-3. If the Reader did not reset properly
and did not send a sign-on message, then switch the Reader’s power supply Off
and then On.
6. To verify whether the upgrade process was successful, type the following
command:
IVN
D-2 Reader Software Upgrade Procedure
Upgrading the Firmware
The Reader must respond with the new firmware version number:
CRM95 V1.68.02, BUILT: 02/03/98 13:01:12
If not, repeat the procedure from Step 2.
7.
If after completing Step 5, you still cannot communicate with the Reader, replace
the Reader with another unit and return the faulty one to Lyngsoe.
Using the RS485
Interface
4-wire
Communication
Line
Follow these steps:
1. Connect your PC (COM port) to a Converter RS232/RS485. Connect the 4-wire
communication line to the Converter (RS485 side). For more information on the
communication line connection to the Reader, refer to Connecting the RS-485
Four-Wire Communication Line on page 2-4 and Setting Up the Reader/PC
Connection on page 5-2.
You can have a different assignment for the RS485 interface on the Converter
side. Use the following conventions for the connections between the Reader R95
RX+; Z
RX-.
and the PC: A TX+; B TX+;Y
2.
To upgrade the Reader’s software, follow steps Steps 2 - 5 in Using the RS232
Interface above.
Using the RS485
Interface
2-wire
Communication
Line
Follow these steps:
1. Connect your PC (COM port) to a Converter RS232/RS485. Connect the 2-wire
communication line to the Converter (RS485 side). For more information on the
communication line connection to the Reader, refer to Connecting the RS-485 TwoWire Communication Line on page 2-3 and Setting Up the Reader/PC Connection
on page 5-2.
You can have a different assignment for the RS485 interface on the Converter
side. Use the following conventions for the connections between the Reader R95
and the PC: A TX+; B TX+;
Or as an alternative: Y
RX+; Z
RX-.
Place the wire jumpers between terminal A
and TXRX- respectively.
Y, and B
Z; and TX+
RX+
2. To control the RS485 interface on a 2-wire communication line, you must use the
special software on the PC to allow hardware flow control. For example, Lingso’s
RS485 software to communicate with the Reader and Readerfw to upgrade the
Reader’s software. For more information on the software, refer to the Lingso
documentation.
3. To upgrade the Reader’s software, follow steps Steps 2 - 5 in Using the RS232
Interface above.
Reader Software Upgrade Procedure D-3
Upgrading the Firmware
Restoring Parameters
Follow these steps:
1. Verify whether parameters were erased during the upgrade procedure, by typing:
ISC
2. If the Reader responds with
ISC=0
then the original parameter values were erased and they were set to their default
values.
3. Reset the parameters HV0, HV1, ISC, ISN to their original values prior to the
upgrade process. You recorded them during the Saving Parametersstep.
Note
a) Firmware V1.68.02 ignores leading zeros for integers.
b) If the Reader was already configured on the site, you have to restore all
application parameters queried during the Saving Parametersstep, or restart the
configuration process as described in Chapter 5, Configuration and Operation.
3.
Check the values of the new parameters that were introduced by this software
version. For example, For an IPC installation, the following parameters must
have the default values as follows:
HCC=8, HCS=7, HE0=18, HE1=6, RCS=Y, RES=Y, SFC=N
Setting the Reader’s
Network Configuration
To set the Reader’s network configuration, do the following:
1. Set the Reader’s address to it initial value (see step 1 inSetting the Reader’s
Address): by typing:
IAD=r
2. Store the Reader’s parameters, by typing:
:CONFIG:STORE
3. Reset the Reader, by typing:
:RESET
4. Verify that the Reader is functioning properly, by typing:
@r IVN
where r is the Reader’s address. The Reader must respond with its software
version number.
5.
Verify that the parameters set in the following sections are correct:
• Steps 2 and 3 from the section, Restoring Parameters above.
• Step 1 in this section.
D-4 Reader Software Upgrade Procedure
Upgrading the Firmware
Final Instructions
1. You must repeat this procedure for each Reader R95 that is installed on the site.
2. Lyngsoe recommends using the RS232 or RS485 4-wire communication line to
upgrade the Reader’s software (these are more reliable communication links).
3.
For more information on the Reader’s R95 configuration, see Chapter 5,
