1 Introduction.

A high level of performance, security, reliability and convenience is required in various control and monitoring systems. TRANSIT

a broad range of tags in all environmental conditions.

TRANSIT



is based on proven microwave technology in the 2.45 GHz ISM band and allows identification of

tags at a distance up to 10 meters, even at high speeding passage. The NEDAP TRANSIT frequency identification equipment using modulated backscatter. In this method, the tags send there code to the reader by modulating and reflecting the signal transmitted by the reader. To reduce the influence of unwanted reflections, NEDAP applied circular polarization, which also allows orientation freedom of the tags.



TRANSIT

combines microwave identification and inductive identification in one unit. The system has the

possibility to identify vehicle and persons caring NEDAP XS-cards. For this purpose a small inductive antenna can be connected to the reader. (Reflex-130) The combination of the small inductive antenna with TRANSIT

called the Gate-Master



TRANSIT

system has a wide range of tags for various applications. Lithium batteries energize the tag circuit, which gives lifetimes up to 10 years. Heavy-duty tag is developed for vehicle applications. The Window-tags can be mounted easily behind the windshield of a vehicle. The Booster-unit is a special Window-tag that can hold a NEDAP inductive identification card. The booster reads this card after activation by the driver. The information from the card is then transmitted to the microwave reader.

Combi-booster is a combination of the Window-tag and the Booster-unit, which makes the identification of driver and vehicle possible. Pocket-tag is a microwave tag intended for the identification of people on large distances.

1.1 Characteristics.

The TRANSIT snake eye screws in the cover using a special tool can open this cover. After opening the unit the major components of the system are becoming visible. In the cover the Transceiver-unit is located, on the bottom of the stainless steel housing the Power-supply-unit is located. On the Power-supply-unit one of the optional communication boards can be placed. The backside of the unit hosts three PG-adapters respectively two PG-9, to be used for data communication cables, and one PG-13 adapter to be used for Mains connections.

2.1 Installation.

The TRANSIT reader can be installed in any position. Normally the reader shall be mounted in a horizontal position, then the coverage area in the horizontal plane is maximized. In some applications a vertical installation is required to make use of the smaller beam width in the vertical plane. The mounting brackets which make rotation in the vertical and horizontal plane possible is standard included in every TRANSIT.

The following mast mounting part is available for the TRANSIT.

3 Communication interfaces.

3.1 Connections to inductive readers.

The TRANSIT features two ways to connect it to external inductive NEDAP readers.

• Bringing the 120 kHz antenna signal of the external inductive reader to the TRANSIT and connecting it to

120 kHz-MOD connector of the Power supply unit (K1-1 and K1-2). The TRANSIT will modulate the received tag data on the 120 kHz antenna signal of the external inductive reader. The TRANSIT looks for the external inductive reader as an antenna. This feature makes the application of the TRANSIT simple in existing installations. To optimize the quality of the modulating signal the modulation depth can be selected in accordance with the type of receiver used in the external inductive reader. The U-Link setting: “ Inductive Mod select, K-13”, on the Power supply unit allows for the selection between voltage- or current coupled receivers. Contact NEDAP when in doubt which kind of external inductive receiver you want to connect to the TRANSIT system.

• Remember that when using the modulation function of the TRANSIT on the 120 kHz antenna signal of an

external inductive reader, to select external antenna (tuning) on this inductive reader. For the Accessor III-A and Accessor III-B for example this shall be realized by setting J1 in the external position.

3.2 Connections via the special code emulation outputs.

• The outputs OUT-1, OUT-2 and OUT-3 used for the emulated output for Wiegand 26, Omron, Barcode

and others are vulnerable for large potential differences. Care shall be taken to connect always the ground of the receiving system to the TransIT and use shielded cable.

3.3 Removing the optional communication boards.

• Remove the optional communication boards only when the TransIT is disconnected from the mains supply,

not doing this will damage the communication board.

4 APPLICATION INFORMATION

4.1 Available embedded software.

The TRANSIT communication features are defined by the firmware loaded in to the micro controller located on the Power supply unit PS-270. The micro controller is a Micro Chip PIC 16F876-20I / SP

(NEDAP Art. No.: 2802260).

For every firmware version an installation guide is available. The firmware can be loaded and upgraded in the PIC using a special software tool.

Contact Nedap for the possibilities.

4.2 Coverage area.

Transponder

Maximum

range 10 m

Line of sight

45 °

5 m

The TRANSIT system operates in the 2.4 to 2.45 GHz ISM band. The labels used with the TRANSIT system are all equipped with lithium battery’s to power the internal logic. The labels do not contain a transmitter but are using the received power from the reader, after modification, for re-transmission to the reader. This principle is called modulated backscatter The labels are so called field modifying devices. The received RF power from the reader is modulated with the data from the chip containing the ID-number. To read a label there has to be a line of side to the label from the reader. Most synthetic materials are transparent for RF energy with little attenuation and are forming no obstruction. Snow and ice are no problem as long as it is in crystal form. Closed water films are a problem for the detection range. Heavy rain shall be no problem as long as there is no closed water film on the TRANSIT front cover or on the label. To reduce the influence of unwanted reflections circular polarization is used, this brings also rotation freedom for the label. Placing the labels on metal surface is not influencing the read range. One has to keep in mind that the misalignment is most of the time present in two planes. This makes simple evaluation of the coverage area difficult. A computer model has been developed in which most geometry’s can be evaluated. Contact Nedap when in doubt.

The antenna diagram of the TRANSIT has a vertical beam width of 40° and a horizontal beam width of 80°. The labels are having a symmetrical diagram, 80° in the horizontal and vertical plane. The coverage area is based

on the combination of the two diagrams. When defining the reading range between reader and label one should take in account the misalignment between reader and label. Good practice is to reduce the read range by a factor of two when the label is on the –3 dB points of the reader antenna and the normal on the label still parallel to the main axes of the reader.

One has to keep in mind that the misalignment is most of the time present in two planes. This makes simple evaluation of the coverage area difficult. A computer model has been developed in which most geometries can be evaluated. Contact Nedap when in doubt. In par. 4.5 the detection area for a number of practical situations is given.

Version: 1.0, September 19, 2002 4 – APPLICATION INFORMATION

4.3 Speed limitations.

The maximum speed a transponder can pass the reader antenna and the transponder can be read is depended on the following factors:

Item Typical value

• Length of the detection trajectory.

• Distance between reader and tag.

• Number of valid frames needed for valid read.

• Length of code.

• Data rate

• Frame time

In this situation a maximum speed of 200 km/hour can be allowed. For every other geometry one should carefully consider the above mentioned parameters before a specification on the maximum speed is defined.

This speed can ONLY be obtained with firmware in the 54 bit detection mode, see firmware user manuals.

4.4 Using more systems at the same location.

When two or more systems are within a range of 15 meters, these systems should have a frequency offset of at least 600 kHz with respect to each other. The frequency should be factory set. When in doubt or when two readers are ‘looking’ to each other, frequency offset is recommended. This frequency offset has to stay within the local radio regulations.

When two readers are heaving a frequency offset they can be mounted close together and they can read the same label at the same time.

Version: 1.0, September 19, 2002 4 – APPLICATION INFORMATION

4.5 Read range control TRANSIT-SUB. (Art. 7800150)

Until now to only possible way to reduce the reading distance of the TRANSIT in a controlled way was the use of so called reference transponders. A transponder without the correct customer code was placed in the reading area in such a way that only transponders which had a return signal stronger then this reference transponder could be recognized by the TRANSIT.

Due to the fact that it is not always possible to find a good position for a reference transponder or due to the fact that it is not possible to use a reference transponder from a cost or esthetical stand point the TRANSIT SUB ( Squelch Upgrade Board) was developed.

TRANSIT SUB is a small PCB board which can be build into any TRANSIT.

TRANSIT SUB makes use of the already available AGC voltage (Automatic Gain Control Voltage) present in the Transceiver unit. This AGC- voltage represents the received signal strength of a transponder in front of the TRANSIT. When the orientation is fixed and no changes are present in the propagation path when the transponder is approaching the TRANSIT, this AGC voltage is a good measure for the distance between TRANSIT and transponder.

For the TRANSIT’s equipped with the PS-270 Power-supply and the firmware P-61, Q-70 and P-70 there is the possibility to set the squelch reference level by means of commands via the serial data communication channel when the DC2/DC4 asynchronous protocol is selected.

4.5.1 Content TRANSIT retrofit kit.

• 1x Printed circuit board TRANSIT SUB. (article 7800150)

• 3x Adhesive printed circuit board mounting supports.

• 1x 10 wire flat wire cable of approximately 100 mm.

• 1x 6 wire flat wire cable of approximately 100 mm.

• 3 colored wires for connecting the TRANSIT SUB to the PS-270 power supply unit.

WARNING:

When the TRANSIT SUB is placed and minimum squelch level is selected the maximum read range

can be shorter then without the TRANSIT SUB.

Version: 1.0, September 19, 2002 4 – APPLICATION INFORMATION

4.5.2 Theory of operation.

When a transponder is moving towards the TRANSIT the received signal strength will change as function of distance. It should be clear that also tag orientation with respect to the TRANSIT reader determines the received signal strength. The AGC voltage (U-agc, agc = automatic gain control) is proportional to the received signal strength. TRANSIT SUB compares this voltage to an user settable reference voltage. This reference voltage is called the squelch level (SQ-level). When U-agc < SQ-level the squelch is active (SQ-ON) and the received transponder signals are suppressed. When Uagc > SQ-level the squelch is not active (SQ-OFF) and the received transponder signals are normally processed.

U-agc

SQ-level

4.5.3 Squelch level setting.

The TRANSIT SUB has two ways of setting the squelch level (SQ-level); locally or remotely . Locally the squelch level can be set by means of potentiometer P-2 when the U-links K-7 and K-6 are set for position 2. Remotely the squelch level can be set by means of software commands, when the U-links K-7 and K-6 are set for position 1, which are controlling a so called DCP (digitally controlled potentiometer). The DCP has 100 positions and controls in this way a dynamic range of approximately 70 dB which means per step 0.7 dB in transponder return signal. Due to the fact that there is no linear relation between the transponder return signal and the distance the following relation between DCP step and distance is valid.

Transponder Distance

Change in distance for 1

step DCP in cm

2 10

4 15

8 25

The DCP rate of change when commanded up or down can be selected between fast and slow. Default is slow.

To step through the complete dynamic range (100 steps) between 100 and 50 seconds is needed in SLOW mode.

To step through the complete dynamic range (100 steps) between 20 and 17 seconds is needed in FAST mode.

4.6 Typical situations.

4.6.1 Introduction.

In the following diagrams a contour plot is shown of the received label signal. This contour plot gives always the top view of the situation. The position of the reader is always at 0,0. The label is positioned in a area of 10 by 10 meter. The scale of the plot is such that every square has a dimension of 1 by 1 meter. The minimum signal needed from the label is –100 dBm. This means that the area inside the –100 dBm contour represents the detection area.

The following parameters are used within the examples:

Parameter Description.

R-height Mounting height of the TRANSIT reader with respect of the ground.

D-angle Angle over which the reader is rotated in the vertical plane. When D-angle is

0 degrees the reader ‘looks’ parallel to the ground. When D-angle is 90 degrees the reader is ‘looking’ straight down.

A-angle Angle over which the reader is rotated in the horizontal plane.

L-height Mounting height of the transponder with respect to the ground.

L-angle Angle over which the label is rotated in the vertical plane. When L-angle is 90

degrees the label is ‘looking’ parallel to the ground. When L-angle is 0 degrees the label ‘looks’ straight up.

P61 firmware

1 INTRODUCTION

The P61 firmware is the standard TRANS-IT® (PS-270) firmware. The TRANS-IT® is based on proven microwave technology in the 2.45 GHz ISM band and allows identification of tags at a distance up to 10 meters, even at high speeding passage. The P61 firmware combines microwave identification with inductive identification at 120 kHz.

The P61 firmware supports a wide range of transponders for various applications. The heavy duty tag is developed typical for vehicle applications. The window-tags can be mounted easily behind the windshield of a vehicle. The booster-unit is a special window tag, which is able to hold a NEDAP inductive identification card. This card is read by the booster. The combi-booster combines the features of the window-tag with a booster allowing to identify both vehicle and driver.

The P61 firmware supports the DC2/DC4 asynchronous communication protocol. This ASCII based communication protocol supports software handshaking and error checking. Identified transponders are automatically reported to any connected host computer in an event message, therefore no polling is required.

Below the main features of the P61 firmware are summarised:

• Supports DC2/DC4 communication protocol

• Identifies microwave 2.45GHz transponders and (if enabled) inductive 120kHz transponders.

• Decodes NEDAP PM-transponders, NEDAP Combi-Boosters and EM Marin 400x transponders.

P61 firmware

2 DIP SWITCH SETTINGS

The TRANS-IT® (PS-270) has 8 DIP-switches, which are used by the P61 firmware as described in the table below. Refer to appendix A when locating the DIP-switches.

VALUE 8 7 6 5 4 3 2 1

Data format 7/even/1 x x x x x ON x x Data format 8/none/1 x x x x x OFF x x

Table 1: DIP-switch settings

Note1: Set DIP-switch 8 only to OFF when using a TRANS-IT® reader with an inductive (120kHz) antenna connected.

The P61 firmware then tries to identify transponders on both antennas (microwave and inductive). When on one antenna a valid transponder is identified it sticks to that antenna source and does not identify anymore on the other antenna. So, when a vehicle is identified with the microwave antenna and this vehicle stays in front of the TRANS-IT®, nobody is identified at the inductive antenna.

When identifying vehicles at high speed it is recommended to keep DIP-switch 8 in ON position.

Note2: Set DIP-switch 7 to OFF when no combi-booster or EF-coded transponders are to be identified. This

increases the detection speed. DIP-switch 7 is only read during a startup.

Note3: Set DIP-switch 6 to OFF when manchester encoded transponders (e.g. EM Marin 400x) are to be identified.

3 LED INDICATORS

A number of LED's are used by the P61 firmware to indicate the current status. The table below describes the function of each LED. Refer to appendix A when locating the LED's.

LED Description

STS Status LED.

Indicates that the power is on and the processor is running. The LED continuously blinks like the system's heartbeat.

ID Identification LED.

This green LED starts to blink fast when a valid transponder is identified. The LED stays off when no (valid) transponder is identified.

UL Unlock LED.

The unlock LED is normally off and goes on when a valid transponder is identified. The

LED is turned off when no transponder is identified anymore and the relay-hold-time

has elapsed. This LED can be connected to a Reflex or DC130 antenna. There is also a relay contact present which has the same function.

NA Lock LED.

Red LED indicating system standby. This LED is normally on and goes off when the

unlock LED goes on. This LED can be connected to a Reflex of DC130 antenna. INP / DOOR

Table 2: LED indicators

Input status LED

This red LED is on when the input contact is closed. The input is not used in the P61

firmware.

4 APPLICATION INFORMATION

The main function of the reader is to detect NEDAP transponders and to transmit its identification number to a host computer. The id-number will be sent to the host in a so-called event message. A detailed description of each event message is given in chapter 4.1.1. Command messages allow a host computer to change settings in the reader or to request information from the reader. The command messages are described in chapter 4.1.2.

4.1 DC2/DC4 PROTOCOL

DC2/DC4 protocol is the standard Nedap protocol which supports two-way communications, error checking and software handshaking. This chapter describes the application layer of the DC2/DC4 protocol as it is implemented in the P61 firmware. Refer to appendix C for a description of the DC2/DC4 protocol details.

4.1.1 EVENT MESSAGES

Event messages are messages that report to the host computer that a specific event has occurred inside the reader. There are different types of event messages that may be send by the reader, like the detection event that is sent when a transponder is identified.

Event messages, when they occur, are stored locally in the reader in the event buffer. Once communication is idle the reader will try to transmit the event message. A maximum of 3 event messages can be stored. When the event buffer is full a new event will overwrite the oldest one. The event buffer is located in RAM memory and its contents will be lost when the power is off.

The reader may send the following event messages. Protocol dependant characters are not shown here. Spaces are added for clarity.

Spaces are only added for readability.

O-event: Reader restarted

Description: The reader sends this event message as soon as the reader is powered-up to

indicate that the system is active. Application settings stored in EEPROM were

not lost. Syntax: 01 01 01 20 O [????????] Where: [????????] Optional unused timestamp. Can be enabled with command

message 0265.

Notes: In case the P-event is sent the O-event is omitted.

P-event: Reader reset

Description: The reader sends this event message as soon as the reader is powered-up to

indicate that the system is active. Application settings stored in EEPROM were

reset to their factory default. EEPROM settings are not lost when the reader is

switched off. The EEPROM settings may be lost when the firmware is changed. Syntax: 01 01 01 20 P [????????] Where: [????????] Optional unused timestamp. Can be enabled with command

message 0265.

Notes: In case the P-event is sent the O-event is omitted.

N-event: Transponder identified (6-digit CF/DF/GF-code)

Description: When a transponder is identified this event message reports its identification

number. This event is only sent when a 6-digit transponder is identified. See also

the timing diagram in Figure 1. Syntax: 01 01 01 20 N [????????] nnnnnn Where: [????????] Optional unused timestamp. Can be enabled with command

message 0265.

transponder card is used.

Notes: When no card is placed in the combi-booster the second identification number is

left blank (filled with zeros).

U-event: Transponder identified (80-bit EF-code)

Description: When a transponder is identified this event message reports its identification

number. This event is only sent when an 80-bit transponder is identified. Syntax: 01 01 01 20 U [????????] xxxxxxxxxxxxxxxxxxxx Where: [????????] Optional unused timestamp. Can be enabled with command

message 0265.

xxx...xxx Identification number 80 bit hexadecimal.

x Hexadecimal character made out of 4 bits (nibble) added with the

value of character '0'.
