TDC PCB
The TDC PCB is will be used to detect, deactivate and count 8.32MHz labels and tags.
When detecting a label the TDC will try to blow it. After a successful blow up, the
deactivation will be counted.
Is it not possible to deactivate the label, it will be counted as a FTD (Failure To
Deactivate)
The TDC distinguishes between hard- and paper tags
Selectable and distinguishable audio alert for:
- Hard tag detected
- Paper tag detected
- Paper tag deactivated
- Paper tag not deactivatable
The TDC bursts only when paper tags are within detection range (generating minimum
electro smog)
The channels
The TDC has two independent channels. To each of these channels can be connected an:
- Add-On antenna
- TDC-DUC.
Stand alone - Master - Slave
There are three possible configurations for the TDC
- Stand alone
- Master
- Slave
Count function
The TDC has the possibilities of:
- Counting deactivations
- Counting detections
- Counting “Failure To Deactivate” (FTD’s)
- Collecting label data (Q-factor).
All this data can be viewed in EASi/Net or in the OS/T Builder.
Upgrading the TDC
It is possible to upgrade TDC. This is done with so called Functionality Modules. The
module contains several settings which enable some functions of the TDC. Upgrading the
TDC is possible with a combination of the EASi/Net and a handheldterminal and in the
future also by using the OS/T Builder.
Firmware
To communicate with a TDC, firmware version 1.602 or higher must be installed.
1. OS/T TDC: Introduction
5
TDC 2004 V1.20 | Nedap Retail Support
Generally the TDC is in great lines the same as the earlier Nedap deactivators like the
DRF2B.
The antenna gets a weak detection-field with a frequency sweep of 7.8 to 8.6 MHz. With
a receiver it is possible to detect EAS labels. If the receiver detects a label which matches
the adjusted criteria, the deactivator switches a burst power output which generates a
very strong RF burst signal exactly at the resonance frequency of the detected label.
One or several short bursts (circa 30uS) of high power (up to 1KW) will deactivate the
label.
After the burst, the receiver checks if the label is successfully deactivated.
This behavior is different then the previous Nedap deactivators. The previous types kept
on bursting until the label was no longer detected. The TDC doesn’t do this. At a
successful deactivation a counter will be raised which counts the total amount of
successful deactivations. If deactivation fails, an other counter will be raised which
counts the failed deactivations. Only when the label is taken out of the detection field and
will be placed back in this field a second attempt will take place. The countermeasures
can be read by the OS/T network.
The TDC has also some extra functions:
- External In- and outputs
- Data-communication via RS232 and OS/T network
- Possibility to work as a master in an OS/T system
These functions are optional. They can be installed in a TDC as an Functionality Module
using the CRA protocol.
Block scheme
The hart of the TDC is the DSP which controls the TDC. In the DSP the signals TD, T1 and
T2 are generated who control the 32MHz VCO. The 32MHz VCO creates the OS/T sweep
signal.
After being split in four, the detection field transmit signal is generated. This signal will
be amplified and via the directional coupler supplied to the RX/TX mux.
2. How the TDC works
6
TDC 2004 V1.20 | Nedap Retail Support
As long as that there are no bursts generated the RX/TX mux sends the signal to the
antenna mux. This mux will choose the correct antenna or when both channels are used
the signal will be switched at each sweep (multiplexing) like other OS/T units.
The received label signal goes the other way around through the both mux’s and ends at
the directional coupler. The TX signal will send to the receiver-mixer. The directional
coupler will take care of the fact that there will be as less as possible transmitter-signal
directly into the receiver input.
After filtering, mixing and amplifying the signal comes at the AD converter. The signal
will now be processed in the DSP.
When the DSP recognizes a label, a burst will be fired. To do this, the wanted burst-
power (100, 400 or 1000 watt) must be switched at the beginning of the sweep period.
Also the RX/TX mux must be changed to connect the burst-power output with the
antenna mux. The DSP selects the correct antenna, the same as where the label was
detected.
At this moment will be waited until the present frequency of the sweep meets the
resonance frequency of the detected label. At that moment the final burst-pulse will be
generated which switches the burst power output. The burst length is adjustable between
5 and 60uS via the TDC menu (OS/T Builder or Handheldterminal). Also an adjustable
amount (0,1 or 2) of repeating bursts can be set for a reliable deactivation.
De deactivator also measures the Q of the label and stores this data. Via the OS/T
network, statistic data is available about the quality of the labels.
An on-board buzzer will generate an acoustic signal. By using the handheld terminal or
OS/T Builder it is possible to program how and when the signal will take place.
It is also possible to use an acoustic signal at the antennae. To do so a voltage will be
put on the coax cable to the antenna. This signal is also adjustable in the handheld
terminal or OS/T Builder.
Like other OS/T products it is possible to connect external in- and outputs like for
example a keyswitch, I²C I/O board or a counting detacher.
Datacom
The TDC datacom knows 3 configurations, Stand-alone, Slave and Master.
Stand-Alone (Menu datacom=0)
In the stand-alone configuration is no network communication possible. Only by using
the RS232 communication is possible.
Synchronization with other units is not possible. This situation will be used for a stand-
alone deactivator at a great distance (>10meters) from an EAS system or other
deactivators.
Slave (Menu datacom=1)
In the slave configuration the TDC will behave as a normal OS/T slave. Via the slave-sync
input the TDC can be put into a network. The network will take care of the
datacommunication and synchronization. The 33Volt Dc power can be obtained via this
input. In the slave mode the internal sweep-generator has an interleave of 5 to the
supplied sync. signal.
The use of the master-output is not possible in slave-mode. When there will be no
sync/datacom supplied, the slave will automatically behave as a Stand-alone unit.
Master (Menu datacom=2)
In the Master mode the TDC behaves as a NCC. The internal sweep generator has an
interleave of 1 to the supplied sync. To the master-output several slave units can be
connected, like an IQE-unit.
