OS/T Network Communication & Control unit
The Network Communication & Control unit (NCC4) in the OS/T has several functions:
• Supplying the 33V DC power supply for all the units in the system. On 1 NCC4 it’s possible to
connect up to 16 receiver (NR4) or transmitters (NT4) units.
• Generating the HF sync signal for the whole system. This HF signal has a frequency of four times
8.2 MHz and sweeps between 30.... 36 MHz. One NCC4 has four outputs and on each output you
can connect a NR4, NT4 or an other NCC4.
• The NCC4 is data-com master for all connected units. All data-communication between the
connected units and the NCC4 will be initiated from the NCC4. With the external sync input from the
NCC4 it’s possible to integrate the NCC4 in a larger network with multiple NCC4's.
• Each NCC4 has a RS 232 communication connector from which it’s possible to connect to the
outside world, for example to a modem or to a PC. With this connection several things can be done,
such as remote-diagnostics and firmware-upgrades.
Figure 1 shows the block diagram of the OS/T NCC4.

Description of the NCC4:
DC power supply
The 33 Volt DC Power voltage from the OS/T system is generated in a Switched-mode power unit,
which is connected with a short cable on connector K5. The power supply has a continuous DC output
current rating of 3.2 A.
HF
The HF signal is generated in a VCO. This VCO uses for its frequency control the 3 signals from the
local DSP: TD, in advance of the start pulse and T1 and T2 on 345 and 1334 s after the start pulse.
The signals T1 and T2 mark the time that the frequency of the NT4 passes the 7.7 and 8.7 MHz. A
saw-tooth generator generates the waveform, necessary to sweep the VCO. The saw-tooth generator
exists of a capacitor, charged with a constant current and is discharged at every pulse.
Regulation of the VCO happens only in the fly-back period to get the highest possible signal purity. By
using a buffer stage the HF-signal gets the requested level and will be merged with the data-com
signal. Then this signal is distributed to four output connectors K1 till K4.
Data-com
One of the important features from the OS/T system is the data-com over the coax-cable. With this
feature it’s no longer necessary to use an extra data-cable between the units, which simplify the
installation of the system. The NCC4 plays a central roll in providing the data-com. All the connected
units are interrogated periodically by the NCC4. If there are messages like an alarm on a connected
NR4, then the NCC4 will be process this and takes the necessary action: Sending a command, to turn
on the lamps on the activated aisle.
At the beginning of each sweep, on a fixed timeslot, the NCC4 sends a data-block. This data-block
may contain a question for a connected NR4 or NT4. The answer will be transmitted in another timeslot.
The transmission of data is accomplished by adding small pulses on the HF signal. With a low pass
filter and a sensitive amplifier these pulses can be recovered on the receiving side..
If multiple NCC4's are necessary to be fitted in a larger installation, then they have to be linked. Every
NCC4 is then a master for his own segment. The “upper neighbour” of a NCC4 is connected to a slave
sync input, while the “under neighbour” in the circuit will be connected on an output. The slave sync
input is doubled to link the incoming cable to the next segment of the “upper neighbour”. When the
NCC4 is the last one in a chain a terminator jumper must be placed.
A slave NCC4 may be switched off without disturbing the data communication.
RS 232 interface
Each NCC4 is equipped with a RS232 connector. With this it’s possible to connect a modem or a PC
to communicate with the OS/T system.
With these capabilities you can use remote-diagnostics, firmware-upgrade and system configuration.
The communication uses the standard UART circuit.
I/O connector
The NCC4 comes with an I/O connector with four opto-coupler inputs, four opto-coupler outputs and
four relay outputs with one voltage free make-and-break contact. All in- and outputs are galvanic
separated from the power supply. The in- and outputs may be used for camera activation, metal
detection alarm, extra alarm-lamps. The functionality of the in- and outputs is determined by the
software.
Hand-terminal connector
A standard NEDAP RS Handheld terminal may be connected to the NCC4. With these HT you can
edit the various local settings.
