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. Fig.1 © Nedap Retail Support 2004 – Groenlo Holland NCC4 2.10 10.5.2004 GO 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. © Nedap Retail Support 2004 – Groenlo Holland NCC4 2.10 10.5.2004 GO Figure 2 shows the component arrangement of the NCC4 (Hardware version 4): The following points can be used K100 K101 K102 K1 K2 K3 K4 K5 K6 K7 K8 K9 slave sync input slave sync input 50 ohm terminator Output Output Output Output 32V DC power input power LED connection 50 ohm terminator in aid of K1 50 ohm terminator in aid of K2 50 ohm terminator in aid of K3 K10 K11 K202 K203 K205 K206 K207 K208 K209 C12 50 ohm terminator in aid of K4 50 ohm terminator in aid of K202 RS 485 interface connector RS 232 interface connector Hand-terminal connection Relay outputs Ry3, Ry4 Relay outputs Ry1, Ry2 Opto outputs 1-4 Opto inputs 1-4 VCO linearity Indicator leds ( Y = yellow, Rd = red, Gr = green) D27 Power (Gr) D220 NCC4 (Y) (On= a tag is detected by the NR4) D221 NCC4 comm fault (Rd) (On= a segment doesn’t answer) D2 Sweep lock(Y) D3 Center lock(Y) Testpoints Tp6 Tp7 Tp8 Tp9 Tp15 Tp16 Tp14 Sweep voltage Master Tx Master Rx Master Clk Slave Clk Slave HF in Slave HF 32MHz © Nedap Retail Support 2004 – Groenlo Holland Tp11 Tp12 Tp13 Tp20 Tp21 Tp22 Slave Tx Slave Rx Slave Start T2 T1 TD NCC4 2.10 10.5.2004 GO Specifications Mains NCC4: Power Supply Power Consumption 230 Volt 50 Hz Max 150 Watt NCC4-pcb: Power supply Current consumption Sync input signal Outputs (4x) Frequency sweep Sweep frequency Maximal DC load to one or more outputs Maximal DC load to one or more outputs 33 Volt DC 100 mA (excl connected slave units) 30-36 MHz, minimal 4 dB in 50 ohm (1Vtt) 30-36 MHz, nominal 10 dB in 50 ohm (2Vtt) 1400 kHz 600 Hz saw tooth form. 3.2 A (ca 16 slave units)at 230 V 2.0 A (ca 10 slave units)at 115 V © Nedap Retail Support 2004 – Groenlo Holland (90-220 Volt 50-60 Hz) NCC4 2.10 10.5.2004 GO Revison-view: Hardware version 5: Nr Index Date april 2000 Description Perform - Jumper K11 removed and K202 became a feature connector. - Jumper K102 moved a little. - Components are removed / changed. © Nedap Retail Support 2004 – Groenlo Holland Nedap NCC4 2.10 10.5.2004 GO
