Rev B4, Page 2/6 DESCRIPTION Hardware All pins on ic-nq are lead out as terminals. Supply voltages VDDA (analog) and VDD (digital) as well as GNDA and GND are linked but can be separated if needed by removing jumpers J6 and J7. A 5 V series regulator can be assembled as an option for external voltage supply via pin VB. 8-pole sockets are provided for the input wiring of SIN, COS and ZERO. Individual components or a complete second board connecting sensors can be clipped onto these. An RS422 driver (type 75179) can be used for data transmission via BiSS with an RL/CL line termination. The interface cable is connected to the sub-d 9 pin. Resistors RSCL and RSDA are not required if the EEPROM is to be accessed solely via ic-nq.

Rev B4, Page 3/6 Software Control software nq_xx.exe with its parameter file default.hex runs on a PC under Windows. A driver for the parallel interface is also required and assembled. The self-extracting file port95nt.exe installs all the necessary files. BIOS Setup Bi-Directional or EPP (eg. under Win NT) must be selected in the BIOS for the bidirectional operation of the parallel interface. Setting the BIOS to Normal alone is not sufficient. Typical DMA settings are: ECP DMA select 3, on-board parallel interface address 378h with interrupt Q7. Software Description Fig. 3: Screen display.

Rev B4, Page 5/6 Operation with BiSS PC Adapter IC103 BiSS PC adapter IC103 is provided for communication via BiSS without a master IC. Using this adapter ic-nq's control program can emulate BiSS line signals via the parallel interface. Required assembly for NQ1D: jumper J4, connection of pins 2 with 8 and 3 with 5 at socket U3 or line driver U3 75179, no linear regulators X1/X2. The adapter is powered via jumper J4 from board NQ1D which itself should be powered by +4.75 V connected to ground at VDD (the current draw is ca. 25 ma with the adapter). BiSS Master Emulation should be selected as the mode of operation here; the necessary master and slave parameters are preset. BiSS emulation is slow with long timeouts; the EEPROM is suitably preconfigured to this end (default delivery status). As the BiSS protocol is controlled via timeout parameters and data in register mode is transmitted using PWM, each interrupt can result in a faulty data transmission on a multitasking operating system. It is thus recommended that no other programs be run simultaneously. Fig. 4: Adapter IC103 Operation with BiSS PC adapter MB3A The ic-nq control program supports the use of BiSS PC adapter MB3A which is either clipped directly onto the board NQ1D or connected by leads. Board NQ1D powers the adapter and must be supplied with +5 V at VDD versus GND. Required assembly for NQ1D: jumper J4, line driver U3 75179, linear regulators X1/X2 optional. Adapter MB3A operates with BiSS master ic-mb3, activated by the control program via an SPI link. The mode of operation should thus be set to BiSS Master SPI Mode. Various timeout parameters are possible, as are sensor data transmissions at a rate of up to 10 Mbit/s. Operation with BiSS Master Board MB3D-S The ic-nq control program supports the use of BiSS master board MB3D-S which is either clipped directly onto the board NQ1D or connected by leads. Here, the master powers the sensors, with board MB3D now supplying board NQ1D with power. To this end, master board MB3D must be supplied with +8 V at VB versus GND. Fig. 5: Adapter MB3A Required assembly for NQ1D: jumper J4, line driver U3 75179, no linear regulators X1/X2. Board MB3D-S operates with BiSS master ic-mb3, activated by the control program via an SPI link. The mode of operation should thus be set to BiSS Master SPI Mode. Various timeout parameters are possible, as are sensor data transmissions at a rate of up to 10 Mbit/s. Fig. 6: BiSS master MB3D-S
Rev B4, Page 6/6 Operation with BiSS Master FPGA Board SY1D (MB1D) The ic-nq control program supports the use of BiSS master FPGA board SY1D which is either clipped directly onto the board NQ1D (after removing the connecting nuts on one side) or connected by leads. Here, the master powers the sensors, with board SY1D now supplying board NQ1D with power. To this end, master FPGA board SY1D must be supplied with +8 V at VB versus GND. Required assembly for NQ1D: jumper J4, line driver U3 75179, no linear regulators X1/X2. Jumper J3 on SY1D selects either BiSS Master Intel Mode or BiSS Master Motorola Mode (default delivery status); the operating mode of the software should be set accordingly. Various timeout parameters are possible, as are sensor data transmissions at a rate of up to 10 Mbit/s. Fig. 7: BiSS master SY1D Communication Failures For adapter IC103: If error message "Error TimeOut: NO SL ACK" is generated on "Initialize", the BiSS signals on line MA on NQ1D should be checked. If no reaction to "Initialize" is forthcoming here, it is then necessary to check the configuration of the PC parallel interface.
