To maximize efficiency, the sunlight needs to be accurately focused. Being off by even a single degree could result in a significant drop in efficiency, and the biggest impact to the cost of delivering solar energy is efficiency. As with most systems, the accuracy is limited by the accuracy of the sensors used in that system. There are a number of different types of sensors that can be used in these systems. This paper discusses why an absolute inclinometer is the most effective sensor solution and why the US Digital T7 is superior to other inclinometers available today. Download the document here .

QSB Commands List.pdf   (454KB) User GuidesTue, 08 Dec 2009 13:53:00 PST http://usdigital.com/support/user-guides/ad4b-communications-protocol The AD4B adapter provides a simple plug in method for connecting a single ended or differential quadrature encoder directly to an RS-232 serial com port. One end of the AD4 plugs into a serial port, while the other end plugs into a quadrature encoder. A quadrature counter ( LFLS7166 ) inside the AD4 keeps track of encoder position, while a microprocessor provides a serial interface for the user to query the counter for the encoder position. The bidirectional data lines carry commands from the host computer and responses from the AD4B . The format is 1 start bit, 8 data bits and 1 stop bit. The baud rate can be changed, but it always starts as 9600 baud after reset or power-up. Large numbers are transmitted with the most significant byte first. AD4 Serial Commands: Ping: Function: Test for the presence of an AD4. Send 1 byte: 'A' (41 hex) Returns 1 byte: '4' (34 hex) Read Position: Function: Latches the counter and returns the current position. Send 1 byte: 01 hex Returns 4 bytes: 4 byte current position, LSB first. The LFLS7166 is a 24-bit counter, the 4th position byte can be ignored. Initialize AD4's counter: Function: Initializes the LFLS7166, sets the quadrature to a specified multiplier, and loads the preset register with a specified value. Initialization data sent to the LFLS7166's registers: 68 hex, B0 hex, C0-3 hex ( see LFLS7166 web page ). Send 6 bytes: 22 hex, quadrature mode (0, 1, 2, 4), 4-byte preset register value Returns 1 byte: Checksum Read the Counter's Output Data Register: Function: Reads a byte directly from the LFLS7166's output latch(OL) ( see LFLS7166 web page ). Send 1 byte: 33 hex Returns 1 byte: Value of LFLS7166's OL, the OL consists of three bytes auto-incremented by each read, LSB first. Write to Counter's Input Data Register: Function: Writes a byte directly to the LFLS7166's preset register(PR), the PR consists of three bytes auto-incremented by each write, LSB first ( see LFLS7166 web page ). Send 2 bytes: 44 hex, 1-byte data Returns nothing. Read the Output Status Register: Function: Reads the LFLS7166's output status register(OSR) ( see LFLS7166 web page ). Send 1 byte: 55 hex Returns 1 byte: Value of LFLS7166's OSR. Write to the Counter Control Register: Function: Writes a byte directly to one of the LFLS7166's control registers. Bits 6 and 7 select which control register to write to ( see LFLS7166 web page ). Send 2 bytes: 66 hex, 1-byte register value Returns nothing. Change Baudrate: Function: The baudrate change will be effective after checksum is sent by the AD4. The baudrate always defaults to 9600 after a reset or power-up. Send 2 bytes: 77 hex, Baudrate Code (See table below) Returns 1 byte: Checksum Baud Rate Byte 0x00 0x01 0x10 0x11 0x12 0x13 0x14 0x15 Baud Rate 115200 57600 38400 19200 9600 4800 2400 1200 Enable Index: Function: Enables the Index. The counter will reset when index=true. Send 1 byte: 88 hex Returns 1 byte: 'E' (45 hex) Disable Index: Function: Disables the Index. Send 1 byte: 99 hex Returns 1 byte: 'D' (44 hex) User GuidesWed, 28 Oct 2009 15:29:00 PDT http://usdigital.com/support/assembly/press-on-hub-disk-removal Assembly InstructionsMon, 15 Jun 2009 12:29:00 PDT http://usdigital.com/support/selector-guides/absolute-encoder-selector-guide "Absolute output" - no need for re-zeroing after power cycling.
