Phase Matrix warrants its products to be free from defects in material and workmanship for one year from the date of delivery. Damage due to accident, abuse, or improper signal level is not covered by the warranty. Removal, defacement, or alteration of any serial number, inspection label, marking or seal may void the warranty. Phase Matrix will repair or replace, at its option, any components of this product that prove to be defective during the warranty period provided that the entire unit is returned freight prepaid to Phase Matrix, Inc. or an authorized service facility. In-warranty units will be returned freight prepaid; out-of-warranty units will be returned freight COLLECT. No warranty other than the above is expressed or implied.
The LI-62XX series of analyzers has a serial port for digital communications and LabVIEW can be used to read the serial port. The serial port settings on the 62XX instrument should be set using keypad FCT17. The variables that have to be measured can be set by sending the *13x,x,x,x,x,x,x,x,x,x, where x is the channels you want to output. By writing *12 to the serial port along with a carriage return (serial write block), the data will be sent out and it can be read by using the serial read block. Writing and reading of the instrument data can be done in a simple while loop. The instrument is polled for data and it can be read continuously at a rate set by a LabVIEW timer. In the example below, channels 22, 23 29, 32, 33, 38, 39, 42 and 43 are configured to be sent out through the serial port. The serial setting property node is used to estimate the number of bytes at the port and then this information is fed to the serial read block to read in the data. To parse out and plot the data, search and replace vi and spread sheet string to array vi are used.
Parity is a simple way to error-check. There are Even, Odd, Mark and Space indicators. You can also use no parity. For Even and Odd parity, the serial port sets the parity bit (the last bit after the data bit) to a value to ensure that the data packet has an Even or Odd number of logic-high bits. For example, if the data is 10010010, for Even parity, the serial port sets the parity bit as 1 to keep the number of logic-high bits Even. For Odd parity, the parity bit is 0 so that the number of logic-high bits is Odd. Mark parity simply sets the parity bit to logic-high and Space sets the parity bit to logic-low, so that the receiving party can determine if the data is corrupted.
The basis of 1-Wire® technology is a serial protocol using a single data line plus ground reference for communication. A 1-Wire master initiates and controls the communication with one or more 1-Wire slave devices on the 1-Wire bus (Figure 1). Each 1-Wire slave device has a unique, unalterable, factory-programmed, 64-bit identification number (ID), which serves as device address on the 1-Wire bus. The 8-bit family code, a subset of the 64-bit ID, identifies the device type and functionality. Typically, 1-Wire slave devices operate over the following four voltage ranges:
1-Wire technology is based on a serial communication protocol that uses a single data line plus ground reference between the master and slave. The 1-Wire slaves are available in plastic packages as bumped die or stainless-steel iButton form. The minimum function of 1-Wire slaves is a 64-bit ID number. Additional functions are PIO, temperature sensor, time counter, NV SRAM, OTP EPROM, EEPROM, SHA-256/SHA-3/ECDSA engine, SHA-256/SHA-3/ECDSA secure EEPROM, temperature logging and humidity logging. Typical applications for 1-Wire devices include identification and authentication of consumables, rack cards, PCBs, computer accessories, and the protection of IP (e.g., cloning prevention). Special uses of iButton devices are access control, asset management, guard tour systems, time and attendance, electronic cash, and temperature monitoring for food and pharmaceutical safety. Starter EV kits and software drivers are available to assist customers integrating 1-Wire technology in their systems.
LabVIEW 2010 also uses customer feedback to deliver new features that make getting started easier. For example, LabVIEW now provides a new hardware configuration tool that makes it possible for users to access and configure their LabVIEW Real-Time targets remotely via a Web browser. Other features include a smart installer that automatically detects the software associated with a serial number for faster installation and an improved instrument driver finder that offers prebuilt project examples for specific instruments.
The Lab Brick signal generators include a green LED status indicator to show connection to a USB host computer. When the host computer recognizes a Lab Brick signal generator, it loads the GUI software and displays that signal generator's serial number and model number. The GUI software can track and control several connected Lab Brick signal generators, simplifying multiple-signal test setups. In addition, each Lab Brick signal generator can store settings in internal memory, allowing it to power up in a specific instrument state. This same capability also allows a Lab Brick signal generator to be used in an embedded or remote instrument application without USB control required to achieve a given instrument state. In non-USB applications, the Lab Brick signal generators can operate with battery power or remote power supply. For automatic-test-equipment (ATE) applications, a programming guide is available for each Lab Brick signal generator. In addition, they are programmable by means of LabView software drivers from National Instruments (www.ni.com). 2b1af7f3a8
