操作原理：
d5000 modules are complete four-channel data acquisition systems.each unit contains analog signal conditioning circuits optimizedfor a specific input type. the amplified sensor signals areconverted to digital data with a microprocessor-controlledintegrating a/d converter. offset and gain errors in the analogcircuitry are continuously monitored and corrected usingmicroprocessor techniques. the d5000 converts the digital signaldata into engineering units using look-up tables. the resultantdata is stored in ascii format in a memory buffer. the modulescontinuously convert data at the rate of 8 conversions per secondand store the latest result in the buffer.
the host computer may request data by sending simple ascii commandsto the module.
digital filter
the d5000 options include a unique programmable single pole digitalfilter. the filter is used to smooth analog data in noisyenvironments. separate time constants may be specified for smalland large signal changes. typically, a large time constant isspecified for small signal changes to filter out noise and providestable output readings. a smaller time constant may be chosen forlarge signal changes to provide fast response to suchchanges.
communications
the d5000 are designed to be easy to interface to all popularcomputers and terminals. all communications to and from the moduleare performed with printable ascii the d5000 will instantly respondby communicating the ascii buffer data back to the host.
user options
the d5000 offers a variety of userselectable options includingchoice of address, baud rate, parity, echo, etc. all options areselectable using simple commands over the communications port. alloptions are stored in a nonvolatile eeprom which maintains dataeven after power is removed.
communications the d5000 are designed to be easy to interface toall popular computers and terminals. all communications to and fromthe module are performed with printable ascii characters. thisallows the information to be processed with string functions commonto most high-level languages such as basic. for computers thatsupport standard ports such as rs-232c, no special machine languagesoftware drivers are necessary for operation.
rs-232c is not designed to be used as a multiparty system; however,the module can be daisychained to allow many modules to beconnected to a single communications port. in this network, anycharacters transmitted by the host are received by each module inthe chain and passed on to the next module until the information isechoed back to the host. if a module is correctly addressed andreceives a valid command, it transmits a response on the daisychain network. the response will be rippled through any othermodules in the chain until it reaches the host. rs-485 wasdeveloped for multidropped systems that can communicate at highdata rates over long distances. for systems requiring many modules,high speed or long distances, rs-485 is recommended.
