<br />. <br /> <br />sensors. The microprocessor provides for programmable input of data measure- <br />ment and transmission scheduling, data manipulation, and data storage. The . <br />DCP is programmable by utilizing a portable terminal via an RS-232 port. The <br />DCP measures approx imate ly 1 DIX8Ix4". The shaft encoder converts incremental <br />stage values from analog to digital in hundredth of a foot intervals. The . <br />shaft encoder communicates directly with the DCP. The unit measures approxi- <br />mately 8Ix6Ix6". The NEMA enclosure houses the DCP and the battery. The un it <br />measures approximately 24Ix20IxlO". . <br /> <br />The transmission receive hardware basically consists of a 5-meter para- <br />bolic dish, downconverter, receiver, amplifier, multiplexor, and eight fre- . <br />quency agile programmable demodulators. This Direct Readout Ground Station is <br />located at the Centennial Building, the Office of the State Engineer. <br /> <br />. <br /> <br />The central computer is comprised of a DEC VAX 11/750 computer with two <br />456 MByte hard disks, two 9-track tape drives (100 ips streamer mode 25 ips), <br />four multifunction communications boards with eight serial ports each, and 32 . <br />modems. The VAX utilizes the VMS operating system. The system is designed to <br />handle in excess of 300 DCP's. The central computer is located in the Centen- <br />nial Building at the Office of the State Engineer. tk <br /> <br />The software, HYDROMET, was developed by the system contractor, Sutron <br />Corporation. It is comprised of real-time data processing and archiving .. <br />programs, alert/warn ing programs, reports and graphi cs output programs, and <br />system performance monitoring programs. The software is written in Fortran. <br /> <br />. <br /> <br />-4- <br /> <br />. <br />
