<br />. <br /> <br />. <br /> <br />. <br /> <br />OOJ102 <br /> <br />Sierra/Misco's advanced design of the data decoder achieves a new standard <br />for data discrimination A microprocessor on board the 50510 checks <br />incoming radio traffic for valid data If a valia message is received the <br />message is passed on to the base station computer If not the message is <br />ignored <br /> <br />In a noisy radio environment as much 99 percent of the total radio traffic <br />can be noise. The 5051D prevents noise from burdening the base station <br />computer Less computer time is spent handling noise and more time is <br />available to service the analytical needs of real data Base station <br />efficiency is dramatically increased during crucial periods of heavy usage <br /> <br />Selective processing of incoming data messages is also available with the <br />50510 selected sensor nutnbers can be preprogramed into the decoder Only <br />those data messages containing valid identification numbers will be allowed <br />to pass on to the base station computer Selective processing is used to <br />further tighten the quality control of incoming data <br /> <br />Only Sierra/Mis co decoders have these vital features <br /> <br />Model 5051R/D Specifications <br />RECEIVER <br />F'requency range <br />Sensitivity <br /> <br />Frequency stability <br />Modulation Acceptanc~ <br />Power required <br /> <br />135 174 MHZ <br />o 25 microvolts min.

Quality control checks are performed as the data arrives, Valid <br />reports are automatically stored in the computer data base <br /> <br />Data can be displayed in a wide variety of formats Graphical and tabular <br />reports can be created Reports can be diverted to printers or plotters for <br />paper copy, Other users can access the data base through optional video <br />
