I. WHA T SIGNAL CONDITIONERS DO: The DRX Series Signal Conditioners are high performance devices used as a front end for PLC’s and Data Acquisition systems to measur e a variety of low level transducer signals with high precision and accuracy . The DRX Series Signal Conditioners interface directly to transducers and digitize the input signal. The[...]

For Procomm : Start the Procomm Program. Press AL T + P (Select the appropriate communication parameters: Baud Rate, Parity , Data Bits, Stop Bits.) The default settings may require modifications. - Factory Default communication settings are as follows: Baud Rate = 9600 Parity = Odd Data Bits = 7 Stop Bits = 1 Press AL T + S (T o save current commu[...]

Communication Parameter Settings: Communication settings information are very critical during set-up, if any of the parameters are changed, it should be recorded on the label for futur e reference. If the communication parameters used by the computer does not match the communication parameter of the DRX, then the communication link may not be estab[...]

Page 4 SAFETY CONSIDERA TIONS Unpacking & Inspection Unpack the instrument and inspect for obvious shipping damage. Do not attempt to operate the unit if damage is found. For instruments with AC V oltage and AC Current inputs, observe the input signal connections in the appropriate section of this manual. These instruments must only be installe[...]

SAFETY NOTE: Disconnect all signal input and outputs before attempting this procedure. Instructions 1) Open the Signal Conditioner Unit—Remove Side Covers from Unit by lifting at the “angled corners” first, using a flat-head screwdriver . Continue detaching remaining edges of the Cover . 2) Short TP6 & TP17 together , either by wire or , [...]
