ii NOTES.
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.
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.
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.
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.
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 .
IV . COMMANDS FOR ACCESSING EEPROM: NO. command letter index meaning # of bytes 1. R,W 01 Input range or function 1 2. R,W 02 Input/output Configuration 1 3. R,W 03 Decimal point 1 4. R,W 04 Filter time constant 1 5. R,W 05 Reading scale 3 6. R,W 06 Reading offset 3 7.
2. If unit is not in echo mode : i. For the commands which require the data to be transmitted by the DRX Signal Conditioner , data is sent in the following formats: data[hh]<cr> ii. For the commands which do not require the data: NO RESPONSE B. Error response: 1.
?ee : Special code indicating an error has occurred as: ?43 : Command error ( occurs if command letters and indexes are invalid) ?46 : Format error ( occurs if length of the data or number of characte.

Note 1: Bit 2&3 set the speed of pr ocess totalize. The time it would take process totalize to reach the non-totalize reading is shown in the following table: Bit 3 Bit 2 T ime to reach regular reading 0 0 1 minute 0 1 1 hour 1 0 1 day 1 1 30 day 3.
5. READING SCALE: Multiplication factor applied to input to get a higher or lower reading. This is 3 byte data (6 characters) as follows: - Bits 0 to 18 (19 bits) are value of the scale from 0 to 5000.
P ARITY = bits 4,3 and are: 00 for NO 01 for ODD 10 for EVEN 1 1 not used DA T A BIT = bit 5 and is: 0 for 7 data 1 for 8 data STOP BIT = bit 6 and is: 0 for 1 stop 1 for 2 stop Bit 7 : always 0 Note 1: Stop bit is always 1. Unless 7 data, no parity is selected then unit will use 2 stop bits.
9. DA T A FORMA T : This is one byte and specifies the data which will be transmitted against the "V01" command. Bit pattern: bit 0 = 0/1 Means do not include/include peak & valley status register . bit 1 = 0/1 Means do not include/include reading.
12. UNIT OF MEASURE: This is 3 bytes. It is ASCII value of unit of measur e. 13. GA TE TIME(For FP model only): This is 1 byte from 00 to FF . For value = 00 to F A: Each count equals 10ms. If 0 then gate time = 3ms. Example : 1 second gate time = 64 hex.
VI. COMMANDS FOR MEASUREMENT V ALUES: Command Receiving value *01X01 (For all models): Reading value . After reading scale and offset. Note: In order to have continuous update on reading. Customer should send X01 command every time reading is requested.
VIII. RESET COMMANDS : *01Z01 (For all models) : Hard reset (r eading data from EEPROM). *01Z02 (For all models) : Soft reset (Initialize reading). *01Z03 (For models: TC/R TD/ACV/ACC): Reset peak and valley . (For models: PR/ST): Reset process totalize value.
