I. WHAT SIGNAL CONDITIONERS DO:
The iDRX Series Signal Conditioners are high performance devices used as a front end for PLC’s and
Data Acquisition systems to measure a variety of low level transducer signals with high precision and
accuracy. The iDRX Series Signal Conditioners interface directly to transducers and digitize the input
signal. The measured signal is then transmitted to a PLC or a computer using the RS485 Serial
Communication. Up to 32 units may be connected to the same serial RS485 bus, and each unit
may be addressed to transmit the signal being measured under program control, executed on a PLC
or a computer. The key features of the iDRX Series Signal Conditioners are the ease of set-up and
factory calibrated ranges. All range switching are done electronically by sending the appropriate
command; therefore, there is no need to remove or open the units when signal input levels are
changed. All set-up may be done by using the Set-up Software running on a computer or by user
supplied programs.
II. MODEL OF UNIT :
There are 7 models available:
THERMOCOUPLE ( iDRX-TC )
RTD ( iDRX-RTD )
STRAIN ( iDRX-ST )
PROCESS ( iDRX-PR )
FREQUENCY/PULSE ( iDRX-FP )
AC VOLT ( iDRX-ACV )
AC CURRENT ( iDRX-ACC )
III. RS485 SERIAL COMMUNICATION SETUP:
Communication with the UNIT will be performed via serial communication using RS485 standard (half
duplex). To use the RS485 communication for the Signal Conditioners you’ll need an available
Communication port in your computer and have access to a generic communication software program
1
(e.g.: Procomm
conditioner communication software program is also available as an option to speed the set-up. A
RS232 to RS485 converter box will also be required if your computer communications port is RS232.

, Windows2HyperTerminal3, etc, see details below for information). A RS485 signal
Page 1
For Procomm:
Start the Procomm Program.
Press ALT + 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 ALT + S (To save current communication settings)
Press ALT + O (To go to chat mode)
If the communication port selected is available and the communication parameters of both the
computer and the iDRX are matched, then a serial link may be established. To check the
communication any of the commands may be tried i.e. *01X01 would return the current
measured signal value.
For Hyper Terminal (Windows 95):
Start the Hyper Terminal Program from programs/accessories.
Click on the Properties from the File menu.
Under the Phone Number Menu choose:
Connect using “Direct to COM1 or COM2” whichever that’s available.
Click on Configure Button.
Choose: Baud rate, Data bits, Parity and Stop bits
According to iDRX’s settings.
Flow Control = None.
Click “OK” Button.
- Factory Default communication settings are as follows:
Baud Rate = 9600
Parity = Odd
Data Bits = 7
Stop Bits = 1
Under Settings Menu:
Click ASCII Setup Button.
Choose all options except “Force Incoming Data to 7 Bits ASCII”.
Click “OK” Button.
Page 2
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 future reference. If the communication parameters
used by the computer does not match the communication parameter of the iDRX, then the
communication link may not be established. Hence it is important to record the communication
parameter on the label if different from default.
Resetting Communication Parameters to Factory Defaults
To restore the communication parameters to the factory default settings, two test points must be
shorted together. There are two ways of shorting these test points together, both are detailed below
and shown in the following figure.
Version A-- Test point TP6 must be shorted, by a wire, to test point TP17.
or
Version B-- Newer units have a jumper position S1-A for connecting these two test points together.
Factory Default Settings for Communication:
Baud Rate = 9600
Data Bit = 7
Parity = Odd
Stop Bits = 1
Recognition Character = *
Address = 01
Page 3
Open the Signal Conditioner Unit
Disconnect all signal input and outputs before attempting this procedure.
Instructions
1) To open the Signal Conditioner Unit—Remove Side Covers from Unit by removing 4 screws, using
a Phillips head screwdriver.
2) Short TP6 & TP17 together, either by wire or
, if available, jumper S1-A.
3) After shorting TP6 to TP17, apply power to the unit.
4) The Front Panel Power Indicator (LED) will NOT
turn on.
5) After power has been applied to the unit for about 3 seconds, remove jumper S1-A or open the TP6
& TP17 connection without turning off the power.
Opening Unit
Solder wire from
TP6 to TP17 on
solder side of board.
Version A Testpoint/Jumper Locations Version B
Install Jumper onto
S1-A on component
side of board.
6) The communication parameters now have been restored to the default settings temporarily in
RAM memory. (If power is removed from the unit, the RAM memory will be lost and the
communication parameters will be lost.)
Page 4
7) To read the default communication parameters, type the following command using
HyperTerminal or some other terminal communication program.
^AE01
8) The unit will respond with the following ASCII characters depending on the model of iDRX
unit.
PR/FP/ST TC/RTD/ACV/ACC
2A011C0D 2A01140D
9) The ASCII response is decoded below:
2A = Recognition Character = *
01 = Unit Address = 01
1C = Command Mode, Multipoint Address, Echo ON, Checksum OFF, Line Feed OFF
0D = 9600 Baud, Odd Parity, 7 Data Bits, 1 Stop Bit
10) To permanently write the above default communication parameters to EEPROM send the
following sequence of commands:
*01W0B2A Unit Response = 01W0B
*01W0A01 Unit Response = 01W0A
*01W081C Unit Response = 01W08
*01W070D Unit Response = 01W07
*01Z01 Unit Response = 01Z01 LED on iDRX unit will blink
11) The default communication parameters are now permanently stored in the unit’s EEPROM
and will not be lost upon power removal.
12) Use the iDRX Set-up Program to establish communication with the unit.
13) This procedure will not affect calibration. It only resets the communication parameters to the
factory default settings.
