3. Determine the appropriate input signal range, i.e. 400 mV,

4 Volt, 40 Volt or 400 Volt. Also ensure that the frequency of

AC source is within the specified limits.

4. Ensure that if the selected range is different from the default

then change the internal range by using the Setup Software

and select the appropriate range.

5. Connect the signal input to screw terminal, and ensure that

the screws are tight. Failure to do so may cause electrical

shock should the wires become loose and come out of the

screw terminal.

6. To verify that the set up is correct, you may connect a DVM

to the analog output. Once connected, power the signal

conditioner and apply a known voltage from an AC source to

input. Measure and compare with expected values. To

custom scale the analog output proceed to the next step.

7. To view/change the scaling that relates the analog output to

signal input: connect the RS232 output of the signal conditioner to

an available serial port of a computer. The cable and the DB9 or

DB25 connectors are available as an option.

8. Turn on the computer, start Windows 3.0 or higher and run

the Signal Conditioner Configuration Setup Program.

9. Start the configuration program, you need to indicate which

serial port is to be used for serial communication by checking

the appropriate check box on the opening menu.

Note: It is not necessary to know the serial communication

protocol. i.e. baud rate, parity, 7/8 data bit and stop bit; the

program will determine this information automatically.

However, it is good practice to mark the protocols used on the

signal conditioner label if different from default.

10. Once the program starts it will automatically detect the

signal conditioner configuration and will display a window of

available options. To view the signal input click on the

display on/off.

11. To change analog output scaling choose analog output

scaling and enter the desired values.

12. Once the custom scaling is finished, ensure that Send

Configuration is clicked, otherwise the changes will not take effect.

13. The input/output scaling may be fine tuned, while both

communication and analog output are active. In fact you may

make a change to the analog output in the configuration

program, and watch the DVM connected to analog output of

the signal conditioner follow the new settings.

14. You may save or print a particular configuration by

selecting the file menu. It's always a good practice to both

print and save the scaling of each signal conditioner.

15. If the program is not able to establish communication then

an error message is displayed. This happens either when the

wrong serial port is specified or when the cable is

disconnected.

16. The procedure to disable Continuous Mode and change

the iDRN to Command Mode is as follows:

Using HyperTerminal, or any serial communication program,

type: Ctrl + S

To change the device to Command Mode, type: ^AE

To change the Bus Format Register, type: *W0814

To reset the device,type: *Z01

Cycle power to the unit.

d. The decimal point register has to set to: 1, 2, 3, or 4.

2) Bus Format: Bit 5 1/0 = Modbus/Newport

3) Output Scale/Offset Write:

Due to write single only, two write operation is needed to

write scale/offset, and to make it effective it needs to

follow with Hard Reset command.

4) To configure to Newport protocol, set bit 5 of Bus Format

to low and follow with Hard Reset command.
