56Note:It is not necessary to know the serial communication protocol (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. 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. ItÕs 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 accidentally disconnected.Operation:Power Input and Analog Output Setup:To connect the signal input proceed as follows:1.Connect a DC power supply with an output voltage between 10 to 32Volt DC to the signal conditioner (J1).Note:If power supply used has current limiting, it may not be able to power the signal conditioners if the available output voltage is around 10Volt, since the peak current may reach 1to 5 amp for a few milliseconds.2.Determine the maximum voltage to be measured.3.Determine the appropriate input signal range, i.e. ±20mA;±400mV, ±1Volt, ±2Volts, ±5Volts, or ±10V olts.4Ensure that if the selected range is different from the defaultthen change the internal range which is controlled by the software by using serial communication explained later in this manual.5.Connect the signal input to screw terminal, and ensure that the screws are tight. Connect voltage sources to pin 2 of J2and current sources to pin 3 of J2.6.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 a DC 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. If the program has not been installed, then insert the 3.5Ó floppy disk in either drive A or B. From the Program Manager choose File, Run; in the command box type either A: setup or B: setup according to your drive designation. The program will create an icon for the signal conditioner. You may start the program by clicking on this icon.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.M2525/0201DRN-PRProcess Signal ConditionerIt is the policy of OMEGA to comply with all worldwide safety and EMC/EMI regulations that apply.
