Multi-Cal PGA309 Issues

Other Parts Discussed in Thread: PGA309

Hello,  

            We are having a little trouble with the Multi-Cal System for the PGA309 I have been looking for the source code and have not been successful. The software I am using is sboc401a is this the newest version? What would the D-Sub pin out be to hook up the sensor to the D-Sub 9 connector? When using the program if I set the first temperature to 37.7°C it asks to set the temperature to 0°C am I not setting it up right, also is there a way to set it to °F?

Thanks,          

            Jim

    Hello Jim,

    I'll send you a link where you can download a new, unreleased but tested version of the Multi-Cal PGA309 software. The calibration procedure ignoring your temperature range and defaulting to 0-100C was a known bug and has been fixed. Unfortunately we don't have Fahrenheit available in this version.

    If you wish to connect your own sensor module to a D-SUB9 connector on the interface board, the pinout is as follows:

    1. One-Wire interface
    2. Vcc (voltage output mode), Vloop (current output mode)
    3. GND (voltage output mode), Iout (current output mode)
    4. GND
    5. Vout (voltage output mode)
