Title: ADC VOLTS
Post by: philipjoseph on October 26, 2003, 06:30:52 AM

HI,
I HAVE A T100MD1616, I'M TRYING TO USE THE ADC TO SENSE THE TEMPERATURE USING A THERMISTOR 10K @ 25 C.

I CHECK THE VOLTS AT THE +5 VOLTS AND IT'S ONLY 1.2 VOLTS. I ADJUSTED THE AVcc POT BUT IT ONLY CHANGES FROM 0.5 TO 1.2 VOLTS.
I DON'T KNOW IF I HAVE TO CONNECT THE 24 VDC FROM THE POWER SUPPLY TO THE +12 to 24 V DC INPUT THAT IS BESIDE THE A/D IO TERMINALS.

THANKS

For T100MD1616+ you need to provide the 24V analog power supply to its designated terminal. Please refer to the T100MD1616+ installation guide for details.
