SWVX on CR310

pkeravec Nov 13, 2017 03:14 PM

Hello,

I wanted to use a 5V instrument on a CR310 and as stated in the manual (revision 10/24/2017 p14), I tried to use the SWVX instruction but CRbasic 3.7 didnt recognize the function. Is there a way to solve it?

Installing the last OS for CR310 didn't help at all...

Regards,

Pascal

Use the ExciteV instruction.

You could use either the ExciteV() or the PortSet() instruction for the VX terminals. For the PortSet() instruction, logic high for the VX terminals is 5 V, and low is 0 V.

The SWVX() instruction is in the queue to be added, but I'm not sure when. We'll remove it from the manual until that happens. Thank you for bringing this to our attention.

Thank you for your answers, the PortSet() instuction did the job. The only thing that bother is the voltage drop (4.85V when loaded by a 150mW sensor). It doesn't matter that much as the supply voltage stay in the tolérance of this sensor,
