Missing pulses!

TolpuddleSartre:
What happens when you increase the speed of Serial?

But we can't since we have to adapt to the instruments baud rate that we can't alter? And if the manufacturer could get it to work in 19200 it should be possible...

We continue experimenting with additional flags and buffert-variables, and have seen some improvements.

Hi,
Ops 485 to 232 board,
SKU108443 (5).JPG
How are you powering the drawstring?
Doesn't the device have any info on it, or is it custom made and the drawstring unit is inside the housing?

Thanks.. Tom... :slight_smile:

We power the instrument (real name Penetration logger) with external 12 volts. Yea its custom made...

Half of it is drawstring housing and half is a water proof housing with some intelligence.

The data string out of the instrument pulses slowly + + + + + + + + + + + +

But when you pull the string A:s appear in o much higher frequency... As we've seen just monitoring it.

Hi,
What does;

digitalWrite(MAX485_DE, 0);

do?

Tom... :slight_smile:

It tells the RS485 to RS232 converter which mode, in our case to read. Its hooked up to the pins DE and RE on the converter.
