Is this because the sensorPowerPin is the same for the CTD sensor and for the 511a?  Or is my setup configuration incorrect?

Also anyone k…[Read more]

in my code.  Works now!

Emailed you the current code.

Thanks!

I’m waiting for a USB to RS485 adapter to try to use the smartpc utility to see if calibrating the unit will do anything, as well as see if the units are working correctly.

 

Thanks.

I used mostly the same code but replaced the GUIDS and inserted into the originally working code for one of our current stations.

I initially tried with 0x01, and just tested again with 0x01.  The wiper wipes 3 times and stops.

Readings for temp and turbidity are still -9999.0 and -9999.0.

Thanks.

issue with the sensor.

Using the Yosemitech 511-a, with the regular code[snippet below], on a ver 1.1 mayfly, using the older modbus wing.

I get

YosemitechY511 at modbus_0x02 reports temperature is -9999.0 degreeCelsius

The sensor turns on, wipes back and forth 3 times, I…[Read more]

I think Rachel showed me an awesome page on the monitormywatershed.org site that allowed me to track and log information when you visit a station.  Would anyone know where that is or how to get to it?  I can’t seem to find it now.

Thanks!
