Yosemitech 511-a starting up twice?

Using just the Yosemitech 511a, when it starts up it wipes 3 full times then does a reading.  When I add the code for the Hydros CTD sensor, it seems that the 511a starts up twice and wipes a full 6

Using just the Yosemitech 511a, when it starts up it wipes 3 full times then does a reading.  When I add the code for the Hydros CTD sensor, it seems that the 511a starts up twice and wipes a full 6 times?

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

Also anyone know what is the difference between

const int8_t y511AdapterPower = sensorPowerPin; // RS485 adapter power pin (-1 if unconnected)
const int8_t y511SensorPower = 22; // Sensor power pin

sensorPowerPin is defined as 22 as well?

 

Thanks for any insight.
