I would like to have code written that sends a command to initiate the wiper process before the sonde starts its sample period. Again, would this be hard coded or part of the sonde’s deployment setup? Hi @cmchrist! My understanding is that every time the sonde makes a measurement, either via internal sampling or by a command, the wiper will begin a wipe and then a measurement is taken. In the [EXO3s integration](https://bristlemouth.discourse.group/t/bm-sensor-integration-sdi-12-multiparameter-sonde-exo3s/399), I send a command via SDI-12 communication interface to ask the EXO3s to make a measurement. It begins a wipe, and ~62 seconds later sends over one set of readings. We haven’t tested an internal sampling scenario yet. I think the RS232 command to get the EXO2 to make a measurement is different from the SDI-12 command. But on the [EXO manual](https://www.ysi.com/File%20Library/Documents/Manuals/EXO-User-Manual-Web.pdf) page 43, they list a RS232 extended command `twipeb` to start a wipe. Have you had a chance to try this command and see if it works for your case? --- _[View the full topic](https://bristlemouth.discourse.group/t/application-development-for-integrating-ysi-exo2-sonde-into-smart-mooring-using-bristlemouth/370)._
