Page 7: Wiring Connections
GP-USB Connect - SDI-12 Sensor (Part# 6300) is a USB to Sensor interface that connects sensors directly to application software on a USB equipped computer. GroPoint™ accessories are listed in appendix E of this manual. Sensor Start Up Time / Measurement Time Important Things to Note The time from application of power to the SDI-12 power bus until the sensor is ready to receive a command is approximately 350 ms. -
Page 8: Basic Sdi-12 Command List
Responses from the sensor always include the sensor’s address as the first character and are always terminated with the <CR><LF> (carriage return-line feed) sequence. Basic SDI-12 Command List The GroPoint™ Lite Profiling Probes respond to the following basic SDI-12 commands. In all cases, = sensor address. Default sensor address is ‘0’. -
