SDI-12 Operations
XL™ Series SDI-12 Operations 14-1
14.1 SDI-12 Overview
The XL™ can operate as an SDI-12 sensor, as an SDI-12 data logger, or as both, an SDI-12
sensor and data logger simultaneously. This chapter is split into four sub sections based on the
major options the SDI-12 section supports.
1 - SDI-12 test mode including the transparent options and the full screen mode.
2 - SDI-12 Logger mode setup options.
3 - SDI-12 Sensor mode setup options.
4 - Built in support for the H-310 and the H-330 / H-331
5 - SDI-12 Supported commands, (sensor mode).
14.2 SDI-12 Transparent Mode and Full Screen Mode
The SDI-12 Transparent options allow the user to talk directly with SDI-12 sensors. This mode
allows the user to setup, test, and control SDI-12 sensors. All SDI-12 sensors must implement a
set of standard commands. When using the XL™ these standard commands can be sent to a
sensor using a single key press. Extended commands specific to each sensor may also be sent to a
sensor, but the user must enter these commands based on the sensor manufactures requirements.
