The Solinst Leveloggers can also be connected to an SDI-12 data logger using the Solinst SDI-12 Interface Cable attached to a direct read cable.
SDI-12 (Serial Data Interface at 1200 Baud) is a communications protocol designed to allow the interfacing of a number of low power analog sensors with a common SDI-12 reader or datalogger. The Solinst Levelogger Edge, Barologger Edge, Levelogger Junior Edge, LTC Levelogger Junior, Rainlogger Edge, Levelogger Gold, Barologger Gold, Levelogger Junior, and Rainlogger are able to act as SDI-12 Sensors in an SDI-12 Network simply by using the Solinst SDI-12 Interface Cable.
The SDI-12 Interface Cable converts SDI-12 commands to the Solinst communications protocol for Solinst Leveloggers. The SDI-12 Interface Cable provides a hardware and protocol conversion interface between a Solinst Levelogger and an SDI-12 network.
Solinst 2-wire signals are converted to SDI-12 signals by the Solinst SDI-12 Interface Cable. One end of this cable has three wires which connect to an SDI-12 datalogger. These wires are colour-coded according to Table 1-1. The other end of the cable terminates in a Direct Read connection. This connects to the top of a Direct Read Cable for connection to a Solinst Levelogger. The Solinst Levelogger has a self-contained battery and does not use +12V DC power. The SDI-12 Interface Cable circuitry requires the 12V connection. The current draw is nominally around 15 - 25 mA at 12V DC.
The communication settings for the Solinst SDI-12 Interface Cable hardware
comply with the SDI-12 standard at 1200 baud, 1 start bit, 7 data bits, 1 parity
bit (even parity), and 1 stop bit.
