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 recorder or datalogger (master). The current AquaVent 5 and previous AquaVent loggers are able to act as an SDI-12 Sensor in an SDI-12 network simply by using the AquaVent 5 SPX Wellhead or AquaVent SPX Wellhead, and SDI-12 Connector Cable.
Note:
As features differ slightly between models, it is recommended to use the AquaVent 5 SPX Wellhead with an AquaVent 5 logger.
The SPX Wellhead (translator) converts SDI-12 commands to the Solinst communications protocol for the AquaVent. The SPX Wellhead and SDI-12 Connector Cable provide a hardware and protocol conversion interface between a Solinst AquaVent and an SDI-12 network.
