Data
logger module with
MMC/Secure
Digital (SD) data storage
designed to plug in to Application Specific Interface Modules (ASIM).
Two ASIM modules have been built to interface with the DL4-GP:
DL4-IO1-Met, and DL4-IO2-GPS-COMM.
The
DL4-IO1-Met provides an interface to a suite of meteorological
sensors: wind speed and direction, relative humidity,
temperature (3 channels), solar radiation, barometric pressure,
precipitation (2 channels), soil/fuel moisture (4 channels).
The
DL4-IO2-GPS-COMM adds three asynchronous serial I/O ports to the the
DL4-GP. One port is dedicated to a Trimble Lassen IQ
12-channel GPS. The two other ports are set up for RS-232
serial communication (RX, TX, CTS, RTS).
