Interface & Data Logging Module – Port.8
develogic multifunctional interface and data logging module features 8 serial ports (2 x RS232/422/485 and 6 x RS232) and SDHC/SDXC based data logging functionality with now up to 128GB storage capacity.
Each high speed serial port operates with baudrates up to 230kBaud supported by a 64 byte hardware FIFO. Two ports are individually configurable to RS232/422 and again six ports are RS232 with hardware handshake.
A continuously adjustable DC/DC converter provides supply voltages in the range of 5V to 12V to any of the serial ports (routing is software programmable). Supply voltage switching can be triggered by the internal scheduler, external devices or command interface. Maximum current for supply voltage is 4A.
The 24-bit analog-to-digital converter that is available on an add-on board allows sampling of up to eight analog input channels (single-ended; four in differential mode) with software selectable data rates. It has interface opportunities as well as a temperature sensor, compass and accelerometer.
The Port.8 modules primary applications include data logging and data routing in buoy based and ocean bottom sensor systems either standalone or in combination with any of our telemetry systems. Due to the low power consumption, Port.8 is ideal to be used for long-term deployments.
The develogic Port.8 module seamlessly integrates with all our other communication system building blocks such as acoustic modems, VHF/UHF/Iridium communication solutions and auxiliary systems such as our navigation lights, power management modules etc.
In order to minimize data traffic over energy consuming and/or expensive communication links, the system provides extensive data filtering possibilities.
The firmware also contains drivers to control many of the most common oceanographic instruments (including AADI, Seabird, RDI sensors).
