Envco – Environmental Equipment

There are four physical communication interfaces:
· RS232
· GSM/GPRS or CDMA-1X or HSDPA (Next G®) modem
· SDI-12 Serial Instrumentation
· Serial Camera
Data may be accessed / downloaded in several ways:
· Direct RS232 connection e.g. laptop or data radio
· IP based packet transfer
· CSD dial-up data link
· SMS text back (immediate values only)

Size
160mm x 130mm x 70mm (6.29in x 5.11in x 2.75in) (WxHxD)

Mass
1300g (2.86lb)

Power Supply
Internal and/or external 12V SLA battery. Lowest
power mode current ~ 3mA. An integral charger accepts a 15-30Vdc
input. A solar panel can be directly connected to the charger input.
Over-voltage and reverse polarity protected with self-resetting fuse.

Communications
- Non-isolated DTE RS232 at 1200 - 115200 bps (default 38400 bps)
- Multi-band GSM/GPRS or CDMA-1X or HSDPA (Next G®) modem.
- SDI-12 instrumentation port.
- Serial VGA camera proprietary connection (3.3V CMOS levels)

Non-Volatile Storage
8MB flash memory (1,084,576 samples). A typical
site with 2 parameters logged every 15 minutes plus battery voltage
logged hourly will give 12 years of storage before data overwrite occurs.
