the logger as normal.
Please note that each logger connecting to the same port of the Konect router
must have a unique Pakbus address which, if not the default of 1, must be set
using the Device Configuration program. Please also take note of the
warnings cautions and notes at the end of the section above.
3. Specifications and general considerations
3.1 Specifications
The COM111 specifications are:
Input Power Supply voltage and current:
5-32V DC (capable of supplying up to 400 mA continuously and
2A spikes)
System Power Consumption:
Typical: (modem only) 5 mA in ‘standby’ mode (GSM)
<400 mA on-line, transmitting (typically 100-200 mA)
~ 20-30 mA when online in GPRS/3G mode.
Frequencies supported:
Quad band GSM/GPRS/EDGE 850/900/1800/1900 MHz
900/2100 HSDPA (3G) for Europe and Asia
Modem serial port speed:
9600 baud for older dataloggers and the CR200X.
115 kbaud for GPRS/3G use with newer loggers.
Physical: (module only)
Operating Temperature: -30°C to +65°C
Humidity: Up to 90%, non-condensing
The specifications for the interface devices included in the kit, e.g. the
SC105, are given in their respective manuals.
3.2 Power use
As can be seen from above the additional power use of using a COM111
connected to a datalogging system may not be insignificant and can vary
from nothing, when powered off, to several hundred mA when the modem is
fully powered and sending data at high speed to a distant base station. Even
when not communicating, if the modem is left powered on, its power use can
