- Intelligent Probe and Radio Controller
 IPC
Specification sheet
NEW
- 2004 - GPRS enabled IPC for direc data transfer from field to web.
| The IPC device controls
and co-ordinates the collection and transmission of environmental data
by radio. The device can collect data from voltage, current, RS 485 and
SDI-12 based instruments and provides a radio interface to: -
EIT 433 MHz Datatenna radios
EIT 900 MHz radios
External radios to 5 watts.
( GME / Trio )
The IPC device is housed
in a powder coated aluminum box and fitted with gold plated, IP 66 Binder
sockets and / or terminal connectors for sensor connections. The
IPC can be configured to control data flow in repeater situations as well
as acting as a data collection point. |
 |
| Model IPC - RS
485 / SDI -12 - supports RS 485 and SDI-12 based sensors
Model IPC 4 A - supports
four 0-1 volt analogue sensors |
 |
| FUNCTIONS
The IPC provides data flow
control between attached sensors and a remote base station via radio..
The IPC supports a number
of radio types and can be used to forward data in 'repeater' mode from
low power radio networks to long range using high power external radios.
In multi- unit situations
the IPC can be programmed to act as both a data collecting device and data
repeater unit.
When fitted with an EIT Datatenna,
the IPC can be configured to 'listen' for incoming data over the EIT low
power 433 MHz radio network and re-transmit at up to 5 watts using other
third party supplied radio units. This feature allows the IPC to act as
a repeater for clusters EIT 433 MHz short range radio networks. |

| EIT
IPC units and data recording stations are frequently deployed for the measurements
of soil moisture in irrigated agriculture. Soil moisture probes can be
attached to the IPC unit. The IPC unit scans the soil probes and transmits
data via radio to a central EIT Base station. Data from the Base stations
then downloaded and viewed to determine plant water requirements.
Data can be
exported from the EIT data recorder to third party irrigation scheduling
software as supplied by Sentek Technologies. |

| Applications |
For use where radio is required
to provide a data link between remotely positioned sensors and a base station
data recorder or PC. The IPC controls the 'power up' functions of sensors
and radio thus greatly reducing field power requirements. |
