Probe Configuration
Introduction
Before installing a Sentek PLUS system in the field, the probe must have the following configured:
number of sensors detected and depths set
air and water counts normalized
sampling interval set
clock synchronized
Sentek PLUS specific settings (explained in detail below)
Some applications may also require configuration of the Calibration Equation constants and Power
settings, although the default settings are usually sufficient.
Each of these procedures will be explained in the order that they should be performed. Additional
information can be found in the Probe Configuration Utility manual.
Connecting to probe
The Sentek PLUS probe can be configured using either the DTU Front Panel connection or the probe
interface TTL port. However, there are some limitations in using the Front Panel connection, such as; not
being able to use any features that utilise the modem. Therefore, it is recommended that the probe TTL
port is used.
The USB Probe Programming Cable (PConfig Cable) is used to communicate through the TTL port.
Drivers for this cable must be installed before the cable is connected to the computer. Instructions on how
to install the cable drivers can be found in Sentek Technical Brief
TB069-PConfig USB cable driver
installation instructions.
1. Use the Probe PConfig Cable to connect the TTL port of the interface to your computer.
2. Open PConfig,
3. Select the serial port that has been assigned to the cable
4. Select the baud rate of the interface TTL port (default = 9600)
5. Ensure that the DTU is switched on and press
Connect
. The PConfig software should now establish
communications with the probe.
