6 CONFIGURATION
Configuration mode allows to read the instrument’s general info (firmware version, calibration
date, serial number), to set the operation mode, to read and set the instrument operation pa-
rameters.
To configure the instrument, a RS232 serial connection to a PC should be performed (see par-
agraph 5.2.1). If your PC is not equipped with RS232 serial ports, the RS52 adapting cable can
be placed between the PC and the instrument (see paragraph 5.2.6).
Communication parameters should be set in the PC as follows:
 Baud rate: 115200
 Data Bits: 8
 Parity: None
 Stop Bit: 2
The instrument configuration can be realized with the aid of the HD52.3D-S application soft-
ware (see the instructions of the software) or by sending serial commands via standard com-
munication programs.
The configuration procedure by sending serial commands slightly differs depending on whether
the instrument is set in configuration mode (factory setting, unless otherwise requested), or
whether it is set in one of the available operation modes (SDI-12, NMEA, MODBUS-RTU, pro-
prietary RS232, proprietary RS485).

NSTRUMENT SET IN CONFIGURATION MODE
(factory setting)
If the instrument is set in configuration mode, at power-up it remains waiting to receive the
configuration serial commands described in the following tables. To configure and make the in-
strument operational, the following should be performed:
 Send command for operation mode selection (see table Operation Mode described at
paragraph 6.1 “Serial Commands”).
 Send commands to set the parameters of the selected operation mode (see tables de-
scribed at paragraph 6.1 “Serial Commands”).
 Send commands to set operational general parameters (parameters independent from
operation mode)
 Turn the instrument off and on. The selected operation mode will become active after 10
seconds from restart.
Note: configuration commands can be sent in any order, it is not necessary to respect the
indicated sequence.

I
NSTRUMENT SET IN ONE OF THE AVAILABLE OPERATION MODES
If the instrument is set in one of the available operation modes, when started up it remains
waiting for a serial command for 10 seconds. For instrument configuration, the following
should be performed:
 Send the following command to the instrument before 10 seconds have elapsed:
@<CR>
with <CR> = ASCII character Carriage Return.
If the instrument doesn’t receive the over mentioned command after 10 seconds from
start up, the operation mode set in the instrument is immediately activated.
 Send commands to change the desired parameters (see tables described at paragraph
6.1 “Serial Commands”).
 Turn the instrument off and on. The selected operation mode will become active after 10
seconds from restart with the new parameter values.
