6 CONFIGURATION
Configuration mode allows to read the instrument general info (firmware version, serial num-
ber, …) and to set the instrument operation mode and operation parameters. The configura-
tion of the instrument can be done in two ways:
•
With the aid of HD52.3D-S application software (see the software online help), down-
loadable from Delta OHM website.
•
By sending serial commands (listed in paragraph 6.1) via a standard communication pro-
gram.
If a standard communication program is used, the program communication parameters should
be set as follows:
•
Baud rate = 115200
•
Data bits = 8
•
Parity = None
•
Stop bits = 2
•
Flow control = None
For the configuration, the instrument can be connected to the PC:
•
Via auxiliary RS485 (see paragraph 5.2.6 for the connection), except the models meas-
uring temperature and relative humidity.
The auxiliary RS485 serial output is always in configuration mode and therefore it is al-
ways available to receive commands from the PC.
•
Via RS232 (see paragraphs 5.2.1 and 5.2.7 for the connection).
The instrument can receive commands from the PC via RS232 only if it is in configuration
mode (factory setting, unless otherwise requested).
If the instrument is not set in in configuration mode but in one of the available operating
modes (NMEA, MODBUS-RTU or ASCII proprietary), to enter configuration mode it is
necessary to send
within 10 seconds from power on (if the instrument is already
powered, disconnect and reconnect the power supply) the serial command @ (if a stand-
ard communication program is used) or the request of connection with the HD52.3D-S
application software, if the application software is used.
