The HD32.1 is fitted with an electrically isolated RS-232C serial interface, and an USB 2.0
interface. Optionally, they can be connected using a serial cable with sub D 9-pole female
connectors (code 9CPRS232 ) and a cable with USB 2.0 connectors (code CP22 ).
The USB connection requires the previous installation of a driver included in the DeltaLog10
software package. Install the driver before connecting the USB cable to the PC (follow the
instructions included in the software package).
Standard parameters of the instrument RS232 serial transmission are:
• Baud rate
38400 baud
• Parity
None
• N. bit
8
• Stop bit
1
• Protocol
Xon/Xoff
It is possible to change the RS232C serial port baud rate by setting the " Selection of the serial
transmission speed (Baud Rate) " parameter in the menu (please see the menu on chapter 5.3.1 The
Baud Rate). The possible values are: 38400, 19200, 9600, 4800, 2400, 1200. The other
transmission parameters are fixed.
The USB 2.0 connection does not require the setting of parameters (Baud rate = 460800 fixed).
The selection of the port is carried out directly by the instrument: If the USB port is
connected to a PC, the RS232 serial port is automatically disabled, and vice versa.
The instruments are provided with a complete set of commands and data queries to be sent via the
PC.
All the commands transferred to the instrument must have the following structure:
XXCR where: XX is the command code and CR is the Carriage Return (ASCII 0D)
The XX command characters are exclusively upper case characters. Once a correct command is
entered, the instrument responds with "&"; when any wrong combination of characters is entered,
the instrument responds with "?".
The instrument response strings end with the sending of the CR command (Carriage Return) and LF
(Line Feed).
Before sending commands to the instrument via the serial port, locking the keyboard to avoid
functioning conflicts is recommended: Use the P0 command. When complete, restore the keyboard
with the P1 command.
