Data) and RxD- (Receive Data) wires to be crossed with a common ground line (GND) for both de-
vices. This creates a bidirectional bus that allows full-duplex communication. The communication
partners can therefore send and receive data simultaneously.
Data transmission via UART is performed with a fixed data frame (UART frame). This frame must be
known to both communication partners. It consists of: A start bit, 5-9 data bits, an optional parity bit
and one or two stop bits. If a PC is connected to the analyzer, the necessary settings are typically
identified automatically. If this is not the case, the parameters can be set manually according to
Table 10.2. (see Section 10.1).
Only a few PCs are still delivered with a so-called COM port (serial RS-232 interface). In order to be
able to operate and program devices that have an RS-232 interface with computers without this, use
of converters from RS232 to USB is advised. The converters often have a 9-pin D-Sub connector as
input, but there are also converters with screw terminal connections.
The serial interface allows operation of the instrument and the display and storage of
measurement data with the SetApp program. More information and a link to download
the software can be found at www.messkonzept.de.
If you plan to develop or use your own software solutions for communication via the
RS-232 interface, you may need more detailed information on the available parameters,
etc. Please contact Messkonzept in this regard.
