plastic.
SERIAL INTERFACE RS 232C
The instrument is equipped with the standard serial interface RS 232C, galvanically insulated; it is
supplied with the adapter cable CP RS 232C. The following signals are available on the SUB D 9-
pin male connector of the instrument.
NOTE: The deflector on the connector of the adapter cable CP RS 232C must be turned to COM-
PUTER or PRINTER position, depending on the chosen connector (this may not be true on
some computers or printers).
The signals present in pins 2 and 3 are at logic levels compatible with the standard RS 232C.
The transmission parameters with which the instrument is supplied are:
* Baud rate
19200 baud
* Parity
None
* No. bit
8
* Stop bit
1
* Protocol
Xon/Xoff
The data transmission speed may be changed by pressing the PROG key on the instrument to alter
the set-up parameter P3. The possible baud rates are: 19200, 9600, 4800, 2400, 1200, 600, 300.
The other transmission parameters are fixed.
All the messages reaching and leaving the instrument must be inserted in a "Communication fra-
