The transmission settings are not modifiable and are:
Parity:
Without
Format:
8 bits
Stop bit:
1
To change the speed of transmission, go into the Config menu, on the interface line and se-
lect RS232. In the Bit/s area choose the flow by scrolling through the values between
1.2 kbauds and 115.2 kbauds. Validate by pressing the desired digit.
A command destined for the device
must
end with the character:
LF
(hexadecimal
0A
,
decimal
10
).
The codes can be sent in upper case or lower case. The maximum number of commands
in the same block must not exceed 15 instructions.
Take care not to associate normalized
orders or queries with other types of commands.
The end of the execution of a block of commands by the device is reported by the issu-
ance of the XON character (hexadecimal
11,
decimal
17
) and allows us to synchronize the
communication with the computer which must wait for the
XON
character before sending
the next blocks.
Events occurring during the measurement can be reported to the computer by the issu-
ance of a character Z
(format errors, end of test, safety loop open, etc.). To activate this
function it is necessary to send the
SRQ
code after initialization of the device. On receipt
of the character
Z,
a special command allows the computer to recognise the event precise-
ly (see Commands
*STB?
and
*ESR?
).
In the case of incorrect syntax the message
: dialogue error 1
is displayed. In the case of a
code out of context the message:
dialogue error 2
is displayed (a code specific to a func-
tion when we are not in this function, or a digital value outside the limits).
