4.6.3 RS232 Protocol
The RS232 protocol can be set to “
ASCII
”, “
DIAGNOSTICS
”, “
PRINTER AUTO
” or “
PRINTER
MANUAL
”.
The
ASCII PROTOCOL
is a protocol similar to the SCPI, a standard protocol widely used
for measuring equipment.
For details on this protocol please refer to the Interface Description (kins22e1).
Diagnostics
The
DIAGNOSTICS
protocol is a binary protocol used for analysis in quality control and
trouble shooting during manufacturing and service.
Default setting:
ASCII
Printer Manual
The
PRINTER MANUAL
protocol allows to send leak rates on pressing the right sniffer
probe button. One line will be send for each currently enabled gas.
Notice: When in any of the two printer modes, no
ASCII
commands must be sent to
the Ecotec E3000 as this will interrupt the printer mode.
When set to I·Guide mode the
PRINTER MANUAL
mode is without function.
Printer Auto
In
PRINTER AUTO
the leak rate will be sent any time the set trigger level is exceeded.
At the time the signal drops below the trigger level the maximum detected leak rate
will be sent only for the gas(es) that exceeded the trigger.
When set to I·Guide mode the leak rate results will be sent after each test point
together with the test point number.
After the test cycle has been completed, the summarized global leak rate will be sent.
