ASCII Command Structure
The commands are defined as case-sensitive ASCII characters. Format
is defined as:
Note:
The < and >
characters are part of the
command and must be
typed. The brackets [ and ]
are field delimiters and are
not typed.
<xx [yyyy]>
where:
< = Start Character
Note:
The commands
are case sensitive. If an
incorrect case is used,
there will be no response
from the instrument.
xx = Command Character
yyyy = Optional Command Parameter
> = End Character
Handshake
Upon execution of the command, and assuming the user has typed <V>
for Verbose, the REMOTE instrument will send a response based on
the command sent.
When the unit is powered up, it sets up the counters and timers, and
starts reporting data. The data will be similar to this example:
Note:
the field bk= 371
in this example, is the
"backlight" function, which
is a measurement of
scattered light in the
instrument.
371mV=.371V
Sample: 0, 0; bk= 371; trh= 74.7/ 43.0; rec=95;
Sample: 0, 0; bk= 371; trh= 74.7/ 43.0; rec=96;
If the unit is a 4-channel instrument, the following would display:
Sample: 0, 0, 0, 0; bk= 371; trh= 74.7/ 43.0; rec=95;
Sample: 0, 0, 0, 0; bk= 371; trh= 74.7/ 43.0; rec=96;
If an invalid command is typed, there will be no response.
