Enter Talk Only Mode
The main purpose is to transfer streaming data fast in monitoring systems without
predefined limits for time or number of samples. It is a non-reversible command,
i.e. you can only return to normal bus mode by sending IFC or pressing the CAN
-
CEL button on the front panel.
The Talk Only output buffer can hold one value. If a new measurement result is
ready for output before the previous one has been transferred, the new value is
rejected and the previous transfer is left undisturbed.
Consequently a pause during the reading will cause the first value read after the
pause to be the first measurement finished after the latest pre-pause value was
read. The second value read will be that of the most recently finished measure
-
ment. All values in between are lost. The same applies if there's a pause between
turning on Talk Only and starting to read values. So, a dummy read is recommend
-
able in many cases.
