5.4 Output function codes.
Output delimiter
The default delimiter can be set by jumpers on
the PM 9696 circuit-board to be either CR, LF or
CR+LF. If neither is selected ETX will be sent
for single measurements (TE1) and ETB will be
sent for repetitive measurements (TE0). The de-
limiter is factory preset at LF.
Fig. 5.4 Delimiter settings.
Choice of output string delimiters
The default value of the output delimiter is set
by hardware jumpers on the PM 9696 circuit board
(factory preset at LF).
The delimiter can be changed by the controller
by sending "SD0"; "501"; "502" or "503".
Note: When 50!11 is selected, the delimiter will
be ETB in free running mode (TE0) and ETX
in trigged mode (TE1).
The EOI-line in the IEEE-488 bus will be active
together with the last output byte sent when
"M51" has been programmed.
