II.10.4 Comments on Print Mode Operation
The high-speed-print jumper (between pins four (4) and nine (9) on the RS-232 plug found on the
Brookfield PC Cable - Part No. DVP-80) is used exclusively with Brookfield’s DVGATHER+ and
WINGATHER software. This jumper if in place will override all of the above and will immediately
place the DV-II+ into the maximum print speed mode. When in this high speed print mode, the ability
to access either of the timed modes from the front panel will not be allowed and PRINT key presses
will be ignored. When the user returns to stand-alone operation with a printer, you will remove the
Brookfield PC cable (with the high-speed jumper) and replace it with the Brookfield Printer Cable
(Part No. DVP-81) or any standard serial printer cable which will re-enable the print modes described
above.
Additionally, the DV-II+ user can set up a desired print interval time, then set the viscometer to the
continuous print mode and finally initiate either of the timed modes of operation. While setting up
timed mode parameters, continuous print operation will cease. However, upon starting the timed
operation, the DV-II+ will output an initial data string to the printer and then continue printing data
strings (at the user defined time interval) for the duration of the timed run. At the end of the timed
run, continuous printing will again be disabled and the user may print single strings (of the final data
point) at your option until exiting the timed mode. Upon returning to the default operation mode,
continuous printing will again resume at the user selected time interval. In a similar manner, if the
user is in the one-print-per-key-press mode when entering the timed mode of operation, you will be
able to print data strings at any time during the timed mode by pressing the PRINT key when output
is desired.
