Connecting the Optional Printer
The A
CCU
B
ALANCE
can be used with an optional portable printer. The
printer provides hard copy of selected flow rates and eliminates the
awkward task of manually recording flow rates while operating a flow
measuring hood. To connect a TSI Model 8925 Portable Printer to the
A
CCU
B
ALANCE
, locate the interface cable that was shipped with the
printer. The cable has a modular RJ-45 (telephone type) connector on
one end and a 9-pin D-connector on the other end. Simply connect the
9-pin D-connector to the printer and the RJ-45 connector to the
A
CCU
B
ALANCE DATA PORT
. If you find that the printer prints only
question marks "?", turn the printer off and then on again. For details
about how to operate the Model 8925 Portable Printer, refer to the
manual that was shipped with it.
