Choose related data (heat or volume) to use with DO.
Choose the value (totalizer or heat) that represents
one pulse.
Example: To get a pulse at the DO each 10m3 enter 10
here. Units can be changed in units setup.
i
The unit in the digital output menu (for example,
m3) is related to the chosen unit of the counter
(totalizer). Example: Choosing unit l (litres)
for the totalizer in the units setup menu also
provides litres in the DO.
Choosing kWh as unit of the totalizer when
using it for heat measurement also provides
kWh in the DO.
SETUP THE SERIAL INTERFACE
RS232
Using a separate RS232 interface board is an option.
QStar UFM upgrades by simply plugging in the separate
RS232 board. The RS232 sends ASCI strings including
measurement data.
UPGRADE QSTAR UFM
Disconnect transmitter from power supply. Plug the
RS232 board (QMF-RS232) into the two plugs in the
region of the connection terminals (see
QStar UFM and
Components: Interfaces of QStar UFM
” to access
the connection terminals).
RS232 Board (QMF-RS232)
Now reconnect the power supply.
CONNECT RS232 BOARD TO A
RECEIVER (PC OR PCS)
Requires a cable to be connected at the RS232 board
and –typically- to a SubD (others possible due to cus-
tomers demands).
