Configuring Communication Port of Nokeval 7470
One or several Nokeval devices are connected to the QML logger
through an RS-485 communication port. The device can be connected
to the following RS-485 ports:
- Integrated RS-485 port (COM1)
- Isolated RS-485 port (2-wire or 4-wire connection)
In the Optional hardware view of Lizard Setup Software, configure
the selected RS-485 port as follows:
1. In the Line parameters frame, leave the default values (9600, 8, 1,
none), unless the Nokeval device is to be otherwise configured. See
Figure 18 on page 54 .
2. In the Wiring options frame, select the Two wire connection type
from the list (isolated DSI485A only).
3. Leave all options unselected in the Handshake options frame.
