Serial Interface
The device has a serial interface (RS-232, 9-pin). This is located on the
right-hand side of the device casing. The serial interface is designed
primarily to allow the device to be connected to an external com-
puter in order to control it remotely or record data. The serial inter-
face can also be used to transmit alarm messages.
An optional RS-232 Ethernet interface adapter is available if you wish
to connect the device to a network. You will need this if you wish to
operate the device using the eve
®
software, for example.

Openings
3.6.1
Discharge Outlet
The opening for discharging leaked liquids, detergents or condensa-
tion that has collected is located at the bottom, on the left hand side
of the casing, close to the centre.
The opening is sealed with a yellow plug on delivery. A hose nozzle
(¼ inch) for connecting a hose (Ø 10 mm) is included in the scope of
delivery.
INFORMATION
When working with large fill volumes, we recommend installing
the discharge hose to avoid the bearings coming into contact with
liquid if a flask breaks.
If safety requirements must be met, e.g. when working with ge-
netically modified organisms, the discharge hose must lead to a
suitable, sealed receptacle. One example of such a receptacle
would be an empty chemical container sealed with foil.
