Connecting the USB Interface
The units come equipped with a USB interface as a standard feature. The connection to a computer is
made using a commercially available USB 1 or USB 2 cable (incubator side: USB male connector of
Type B, computer side: USB male connector of Type A.
The USB interface complies with Standard USB 1.1 and is compatible with Standard USB 2.0 and 3.0
(full speed). Data communication between the computer and incubator across the USB interface
requires that suitable driver software be installed on the computer, unless such software is provided by
the currently installed Windows-version. The installation of the driver software is described in
“Data
Communication” on page 12-1 .
The bit rate of the interface can be changed within the pre-set Baud rates limits (9.600, 19.200,
38.400, 57.600 Baud). Baud rate adjustment is described in section
“USB Interface Baud Rate Setting”
on page 6-23 .
Connecting the Alarm Contact
Function:

When system errors and failures occur in the temperature or gas control circuits, an alarm message is
issued to the connected alarm/monitoring system. The potential-free contact (1 changeover contact)
has been designed for the following circuits:
Alarm relay:
Note
Skilled work:

Thermo Scientific warrants the operational safety and the proper performance of the device only if
installation and repairs are performed properly.

The connection of the device to an external alarm system must only be carried out by adequately
trained and authorized expert electrical/telecommunication personnel!
