ENVIRONMENTAL CHAMBER ONLY
To use the Environmental Chamber only, within the
MIXER MODE
, choose the setting
OFF
. All mixing
will become disabled and the
Enviro-Genie
becomes a temperature chamber only. A wire rack
is included to increase the capacity of the chamber.
An additional rack (sold separately) may be stacked
on the first rack to further increase capacity (see
Accessories).
RS-232 INTERFACE
Enviro-Genie
comes equipped with a serial
interface for connection to a PC or other serial
device. This interface can be used to record
machine information (including temperature) for
situations that require verification. It can also be
used to send commands remotely to the
Enviro-
Genie
, either manually or automatically from a
program in order to create profiles. Visit our
website (www.scientificindustries.com) for a sample
visual basic control program for the
Enviro-Genie
.
The serial port is on the side of the unit and is a
standard subminiature 9-pin male connector.
Connection to a PC is via a straight through 9-pin
female-female serial cable (P/N SI-1132).
