Connecting the RS-232 Interface

Connecting the RS-232 Interface
The RS-232 data communication interface supports the querying of status information and
temperature data from the incubator by entering basic commands in a standard terminal
window provided by your computer's operating system. The interconnection requires a
standard RS-232 cable with 9-pin connectors and a straight "1:1" pinout without any crossed
wires, which is not supplied with the incubator.
Users may employ the RS-232 command inventory listed in
process data logging - for example, by embedding these commands in scripts that run on a
remote computer.
Interconnecting the Incubator with a Computer
1. Turn the computer off.
2. Route the serial interface cable along a path that does not cross hot exhaust air piping,
tables, aisles or passageways.
With stacked devices, keep the serial interface cable away from hot spots on the other
incubator in the stack.
3. Connect one connector of the serial interface cable (cable length, 5 to max. 10 m, not
supplied as a standard item) to the socket labeled RS 223 in the computer and alarm
interface section at the rear of the incubator (see
page
4. Connect the second connector to an unused COM 1 /COM 2 or other serial port on the
computer.
5. Boot the computer.
6. Launch your standard terminal program and set up the connection with the following
parameters:
— 57600 bits per second
— 8 data bits
