Your communications software will most likely have a setup routine to set
the parameters listed below. These are the values the incubator is using, so
the computer parameters must match accordingly. Also, you will probably
have to select the “COM” serial port you chose when you connected the
cable from your computer to the incubator. The software may ask what
format the data is in. You should choose “ASCII”.

The incubator transmits information on its RS232 port as long as the
status update time interval is not “0.0.”
If you start your communication software with the incubator on, most
likely you will see the error(s) messages as follows:
ERR
? VALUE IS READ ONLY
? ILLEGAL COMMAND
Wait for the Status Update Time duration you selected to complete, and
the communications will correct itself.
Besides having the incubator transmit information in one of the three
formats, the user can monitor other values or even change some of these
from their computer.
