INSTALLATION AND OPERATION
OF THE RS232 OPTION
1.
Remove the eight (8) screws securing the
control panel. There are four (4) on the top
and 2 on each of the sides. Then remove the
cover by sliding it towards the front of the
incubator.
2.
Slide open the auxiliary panel door and locate
the mounting area of the RS232 board as
shown on page 4.
3.
Mount the RS232 printed circuit board
assembly using the screws or standoffs
provided. See Figure below.
4.
Connect one end of the cable to J304 located
on the left edge of the left printed circuit board
(p/n 34381002).
Be careful of alignment.
5.
Connect the other end of the cable to the cable
connector on the RS232 PCB assembly (see
sketch).
6.
Replace the control panel and secure with the
eight (8) screws.
The RS232 PCB provides a bi-directional
communication port that will allow the user to
monitor the performance or the change the
operating valves of the incubator from a remote
computer. RS232 Communication will require a
communication program such as a modem
program installed in your computer which will allow
the storage of data within your files.
The RS232 PCB utilizes one of the users computer
serial ports, such as COM1 or COM2. The
communication software must be configured to the
selected port. The serial port is an IBM PC AT-
style port. The cable that connects to it must end
in a DB-25 (25-pin) male connector. The cable is
a one-to-one wiring format. The pin assignments
for the serial port are:
