RS232
Instructions to install and operate the RS232 option follow.
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 in illustration following.
3. Mount the RS232 printed circuit board assembly using the screws or
standoffs provided. See illustration below.
4. Connect one end of the cable to J304 located on the left edge of the
left printed circuit board (p/n 3176707). Be careful of alignment.
5. Connect the other end of the cable to the cable connector on the
RS232 PCB assembly (see illustration).
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:
