5.4.2 Using MicroProgrammer
CAUTION
It is important that communications be-
tween the Micro and the computer are not
disturbed during the software loading pro-
cess. If using a laptop computer, turn all en-
ergy saving features off. Turn off any screen
saver, or any hard drive time out settings.
New software can be installed using either the
preferred previously described Program PC
card method, or by using MicroProgrammer
3.14 and a computer. Existing Program PC
cards may be upgraded to 04.03.00 by using
the ReeferManager program.
Only
MicroProgrammer version 3.14 is to be
used to properly install new software. Earlier
versions of MicroProgrammer should be dis-
carded. MicroProgrammer ONLY RUNS ON
Windows 95/98.
It will NOT RUN on
Windows 2000 or XP.
a. Connect the computer to the microprocessor using a
Download Cable. Once the cable is connected to the
download port, the microprocessor will power up, and
show “PC MODE”.
b. Start the program by double clicking on the Micropro-
grammer icon on your computer desktop.
c. Click on the Load File button. The Open box will ap-
pear on the screen.
d. Using the mouse, select the file you want to load (this
will be a .bex file) by clicking once on it to highlight it.
e. Click the OK button. Watch the lower left message
area of the program. Once the file is validated, the
Program Micro button will become active.
f. Turn the RS switch to the Start/Run position. Wait for
the Main Display and MessageCenter to power up.
g. Click on the Program Micro button. The
MessageCenter will go blank. If the engine was run-
ning, it will shut down. Nothing will happen for the first
5--10 seconds, then the software will begin to load.
The Micro Status LED will start blinking at the rate of
.5 seconds on / .5 seconds off.
h. The % complete value on the computer screen will in-
crement itself as the program is loaded. The % com-
plete will stop several times during the loading pro-
cess for up to 15 seconds. This is normal. DO NOT
STOP THE PROCESS. The time to load the program
is dependent upon the speed of the computer. This
will generally take from 4 to 6 minutes.
i. It is important that the program is not interrupted from
the time the “Program Micro” button is clicked until the
program is completely loaded. Once the % complete
reaches 100%, the shutdown box will appear. Click
the OK button.
j.The microprocessor will power up, and the unit will
start. Allow the engine to start completely the first
time after loading software.
DO NOT TURN THE RS
SWITCH OFF DURING THE INITIAL START FOL-

5.4.3 Troubleshooting Software Loading
Problems
If
after
loading
the
software
program,
the
microprocessor does not power up, or the engine does
not start, use the following to isolate the problem.
a. Did the unit perform properly prior to loading the soft-
ware? If not, the problem most likely is not a result of
the software loading process.
b. Check the Micro Status LED near the PC Card slot on
the microprocessor. It should be blinking continuous-
ly at the rate of 1 second on and 1 second off. This is
the “normal” heartbeat rate of the microprocessor.
c. If the Micro Status LED is blinking at the rate of .5 sec-
onds on and .5 seconds off, the microprocessor is still
in Program Mode, and the software is not fully loaded
into memory. Load the software again, being careful
to follow each step completely in sequence.
d. If the Micro Status LED is not on at all, check voltage
to QC1 & QC2. Also check for voltage from the RS at
5MPA1. If voltage and grounds check OK, the micro-
processor may be dead and require replacement.
