Software upgrading
The software stored on the CPU can be upgraded to a newer
version through the RS232 serial port provided on the unit.
To perform this upgrade the following items are required:
- a PC
- a serial cable with 9 pin D type connectors, one male on
the equipment side, the female for the PC side. Wiring of
connectors must be 1:1 (pin 1 to pin 1, pin 2 to pin 2, etc.);
- the program “FlashPro32” to run under your PC, copies
available on request
- the latest version of software to upload into the PM740,
copies available on request
Upgrading procedure:
I) Switch OFF the PM740 - (Enable signal must be OFF).
II) Connect the serial cable to PC serial port and to RS232
serial port on the PM740.
III) Remove the top cover of the PM740.
IV) Locate the CPU board installed on the front panel and
set the programming switch to program.
V) Switch ON the PM740.
VI) Move the arm switch as indicated: The CPU is ready
to upload the new program into its “flash” memory:
this will cancel the existing program.
VII) Run the FlashPro and download from the PC the new
software: this will takes few minutes and FlashPro
will indicate the end of the upload.
VIII) During this operation the LCD will display a random
pattern. This is normal.
IX) When the procedure has been completed, return the
switch to its normal position.
X) Replace the cover of the PM740.
XI) Switch off the PM740 and wait 30 secs.
XII) Switch ON the PM740: one of the first messages will
