Since SeaIOCU.exe must be executed from a command prompt, the easiest way to use it is to
copy SeaIOCU.exe and the hex file (in this example it is 420E.hex) to a subdirectory you create.
For this example, we will create a subdirectory called c:\seaiocu.
Click on Start, then click Run and type “cmd” (without the quotation marks and hit enter. You
will then see a command prompt (c:\documents and settings\name>).
Type
Cd \seaiocu and then press Enter
At this point, we assume the SeaIO 420 unit is set for 9600 baud and address 247 (the default
if the rotary switch is in position 0).
If you are connected either through a RS-232, RS-485, or USB connection then when the
command calls for nnn you substitute you com port number. Note that it MUST be 3 digits.
Therefore, if your com port is com5, you will enter 005. The command for this is therefore:
Seaiocu /c=005 /b=9600 /a=247 420e.hex
If you are connected through an Ethernet connection then when the command calls for
iii.iii.iii.iii you substitute the unit‟s IP address. Note that each group of numbers MUST be 3
digits. Therefore, if your IP address is 192.168.42.11, you will enter 192.168.042.011. The
command for this is therefore:
Seaiocu /i=192.168.042.011 /a=247 420e.hex
The first thing the SeaIO unit will do is to erase all of its flash memory (with the exception of a
small loader for the firmware). It will then start flashing all three lights rapidly indicating it
requires downloading. Once the download starts, one light will flash as data is downloaded.
Once the download is complete, the green light will remain on. At this point, simply unplug
power to the unit and when power is re-applied, you should be operational with the new
software.
In the event something about the download failed, the red light should stay on. In this case,
simply power down the unit and power it back up. It should now be flashing all three lights
rapidly. Simply perform the seaiocu command as described above.
The above should only be performed if you (1) really feel the update is required and (2)
you feel confident in your ability to perform the update. Once the firmware has been
erased, you must either be able to re-program it locally or send it back to SeaLevel
Systems, Inc. for reprogramming.
