UPGRADING FIRMWARE VIA COMMAND PROMPT PROCEDURE
To execute IOCU.exe from a command prompt, Click on Start, then click Run and type “cmd” (without the
quotation marks) and hit ENTER. You will then see a command prompt (i.e. c:\documents and
settings\name>). Once you are at the command prompt, browse to your SeaMAX folder. The default
location is “C:\Program Files\Sealevel Systems\SeaMAX\” (or “C:\Program Files (x86)\Sealevel
Systems\SeaMAX” on 64-bit systems). Your *.hex file should be saved to this folder as well. If your
operating system requires administrator permissions for this action and you cannot provide them, another
folder outside the Program Files folder can be used, but a full path to the file will be required in the following
step.
Type
Cd “C:\Program Files\Sealevel Systems\SeaMAX\” and then press Enter
When the command calls for iii.iii.iii.iii you substitute the unit’s IP address. Please do not enter the numbers
with a leading zero. Therefore, if your IP address is 192.168.42.11, you will enter 192.168.42.11 and not
192.168.042.011. The command for this is therefore:
iocu /i=192.168.42.11 /a=247 120.hex
Once the unit has received the download request it will turn on the ACT light. Once the download starts, the
ACT light will flash rapidly as data is downloaded. Once the download is complete, the ACT light will remain
on while the device is reprogramming itself. The unit will then reboot itself to reload the new firmware. At
this point, the ACT light will turn off.
