Hello ahmelsayed. Here's hoping we can turn the :mad: into a :o
I suppose you are using the "Assign IP Address" option in PAC Manager
To quote from the "1704_PAC_Manager_Users_Guide.pdf"
If no MAC address appears, check the following:
• Is the Opto 22 device turned on? ("Yes, this has happened")
• Is it correctly connected to the PC using a crossover cable or correctly connected to an Ethernet hub using a straight-through cable? Is the PC on the same subnet as the device? See the PC’s user’s guide for networking information.
• Does the device already have an IP address? If you want to change the IP address, see section 4.
• Is the device booting to the loader rather than the firmware? See its user’s guide for more information.
• Does the PC have firewall software that blocks network broadcasts? If so, disable the firewall software. (For Windows XP SP2, click Unblock at the Windows Security Alert naming PAC Manager.)
You did not say if the brain is brand new or previously used. If it is brand new, it should not have an IP assigned (0.0.0.0). You can check this by looking at the LED STAT which should be blinking orange very fast meaning that no IP address is assigned to the controller. Only in this mode will the PAC-R1 actually be sending a BootP request, which needs to be picked up by the "Assign IP Address" function.
If this is not happening, it is because someone else has previously assigned an IP, and you will have to reset the PAC-R1 to default, a procedure explained in the section 4 of the the "1595_SNAP_PAC_R_series_Users_Guide.pdf"
If the PAC-R1 controller really is in this mode, and you are using a crossover cable, then the problem is that the communication is being blocked in your PC. This will either be a function of the windows firewall, third party firewalls, port blocking, administration lockdown software , anti virus software or maybe even all of them!
If all fails, contact your local Opto22 support centre or Product Support directly at Opto22. In this case its nice to have some remote administration software in your PC and an internet connection, as its pretty difficult to see what is going on in your PC by phone or email.
Waiting for your new post with a happy face. Maybe also tell us what was the real problem. Rarely is it the Opto22 hardware!
