Strange, it appears the driver is picking up a 16 port device rather than 8. Is it possible the EtherLite 8 has virtual ports configured in the firmware?

Yes, you are rigth, the Etherlite has 8 virtual port configured! Thanks
I resolve that, but i have another problems:
When i disconect the net wire, the Etherlite in the Digi Realport Manager continue with status Ready for a time.
After reconect the ports have strange behave, for example, my aplication that use the port thrown indefinitely an exception:
 No se puede serialEvent /dev/ttyca01. Input/output error in nativeavailable
I dont know whats happend, but the Etherlite in Centos 7 have not the same behavior that in Centos 5.
Sory for my English
