Oh, sorry to split that part
i'm using a GC-100-6, and i was trying use GCScan before, then i saw
on this forum that software don't work for RS232 -
i was trying send commands to the GC-100-6 via TCP/IP by iTest/GCScan,
and the GC-100-6 was connected to the receiver by RS232
Then i was trying send local commands by connecting the PC direct to
the receiver by RS232 because the hercules can't find the GC-100-6
when i connect pc via CAT-6 tcp/ip.
What i will try is, connect GC-100-6 in the receiver by CAT-6 and
connect my pc in the RS232 of GC-100-6 - what i think is a problem is
define tyhe port 4999 in hercules
