Ethernet connection
For Ethernet connections, the GA-1120 supports Unshielded Twisted Pair (UTP)
cabling, defined as Category 5 for use with 100BaseT; or as Category 3, Category 4, or
Category 5 for use with 10BaseT. The cable uses an 8-pin RJ-45 connector that plugs
into the RJ-45 socket on the GA-1120.
NOTE:The 100BaseT type supported by the GA-1120 is 100BaseTX, also known as
Fast Ethernet. If an Ethernet hub is used, it must be a 100BaseTX hub. The term
“100BaseT” is used to refer to 100BaseTX.
TO CONNECT TO THE ETHERNET BOARD
• Connect the network cable to the RJ-45 connector on the back of the GA-1120.
You must use a Category 5 unshielded twisted pair cable network cable for 100BaseT.
Not used
