RS-232 CONNECTIONS
The Sony disc changer is controlled via two-way serial protocols using an RS-232 serial cable. Connect the Sony changer to COM port “1 Changer”.
COM port “2 Auxiliary” is reserved for future use.
IR CONNECTIONS
The direct IR input jack on the back panel of the FireBall is for controlling FireBall from a wired IR distribution system such as a Xantech system.
This connection must be an IR signal with a 36kHz carrier using an 1/8” mono or stereo connector.
The IR input jack provides 12V power. This means that you can directly connect a 12V IR receiver (like the Xantech series 291 units) to the FireBall
using a 1/8” stereo connector.
ETHERNET CONNECTIONS
The Ethernet jack on the back panel of the FireBall accepts any standard twisted pair CAT5 Ethernet cable. If you are connecting FireBall to a home
network, you typically connect a standard Ethernet cable from your Ethernet
router or hub to the FireBall.
There are different grades, or categories, of twisted-pair cabling. Category 5
is the most reliable and widely compatible, and is highly recommended. It runs
easily with 10Mbps networks, and is required for 100Mbps networks. You can
buy Category 5 cabling that is pre-made, or you can cut & crimp your own.
Category 5 cables can be purchased or crimped as either straight-through or
crossed. A Category 5 cable has 8 thin, color-coded wires inside that run from
one end of the cable to the other. Only wires 1, 2, 3, and 6 are used by Ethernet
networks for communication. Although only four wires are used, if the cable has
8 wires, all the wires have to be connected in both jacks.
Straight-through cables are used for connecting computers to a hub. Crossed
cables are used for connecting a hub to another hub (there is an exception: some
hubs have a built-in uplink port that is crossed internally, which allows you to
uplink hubs together with a straight cable instead).
